Single Diodes Procurement Notes

Verify the manufacturer designation as ANBON SEMICONDUCTOR (INT'L) LIMITED against the specific datasheet provided. Confirm the SOD-523 package outline dimensions and marking code T4 match the required board layout. Ensure electrical parameters such as the 150 mA forward current and 75 V reverse voltage ratings align with the circuit design requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a small surface-mount footprint is required alongside fast switching capabilities. The SOD-523 package offers space efficiency compared to through-hole alternatives. Consider the 150 mA continuous current rating and 150 mW power dissipation limits for thermal management. Verify that the 4 ns reverse recovery time meets the frequency requirements of the target application.

Single Diodes Part Context

This part belongs to the family of silicon planar switching diodes designed for general-purpose high-speed applications. The 1N4148WT variant specifically utilizes the SOD-523 plastic encapsulate format. It serves as a compact alternative to traditional axial leaded packages while maintaining comparable electrical performance for signal switching tasks.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N4148 designation in SOD-523 packages. Verify pinout compatibility and ensure equivalent electrical ratings for voltage, current, and switching speed are met by potential substitutes.
