Littelfuse AQ1205-01UTG Bidirectional Discrete TVS Diode

Littelfuse AQ1205-01UTG Bidirectional Discrete TVS Diode is fabricated using proprietary silicon avalanche technology. This diode provides an Electrostatic Discharge (ESD) protection level for electronic equipment. The AQ1205-01UTG TVS diode safely absorbs repetitive ESD strikes of ±30kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. This diode features a 20nA reverse leakage current (VR = 4.5V) and 9pF maximum capacitance. The AQ1205-01UTG TVS diode is AEC-Q101 qualified and PPAP capable. This diode is Halogen and lead-free, and RoHS-compliant. Typical applications include automotive, battery protection, BMS, computer peripherals, medical equipment, notebooks/desktops/servers, Point-of-Sale terminals, switches/buttons, and test equipment/instrumentation.
