STPS1L60 Equivalent & Substitute Parts

Part Overview

The STPS1L60 is a Schottky rectifier diode rated for 60 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 axial package. Manufactured by STMicroelectronics, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the STPS1L60 is determined by the following critical parameters:

Electrical Requirements:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Technology: Schottky rectifier diode
Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Mechanical Requirements:

Mounting Type: Through Hole
Package / Case: DO-41 axial or equivalent through-hole axial package (DO-204AL)

Compliance & Status:

Product Status: Active (preferred for new designs)
RoHS Compliance: ROHS3 Compliant (preferred)

Substitute parts are grouped into two categories:

Direct Equivalents (Same Package DO-41/DO-204AL): Parts with identical or superior electrical ratings in the same through-hole axial package format.

Functional Equivalents (Alternative Axial Packages): Parts with identical or superior electrical ratings in through-hole axial packages that may differ in physical form factor but maintain electrical compatibility.

Engineering Selection Recommendations

Tier 1 - Direct Replacements (Preferred):

The following parts provide direct electrical and mechanical compatibility with the STPS1L60 in active product status:

10DQ06 (SMC Diode Solutions): Identical package (DO-41), active status, ROHS3 compliant. Vf is 700 mV at 1 A, which is within acceptable tolerance for Schottky rectifier applications.
SB160-E3/53 (Vishay General Semiconductor - Diodes Division): DO-204AL package (equivalent to DO-41), active status, ROHS3 compliant. Vf is 650 mV at 1 A, providing superior forward voltage performance.

Tier 2 - Functional Equivalents (Active Status, Compliance Considerations):

1N6759 (Microchip Technology): DO-41 package, active status. RoHS non-compliant; suitable for applications without RoHS requirements.
DSB1A60 (Microchip Technology): DO-204AL package, active status. RoHS non-compliant; suitable for applications without RoHS requirements.
MSG106 (Microsemi Corporation): DO-204AL package, active status, extended operating temperature range (-65°C to 175°C). RoHS non-compliant.

Tier 3 - Functional Equivalents (Axial Package Variants):

MBR160RLG (onsemi): Axial package, active status, ROHS3 compliant. Identical electrical ratings (60 V, 1 A). Physical form factor differs from DO-41 but maintains through-hole mounting compatibility.
MBR160G (onsemi): Axial package, active status, ROHS3 compliant. Identical electrical ratings (60 V, 1 A).

Tier 4 - Voltage-Reduced Alternative:

MBR150RLG (onsemi): 50 V rating (10 V lower than STPS1L60). Suitable only for applications with maximum operating voltage of 50 V or less. Active status, ROHS3 compliant.

Not Recommended:

SB160 (Fairchild Semiconductor): DO-15 package differs from DO-41 axial format; mechanical incompatibility with standard through-hole axial footprints.
11DQ06 (SMC Diode Solutions): 1.1 A rating exceeds application requirements; higher reverse leakage current (1 mA at 60 V) compared to STPS1L60 (50 µA at 60 V).

Frequently Asked Questions (FAQ)

Q: Can I use MBR150RLG as a direct replacement for STPS1L60?

A: MBR150RLG is not a direct replacement. It has a maximum reverse voltage rating of 50 V, which is 10 V lower than the STPS1L60's 60 V rating. Use MBR150RLG only in applications where the maximum operating voltage does not exceed 50 V.

Q: What is the difference between DO-41 and DO-204AL packages?

A: DO-41 and DO-204AL are equivalent designations for the same through-hole axial diode package. Both refer to a two-lead axial component with identical physical dimensions and footprint compatibility.

Q: Are axial package variants (MBR160RLG, MBR160G) compatible with STPS1L60 footprints?

A: Yes. Axial package variants maintain the same through-hole mounting configuration and lead spacing as DO-41/DO-204AL packages. They are mechanically and electrically compatible with STPS1L60 PCB footprints.

Q: Why is RoHS compliance important for selecting a substitute?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. For new designs and applications subject to regulatory requirements, ROHS3-compliant parts (10DQ06, SB160-E3/53, MBR160RLG, MBR160G) are required. Non-compliant parts (1N6759, DSB1A60, MSG106) are suitable only for applications without RoHS mandates.

Q: What does "Fast Recovery ≤ 500 ns, > 200 mA (Io)" mean?

A: This specifies the diode's reverse recovery time is 500 nanoseconds or less when switching from forward conduction at currents exceeding 200 mA. All listed substitute parts meet this specification, ensuring compatibility in high-frequency switching applications.

Q: Can I use 11DQ06 (1.1 A) instead of STPS1L60 (1 A)?

A: 11DQ06 has a higher current rating (1.1 A) and can handle the 1 A requirement of STPS1L60. However, 11DQ06 has significantly higher reverse leakage current (1 mA at 60 V versus 50 µA at 60 V for STPS1L60). Use 11DQ06 only if the application tolerates higher leakage current.

Q: What is the significance of forward voltage (Vf) differences among substitutes?

A: Forward voltage differences (ranging from 570 mV to 760 mV at 1 A) affect power dissipation and circuit performance. Lower Vf values (SB160-E3/53 at 650 mV) reduce heat generation. Higher Vf values (11DQ06 at 760 mV) increase power loss. Select based on thermal and efficiency requirements of the application.

Q: Is SB160 (DO-15 package) a suitable replacement?

A: SB160 has different package geometry (DO-15 versus DO-41). While electrically compatible, the DO-15 package is not mechanically compatible with standard DO-41 axial footprints. Use SB160 only if the PCB layout accommodates DO-15 package dimensions.

Q: What product status should I prioritize for new designs?

A: For new designs, select parts with "Active" product status. Active parts ensure long-term availability and manufacturer support. The STPS1L60 is obsolete; all recommended substitutes are active products.
