Overview
The Microchip Technology 1N4938UR-1 is a small signal switching diode designed for surface mount applications. It features a peak reverse voltage of 175 V and an average forward current rating of 100 mA. The device operates within a temperature range of -65°C to +175°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a forward voltage of 1 V at 100 mA, and a reverse recovery time of 50 ns. It is housed in the DO-213AA-2 package.
Feature Summary
- Provides high-temperature operation capability up to 175°C junction temperature
- Offers fast switching performance with a 50 ns reverse recovery time
- Designed for surface mount integration using the DO-213AA-2 package
Applications
- Signal or computer diode circuits
- General purpose switching applications
- High-temperature electronic environments
Procurement Notes
Verify compliance requirements prior to procurement as this component does not meet RoHS standards. Confirm that the specified DO-213AA-2 surface mount package aligns with the target PCB layout constraints. Ensure design margins accommodate the 175°C maximum operating temperature and 100 mA current limits for reliable long-term functionality.
Selection Notes
Select this component when a surface mount switching diode with extended thermal tolerance is required. The 175 V reverse voltage rating suits moderate voltage blocking needs. Consider the 50 ns recovery speed for general signal processing tasks. Verify that the non-RoHS status meets regulatory requirements for the intended deployment region.
Part Context
This part belongs to the Microchip Technology small signal switching diode portfolio. It serves as a surface mount alternative to through-hole variants like the 1N4938-1. The device supports industrial and commercial electronics requiring robust rectification and switching capabilities under elevated thermal conditions.
Replacement Considerations
Cross-reference with other 1N4938 series components from different manufacturers if pin-compatible replacements are needed. Verify that substitute parts match the 175 V reverse voltage and 100 mA forward current specifications.
