1N4154TR

Single Diodes Overview

The Fairchild Semiconductor 1N4154TR is a small signal switching diode designed for high-speed applications. It features a single configuration housed in a DO-35-2 through-hole package. The device supports a peak reverse voltage of 35 V and a maximum forward current of 200 mA, with a surge current rating of 500 mA. It operates within a temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• High-speed switching capability suitable for computer diode applications
• Glass-sealed axial lead construction for environmental stability
• Low leakage current characteristics for efficient signal processing

Single Diodes Applications

• Signal rectification in electronic circuits
• Computer logic interface diodes
• High-speed switching applications

Single Diodes Procurement Notes

Verify the manufacturer designation on the component marking against official Microchip Technology documentation, as the 1N4154 series is currently manufactured by Microchip. Confirm that the specific suffix corresponds to the reel or cut tape packaging format required for your assembly process. Ensure compliance with RoHS directives if applicable to your project specifications.

Single Diodes Selection Notes

Select this component when a robust small-signal diode with a 35V reverse voltage rating is required. The DO-35 package is appropriate for through-hole mounting where space constraints are minimal. Consider the thermal operating limits up to 150°C for environments requiring extended temperature resilience compared to standard plastic packages.

Single Diodes Part Context

The 1N4154 is a legacy part number historically associated with Fairchild Semiconductor but is now produced under Microchip Technology ownership. It belongs to the family of general-purpose silicon switching diodes known for fast recovery times. The 'TR' suffix typically indicates a specific bulk or reel packaging variation distinct from standard retail units.

Single Diodes Replacement Considerations

The 1N4148 is a widely available substitute offering similar electrical characteristics in the same DO-35 package. Verify pin compatibility and ensure the replacement meets the specific 35V reverse voltage requirement if the original design relies on this margin.
