43CTQ100S Description

Short technical summary and product information.

The 43CTQ100S is a Schottky rectifier array from Vishay High Power Products, featuring two 20A Schottky diodes in a common cathode configuration. It is designed for high frequency operation with low forward voltage drop (0.81V max at 20A and 25°C) and fast recovery (<=500ns). The device operates over a junction temperature range of -55°C to 175°C. It is rated for 100V maximum DC reverse voltage and offers high surge capability (850A peak non-repetitive surge current per leg).

 

This diode array is suitable for switching power supplies, freewheeling diodes, and reverse battery protection applications. It is packaged in a TO-263-3 (D2PAK) surface mount package, which is designed for efficient heat dissipation. The guard ring structure enhances ruggedness and long-term reliability. The part is qualified for AEC-Q101 level, making it suitable for automotive applications.

 

The device features low reverse leakage current (1 mA max at 25°C, 11 mA at 125°C) and low junction capacitance (1480 pF max at 5V). The center tap configuration allows for compact PCB layout.
