✅ Manufacturer: Littelfuse Inc., which satisfies the AVL requirement.
✅ DigiKey category: Circuit Protection → Transient Voltage Suppressors (TVS) → TVS Diodes.
✅ Bidirectional Channels: 1, matching the requirement for bidirectional ESD protection on a single GPIO line.
✅ Voltage - Reverse Standoff (Typ): 5V, which is within the required 5V to 6.5V range and is appropriate for 3.3V GPIO.
✅ Voltage - Clamping (Max) @ Ipp: 18V, which satisfies the ≤20V requirement.
✅ Capacitance @ Frequency: 0.15pF @ 3GHz, which is well below the ≤50pF limit.
✅ Mounting Type: Surface Mount, as required.
✅ Package / Case: SC-76, SOD-323; includes SOD-323 as required.
✅ Operating Temperature: -40°C to 150°C, which meets and exceeds the required -40°C to +125°C range.
✅ RoHS Compliance: ROHS3 Compliant, satisfying the RoHS requirement.
All listed requirements are satisfied. This Littelfuse AQ3522-01FTG is approved for 3.3V MCU GPIO ESD protection.
