S8CMHQ-13

Single Diodes Overview

The S8CMHQ-13 is an 8.0A surface-mount glass passivated rectifier in the SMC package, designed for high current capability and low forward voltage drop. It features a guard ring for transient protection and high surge capacity. Key electrical parameters include a peak repetitive reverse voltage of 1,000V, an average rectified output current of 8.0A at +75°C, and a maximum forward voltage of 0.985V at 8.0A. The device supports a non-repetitive peak forward surge current of 450A (1.0ms) and operates within a temperature range of -65°C to +150°C.

Single Diodes Procurement Notes

Verify that the ordering suffix '-13' corresponds to the specified tape and reel packaging quantity of 3,000 units per carrier. Confirm compliance with RoHS directives and halogen-free requirements by checking the manufacturer's quality documentation. Ensure the component meets AEC-Q101 qualification standards if automotive application change control is required.

Single Diodes Selection Notes

Select this component when a high-current surface-mount rectifier with robust transient protection is needed. The SMC package provides efficient thermal dissipation for applications requiring 8.0A continuous current. Verify that the 1,000V reverse voltage rating aligns with the circuit's peak repetitive reverse voltage requirements.
