1N1201B

Single Diodes Overview

The Microchip Technology 1N1201B is a standard recovery rectifier diode housed in a DO-4 package. It features a glass passivated die with glass-to-metal seal construction, ensuring robust performance under high thermal stress. The device supports a repetitive peak reverse voltage of 150 V and a forward current of 12 A. Key electrical parameters include a maximum forward voltage of 1.2 V at the rated current and a forward surge current rating of 250 A. The component operates within a maximum temperature range of 200 °C.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Low forward voltage characteristic for efficiency
• High surge current capability of 250 A
• Robust glass-to-metal seal design

Single Diodes Applications

• General purpose rectification in power supplies
• High-temperature electronic circuits
• Industrial control systems requiring rugged components

Single Diodes Procurement Notes

Verify the specific manufacturer source, as listings may vary between Microchip Technology and other distributors. Confirm the package type is DO-4 and check for RoHS compliance status, as some sources indicate non-RoHS packaging options. Ensure the ordering suffix matches the required lead time and stock availability from authorized channels.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 150 V reverse voltage and 12 A continuous forward current is required. The DO-4 package and glass-to-metal seal make it suitable for applications demanding high thermal stability up to 200 °C. Consider the 250 A surge rating for transient protection needs.

Single Diodes Part Context

The 1N1201B belongs to the family of standard rectifier diodes produced by Microchip Technology. It utilizes a glass passivated die to improve junction stability and longevity compared to non-passivated alternatives. The DO-4 axial leaded package provides mechanical strength and ease of mounting on PCBs or through-hole assemblies.

Single Diodes Replacement Considerations

Check for direct substitutes such as the 1N3801B from New Jersey Semiconductor Products Inc, which shares similar electrical characteristics. Verify pinout compatibility and thermal ratings before substitution.
