Product details

200 V, 15 A fast recovery rectifier with 36 ns trr

The STTH1502D is a 200 V, 15 A fast recovery epitaxial diode from STMicroelectronics, housed in a through-hole TO-220AC package. Its 36 ns reverse recovery time (trr) places it squarely in the 100-500 kHz PFC boost and hard-switched SMPS secondary rectification class, where stored charge recovery directly dictates switching loss and EMI. Rated junction temperature reaches 175 °C max, which gives thermal headroom in confined enclosures when the diode is bolted to a heatsink. The 10 µA reverse leakage at 200 V is typical for a 200 V planar structure and stays well within the budget for a 15 A output stage.

Conduction loss and thermal budget

Forward voltage is specified at 1.1 V max at 15 A — the conduction loss at full load is 16.5 W before any switching loss is added.

Frequently asked questions
