1N4148T-77

Single Diodes Overview

The ROHM 1N4148T-77 is a high-speed switching diode constructed using silicon epitaxial planar technology. It features a glass-sealed axial leaded package (DO-35) designed for reliability and fast response. Key electrical parameters include a maximum repetitive reverse voltage of 100V, a continuous forward current rating of 150mA, and a peak forward surge current capability of 500mA. The device exhibits a low reverse recovery time of 4ns at 25°C, ensuring efficient performance in rapid switching applications.

Single Diodes Feature Summary

• Glass sealed envelope construction for enhanced environmental protection
• High speed operation with minimal reverse recovery time
• Silicon epitaxial planar design for consistent reliability

Single Diodes Applications

• High-speed switching circuits
• General purpose rectification
• Clamping and protection applications

Single Diodes Procurement Notes

Verify the specific suffix 'T-77' against official ROHM documentation to confirm packaging details such as reel specifications or tape-and-reel quantities. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the DO-35 package dimensions with your PCB footprint constraints before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a standard high-speed switching diode is required for general-purpose applications. The 100V reverse voltage rating suits most low-voltage logic and signal processing circuits. Consider the axial leaded form factor for through-hole mounting designs where surface mount alternatives are not feasible or preferred for mechanical stability.

Single Diodes Part Context

This part belongs to the 1N4148 family of switching diodes manufactured by ROHM Semiconductor. It shares characteristics with similar industry-standard parts like the 1N4448 but is distinguished by its specific axial leaded glass encapsulation. The product line focuses on providing reliable, cost-effective solutions for discrete semiconductor needs in consumer and industrial electronics.

Single Diodes Replacement Considerations

Equivalent parts include the 1N4448 and 1N4150 from the same manufacturer series. Verify pinout compatibility and ensure replacement components meet the same 100V reverse voltage and 150mA forward current ratings.
