SSA36 Schottky Diode 60V 3A Equivalent & Substitute Parts

Part Overview

The SSA36 is a Schottky rectifier diode manufactured by onsemi, rated for 60V reverse voltage and 3A average rectified current in a DO-214AC (SMA) surface mount package.

Engineering Selection Recommendations

For Direct Replacement (60V/3A Applications):

The following parts provide full parametric equivalence to the SSA36 and are suitable for direct substitution in existing designs:

B360AM-13-F (Diodes Incorporated): Active product status with Automotive grade and AEC-Q101 qualification. Forward voltage is 50 mV lower than SSA36 (700 mV vs 750 mV @ 3A), resulting in improved efficiency. Reverse leakage is identical at 100 µA @ 60V. Recommended for new production due to active status and automotive qualification.
SK36AHE3-LTP (Micro Commercial Co): Active product with Automotive grade and AEC-Q101 qualification. Electrical parameters match SSA36 exactly (750 mV forward voltage, 100 µA reverse leakage). High inventory availability (500,100 pcs) supports supply chain continuity.
SX36_R1_00001 (Panjit International Inc.): Active product with identical electrical specifications to SSA36. Moderate inventory (18,000 pcs) available. No automotive grade designation.
SX36-AU_R1_000A1 (Panjit International Inc.): Active product with Automotive grade and AEC-Q101 qualification. Electrical parameters match SSA36 exactly. Lower inventory (2,052 pcs) compared to other equivalents.
B360A-13-F (Diodes Incorporated): Active product with Automotive grade and AEC-Q101 qualification. Forward voltage is 50 mV lower than SSA36. Reverse leakage is 500 µA @ 60V (5x higher than SSA36). High inventory (285,400 pcs) supports supply availability. Suitable where higher leakage current is acceptable.

For Current-Reduced Applications:

B260AQ-13-F or B260A-13-F (2A rating): Suitable only for applications where actual circuit current does not exceed 2A. Both parts maintain 60V voltage rating and DO-214AC package compatibility.
B160Q-13-F or B160-13-F (1A rating): Suitable only for applications where actual circuit current does not exceed 1A. Both parts maintain 60V voltage rating and DO-214AC package compatibility.

For Intermediate Current Applications:

VSSA3L6S-M3/61T (Vishay, 2.5A rating): Suitable for applications requiring current between 2A and 3A. Forward voltage is significantly lower (580 mV @ 3A), providing improved efficiency. Reverse leakage is substantially higher (1.5 mA @ 60V), which may impact standby power consumption in certain applications.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080, matching the SSA36 regulatory profile. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a lower current-rated diode (1A or 2A) as a substitute for the SSA36 (3A)?

A: No. Lower current-rated diodes cannot be used as direct substitutes. The current rating represents the maximum average rectified current the diode can safely conduct. Using an undersized diode in a 3A application will cause excessive junction temperature rise and premature failure. Lower-rated parts are suitable only if the actual circuit current requirement is confirmed to be below their rating.

Q: What is the difference between B360A-13-F and B360AM-13-F?

A: Both parts are 60V/3A Schottky diodes from Diodes Incorporated with identical voltage ratings and current capacity. The primary differences are: B360AM-13-F is supplied in Tape & Reel (TR) packaging, while B360A-13-F is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both have forward voltage of 700 mV @ 3A. B360A-13-F has higher reverse leakage (500 µA vs 100 µA @ 60V). Selection depends on assembly process requirements and acceptable leakage current for the application.

Q: Is the SSA36 still available for new designs?

A: No. The SSA36 is classified as Not For New Designs, indicating end-of-life status. For new designs, select from the active substitute parts listed, such as B360AM-13-F, SK36AHE3-LTP, or SX36_R1_00001, which provide equivalent or superior electrical performance with active product status.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard. Parts bearing this qualification have undergone rigorous testing for reliability and performance in automotive applications. For applications requiring automotive-grade components, select parts with AEC-Q101 qualification: B360AM-13-F, B360A-13-F, SK36AHE3-LTP, SX36-AU_R1_000A1, B260AQ-13-F, or B160Q-13-F.

Q: Can I substitute the SSA36 with VSSA3L6S-M3/61T (2.5A)?

A: VSSA3L6S-M3/61T is suitable only if the actual circuit current does not exceed 2.5A. The part provides 60V voltage rating and DO-214AC package compatibility. However, forward voltage is significantly lower (580 mV vs 750 mV @ 3A), and reverse leakage is substantially higher (1.5 mA vs 100 µA @ 60V). These differences may affect circuit performance, particularly in applications sensitive to forward voltage drop or standby leakage current. Circuit analysis is required to confirm suitability.

Q: Are all substitute parts available in the same DO-214AC (SMA) package?

A: Yes. All substitute parts listed are available in DO-214AC (SMA) surface mount package, ensuring mechanical and footprint compatibility with the SSA36. Packaging format (Cut Tape vs Tape & Reel) varies by part number and supplier, but the physical component package remains identical.

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

A: Forward voltage determines the voltage drop across the diode during conduction. Lower forward voltage reduces power dissipation and improves circuit efficiency. The SSA36 has 750 mV forward voltage @ 3A. Substitutes with lower Vf (such as B360AM-13-F at 700 mV or VSSA3L6S-M3/61T at 580 mV) will reduce heat generation. In high-current or high-frequency applications, this difference becomes significant. In low-current applications, the difference is negligible.

Q: What is reverse leakage current and why does it matter?

A: Reverse leakage current (Ir) is the small current that flows through the diode when reverse-biased. The SSA36 has 100 µA @ 60V. Some substitutes have higher leakage (up to 1.5 mA for VSSA3L6S-M3/61T). Higher leakage increases standby power consumption and heat generation. In battery-powered or low-power applications, this becomes critical. For general-purpose rectification, the difference is typically acceptable.

Q: Can I use B360A-13-F (Cut Tape packaging) and B360AM-13-F (Tape & Reel packaging) interchangeably?

A: The electrical and mechanical specifications are equivalent, but packaging format differs. Cut Tape & Digi-Reel® packaging is suitable for manual assembly or lower-volume production. Tape & Reel packaging is optimized for automated pick-and-place assembly. Selection depends on manufacturing process. The physical component is identical; only the supply format differs.

Q: What is the operating temperature range and why is it important?

A: The SSA36 operates from -55°C to 150°C junction temperature. Most substitutes maintain this range or extend it to -65°C. Operating temperature range defines the environment in which the diode functions reliably. For applications in extreme temperature environments (automotive underhood, industrial), confirm the substitute part's temperature range matches or exceeds the SSA36 specification.
