1N4148TA

Single Diodes Overview

The Fairchild Semiconductor 1N4148TA is a small-signal switching diode housed in the DO-35 axial leaded package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 200 mA. The device exhibits a fast reverse recovery time of 4 ns, making it suitable for high-frequency applications. It operates within a junction temperature range of -65 °C to +175 °C and has a thermal resistance of 300 °C/W. The component is RoHS compliant and lead-free.

Single Diodes Feature Summary

• Fast switching capability with a 4 ns reverse recovery time
• High-temperature operation up to 175 °C
• Glass-passated silicon junction for stability
• Standard axial DO-35 through-hole packaging

Single Diodes Applications

• General-purpose signal switching
• Clamping and protection circuits
• High-speed digital logic interfaces

Single Diodes Procurement Notes

Verify the manufacturer date code and lot traceability upon receipt. Confirm that the physical marking on the DO-35 glass body matches the 1N4148TA designation. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status as specified by Fairchild Semiconductor standards.

Single Diodes Selection Notes

Select this component when a standard axial leaded form factor is required for through-hole assembly. The 1N4148TA is appropriate for low-power signal processing tasks where moderate current handling and fast recovery are necessary. Consider surface mount alternatives like the 1N4148WS if board space constraints preclude the use of the larger DO-35 package.

Single Diodes Part Context

The 1N4148TA is part of the widely used 1N4148 family of small-signal switching diodes manufactured by Fairchild Semiconductor. This specific suffix 'TA' typically denotes the axial leaded DO-35 package variant. The device serves as a fundamental discrete semiconductor component for rectification and switching in consumer electronics and industrial control systems.

Single Diodes Replacement Considerations

The 1N914 is a direct functional substitute with identical electrical characteristics. Other manufacturers produce equivalent parts under the same 1N4148 designation, provided they meet the 100V PIV and 200mA IF specifications.
