Substitute Part Grouping Explanation

Substitute parts for the SS36B-HF are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 700 mV @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 500 µA @ 60 V
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in capacitance at specified conditions and packaging format (Cut Tape, Digi-Reel, or Tape & Reel) do not affect functional equivalence for rectification applications.

Engineering Selection Recommendations

All substitute parts listed are Active product status and meet RoHS3 compliance requirements. Selection among equivalent parts is determined by packaging format availability and supply chain requirements:

B360B-13-F (Diodes Incorporated): Available in Cut Tape (CT) and Digi-Reel® packaging. Carries AEC-Q101 automotive qualification and REACH Unaffected status. Suitable for applications requiring automotive-grade components.

B360BQ-13-F (Diodes Incorporated): Available in Tape & Reel (TR) packaging. Carries AEC-Q101 automotive qualification and REACH Unaffected status. Packaging format matches the original SS36B-HF specification.

SS36B (MDD): Available in SMB series designation. REACH Unaffected status. Capacitance specification of 400 pF @ 4V, 1MHz falls between the Comchip original and Diodes Incorporated alternatives.

All parts maintain identical electrical performance for 60 V / 3 A Schottky rectification applications. Selection is based on packaging availability, inventory status, and compliance certifications required by the end application.

Frequently Asked Questions (FAQ)

Q: Can B360B-13-F replace SS36B-HF in production?

A: Yes. B360B-13-F meets all critical electrical parameters: 60 V reverse voltage, 3 A average rectified current, 700 mV forward voltage at 3 A, fast recovery speed, and identical leakage current. Both are RoHS3 compliant with MSL 1. Packaging is DO-214AA (SMB) surface mount. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and automotive qualification (AEC-Q101).

Q: What is the difference between B360B-13-F and B360BQ-13-F?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. The difference is packaging format: B360B-13-F is supplied in Cut Tape (CT) and Digi-Reel®, while B360BQ-13-F is supplied in Tape & Reel (TR). Both carry AEC-Q101 automotive qualification.

Q: Does capacitance variation affect substitution?

A: Capacitance values (450 pF for SS36B-HF, 200 pF for B360B-13-F and B360BQ-13-F, 400 pF for SS36B) are specified at 4 V and 1 MHz. These variations do not affect rectification performance in standard power supply and switching applications. Capacitance becomes relevant only in high-frequency or RF applications where junction capacitance impacts circuit behavior.

Q: Are all substitute parts surface mount compatible?

A: Yes. All parts use DO-214AA (SMB) surface mount package with identical mounting type and footprint. No PCB layout changes are required for substitution.

Q: What is the operating temperature range for all parts?

A: All parts operate across -55°C to 150°C junction temperature range, supporting industrial and automotive temperature requirements.

Q: Do substitute parts require moisture sensitivity precautions?

A: No. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.
