1N2256

Single Diodes Overview

The Microchip Technology 1N2256 is a silicon rectifier diode housed in the DO-4 (DO-203AA) stud mount package. It features a glass passivated die and glass-to-metal seal construction, providing robust performance in high-power applications. The device supports a maximum repetitive peak reverse voltage of 500 V and an average rectified forward current of 22 A. It exhibits a low forward voltage characteristic and handles a surge rating of up to 200 A. The junction temperature range spans from -65°C to 200°C, ensuring reliability under extreme thermal conditions.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm package variations and compliance status. Ensure the component matches the required voltage and current ratings for the target application. Confirm lead times with authorized distributors as manufacturing schedules may vary. Validate that the glass-to-metal seal integrity meets environmental requirements for the intended deployment.

Single Diodes Selection Notes

Select this component when a stud-mount rectifier with high thermal capacity is required. The 500 V reverse voltage rating suits medium-voltage applications. Consider the 22 A continuous current limit for load matching. The wide operating temperature range allows use in harsh environments where standard packages might fail due to thermal stress.

Single Diodes Part Context

This part belongs to the standard rectifier diode family manufactured by Microchip Technology. It utilizes silicon technology and is designed for general-purpose power rectification. The DO-4 package provides a mechanical interface suitable for direct mounting to heatsinks or chassis structures for effective thermal management in industrial equipment.

Single Diodes Replacement Considerations

Aftermarket equivalents exist, such as those listed under item AW0534 by Aftermarket IR Industrial Controls. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same stud mount style and voltage/current ratings.
