Overview
The Microchip Technology 1N4938/TR is a small signal switching diode designed for general-purpose applications. It features a peak reverse voltage of 175 V and supports a maximum forward current of 100 mA with a power dissipation rating of 500 mW. The device operates within a temperature range of -65°C to +175°C and exhibits a fast recovery time of 50 ns. Packaged in the DO-213AA-2 (SOD-323) surface-mount format, it offers low leakage current of 100 nA and a maximum capacitance of 5 pF.
Feature Summary
- High-temperature operation capability up to 175°C
- Fast switching performance with 50 ns recovery time
- Low leakage current for efficient signal handling
Applications
- General-purpose rectification circuits
- Signal processing and computer diodes
- High-temperature electronic environments
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required thermal and electrical ratings for the target application environment. Cross-reference datasheet parameters such as peak reverse voltage and forward current to validate suitability for circuit design constraints.
Selection Notes
Select this component when high-temperature stability and fast switching are required in a compact surface-mount package. The 175V rating provides robustness against voltage transients, while the 100mA current capacity suits low-power signal applications. Consider the DO-213AA-2 footprint for PCB layout compatibility.
Part Context
This part belongs to the standard small-signal switching diode family from Microchip Technology. It serves as a reliable solution for basic rectification and signal clamping tasks where moderate speed and high-temperature resilience are prioritized over high-current handling capabilities.
Replacement Considerations
Consult official substitution guides for compatible equivalents. Verify pinout compatibility and ensure that alternative components meet or exceed the 175V reverse voltage and 100mA forward current specifications.
