• Technology: Schottky (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 100 V (mandatory match)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max): Substitute parts must not exceed the maximum forward voltage specification of the main part at their respective rated currents
• Current - Reverse Leakage @ Vr: Substitute parts must maintain leakage specifications within acceptable operating ranges
• Operating Temperature - Junction: Substitute parts must support the minimum operating range of -55°C to 150°C

The identified substitute parts MBRB20100CT-13 and STPS10H100CG-TR satisfy all primary substitution criteria and maintain electrical compatibility within the defined parameter boundaries.

Engineering Selection Recommendations

STB40100C (SMC Diode Solutions) The main part is Active in product status with RoHS3 compliance and unlimited moisture sensitivity. This component is suitable for general industrial applications requiring a 100 V Schottky diode array in D2PAK surface mount packaging. Current inventory of 1700 pieces is available.

MBRB20100CT-13 (Diodes Incorporated) This substitute part is Active in product status with RoHS3 compliance and carries AEC-Q101 automotive qualification. The MBRB20100CT-13 is rated for 10 A average rectified current per diode and supports an extended operating temperature range to 175°C. This part is suitable for automotive applications and high-current requirements. Current inventory of 33,400 pieces is available. The forward voltage specification of 840 mV @ 10 A is higher than the main part at its rated current, but remains within acceptable operating parameters for this device category.

STPS10H100CG-TR (STMicroelectronics) This substitute part is Active in product status with RoHS3 compliance. The STPS10H100CG-TR is rated for 5 A average rectified current per diode with a maximum junction temperature of 175°C. This part exhibits superior reverse leakage characteristics at 3.5 µA @ 100 V and a forward voltage of 730 mV @ 5 A, which is lower than the main part. Current inventory of 4,960 pieces is available. Packaging is provided in Cut Tape (CT) & Digi-Reel® format rather than standard Tape & Reel.

All three parts maintain identical electrical configuration, voltage rating, package form factor, and compliance status. Selection between these parts depends on current requirements, temperature operating range, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can the MBRB20100CT-13 be used as a direct replacement for the STB40100C?

A: Yes. The MBRB20100CT-13 maintains identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, D2PAK surface mount package, and RoHS3 compliance. The part is electrically and mechanically compatible. The MBRB20100CT-13 provides higher current capability (10 A) and extended temperature range (-55°C to 175°C), making it suitable for applications requiring these enhanced specifications.

Q: Can the STPS10H100CG-TR be used as a direct replacement for the STB40100C?

A: Yes. The STPS10H100CG-TR maintains identical diode configuration, Schottky technology, 100 V reverse voltage rating, D2PAK surface mount package, and RoHS3 compliance. The part is electrically and mechanically compatible. The STPS10H100CG-TR is rated for 5 A average rectified current and features lower reverse leakage (3.5 µA @ 100 V) and lower forward voltage (730 mV @ 5 A). Packaging is provided in Cut Tape (CT) & Digi-Reel® format.

Q: What are the key differences between the three parts?

A: All three parts share the same 100 V Schottky diode array configuration in D2PAK packaging. The primary differences are: (1) Current rating: STB40100C is not specified, MBRB20100CT-13 is 10 A, STPS10H100CG-TR is 5 A; (2) Temperature range: STB40100C operates to 150°C, both substitutes operate to 175°C; (3) Reverse leakage: STB40100C is 1 mA @ 100 V, MBRB20100CT-13 is 100 µA @ 100 V, STPS10H100CG-TR is 3.5 µA @ 100 V; (4) Forward voltage: varies by rated current; (5) Packaging format: STB40100C and MBRB20100CT-13 are Tape & Reel, STPS10H100CG-TR is Cut Tape & Digi-Reel®; (6) Automotive qualification: MBRB20100CT-13 carries AEC-Q101 qualification.

Q: Are all three parts RoHS3 compliant?

A: Yes. The STB40100C, MBRB20100CT-13, and STPS10H100CG-TR are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute part should be selected for automotive applications?

A: The MBRB20100CT-13 is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive applications. This part also provides the highest current rating (10 A) and extended temperature range to 175°C.

Q: Which substitute part has the lowest reverse leakage?

A: The STPS10H100CG-TR exhibits the lowest reverse leakage at 3.5 µA @ 100 V, compared to 100 µA @ 100 V for the MBRB20100CT-13 and 1 mA @ 100 V for the STB40100C.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects handling, storage, and assembly processes but does not affect electrical performance. Selection between packaging formats depends on manufacturing equipment compatibility and supply chain requirements.

Q: What is the significance of the D2PAK package designation?

A: D2PAK is a surface mount package with 2 leads plus a tab for thermal management. All three parts use the identical TO-263-3 D2PAK (2 Leads + Tab), TO-263AB package, ensuring mechanical and thermal compatibility in PCB layouts designed for this form factor.
