Overview
The onsemi 1N457A_T50R is a small signal switching diode designed for high conductance and low leakage applications. It features a single configuration housed in a DO-35 through-hole package. Key electrical parameters include a peak reverse voltage of 70 V, a maximum forward current of 200 mA, and a surge current rating of 4 A. The device exhibits a forward voltage of 1 V and a reverse current of 25 nA. It operates within a temperature range of -65 C to +175 C.
Feature Summary
- High conductance performance with low leakage characteristics
- Suitable for general purpose switching applications
- Robust thermal stability across extended temperature ranges
Applications
- General purpose rectification
- Signal switching circuits
- Clamping and protection applications
Procurement Notes
Verify the specific suffix T50R against official datasheets to confirm packaging format, as standard 1N457A parts may differ in bulk or reel specifications. Ensure compatibility with RoHS and REACH requirements for your region. Cross-reference manufacturer part numbers to avoid confusion with similar variants from other vendors.
Selection Notes
Select this component when a small signal diode with 70 V reverse voltage capability is required. Consider the DO-35 package for through-hole mounting constraints. Evaluate the 200 mA forward current limit against circuit demands. Verify operating temperature needs against the -65 C to +175 C range.
Part Context
This component belongs to the 1N457 series of small signal switching diodes. It shares core electrical characteristics with the standard 1N457A but may differ in packaging or manufacturing lot specifics due to the T50R suffix. It serves as a reliable alternative for general purpose diode applications requiring moderate voltage ratings.
Replacement Considerations
Direct substitutes include the standard 1N457A from onsemi or Fairchild. Other manufacturers producing JEDEC registered 1N457A equivalents may also be compatible if pinout and electrical ratings match.
