Product details
Overview
MBR1535CTHE3/45 from Vishay General Semiconductor is a dual common-cathode Schottky rectifier optimized for high-frequency switching power supplies, delivering 7.5 A average forward current per diode, 35 V maximum repetitive peak reverse voltage, and 0.57 V forward voltage at 7.5 A and 25 °C. It features guardring overvoltage protection and operates up to 150 °C junction temperature.
For engineers reviewing the MBR1535CTHE3/45 datasheet, MBR1535CTHE3/45 pinout, MBR1535CTHE3/45 application, or MBR1535CTHE3/45 equivalent, key selection criteria include low VF for efficiency in DC-DC converters, high IFSM (150 A) for surge robustness, TO-220AB package thermal performance, and RoHS/WEEE compliance for industrial and consumer designs.
Technical Context
This dual-diode Schottky rectifier integrates two independent anodes sharing one cathode terminal, enabling compact freewheeling or synchronous rectification in half-bridge or dual-output topologies. Its low VF and fast recovery support high-efficiency operation in 100 kHz–1 MHz SMPS designs.
The device uses planar Schottky barrier construction with guardring edge termination to suppress avalanche-induced failure under transient overvoltage. Thermal resistance RθJC is 3.0 °C/W per diode, and it meets J-STD-020 MSL Level 1 with 245 °C reflow peak tolerance.
Key Specifications
