80SQ05

Overview

The Diotec Semiconductor 80SQ05 is a Schottky Barrier Rectifier Diode designed for high-efficiency power conversion. It features an average forward current (IFAV) of 8 A and a peak forward surge current (IFSM) reaching up to 180 A at 60 Hz. The device exhibits a low forward voltage drop, specified as less than 0.50 V at 5 A and less than 0.55 V at 8 A. It supports a junction temperature range from -50°C to +150°C in DC operation and offers thermal resistance values of 15 K/W to ambient and 6 K/W to leads.

Feature Summary

• Schottky barrier construction enables fast switching speeds and minimal reverse recovery charge.
• Low forward voltage characteristics reduce conduction losses and improve overall system efficiency.
• Robust surge current handling capability ensures reliability during transient overload conditions.

Applications

• DC-DC converters
• Free-wheeling diodes in inductive load circuits
• Polarity protection circuits

Procurement Notes

Verify the specific package type and marking code against the official datasheet before ordering. Confirm compliance with RoHS and halogen-free requirements if mandated by your design specifications. Ensure that thermal management strategies align with the provided junction-to-ambient thermal resistance data for your intended operating environment.

Selection Notes

Select this component when high efficiency and low forward voltage are critical for power loss reduction. Evaluate the thermal dissipation requirements based on the 8 A continuous current rating and the specific ambient temperature conditions of the application. Consider the surge current ratings to ensure adequate margin for startup or fault conditions.
