Overview
The Microchip Technology 1N4438FT is a small signal switching diode designed for high-speed applications. It features a peak repetitive reverse voltage of 100 V and a maximum average forward rectified current of 200 mA. The device operates with a low forward voltage drop and fast recovery characteristics, making it suitable for computer logic circuits. It is housed in the DO-35 axial leaded package and supports through-hole mounting. The component is rated for a maximum power dissipation of 500 mW and functions within a temperature range from -65 °C to +200 °C.
Feature Summary
- High-speed switching capability optimized for digital logic and computer applications
- Robust thermal performance supporting junction temperatures up to 200 °C
- Standardized DO-35 axial leaded package for reliable through-hole integration
Applications
- Computer logic circuits
- General-purpose signal switching
- Clamping and protection in digital systems
Procurement Notes
Verify the specific suffix 'FT' against the official Microchip datasheet to confirm tape and reel packaging specifications. Ensure the order quantity aligns with manufacturer minimums. Cross-reference the full part number with authorized distributors to confirm availability and authenticity before finalizing procurement.
Selection Notes
Select this component when a standard silicon switching diode with 100 V reverse voltage and 200 mA forward current is required. The DO-35 package is ideal for through-hole designs. Consider the 200 °C junction temperature rating for high-thermal environments. Verify that the switching speed meets the specific circuit timing requirements compared to other general-purpose diodes.
Part Context
The 1N4438 series belongs to Microchip's lineup of small signal switching diodes. These components are widely used in digital electronics for their reliability and standardized electrical characteristics. The 1N4438 variant specifically offers a 100 V reverse voltage rating, distinguishing it from lower-voltage counterparts like the 1N4148 while maintaining similar form factors.
Replacement Considerations
Compatible substitutes include the 1N4148WS, 1N914, and BAS70-04. Verify that replacement parts match the 100 V reverse voltage and 200 mA forward current ratings. Ensure the alternative component supports the required DO-35 or equivalent package style for physical compatibility.
