The 83CNQ.A series is a Schottky rectifier module product launched by IRF company. This product has excellent low reverse leakage characteristics and can operate reliably under high temperature conditions. It is suitable for switching power supplies, converters, free-wheeling diodes and reverse battery protection.
The 83CNQ...A series is a center‑tap Schottky rectifier module optimized for low reverse leakage at high temperature, suitable for switching power supplies, converters, free‑wheel diodes, and reverse battery protection. The series uses a new D‑61 package with high‑purity epoxy encapsulation for mechanical strength and moisture resistance.
Key specifications include an 80 A maximum forward current, reverse voltage ratings up to 100 V, low forward voltage drop (0.81 V at 80 A, 25 °C), and a junction temperature range of –55 °C to 175 °C. Thermal resistance values, package dimensions, and SPICE models are also provided.
