1N4148-T

Single Diodes Overview

The Lumimax Optoelectronic Technology 1N4148-T is a silicon epitaxial planar switching diode housed in a DO-35 glass case. It features a maximum repetitive peak reverse voltage of 75 V and a non-repetitive peak reverse voltage of 100 V. The device supports a continuous forward current of 300 mA with a maximum instantaneous forward voltage of 1.0 V at 10 mA. Key electrical characteristics include a typical junction capacitance of 4.0 pF, a maximum reverse recovery time of 4 ns, and a power dissipation rating of 500 mW. The component operates within a temperature range of -65°C to +175°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the requested variant matches the required voltage and current ratings for the target application environment. Cross-reference the datasheet revision date to confirm the validity of the thermal and electrical parameters provided.

Single Diodes Selection Notes

Select this component when a standard small-signal switching diode is required in an axial glass package. Consider the 4 ns reverse recovery time for high-frequency operations. Evaluate the 75 V reverse voltage rating against circuit peak voltages. Confirm compatibility with automated insertion equipment if surface mount alternatives like the SOD-123 version are not suitable.

Single Diodes Part Context

This part belongs to the widely used 1N4148 family of fast-switching diodes. Lumimax offers equivalent variants in different packages, including the SOD-123 (1N4148W), Quadro MELF (LS4148), and Mini-MELF (LL4148). The DO-35 package provides a traditional through-hole form factor suitable for legacy designs or specific mechanical constraints.

Single Diodes Replacement Considerations

Direct substitutes include the 1N914 diode, which is electrically equivalent. Other manufacturers produce identical specifications under the 1N4148 designation. Verify pinout polarity and package dimensions when replacing with generic equivalents from other suppliers.
