The through-hole mounting suits point-to-point wiring and high-vibration environments where a soldered SMT part might crack the joint.
Gate drive and switching — 120 nC total gate charge
A gate driver sourcing 1 A peak can turn the FET on in about 120 ns — fast enough for a 50–100 kHz hard-switched converter.
Temperature range and application environment
This makes the part suitable for avionics power supplies, downhole instrumentation, satellite payloads, and outdoor industrial drives where ambient temperatures can exceed 85°C. The 175°C maximum junction allows a higher thermal headroom than a 150°C-rated part, which translates into a smaller heatsink for the same power dissipation.
The TO-220 Full Pack package is a mature, widely stocked form factor, so lead times are generally stable for production quantities.
