Single Diodes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Comchip Technology before integration. Confirm that the SOD-323-2 footprint matches your PCB layout requirements. Ensure the 100 V reverse voltage rating meets your circuit's peak inverse voltage demands. Cross-reference the 150 mA forward current limit against your application's load conditions to prevent thermal overload during operation.

Single Diodes Selection Notes

Select this component when a compact, fast-switching diode is required for low-power signal handling. The 100 V rating provides adequate margin for standard logic-level circuits. Consider the 200 mW power dissipation limit when designing thermal management strategies. The SOD-323-2 package offers a smaller footprint compared to traditional axial leads, making it ideal for modern automated assembly processes.
