Equivalent & Substitute Parts for SS16/1 Schottky Diode

Part Overview

The SS16/1 is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 60 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMA) package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while meeting modern compliance standards.

Substitute Part Grouping Explanation

Substitute parts for the SS16/1 are grouped based on strict electrical and mechanical compatibility criteria. All substitute Schottky diodes must satisfy the following requirements:

Primary Compatibility Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V minimum
Current - Average Rectified (Io): 1 A minimum
Mounting Type: Surface Mount
Package / Case: DO-214AC or SMA equivalent
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Considerations:

Forward voltage (Vf) at rated current
Reverse leakage current (Ir) at rated voltage
Operating temperature range
RoHS compliance status
Product status (Active preferred over Discontinued or Not For New Designs)

Parts are classified into two categories: direct electrical equivalents (matching all primary parameters) and functional substitutes (meeting or exceeding primary parameters with acceptable variations in secondary characteristics).

Engineering Selection Recommendations

Tier 1 - Direct Equivalents (Preferred for Replacement):

SS16-E3/61T (Vishay General Semiconductor) and B160-E3/61T (Vishay General Semiconductor) are direct electrical and mechanical equivalents to the SS16/1. Both parts maintain identical voltage, current, and forward voltage specifications while offering ROHS3 compliance and active product status. SS16-E3/61T is the manufacturer-recommended replacement with significantly higher inventory availability (153,834 units).

Tier 2 - Functional Equivalents (Compatible Substitutes):

B160-13-F (Diodes Incorporated), SS16T3G (onsemi), and SS16_R1_00001 (Panjit International Inc.) meet all primary electrical requirements with minor variations in forward voltage or reverse leakage current within acceptable engineering tolerances. All three maintain 60 V reverse voltage, 1 A average rectified current, and DO-214AC (SMA) packaging. These parts are active and ROHS3 compliant.

SS16 (EVVO Semi) is functionally compatible but operates at a reduced maximum junction temperature of 125°C compared to the original 150°C specification.

Tier 3 - Higher Current Capability:

ACDBA360-HF (Comchip Technology) provides 3 A average rectified current in the same DO-214AC (SMA) package, suitable for applications requiring higher current capacity. This part is AEC-Q101 qualified for automotive applications and ROHS3 compliant. Maximum junction temperature is 125°C.

Not Recommended for New Designs:

RB162L-60TE25 (Rohm Semiconductor) carries a "Not For New Designs" status and should not be selected for new applications despite meeting electrical specifications.

SS16 R3G (Taiwan Semiconductor Corporation) is discontinued at DiGi Electronics and should not be used for ongoing production.

Frequently Asked Questions (FAQ)

Q: Can I use ACDBA360-HF as a direct replacement for SS16/1?

A: ACDBA360-HF is electrically compatible but rated for 3 A average rectified current versus the 1 A specification of SS16/1. It operates at a lower maximum junction temperature (125°C vs. 150°C). Use ACDBA360-HF only if the application circuit can accommodate the higher current rating and lower temperature limit.

Q: What is the difference between SS16-E3/61T and B160-E3/61T?

A: Both parts are manufactured by Vishay General Semiconductor and share identical electrical specifications (60 V, 1 A, 750 mV forward voltage). The primary difference is the base product number designation (SS16 vs. B160). Both are ROHS3 compliant and active. SS16-E3/61T has significantly higher inventory availability.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts except the original SS16/1 are ROHS3 compliant. The SS16/1 is listed as RoHS non-compliant. For applications requiring RoHS compliance, select from the active substitute parts listed in Tier 1 or Tier 2.

Q: Does package type affect substitution?

A: All substitute parts use DO-214AC (SMA) surface mount packaging, which is mechanically and electrically compatible with the original SS16/1. Packaging variations (Cut Tape, Digi-Reel, Tape & Reel) affect supply chain logistics but not component functionality.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" (such as RB162L-60TE25) are typically in end-of-life phases and may have limited future availability or support. These parts should not be selected for new product development, though they may be acceptable for legacy system maintenance if no alternatives exist.

Q: Can I substitute based on forward voltage alone?

A: No. Forward voltage is one of several critical parameters. All substitute parts must maintain the 60 V reverse voltage rating and 1 A current rating as minimum requirements. Forward voltage variations (650 mV to 750 mV) are acceptable within the Schottky diode technology range, but voltage and current ratings are non-negotiable for safe circuit operation.

Q: What is the operating temperature range consideration?

A: The original SS16/1 operates from -65°C to 150°C. Most substitute parts operate from -55°C to 150°C, which is acceptable for most industrial and commercial applications. ACDBA360-HF and EVVO Semi SS16 are limited to -55°C to 125°C. Verify application requirements before selecting parts with reduced temperature ranges.

Q: Why does reverse leakage current vary among substitutes?

A: Reverse leakage current (Ir) varies due to manufacturing process differences between manufacturers. The original SS16/1 specifies 200 µA @ 60 V. Substitutes range from 100 µA to 500 µA. Higher leakage current increases power dissipation in reverse bias conditions. Select parts with lower leakage current for low-power or precision applications.
