Overview
The onsemi 1N914A is a small signal switching diode housed in the DO-204AH (DO-35) axial lead package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current rating of 200 mA. The device exhibits a typical reverse recovery time of 4.0 ns, with a forward voltage of 1.0 V at 20 mA and a reverse leakage current of 5.0 µA at 75 V. Operating junction temperatures range from -55°C to +175°C.
Feature Summary
- High-speed switching capability characterized by a 4.0 ns reverse recovery time.
- Robust thermal performance supporting operation up to a 175°C junction temperature.
- Hermetically sealed glass construction within the DO-35 axial lead package.
Applications
- General-purpose high-speed switching circuits
- Clamping and protection applications
- Pulse generation and shaping networks
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing method. Standard bulk packaging corresponds to the base part number, while tape and reel options require distinct suffixes such as TR or ATR. Confirm RoHS compliance status through the manufacturer's latest environmental declarations prior to integration.
Selection Notes
Select this component for designs requiring fast switching speeds within a standard axial lead form factor. Ensure the circuit operates within the 100 V peak reverse voltage limit and the 200 mA average forward current threshold. Consider the 4.0 ns recovery time for high-frequency pulse applications where rapid transition is critical.
Part Context
This device belongs to the 1N91x series of small signal diodes manufactured by onsemi. It shares electrical characteristics with related variants like the 1N914 and 1N916, differentiated primarily by specific breakdown voltage tolerances and marking codes. The product line utilizes established silicon planar technology for reliable general-purpose performance.
Replacement Considerations
The 1N914 serves as a direct functional equivalent within the same series. Other compatible alternatives include the 1N4148 and 1N4448, which share similar switching speeds and package dimensions but may differ slightly in surge current ratings.
FAQ
