Overview
The Central Semiconductor Corp 1N4454 TR TIN/LEAD is a small signal switching diode designed for high-speed applications. It features a reverse voltage rating of 75V and a forward current capacity of 150mA, with a maximum power dissipation of 500mW. The device exhibits a fast recovery time of 4ns and supports a peak forward surge current of 4A. Packaged in the DO-35 axial leaded format with tin/lead terminal finish, it operates within a temperature range of -65°C to +200°C.
Feature Summary
- High-speed switching capability with rapid recovery characteristics
- Robust thermal performance supporting extended operating temperatures
- Standard axial leaded package configuration for through-hole mounting
Applications
- General purpose signal rectification
- Computer logic interface circuits
- High-frequency switching applications
Procurement Notes
Verify the specific suffix designation to confirm the tin/lead terminal finish and tape-and-reel packaging format. Ensure compliance with RoHS directives if required, as tin/lead variants may differ from lead-free equivalents. Cross-reference datasheets from authorized distributors to confirm availability status and lot traceability before finalizing procurement orders.
Selection Notes
Select this component when axial leaded mounting is preferred over surface mount alternatives. The 75V reverse voltage rating suits low-voltage signal processing tasks. Consider the 150mA continuous current limit for load requirements. The tin/lead finish offers reliable solderability for traditional assembly processes compared to matte tin options.
Part Context
This part belongs to the standard 1N4454 series of silicon planar switching diodes. It serves as a direct replacement for legacy germanium or early silicon switching diodes in retrofitted designs. The series is widely recognized for its reliability in consumer electronics and industrial control systems requiring fast response times.
Replacement Considerations
Direct substitutes include the 1N914 and 1N4148 switching diodes. Verify pinout compatibility and ensure the replacement meets the 75V reverse voltage requirement. Check that the alternative device supports the necessary 4A surge current capability for transient protection scenarios.
