42CTQ030S Description

Short technical summary and product information.

The 42CTQ030S is a dual common cathode Schottky rectifier array from Vishay High Power Products. It features two 20 A Schottky diodes in a single D2PAK package, providing a total forward current of 40 A. The device is rated for a maximum reverse voltage of 30 V and offers very low forward voltage drop, typically 0.48 V at 20 A and 25°C. It is designed for high frequency operation and includes guard ring protection for enhanced ruggedness and long-term reliability.

 

The 42CTQ030S is qualified to Q101 level, making it suitable for automotive and industrial applications. It can handle high surge currents up to 1100 A peak (5 µs pulse) and has an operating junction temperature range of -55°C to 150°C. The device is surface mounted in a D2PAK (TO-263AB) package, which is ideal for space-constrained designs.

 

Typical applications include switching power supplies, freewheeling diodes, and reverse battery protection. The low forward voltage drop and fast switching characteristics make it efficient for high-frequency power conversion circuits.
