These characteristics make it ideal Table 1. Device summary for heavy duty applications that demand long term reliability. Symbol Value Such demanding applications include industrial I 15 A F(AV) power supplies, motor control, and similar V 1200 V RRM mission-critical systems that require rectification and freewheeling. These diodes also fit into T 175 C j auxiliary functions such as snubber, bootstrap, V (typ) 1.20 V F and demagnetization applications. t (typ) 53 ns rr The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.
