Overview
The BAV21_NT50A is a small signal switching diode manufactured by onsemi, housed in a DO-35 through-hole package. It features a peak reverse voltage of 250 V and a maximum forward current of 200 mA. The device supports a surge current of 4 A with a reverse recovery time of 50 ns. Operating parameters include a forward voltage of 1.25 V and a reverse current of 100 nA. The component functions within a temperature range of -65 C to +175 C.
Feature Summary
- High voltage capability for general-purpose switching applications
- Fast recovery characteristics suitable for signal processing
- Robust thermal performance across extended temperature ranges
Applications
- General purpose high voltage switching circuits
- Signal processing applications requiring fast recovery
- Protection circuits in electronic systems
Procurement Notes
Verify the obsolete status of this component before design finalization. Confirm availability through authorized distributors or secondary markets. Ensure the DO-35 package matches your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the 200 mA current rating meets your circuit load demands.
Selection Notes
Select this component when a high reverse voltage rating of 250 V is required in a standard through-hole package. Consider the 50 ns recovery time for speed-sensitive signal paths. Evaluate the 200 mA continuous current limit against your application's peak loads. The wide operating temperature range supports harsh environment deployments.
Part Context
This part belongs to the BAV21 series of small signal switching diodes from onsemi. It is designed for general usage where high voltage isolation and moderate speed are necessary. The DO-35 package provides a traditional through-hole mounting option for legacy or robust circuit designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Verify compatibility with generic DO-35 250V switching diodes if direct substitutes are needed.
