Engineering Selection Recommendations

MBRB10100 (SMC Diode Solutions):

Primary selection for applications requiring SMC Diode Solutions component qualification
ROHS3 compliant with REACH Affected status
Active product status with established supply chain
Suitable for standard industrial and commercial applications

STPS8H100G-TR (STMicroelectronics):

Qualified substitute for applications permitting STMicroelectronics components
ROHS3 compliant with REACH Unaffected status
Active product status with higher inventory availability (7000 pcs vs. 1892 pcs)
Extended maximum junction temperature rating (175°C vs. 150°C) provides thermal margin in high-temperature environments
Lower forward voltage drop (710 mV @ 8 A vs. 850 mV @ 10 A) reduces power dissipation in current-limited applications

Both parts are functionally equivalent for 100 V Schottky rectifier applications in D2PAK surface mount configurations. Selection between these parts depends on manufacturer qualification requirements, supply chain preferences, and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can STPS8H100G-TR directly replace MBRB10100 in existing designs?

A: Yes. Both parts share identical reverse voltage ratings (100 V), identical D2PAK package configuration, identical surface mount mounting type, and identical fast recovery speed classification (≤ 500 ns). PCB layout and thermal management designs require no modification for direct substitution.

Q: What are the key electrical differences between these parts?

A: The STPS8H100G-TR exhibits lower forward voltage drop (710 mV @ 8 A) compared to the MBRB10100 (850 mV @ 10 A), resulting in reduced power dissipation. The STPS8H100G-TR also features lower reverse leakage current (4.5 µA @ 100 V vs. 1 mA @ 100 V). The STPS8H100G-TR supports higher maximum junction temperature (175°C vs. 150°C).

Q: Are both parts RoHS compliant?

A: Yes. Both MBRB10100 and STPS8H100G-TR are ROHS3 compliant. The MBRB10100 carries REACH Affected status, while the STPS8H100G-TR carries REACH Unaffected status.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling.

Q: Are there packaging differences between these parts?

A: The MBRB10100 is supplied in Tape & Reel (TR) packaging. The STPS8H100G-TR is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both use identical D2PAK component packages suitable for automated surface mount assembly.

Q: Which part should be selected for high-temperature applications?

A: The STPS8H100G-TR is suitable for applications requiring operation up to 175°C junction temperature. The MBRB10100 is rated to 150°C maximum junction temperature. Application thermal analysis determines which part meets operating requirements.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the TO-263-3 D2PAK package configuration with identical lead spacing and tab dimensions. Existing PCB designs require no modification for substitution.
