Littelfuse AQ TVS Diode Arrays

Littelfuse AQ TVS Diode Arrays are designed to replace multilayer varistors (MLVs) in electronic equipment for low-speed and DC applications. The 450W discrete unidirectional TVS diodes will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The Littelfuse AQ series can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A (AQ05) of 8/20μs induced surge current (IEC 61000-4-5) with very low clamping voltages. AQ TVS diode arrays are AEC-Q101 qualified.
