Overview
The onsemi 1N4446_T50R is a small signal rectifier diode housed in a DO-35 glass package. It features a maximum repetitive reverse voltage of 100 V and an average forward current rating of 200 mA. The device exhibits a low forward voltage of 1.0 V at 20 mA and a total capacitance of 4 pF at 0 V bias. Key electrical characteristics include a reverse recovery time of 4 ns and a non-repetitive peak surge current capability of 1.0 A for one-second pulses.
Feature Summary
- High-speed switching performance with a reverse recovery time of 4 ns
- Low junction-to-ambient thermal resistance for efficient heat dissipation
- Hermetically sealed glass construction for environmental protection
Applications
- General-purpose rectification in electronic circuits
- Clamping and protection applications
- Signal processing and detection circuits
Procurement Notes
Verify the specific T50R suffix against official documentation to confirm tape-and-reel packaging specifications. Ensure the component meets required operating temperature ranges, as ratings are based on a maximum junction temperature of 200 degrees C. Confirm compliance with relevant industry standards before integration into final designs.
Selection Notes
Select this component for applications requiring fast switching speeds and low capacitance. The 100 V reverse voltage rating suits general-purpose low-voltage rectification tasks. Consider the 200 mA average current limit when designing power stages. The DO-35 package is suitable for through-hole mounting configurations.
Part Context
This part belongs to the standard 1N444x series of small signal diodes. These devices are widely used in consumer electronics and industrial equipment for signal processing. The 1N4446 variant specifically offers a 100 V breakdown voltage, distinguishing it from lower-voltage counterparts in the same family.
Replacement Considerations
Direct replacements include other 1N4446 variants from different manufacturers, provided they meet the 100 V reverse voltage and 200 mA current requirements. Verify pinout compatibility and package dimensions (DO-35) to ensure mechanical fit.
