DSTD5200

Single Diodes Overview

The Littelfuse DSTD5200 is a Schottky Barrier Rectifier housed in a TO-252 (DPAK) single-die package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 5 A at a case temperature of 100°C. The device supports a peak one-cycle non-repetitive surge current of 120 A. Electrical characteristics include a breakdown voltage minimum of 200 V, with forward voltage drops ranging from 0.60 V to 0.90 V depending on test conditions. Reverse current is specified up to 10 mA at 125°C. Thermal resistance from junction to case is 2.4 °C/W, and the operating junction temperature range extends from -55°C to +150°C.
