Overview
The 1N4454-TAP is a small-signal silicon epitaxial planar diode manufactured by Vishay Semiconductors. It features a DO-35 glass case and is designed for fast switching applications. Key electrical parameters include a maximum average rectified current of 150 mA, a reverse voltage rating of 75 V, and a peak reverse voltage of 100 V. The device exhibits a maximum forward voltage drop of 1.0 V at 10 mA and a reverse recovery time of 4 ns. Maximum power dissipation is 500 mW with a thermal resistance of 350 °C/W. Operating junction temperature ranges up to 175 °C.
Feature Summary
- Silicon epitaxial planar construction for reliable performance
- Fast switching capability with minimal reverse recovery time
- Glass passivated junction for environmental stability
Applications
- High-speed switching circuits
- General-purpose signal rectification
- Clamping and protection in low-power electronics
Procurement Notes
Verify the specific suffix -TAP indicates tape-and-reel packaging when ordering. Confirm RoHS compliance and halogen-free status against current Vishay documentation. Ensure the DO-35 package dimensions match your PCB footprint requirements. Check for any automotive qualification status if applicable to your design environment.
Selection Notes
Select this component for applications requiring fast recovery times under 5 ns. Consider the 150 mA current limit for load requirements. Evaluate the 75 V reverse voltage rating against circuit peak voltages. The DO-35 through-hole package suits manual or standard automated assembly processes.
Part Context
This diode belongs to the 1N445x series of small-signal switching diodes. It shares similar characteristics with other fast-switching variants but offers specific voltage and current ratings suited for general-purpose high-speed logic and signal processing tasks within consumer and industrial electronics.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the DO-35 package and 150 mA current rating. Verify equivalent reverse recovery time and voltage specifications before integration.
