1N4447

Overview

The onsemi 1N4447 is a small signal switching diode housed in the DO-35 axial lead package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current rating of 200 mA. The device supports a non-repetitive peak forward surge current of up to 4 A for short pulses. Electrical characteristics include a maximum reverse recovery time of 4 ns, a forward voltage of 1.0 V at 20 mA, and a total capacitance of 2.0 pF. Thermal limits specify a power dissipation of 500 mW and a junction temperature capability of 175 °C.

Feature Summary

Fast switching performance with a reverse recovery time of 4 ns
High thermal stability supporting operation up to 175 °C junction temperature
Hermetically sealed glass construction ensuring environmental durability

Applications

General purpose signal switching circuits
High-speed digital logic interfacing
Clamping and protection applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets all required RoHS and REACH compliance standards for your target market. Ensure the selected variant matches the intended through-hole mounting requirements and bulk bag shipping specifications provided by the manufacturer.

Selection Notes

Select this component when fast switching speeds are critical for signal integrity. The 100 V breakdown voltage provides adequate margin for low-voltage logic systems. Verify that the 200 mA continuous current rating aligns with the circuit's load requirements. Consider the DO-35 package dimensions for PCB layout constraints.

Part Context

This part belongs to the standard small-signal diode family designed for general-purpose applications. It utilizes silicon technology within a glass-encapsulated axial lead frame. The device is optimized for high-speed switching tasks where low capacitance and rapid recovery times are necessary for efficient signal processing.
