SS36-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS36-HF is a Schottky rectifier diode manufactured by Comchip Technology, rated for 60V DC reverse voltage and 3A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements permit operation within specified electrical and mechanical parameter ranges, or when supply chain considerations necessitate alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS36-HF are qualified based on the following criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Package / Case: DO-214AC, SMA (surface mount)
• Technology: Schottky
• Voltage - Forward (Vf) (Max): 700 mV
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variation:

• Current - Average Rectified (Io): Substitute parts rated at 1A or 2A are acceptable where circuit design permits operation at reduced current ratings
• Current - Reverse Leakage @ Vr: Variation within 400–500 µA @ 60 V is acceptable
• Operating Temperature - Junction: Extended ranges (-65°C to 150°C) are acceptable
• Capacitance @ Vr, F: Variation or undocumented values do not disqualify substitution

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

CMSH1-60M TR13 PBFREE (Central Semiconductor Corp)

This substitute is suitable for applications where the circuit design accommodates a 1A average rectified current rating. The part maintains identical voltage specifications (60V reverse, 700mV forward) and fast recovery characteristics. Operating temperature range extends to -65°C to 150°C, providing broader thermal coverage than the primary part. ROHS3 compliance and MSL 1 rating match the SS36-HF. This part is recommended for lower-current circuit branches or where thermal margin is not a limiting factor.

SS26S-M3/61T (Vishay General Semiconductor - Diodes Division)

This substitute is suitable for applications where the circuit design accommodates a 2A average rectified current rating. The part maintains identical voltage specifications (60V reverse, 700mV forward) and fast recovery characteristics. Reverse leakage current is 400 µA @ 60V, which is lower than the primary part's 500 µA specification. Operating temperature range extends to -65°C to 150°C. ROHS3 compliance and MSL 1 rating match the SS36-HF. This part is recommended for mid-range current applications or where improved leakage performance is beneficial.

Both substitute parts are Active status products from established manufacturers with full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can CMSH1-60M TR13 PBFREE replace SS36-HF in all applications?

A: CMSH1-60M TR13 PBFREE is a direct substitute only in circuits designed for 1A or lower average rectified current. If the circuit requires 3A operation, this part is not suitable. Voltage, package, and thermal characteristics are compatible.

Q: Can SS26S-M3/61T replace SS36-HF in all applications?

A: SS26S-M3/61T is a direct substitute only in circuits designed for 2A or lower average rectified current. If the circuit requires 3A operation, this part is not suitable. Voltage, package, and thermal characteristics are compatible.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is current rating. CMSH1-60M TR13 PBFREE is rated for 1A, while SS26S-M3/61T is rated for 2A. Both maintain the same 60V reverse voltage and 700mV forward voltage specifications as the SS36-HF.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-214AC (SMA) surface mount package with identical pinout and footprint.

Q: Do the substitute parts have different temperature operating ranges?

A: Yes. The SS36-HF operates from -55°C to 125°C. Both substitute parts extend the lower limit to -65°C and upper limit to 150°C, providing broader thermal coverage.

Q: Are there any compliance or regulatory differences?

A: No. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified as Active products. Both substitute parts include REACH Unaffected status documentation.

Q: What is the reverse leakage current difference?

A: SS36-HF and CMSH1-60M TR13 PBFREE both specify 500 µA @ 60V. SS26S-M3/61T specifies 400 µA @ 60V, representing lower leakage performance.

Q: Can I use a substitute part rated for lower current in a 3A circuit?

A: No. Using a part rated for 1A or 2A in a circuit requiring 3A operation will result in component overstress, reduced reliability, and potential failure.
