Single IGBTs Procurement Notes

Verify the specific suffix 'RLD' against the official onsemi datasheet to confirm the exact pinout and packaging configuration. Ensure that the procurement channel provides valid AEC-Q101 certification documentation. Cross-reference the part number with the manufacturer's latest release notes to confirm availability and any potential design changes or obsolescence warnings prior to finalizing orders.

Single IGBTs Selection Notes

Select this component when designing systems requiring high voltage isolation and low on-state losses in automotive environments. The 1200V rating provides sufficient headroom for typical EV bus voltages. Consider the TO-247-3 package for its thermal performance and ease of integration into existing heatsink structures. Evaluate the short-circuit withstand time requirements of the application against the device's specified limits to ensure adequate system protection.

Single IGBTs Part Context

This IGBT belongs to onsemi’s AFGH series, which utilizes advanced Field Stop Trench technology to optimize the trade-off between conduction and switching losses. The series is specifically engineered for automotive applications, meeting stringent quality and reliability standards.
