1N914-1

Overview

The Microchip Technology 1N914-1 is a standard rectifier diode designed for general-purpose switching applications. It features a single silicon element capable of handling a maximum output current of 200mA (0.2A). The component is encapsulated in a DO-204AH axial leaded package, providing a robust physical form factor for through-hole mounting. This device serves as a high-speed switching solution with a voltage rating of 75V, suitable for various electronic circuits requiring reliable unidirectional current flow.

Feature Summary

• High-speed switching capability for fast signal processing
• Hermetically sealed glass package for environmental protection
• Standard unidirectional current conduction

Applications

• General-purpose signal rectification
• Clamping and protection circuits
• Logic level shifting

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Microchip acquired assets from companies like Microsemi and Fairchild. Confirm that the DO-204AH package matches your PCB footprint requirements. Ensure compliance with relevant export control classifications (EAR99) if applicable to your region. Check for RoHS status variations across different production batches or legacy stock sources.

Selection Notes

Select this component when a hermetically sealed, axial-leaded diode is required for high-reliability environments. It offers a direct pin-compatible alternative to other small-signal switching diodes like the 1N4148 in through-hole designs. Consider the 75V reverse voltage rating to ensure adequate margin for your circuit's peak inverse voltage conditions.

Part Context

The 1N914 series is a widely recognized standard for small-signal switching diodes. Microchip Technology continues to support this part number following its acquisition of semiconductor assets from previous manufacturers such as Microsemi and Fairchild Semiconductor. The -1 suffix typically denotes the specific axial DO-204AH package variant within the broader 1N914 family.

Replacement Considerations

The 1N4148 is a common functional substitute, though it often utilizes a plastic SOD-123 or similar package rather than the hermetically sealed glass construction of the 1N914-1. Verify package compatibility and thermal characteristics before substitution.
