CDBMH340-HF

Overview

The CDBMH340-HF is a Schottky Barrier Rectifier from the Comchip Technology CDBMH Series, designed for low-profile surface-mounted applications to optimize board space. It utilizes a silicon epitaxial planar chip with a metal-silicon junction in an SOD-123T package. Key electrical parameters include a maximum repetitive peak reverse voltage of 40 V, a continuous reverse voltage of 40 V, and a maximum forward rectified current of 3.0 A. The device exhibits a maximum forward voltage of 0.70 V at 3.0 A and a maximum reverse current of 80 mA at rated voltage and 25°C. It supports a maximum non-repetitive forward surge current of 80 A under JEDEC conditions.

Feature Summary

Batch process design providing excellent power dissipation for improved reverse leakage current and thermal resistance.
Ultra high-speed switching capability suitable for efficient power conversion.
Guarding function for overvoltage protection within the circuit.

Applications

Low profile surface mounted applications requiring optimized board space.
High efficiency power supply circuits.
Overvoltage protection guarding.

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm pinout orientation and marking codes. Ensure compatibility with the SOD-123T footprint dimensions provided in the mechanical data sheet. Confirm environmental compliance status such as lead-free and halogen-free specifications prior to integration into final assemblies.

Selection Notes

Select this component when a 40 V reverse voltage rating and 3.0 A continuous current capacity are required in a compact surface-mount form factor. Consider the 0.70 V forward voltage drop for power loss calculations at full load. Evaluate the thermal resistance characteristics if operating near the upper limits of the specified temperature range.

Part Context

This component belongs to the CDBMH Series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology. The series encompasses various voltage ratings ranging from 20 V to 100 V, all sharing similar physical dimensions and performance characteristics tailored for miniaturized electronic designs.
