1N2055

Single Diodes Overview

The Microchip Technology 1N2055 is a silicon power rectifier diode designed for high-current applications. It features a reverse voltage rating of 100 V and an average forward current capacity of 275 A. The device utilizes a stud mount configuration within the DO-205AB (DO-9) package, with the cathode connected to the case. Constructed with glass-to-metal seal technology, it offers high surge current capability and soft recovery characteristics suitable for demanding power conversion environments.

Single Diodes Procurement Notes

Verify the manufacturer origin, as the 1N2055 designation is used by multiple entities including Microchip, Solid State Inc., and Digitron. Confirm specific suffixes such as PBF for RoHS compliance or HR for high-reliability screening per MIL-PRF-19500 if required. Ensure the package type matches the DO-205AB specification and validate thermal management requirements for the stud mount interface before procurement.

Single Diodes Selection Notes

Select this component when a 100 V reverse voltage and 275 A continuous current are required in a stud-mount form factor. The soft recovery profile makes it appropriate for circuits where reverse recovery charge minimization is beneficial. Consider the thermal resistance of the DO-205AB package and ensure adequate heatsinking for the high forward current application.

Single Diodes Part Context

The 1N2055 belongs to the family of standard recovery silicon power rectifiers. It is historically associated with Motorola and later acquired entities like Microsemi and Microchip Technology. The part serves as a high-power discrete solution for industrial and heavy-duty electronics requiring reliable unidirectional current flow under significant electrical stress.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers using the same JEDEC identifier. Verify that substitute parts from vendors like Digitron or Solid State Inc. match the exact pinout and mechanical dimensions of the DO-205AB package. Check for equivalent soft recovery specifications if switching performance is critical.
