30CTQ035S Description

Short technical summary and product information.

The 30CTQ035S is a Schottky rectifier diode from SMC Diode Solutions, designed for high efficiency power conversion. It offers a peak repetitive reverse voltage of 35 V and an average rectified forward current of 15 A per leg (30 A total). The device features a low forward voltage drop of typically 0.55 V at 15 A and 25°C, improving to 0.48 V at 125°C, which reduces power loss in high-current applications.

The Schottky technology enables fast switching with minimal reverse recovery time, suitable for high-frequency operation. It is configured as a pair of common cathode diodes, housed in a TO-263-3 (D²Pak) surface mount package with a 100% pure tin finish. The junction temperature range is -55°C to 175°C, and the typical junction-to-case thermal resistance is 3.25 °C/W.

Common applications include switching power supplies, DC-DC converters, free-wheeling diodes, and reverse battery protection circuits. The guard ring design enhances ruggedness and long-term reliability. This device is lead-free and RoHS3 compliant per the datasheet.
