Frequently Asked Questions (FAQ)

Q: Can MBRS130T3G directly replace MBRS130 without PCB modification?

A: Yes. MBRS130T3G is a direct replacement in the same DO-214AA (SMB) package with identical mounting footprint. No PCB modification is required. The forward voltage specification is slightly higher (600 mV vs. 550 mV @ 1A), which is acceptable for most circuit applications.

Q: What is the difference between MBRS130LT3G and MBRS130T3G?

A: MBRS130LT3G provides doubled current capacity (2A vs. 1A) while maintaining 30V reverse voltage in the same SMB package. Both parts are onsemi products with identical package and voltage ratings. Selection depends on application current requirements.

Q: Why does 10BQ030 have lower forward voltage than MBRS130T3G?

A: Forward voltage variation is a normal characteristic of Schottky diodes from different manufacturers and manufacturing processes. 10BQ030 exhibits 420 mV @ 1A compared to MBRS130T3G at 600 mV @ 1A. Lower forward voltage provides improved efficiency and reduced power dissipation in the same 1A, 30V application.

A: Yes, B230-13-F is a suitable substitute with higher current capacity. The part maintains 30V reverse voltage in the same SMB package. Higher current rating provides design margin and is backward compatible with 1A applications. No PCB modification is required.

Q: What is the impact of using PMEG3010EP,115 (SOD-128 package) instead of SMB package?

A: PMEG3010EP,115 requires PCB layout modification due to different package form factor (SOD-128 vs. SMB). The electrical specifications are equivalent (30V, 1A). Forward voltage is superior (360 mV @ 1A). Physical package dimensions and land pattern are different, necessitating PCB redesign.

Q: Is 5818SMJ/TR13 suitable for new designs?

A: 5818SMJ/TR13 is not recommended for new designs requiring RoHS compliance. The part is RoHS non-compliant. Use MBRS130T3G, B130B-13-F, or 10BQ030 for RoHS3 compliant alternatives with equivalent electrical specifications.

Q: What is the operating temperature difference between MBRS130 and substitute parts?

A: MBRS130 operates to 125°C maximum junction temperature. Most substitute parts (10BQ030, B130B-13-F, B230-13-F, B230Q-13-F, BAT165E6327HTSA1, PMEG3010EP,115) extend to 150°C maximum junction temperature, providing improved thermal margin for high-temperature applications.
