• Fast switching rectifier circuits

Diode Arrays Procurement Notes

Verify the manufacturer designation as Shenzhen Slkormicro Semicon Co., Ltd. against official component markings or datasheets. Confirm the specific suffix 'W' corresponds to the SOD-123 package style. Ensure compliance with RoHS and halogen-free requirements if specified in the official documentation. Cross-reference absolute maximum ratings with circuit design constraints.

Diode Arrays Selection Notes

Select this component when a fast-switching diode is required for LED lighting applications. The SOD-123 package is suitable for space-constrained surface-mount designs. Verify that the 100 V peak reverse voltage and 150 mA average forward current ratings exceed the operational demands of the target circuit. Consider thermal dissipation capabilities within the plastic package for continuous operation.

Diode Arrays Part Context

This component belongs to the standard 1N4148 family of small-signal switching diodes. While traditional variants often utilize DO-35 axial glass packages, the WL suffix indicates a surface-mount configuration. This variant maintains the core switching performance of the series while adapting to modern PCB assembly techniques through its SOD-123 form factor.

Diode Arrays Replacement Considerations

Compatible substitutes include 1N4148WS (onsemi) and LL4148 (onsemi). Other equivalents such as BAS16 or MMBD914 may be considered if pinout and package compatibility are verified.
