Single Diodes Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications against the official datasheet before procurement. Confirm that the AEC-Q101 qualification status aligns with your project's automotive reliability requirements. Ensure the SOT-23 footprint matches your PCB layout constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Validate thermal management capabilities for operation within the specified -55°C to +150°C junction temperature range.

Single Diodes Selection Notes

Select this component when a single high-voltage switching diode is required in a small surface-mount package. It is appropriate for designs needing AEC-Q101 compliance for automotive applications. Consider its 120 V reverse voltage rating for circuits exceeding standard low-voltage diode limits. Evaluate the 50 ns recovery time against your switching frequency requirements. Compare the 200 mA forward current capacity with your circuit's load demands to ensure adequate headroom.
