Product details

Automotive qualification and the under-hood decision

For a BOM destined for a 48 V mild-hybrid DC-DC converter or an engine-cooling fan drive, the AEC-Q101 stamp is the baseline — commercial-grade parts do not survive the thermal shock profile.

Gate charge and drive compatibility

With a maximum gate charge of 3.4 nC at 10 V, the STD3N95K5AG presents a light load to the gate driver. The low input capacitance of 105 pF at 100 V drain-source further reduces the switching loss contribution from the Miller plateau.

Frequently asked questions

What does the Automotive grade on STD3N95K5AG mean for my design?

The Automotive grade together with AEC-Q101 qualification means this MOSFET has been screened for extended temperature cycling, high-temperature reverse bias, and humidity stress — requirements for under-hood and chassis-domain automotive electronics.
