The 82CNQ030A is a center tap Schottky rectifier module from IRF company, which has very low forward voltage drop with moderate leakage current. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature. Typical applications include switching power supplies, converters, free-wheeling diodes, and reverse battery protection.
The 82CNQ030A is a center‑tap Schottky rectifier module designed for low forward voltage drop and moderate leakage, suitable for switching power supplies, converters, free‑wheeling diodes and reverse battery protection. It is packaged in a D‑61 low‑profile case and rated for up to 150 °C junction temperature.
Key specifications include an 80 A maximum forward current, a typical forward voltage drop of 0.47 V at 40 A (0.55 V at 80 A), a reverse leakage current of 5 mA, junction capacitance of 3700 pF, and thermal resistance of 0.85 °C·W to case. The device operates from –85 °C to +150 °C and weighs approximately 7.8 g.
