Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VS-4CSH02HM3/86A are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io) (per Diode): 2 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
• Reverse Recovery Time (trr): 16 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 200 V

Mechanical & Configuration Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C ~ 175°C

Compliance & Qualification:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The VS-4CSH02-M3/86A meets all specified criteria and is therefore a valid substitute.

Parameter Comparison

Engineering Selection Recommendations

The VS-4CSH02-M3/86A is a parametric equivalent substitute for the VS-4CSH02HM3/86A. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, package configuration, and operating characteristics.

Selection Basis:

Both parts are Active products with ROHS3 compliance and REACH Unaffected status. The VS-4CSH02-M3/86A maintains all critical electrical parameters including 200 V reverse voltage rating, 2 A average rectified current, 950 mV forward voltage drop at 2 A, and 16 ns reverse recovery time. The identical TO-277, 3-PowerDFN surface mount package ensures mechanical and thermal compatibility in existing PCB designs.

The substitute part is suitable for direct replacement in applications where the main part number is specified, subject to design verification and supply chain requirements. Both components operate across the -65°C to 175°C junction temperature range and are part of the FRED Pt® fast recovery diode series.

Frequently Asked Questions (FAQ)

Q: Can VS-4CSH02-M3/86A be used as a direct replacement for VS-4CSH02HM3/86A?

A: Yes. The VS-4CSH02-M3/86A is a parametric equivalent with identical electrical specifications, diode configuration, package type, and operating temperature range. Both components are manufactured by Vishay and share the same base product number (4CSH02).

Q: Are the package dimensions identical between these two parts?

A: Yes. Both parts use the TO-277, 3-PowerDFN surface mount package with TO-277A (SMPC) supplier device package designation. PCB footprints and thermal characteristics are equivalent.

Q: What is the difference between the part numbers VS-4CSH02HM3/86A and VS-4CSH02-M3/86A?

A: The part numbers differ in their suffix designations (HM3 versus -M3), which typically indicate different manufacturing batches, date codes, or internal Vishay product line variations. The electrical and mechanical specifications are identical.

Q: Are both parts automotive-grade qualified?

A: The VS-4CSH02HM3/86A carries explicit Automotive grade designation with AEC-Q101 qualification. The VS-4CSH02-M3/86A specification data provided does not explicitly state automotive grade or AEC-Q101 qualification, though both parts are from the same manufacturer and series.

Q: What is the reverse recovery time specification, and why is it important?

A: Both parts specify a reverse recovery time (trr) of 16 ns. This parameter indicates the time required for the diode to switch from forward conduction to reverse blocking state. Fast recovery characteristics (≤500 ns) are critical for high-frequency switching applications and power conversion circuits.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for junction temperatures up to 175°C and operate across the -65°C to 175°C range, supporting automotive and industrial high-temperature environments.

Q: What is the moisture sensitivity level, and what does it mean?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates Unlimited shelf life. No special moisture control measures are required during storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.
