1N4246

Single Diodes Overview

The Microchip Technology 1N4246 is a single-element rectifier diode designed for through-hole mounting. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a maximum non-repetitive peak forward surge current of 25 A and a maximum forward voltage of 1.2 V. It operates within a junction temperature range up to 160 °C.

Single Diodes Feature Summary

• Provides unidirectional current conduction for AC-to-DC conversion applications
• Engineered with glass passivation for stable electrical performance under thermal stress
• Constructed as a single-element unit for straightforward circuit integration

Single Diodes Applications

• General-purpose power supply rectification
• High-voltage DC blocking circuits
• Industrial control system protection

Single Diodes Procurement Notes

Verify the specific manufacturer designation, as Allied Electronic & Semiconductor Technology Inc also lists this part number. Confirm that the required 400V rating aligns with your circuit design rather than assuming higher ratings from similar series members like the 1N4247. Ensure the through-hole package style matches your board layout requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 400V reverse voltage rating is sufficient for the application. Consider the 1A current limit for load requirements. Evaluate the 160 °C junction temperature limit against ambient conditions. Compare against the 1N4247 if a 600V rating is necessary instead.

Single Diodes Part Context

This component belongs to the standard recovery rectifier diode category. It shares the axial leaded form factor common in legacy electronic designs. The 1N4246 serves as a lower voltage alternative to higher-rated counterparts within the same product family, offering a balance between voltage handling and forward conduction characteristics.
