2N5621

Overview

The Microchip Technology 2N5621 is a single fast recovery rectifier designed for through-hole mounting in the A-Package-2 configuration. It features an 800 V reverse voltage rating and supports a continuous forward current of 1 A. The device exhibits a maximum forward voltage drop of 1.6 V at rated current and maintains a low reverse leakage current of 500 nA. Its fast recovery characteristic is defined by a maximum recovery time of 300 ns, enabling efficient operation in high-frequency switching applications. The component operates reliably within a junction temperature range from -65 °C to +175 °C.

Feature Summary

• Fast recovery performance with a 300 ns maximum recovery time for efficient high-frequency switching
• High thermal stability supporting operation up to +175 °C junction temperature
• Robust 800 V reverse voltage capability suitable for demanding power supply environments

Applications

• High-frequency switch-mode power supplies
• Free-wheeling diodes in inductive load circuits

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required mounting style and packaging format. Cross-reference the manufacturer's latest datasheet for any recent product change notifications or pinout updates before finalizing procurement orders.

Selection Notes

Select this component when a fast recovery rectifier with an 800 V blocking voltage is required for through-hole assembly. The 1 A current rating suits moderate power applications where rapid reverse recovery is critical. Verify that the thermal management design accommodates the specified operating temperature range and power dissipation limits under worst-case conditions.

Part Context

This component belongs to the standard rectifier family manufactured by Microchip Technology. It serves as a discrete semiconductor solution for converting alternating current to direct current or protecting circuits from reverse polarity. The device complements other diode products in the manufacturer's portfolio designed for general-purpose and specialized power electronics applications.

Replacement Considerations

Consult official substitution guides for equivalent fast recovery rectifiers with matching voltage and current ratings. Verify pin compatibility and thermal characteristics before replacing the original component with alternative manufacturers' parts.
