1N4148WSR13

Single Diodes Overview

The Diotec Semiconductor 1N4148WSR13 is a surface-mount small signal switching diode housed in an SOD-323F package. It features a maximum average forward current of 150 mA and a repetitive peak reverse voltage of 100 V. The device exhibits a reverse recovery time of less than 4 ns, with a typical junction capacitance of 2 pF at 0 V. Forward voltage is specified as less than 0.855 V at 10 mA. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Very high switching speed suitable for fast signal processing
• Low junction capacitance and low leakage current
• Compliant with RoHS directives without exemptions

Single Diodes Applications

• Signal processing circuits
• High-speed switching applications
• Commercial and industrial grade electronics

Single Diodes Procurement Notes

Verify the specific suffix R13 indicates a 13-inch reel configuration upon ordering. Confirm whether AEC-Q101 automotive standards are required, as standard versions differ from -Q or -AQ variants. Ensure design accounts for thermal resistance on PCBs with 3 mm² copper pads. Check REACH and conflict mineral compliance documentation before final integration.

Single Diodes Selection Notes

Select this component for designs requiring compact SMD packaging with rapid switching capabilities. The SOD-323F form factor supports automated insertion. Consider the 150 mA continuous current limit and 100 V reverse voltage rating against circuit demands. Verify thermal management requirements given the 200 mW power dissipation capability.

Single Diodes Part Context

This part belongs to the 1N4148/1N4448 series of silicon epitaxial planar diodes manufactured by Diotec Semiconductor. It serves as a surface-mount alternative to through-hole variants like the DO-35 package. The series is widely used in general-purpose switching tasks across consumer and industrial electronics sectors.

Single Diodes Replacement Considerations

Cross-reference with other SOD-323F small signal diodes offering similar trr and VRRM specifications. Verify pinout compatibility and electrical parameter overlaps such as forward voltage and leakage current before substitution.
