The 151CMQ045 is a Schottky rectifier module manufactured by Vishay Dale, featuring a common cathode configuration with two diodes in one package. It is designed for high-current applications requiring low forward voltage drop and high efficiency. The device has a maximum DC reverse voltage rating of 45V and an average forward current of 150A per leg under specified conditions (50% duty cycle, Tc=104°C, rectangular waveform). Forward voltage is typically 0.71V at 75A and 25°C, and 0.92V at 150A and 25°C. Reverse leakage current is 5mA at 25°C and 45mA at 125°C, both at rated voltage. The module offers a non-repetitive peak surge current of 9200A per leg (5µs pulse) and 1200A per leg (10ms pulse). Avalanche energy rating is 101mJ per leg. The device operates over a junction temperature range of -55°C to 175°C, with a thermal resistance junction-to-case of 1.0°C/W per leg and 0.50°C/W per package. The package is a D-60 (modified JEDEC TO-249AA) with an isolated heatsink for chassis mounting. Termination style is PC board mounting with multiple leads per terminal. Typical applications include switching power supplies, converters, freewheeling diodes, and reverse battery protection.
