Q4004R4 Description

Short technical summary and product information.

The Littelfuse Q4004R4 is a 4 Amp bi-directional solid state switch designed for AC switching and phase control applications. This series guarantees gate control in Quadrants I & IV, making it suitable for digital control circuitry. It is ideal for applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays.

 

Key electrical specifications include a repetitive peak off-state voltage (VDRM) of 400V, an on-state current (Itrms) of 4A, and a non-repetitive surge current (ITSM) of 55A at 60Hz. The device also features a di/dt rating of 50A/μs at 110°C and a maximum on-state voltage (VTM) of 1.6V.

 

Packaged in a TO-220 non-isolated tab, the Q4004R4 is designed for through-hole mounting. Its specifications make it a reliable component for various industrial control systems requiring precise AC power management.
