1N4148_L99Z

Single Diodes Overview

The onsemi 1N4148_L99Z is a small signal switching diode manufactured 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 fast reverse recovery time of 4 ns, making it suitable for high-speed applications. Electrical characteristics include a forward voltage of 1.0 V at 10 mA and a total capacitance of 4.0 pF at 0 V reverse bias. The component operates within a junction temperature range of -55°C to +175°C.

Single Diodes Feature Summary

• Fast switching capability with a 4 ns reverse recovery time for efficient signal processing
• High thermal stability supporting operation up to a 175°C junction temperature
• Robust surge handling with a 4 A non-repetitive peak forward surge current rating

Single Diodes Applications

• High-frequency signal switching circuits
• Clamping and protection stages in electronic systems

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packing method and marking details. Confirm RoHS compliance status and availability through authorized channels. Ensure the selected variant matches the required package dimensions and lead configuration for your PCB layout.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with a DO-35 package is required. Consider the 100 V reverse voltage limit and 200 mA continuous current rating during circuit design. Evaluate the 4 ns recovery time against your application's frequency requirements to ensure adequate performance margins.

Single Diodes Part Context
