Frequently Asked Questions (FAQ)

Q: What makes STPS20H100CT and SDT20B100CT suitable substitutes for VS-MBR20100CTKPBF?

A: Both parts match the critical electrical parameters: 1 Pair Common Cathode Schottky configuration, 100 V DC reverse voltage rating, 10 A average rectified current per diode, and identical TO-220-3 Through Hole package. All three components maintain Fast Recovery speed characteristics and ROHS3 compliance.

Q: Are there differences in forward voltage between the substitutes?

A: STPS20H100CT exhibits 770 mV forward voltage at 10 A, while both VS-MBR20100CTKPBF and SDT20B100CT are rated at 800 mV @ 10 A. This 30 mV difference in STPS20H100CT represents improved efficiency characteristics within acceptable design tolerances for Schottky diode applications.

Q: How do reverse leakage characteristics compare?

A: VS-MBR20100CTKPBF and SDT20B100CT both specify 100 µA reverse leakage @ 100 V. STPS20H100CT provides superior reverse leakage performance at 4.5 µA @ 100 V, representing a 22-fold improvement that may benefit low-leakage circuit requirements.

Q: What is the difference in maximum junction temperature ratings?

A: VS-MBR20100CTKPBF and SDT20B100CT operate across -55°C to 150°C. STPS20H100CT specifies a maximum junction temperature of 175°C, providing 25°C additional thermal margin for high-temperature applications.

Q: Are the packages identical?

A: All three parts use TO-220-3 Through Hole packages. VS-MBR20100CTKPBF and SDT20B100CT specify TO-220-3 as both the Package/Case and Supplier Device Package. STPS20H100CT specifies TO-220 as the Supplier Device Package while maintaining TO-220-3 Package/Case compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. STPS20H100CT is recommended for designs benefiting from lower forward voltage, superior reverse leakage, and higher maximum junction temperature. SDT20B100CT is recommended for designs requiring exact electrical specification matching to the original VS-MBR20100CTKPBF.

Q: Are all substitutes RoHS compliant?

A: Yes. VS-MBR20100CTKPBF, STPS20H100CT, and SDT20B100CT are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity ratings.
