Overview
The 1N4454/TR is a signal or computer diode manufactured by Microchip Technology. It features a round-end axial leaded package and is supplied in tape and reel format. The device is rated for a maximum repetitive peak reverse voltage of 75V and an average forward rectified current of 200mA. Key electrical characteristics include a maximum reverse leakage current of 25nA at the rated voltage and a typical reverse recovery time of 4ns. The component operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Designed for high-speed switching applications with fast reverse recovery characteristics
- Constructed with metallurgically bonded double plug technology for reliability
- Available in standard axial through-hole packaging suitable for automated assembly
Applications
- High-speed switching circuits
- Computer logic interface diodes
- General purpose signal rectification
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm the tape and reel packaging configuration. Ensure the part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the manufacturer's datasheet for any updates on environmental compliance or pinout definitions before finalizing procurement orders.
Selection Notes
Select this component when a general-purpose silicon switching diode with low capacitance and fast recovery is required. Compare the 75V reverse voltage rating against the circuit's peak inverse voltage requirements. Consider the 200mA current handling capability relative to the load conditions. Verify that the axial leaded package fits the available board space and mounting constraints.
Part Context
This part belongs to the standard 1N44xx series of small-signal switching diodes produced by Microchip Technology. These components are widely used in digital electronics for clamping, protection, and signal routing. The TR suffix indicates a specific bulk packaging method intended for surface mount or automated through-hole insertion processes.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Generic replacements must match the 75V PIV, 200mA IF, and DO-35 package dimensions.
