Overview
The onsemi 1N914A_T50R is a discontinued standard switching diode manufactured in the DO-35 axial through-hole package. It features a maximum DC reverse voltage of 100 V and an average rectified forward current of 200 mA. The device exhibits a typical reverse recovery time of 4 ns, with a maximum forward voltage drop of 1 V at 20 mA. Reverse leakage current is specified as 5 µA at 75 V, and junction capacitance is 4 pF at 0 V and 1 MHz. Operating temperature ranges from -55°C to 175°C.
Feature Summary
- High-speed switching capability characterized by a 4 ns reverse recovery time for efficient signal processing.
- Robust thermal performance supporting operation across a wide junction temperature range up to 175°C.
- Standard silicon construction providing reliable unidirectional current flow in small-signal applications.
Applications
- General-purpose signal switching circuits
- Clamping and protection stages in electronic systems

Procurement Notes
This component is officially marked as obsolete and no longer manufactured by onsemi. Verification of availability requires checking authorized distributors for remaining stock or approved substitute part numbers. Do not assume active production status. Confirm RoHS compliance and specific packaging details via official datasheets before integration into designs requiring long-term supply assurance.
Selection Notes
Designers should evaluate alternative components due to the obsolete status of this part. Consider parameters such as reverse voltage, forward current, and switching speed when selecting replacements. Verify that substitute devices meet the original electrical requirements and physical footprint constraints. Review manufacturer documentation for updated product lifecycle information and recommended cross-reference parts.
Part Context
The 1N914A series belongs to onsemi's legacy portfolio of small-signal switching diodes. These components were widely used in general-purpose electronics for their fast response and reliability. The T50R suffix typically denotes a specific tape-and-reel packaging configuration for automated assembly processes, distinct from bulk packaging variants.
Replacement Considerations
Publicly confirmed similar substitutes include onsemi 1N4447 and 1N914ATR. Microchip Technology offers the 1N4149 as a comparable alternative. Verify pinout compatibility and electrical specifications before substitution.
