## **Features** - Ultrafast, soft recovery - Low leakage current - Very low conduction and switching losses - High frequency and/or high pulsed current operation - High reverse voltage capability - High junction temperature capability - ECOPACK2 compliant ## **Applications** - AC-DC converter - DC-DC stage in power supply - DC-AC converter - Solar inverters - EV charging station - Telecom power supply - UPS ## **Description** The high-quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics, and intrinsic ruggedness. These characteristics make it ideal for heavy-duty applications that demand long-term reliability. Such demanding applications include industrial power supplies, motor control, and similar mission-critical systems that require rectification and freewheeling. These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications. ## **Product status link** The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.
