1N914-T50A

Overview

The onsemi 1N914-T50A is a small signal switching diode housed in a DO-204AH (DO-35) glass package with an Ammo packing method. It features a maximum repetitive reverse voltage of 100 V and supports an average rectified forward current of 200 mA. The device exhibits a typical reverse recovery time of 4.0 ns, ensuring rapid switching performance. Electrical characteristics include a forward voltage of 1.0 V at specified currents and a total capacitance of 4.0 pF at zero bias. Thermal management allows for a power dissipation of 500 mW with a junction-to-ambient thermal resistance of 300 °C/W.

Feature Summary

• High-speed switching capability with a reverse recovery time of 4.0 ns
• Hermetically sealed glass construction for environmental stability
• Capable of handling high non-repetitive peak forward surge currents

Applications

• General purpose signal processing circuits
• Computer logic interface applications
• High-frequency switching operations

Procurement Notes

Verify the specific ordering suffix T50A to confirm the Ammo pack configuration, as other suffixes indicate different packaging methods like bulk or tape and reel. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the document number 98AON13443G for the most current datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when a hermetically sealed axial lead diode is required for robust signal switching. The 100 V breakdown voltage provides adequate margin for standard low-voltage digital logic levels. Consider the 4.0 ns reverse recovery time for applications demanding fast transition speeds without excessive signal distortion or delay.

Part Context

This part belongs to the 1N91x series of small signal diodes manufactured by onsemi. It shares electrical characteristics with the standard 1N914 but differs specifically in its Ammo packaging format. The series includes variants such as 1N914B and 1N916, which offer slight variations in forward voltage and leakage current while maintaining the same physical DO-35 footprint.

Replacement Considerations

The 1N4148 is a widely recognized equivalent within the same family offering identical electrical ratings. Other compatible parts include the 1N914B for potentially lower forward voltage characteristics. Verify that any substitute maintains the DO-35 package dimensions and hermetic sealing properties required for the original design.
