What this TrenchStop IGBT does on the board
The IGU04N60TAKMA1: On-state voltage is 2.05 V at 15 V gate drive and 4 A, which is typical for a 600 V trench IGBT at this current density. Switching energy of 61 µJ (on) and 84 µJ (off) under the test condition of 400 V, 4 A, 47 Ω gate resistor lets the designer estimate total loss at the target switching frequency. The 175 °C maximum junction temperature provides extra thermal margin for enclosed or high-ambient installations.
Package and mounting — TO-251-3 (IPak)
The PG-TO251-3 package is a compact through-hole option with short leads, smaller than a TO-220 but still hand-solderable. It saves board area in space-constrained designs, though the lack of a mounting hole limits heatsink attachment to clip-on or adhesive-bonded sinks.
