1N5618

Overview

The Microchip Technology 1N5618 is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage rating of 600 V. The device utilizes a silicon planar junction construction with a glass-passivated cathode to ensure stability under harsh conditions. Key electrical parameters include a maximum non-repetitive peak forward surge current of 30 A, a maximum DC reverse leakage current of 500 mA at rated voltage, and a typical forward voltage drop of 800 mV. The component supports an operating junction temperature range from -65 °C to +200 °C.

Feature Summary

• Glass-passivated junction structure provides high reliability and environmental stability
• High thermal performance capability with extended operating temperature range up to 200 °C
• Standard recovery characteristics suitable for general-purpose rectification tasks

Applications

• Power supply rectification circuits
• General-purpose freewheeling diode applications
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix code on the datasheet or purchase order, as variants such as JAN1N5618 may differ in qualification level or packaging. Confirm RoHS compliance status, as military-grade versions often lack lead-free certification. Ensure the axial lead package matches the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a robust 600 V, 1 A rectifier is required for standard frequency operations. The wide junction temperature range makes it suitable for high-thermal environments where standard commercial diodes might fail. Consider the 500 mA reverse leakage specification when designing low-power standby modes to minimize quiescent current consumption.
