Engineering Selection Recommendations

All three parts—SS8P5CHM3_A/I, SS8P5C-M3/86A, and SS8P6CHM3_A/H—are active products manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and mechanical specifications. Selection between these parts is based on packaging format and inventory availability:

SS8P5CHM3_A/I: Primary specification with Tape & Reel (TR) packaging. Automotive-grade qualification (AEC-Q101) is specified. Current inventory: 820 Pcs.

SS8P5C-M3/86A: Parametric equivalent with Tape & Reel (TR) packaging. Automotive-grade qualification is not specified in the provided data. Current inventory: 12,300 Pcs. This part offers higher inventory availability.

SS8P6CHM3_A/H: Parametric equivalent with Cut Tape (CT) packaging. Automotive-grade qualification (AEC-Q101) is specified. Current inventory: 3,716 Pcs. This part differs in packaging format and base product number (SS8P6 versus SS8P5).

All parts comply with ROHS3 and REACH requirements. Selection should account for packaging requirements (Tape & Reel versus Cut Tape), automotive qualification necessity, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SS8P5C-M3/86A be used as a direct replacement for SS8P5CHM3_A/I?

A: Yes. Both parts share identical electrical parameters (50 V reverse voltage, 4 A current rating, 700 mV forward voltage at 4 A, 50 µA reverse leakage at 50 V), identical diode configuration (1 Pair Common Cathode), identical package (TO-277, 3-PowerDFN), and identical operating temperature range (-55°C ~ 150°C). Both are Schottky technology with fast recovery characteristics. The primary difference is packaging format (Tape & Reel for both) and automotive qualification specification.

Q: What is the difference between SS8P6CHM3_A/H and SS8P5CHM3_A/I?

A: The electrical and mechanical parameters are identical. Both parts are rated for 50 V, 4 A, with 700 mV forward voltage and 50 µA reverse leakage. Both use TO-277, 3-PowerDFN packages and operate across -55°C ~ 150°C. The difference lies in the base product number (SS8P6 versus SS8P5) and packaging format (Cut Tape for SS8P6CHM3_A/H versus Tape & Reel for SS8P5CHM3_A/I).

Q: Are there packaging format differences between these substitute parts?

A: Yes. SS8P5CHM3_A/I and SS8P5C-M3/86A are supplied in Tape & Reel (TR) format. SS8P6CHM3_A/H is supplied in Cut Tape (CT) format. The physical component and electrical performance are identical; packaging format selection depends on assembly process requirements and handling procedures.

Q: Do all substitute parts meet automotive qualification requirements?

A: SS8P5CHM3_A/I and SS8P6CHM3_A/H are specified with AEC-Q101 automotive qualification. SS8P5C-M3/86A does not list automotive qualification in the provided specifications. If automotive qualification is a design requirement, SS8P5CHM3_A/I or SS8P6CHM3_A/H must be selected.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting environmental regulatory requirements.
