Overview
The Fairchild Semiconductor 1N914ATR is a small-signal switching diode designed for high-speed applications. It utilizes silicon epitaxial planar technology to achieve fast recovery times and low leakage currents. The device is housed in a DO-35 glass passivated axial leaded package, providing reliable performance in compact circuit designs. It serves as a general-purpose component for signal rectification and protection.
Feature Summary
- Fast switching capability with low reverse recovery time
- High isolation due to low leakage current
- Robust construction using silicon epitaxial planar process
Applications
- Signal rectification in electronic circuits
- Protection against voltage spikes
- Clamping and clipping applications
Procurement Notes
Verify the specific manufacturer datasheet for the 1N914ATR to confirm exact electrical parameters such as peak inverse voltage and forward current ratings. Ensure the DO-35 package dimensions match your PCB footprint requirements. Cross-reference with equivalent part numbers from other manufacturers if supply constraints exist, checking for pinout compatibility.
Selection Notes
Select this component when a standard fast-switching diode is required for low-power signal processing. Consider the axial leaded package for through-hole mounting or manual assembly processes. Evaluate thermal dissipation needs, as the DO-35 package has limited power handling capabilities compared to surface-mount alternatives.
Part Context
The 1N914 series is a widely recognized family of small-signal switching diodes. The 'A' suffix often denotes specific binning or manufacturing revisions, while 'TR' indicates tape and reel packaging. This part belongs to the broader category of general-purpose silicon rectifiers used in consumer and industrial electronics.
Replacement Considerations
Equivalent parts include the 1N914B and 1N4148. Verify that substitute components meet the same voltage and current specifications. Check for package compatibility, as some equivalents may differ in physical dimensions or lead spacing.
