The 183NQ high current Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection.
The 183NQ series high‑current Schottky rectifier modules are optimized for low reverse leakage at high temperature and are suitable for switching power supplies, converters, free‑wheeling diodes and reverse‑battery protection. The proprietary barrier technology enables reliable operation up to 175 °C junction temperature.
Key specifications include a maximum average forward current of 180 A, reverse voltage ratings of 80 V to 100 V, forward voltage drop as low as 0.75 V at 125 °C, and a junction temperature range of –55 °C to 175 °C. Thermal resistance is 0.30 °C/W (junction‑to‑case) with a typical case resistance of 0.15 °C/W, and the half‑pak package weighs about 25.6 g.
