1N4448_T50R

Single Diodes Overview

The onsemi 1N4448_T50R is a small signal switching diode housed in the DO-204AH (DO-35) axial lead package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current of 200 mA. The device exhibits a fast reverse recovery time of 4.0 ns, with a maximum forward voltage of 0.72 V at 5.0 mA. Electrical characteristics include a breakdown voltage of 100 V at 100 µA and a total capacitance of 2.0 pF at 0 V reverse bias. Thermal performance allows for 500 mW power dissipation with a junction-to-ambient thermal resistance of 300 °C/W.

Single Diodes Feature Summary

• Fast switching capability with a reverse recovery time of 4.0 ns
• Hermetically sealed glass construction for environmental stability
• High surge current handling up to 4.0 A under specific pulse conditions

Single Diodes Applications

• High-speed switching circuits
• Signal rectification
• Clamping applications

Single Diodes Procurement Notes

Verify that the T50R suffix corresponds to the Tape and Reel packing method as defined in the official ordering information table. Confirm the package type matches the DO-204AH specification. Ensure compliance with RoHS directives by checking the specific product marking or datasheet revision for environmental declarations.

Single Diodes Selection Notes

Select this component when a high-speed silicon planar diode is required for general-purpose switching tasks. The 1N4448 variant offers higher DC forward current compared to standard 1N914 types. Verify that the 100 V reverse voltage rating meets the circuit's peak inverse voltage requirements.

Single Diodes Part Context

This part belongs to the 1N91x, 1N4x48, FDLL914, and FDLL4x48 family of small signal diodes manufactured by onsemi. The family shares common electrical characteristics but varies in packaging and specific voltage ratings. The 1N4448 designation specifically denotes the high-conductance version within this series.

Single Diodes Replacement Considerations

The 1N4148TR is listed as a tape and reel alternative within the same family. Other equivalents include the 1N914 variants, though their forward current ratings may differ.
