• Current - Average Rectified (Io) (per Diode): 20 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Packaging format (Tape & Reel, Cut Tape & Digi-Reel®, Tube)
• Forward voltage (Vf) within application tolerance
• Maximum junction temperature rating
• Automotive grade and AEC-Q101 qualification (enhancement, not requirement)
• Current - Reverse Leakage @ Vr (lower values acceptable)

All substitute parts listed maintain identical electrical performance within the specified operating parameters and are mechanically compatible with the original part footprint.

Parameter Comparison

Engineering Selection Recommendations

Vishay VB40100C-E3/8W: This part is a parametric equivalent to the VB40100C-M3/8W with identical electrical specifications and operating temperature range. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Selection is appropriate when Cut Tape packaging is required for manufacturing processes or when higher inventory availability is needed.

STMicroelectronics STPS41H100CG: This part meets all critical electrical and mechanical equivalence parameters. Forward voltage is specified at 800 mV versus 730 mV for the Vishay part, which is within typical application tolerance. Reverse leakage current is lower (10 µA versus 1 mA), representing improved performance. Maximum junction temperature is 175°C. Packaging is supplied in Tube format. Selection is appropriate for applications where STMicroelectronics supply chain preference exists or when lower reverse leakage is beneficial.

STMicroelectronics STPS41H100CG-TR: This part is electrically identical to STPS41H100CG with Cut Tape & Digi-Reel® packaging. Automotive grade designation and AEC-Q101 qualification are specified. Maximum junction temperature is 175°C. Selection is appropriate for automotive applications requiring AEC-Q101 qualified components or when Cut Tape packaging is required.

STMicroelectronics STPS41H100CGY-TR: This part is electrically identical to STPS41H100CG-TR with specified operating temperature range of -40°C to 175°C. Automotive grade designation and AEC-Q101 qualification are specified. Cut Tape & Digi-Reel® packaging is provided. Selection is appropriate for automotive applications with extended temperature requirements or when full temperature range specification is mandated.

All substitute parts are Active product status and ROHS3 compliant. Selection among substitutes is determined by packaging format requirements, supply chain preferences, automotive qualification necessity, and temperature range specifications.

Frequently Asked Questions (FAQ)

Q: Can VB40100C-E3/8W be used as a direct replacement for VB40100C-M3/8W?

A: Yes. VB40100C-E3/8W is a parametric equivalent with identical electrical specifications, diode configuration, voltage rating, current rating, and operating temperature range. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Mechanical compatibility and PCB footprint are identical.

Q: What is the difference between Vishay and STMicroelectronics versions?

A: Both manufacturers provide Schottky diode arrays with identical 100 V, 20 A ratings and TO-263-3 D2PAK packaging. STMicroelectronics parts specify forward voltage at 800 mV versus Vishay's 730 mV, and lower reverse leakage current (10 µA versus 1 mA). STMicroelectronics STPS41H100CG-TR and STPS41H100CGY-TR include automotive grade and AEC-Q101 qualification. Maximum junction temperature for STMicroelectronics parts is 175°C versus 150°C for Vishay parts.

Q: Are the STMicroelectronics STPS41H100CG-TR and STPS41H100CGY-TR interchangeable?

A: Yes, electrically and mechanically. Both parts are identical except for temperature range specification. STPS41H100CGY-TR specifies -40°C to 175°C operating range, while STPS41H100CG-TR specifies maximum 175°C. Both include automotive grade and AEC-Q101 qualification. Selection depends on whether full temperature range documentation is required.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard. Parts bearing this qualification have undergone specific reliability and quality testing for automotive applications. STPS41H100CG-TR and STPS41H100CGY-TR carry this qualification; Vishay parts do not specify this certification.

Q: Can I use an STMicroelectronics part in place of a Vishay part in a non-automotive application?

A: Yes. All substitute parts meet the electrical and mechanical requirements of the VB40100C-M3/8W. Automotive qualification is an enhancement, not a requirement for general applications. Selection should be based on packaging format, supply availability, and forward voltage tolerance.

Q: What is the significance of the forward voltage difference (730 mV vs. 800 mV)?

A: Forward voltage affects power dissipation and thermal performance. Vishay parts specify lower forward voltage (730 mV), resulting in lower power loss. STMicroelectronics parts specify 800 mV. The 70 mV difference is within typical application tolerance but should be evaluated in thermal-sensitive designs. At 20 A, this represents approximately 1.4 W additional dissipation for STMicroelectronics parts.

Q: What packaging formats are available?

A: VB40100C-M3/8W is supplied in Tape & Reel (TR). VB40100C-E3/8W is supplied in Cut Tape (CT) & Digi-Reel®. STPS41H100CG is supplied in Tube. STPS41H100CG-TR and STPS41H100CGY-TR are supplied in Cut Tape (CT) & Digi-Reel®. Packaging selection depends on manufacturing equipment and volume requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
