SS36 Schottky Diode 60V 3A SMC Equivalent & Substitute Parts

Part Overview

The onsemi SS36 is a Schottky rectifier diode rated for 60V DC reverse voltage and 3A average rectified current in a Surface Mount SMC (DO-214AB) package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product portfolio. The fast recovery characteristic (≤500ns at >200mA) makes it suitable for switching power supply and rectification applications requiring low forward voltage drop and rapid switching performance.

Identifying equivalent and substitute parts is necessary due to the obsolescence status of the SS36, which may result in limited availability or discontinuation. Direct electrical and mechanical equivalents with active product status provide design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the SS36 is determined by strict electrical and mechanical parameter matching within the Schottky diode rectifier category. The following criteria establish substitution validity:

Primary Substitution Criteria (Mandatory Match):

Voltage - DC Reverse (Vr) Maximum: 60V
Current - Average Rectified (Io): 3A
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤500ns at >200mA

Secondary Compatibility Parameters:

Operating Temperature Range: Minimum -55°C to maximum 150°C or wider
Forward Voltage (Vf): 700–750mV @ 3A (acceptable range for functional equivalence)
Reverse Leakage Current: ≤500µA @ 60V
RoHS3 Compliance: Required

Substitute parts are classified into two groups:

Group 1 - Direct Electrical Equivalents (3A @ 60V): Parts meeting all primary criteria with identical current and voltage ratings. These include SK36-TP, SS36-E3/57T, B360-13-F, B360Q-13-F, CDBC360-G, MB36_R1_00001, STPS3L60S, and STPS3L60SY.

Group 2 - Higher Current Capability (5A @ 60V): Parts exceeding the 3A requirement while maintaining 60V rating. These include B560C-13-F and B560CQ-13-F. These are suitable for applications where the SS36 is used below its maximum current rating and where higher current headroom is beneficial.

Engineering Selection Recommendations

For Direct Replacement (Active Product Status):

The SS36-E3/57T (Vishay General Semiconductor - Diodes Division) is the primary recommended substitute. It maintains identical electrical specifications (60V, 3A, 750mV forward voltage) and package configuration (DO-214AB, SMC) with Active product status, ensuring long-term availability and supply chain continuity. This part is available in Cut Tape and Digi-Reel packaging, matching the original SS36 distribution format.

For Cost-Optimized Selection (Active Product Status):

The B360-13-F (Diodes Incorporated) and STPS3L60S (STMicroelectronics) provide equivalent electrical performance with a lower forward voltage specification (700mV @ 3A versus 750mV), resulting in reduced power dissipation. Both parts maintain 60V/3A ratings, DO-214AB packaging, and Active product status. B360-13-F is available in Cut Tape format; STPS3L60S is available in Cut Tape & Digi-Reel format.

For Automotive Applications (AEC-Q101 Qualified):

The B360Q-13-F and B560CQ-13-F (Diodes Incorporated) are AEC-Q101 qualified alternatives suitable for automotive-grade applications. B360Q-13-F provides direct 3A equivalence; B560CQ-13-F offers 5A capability with the same 60V rating. Both are available in Tape & Reel packaging and carry Active product status.

For Higher Current Margin (Active Product Status):

The B560C-13-F and B560CQ-13-F (Diodes Incorporated) provide 5A average rectified current at 60V, offering increased current headroom for applications where the SS36 operates below maximum rating. These parts are electrically compatible and suitable for designs requiring additional thermal margin or future current scaling.

For Low Reverse Leakage Applications:

The MB36_R1_00001 (Panjit International Inc.) exhibits significantly lower reverse leakage current (50µA @ 60V versus 500µA), making it suitable for precision rectification circuits where leakage current is a design constraint. This part is available in Tape & Reel packaging with Active product status and an extended operating temperature range (-65°C to 175°C).

Avoid Selection:

SK36-TP (Micro Commercial Co) carries Obsolete product status and should not be selected for new designs or long-term supply requirements, despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SS36-E3/57T directly replace the SS36 without circuit modification?

A: Yes. The SS36-E3/57T maintains identical electrical specifications (60V reverse voltage, 3A average rectified current, 750mV forward voltage @ 3A) and identical package configuration (DO-214AB, SMC). No circuit modification is required. The part is pin-compatible and functionally equivalent.

Q: What is the difference between B360-13-F and SS36-E3/57T?

A: Both parts are rated 60V/3A in DO-214AB packaging. The primary difference is forward voltage specification: B360-13-F is rated 700mV @ 3A, while SS36-E3/57T is rated 750mV @ 3A. The lower forward voltage of B360-13-F results in reduced power dissipation. Both are Active products from different manufacturers (Diodes Incorporated versus Vishay).

Q: Can B560C-13-F be used as a substitute for SS36?

A: Yes, with design consideration. B560C-13-F is rated 60V/5A, exceeding the SS36's 3A specification. It is electrically compatible and can be used in applications where the SS36 operates below maximum current rating. The higher current rating provides additional thermal margin and design flexibility. Thermal and PCB layout should be verified for the specific application.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Both are surface mount tape formats suitable for automated assembly. Cut Tape & Digi-Reel® is supplied on standard tape that can be cut to length for manual or small-batch assembly. Tape & Reel (TR) is supplied on full reels for high-volume automated production. Electrical and mechanical specifications are identical; packaging format selection depends on production volume and assembly equipment.

Q: Are B360Q-13-F and STPS3L60SY suitable for automotive applications?

A: B360Q-13-F is AEC-Q101 qualified and explicitly designated for automotive applications. STPS3L60SY carries an Automotive grade designation but does not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring formal qualification, B360Q-13-F is the specified choice.

Q: What is the significance of the lower reverse leakage current in MB36_R1_00001?

A: MB36_R1_00001 exhibits 50µA reverse leakage @ 60V compared to 500µA in the SS36. Lower reverse leakage is beneficial in precision rectification circuits, battery charging applications, and low-power standby circuits where leakage current directly impacts efficiency or measurement accuracy. This part is suitable for applications where leakage current is a design constraint.

Q: Is the SS36 still available for purchase?

A: The SS36 is classified as "Not For New Designs" with 103,100 pieces reported in stock. While current inventory exists, this status indicates the manufacturer has superseded the part. Long-term availability is not guaranteed. Selection of an Active product status substitute (such as SS36-E3/57T, B360-13-F, or STPS3L60S) is recommended for new designs and ongoing production.

Q: What is the operating temperature range difference between MB36_R1_00001 and SS36?

A: MB36_R1_00001 operates from -65°C to 175°C, while SS36 operates from -55°C to 150°C. MB36_R1_00001 provides extended low-temperature operation (-65°C versus -55°C) and extended high-temperature operation (175°C versus 150°C). This extended range is beneficial for applications in extreme thermal environments.

Q: Can multiple substitute parts be used interchangeably in the same design?

A: Yes, within the constraints of electrical specifications. All listed 3A/60V substitutes (SS36-E3/57T, B360-13-F, CDBC360-G, MB36_R1_00001, STPS3L60S, STPS3L60SY) are electrically compatible and pin-compatible in DO-214AB packaging. Forward voltage variations (700–750mV) are within acceptable tolerance for most rectification applications. Thermal design and reverse leakage considerations should be evaluated for the specific application. The 5A parts (B560C-13-F, B560CQ-13-F) are also compatible but provide higher current capability.
