Supervisors Procurement Notes

Verify the specific suffix 'C3' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOT-323-3 package. Confirm RoHS compliance status through the latest environmental declaration documents provided by Diodes Incorporated prior to final procurement.

Supervisors Selection Notes

Select this component when a fixed 2.9 V threshold is required for system supervision. The wide operating temperature range up to +150 °C makes it suitable for harsh environments. Consider the 1 µA quiescent current for efficiency-critical designs. Verify that the open-drain output configuration aligns with the downstream logic requirements of the monitored circuit.
