BTB04-400D Description

Short technical summary and product information.

The STMicroelectronics BTB04-400D is a high-performance, glass-passivated PNPN device belonging to the BTB04 series of sensitive gate triacs. Designed for general-purpose applications requiring high gate sensitivity, this triac is suitable for 4-quadrant switching applications such as phase control.

 

Key electrical characteristics include an RMS on-state current of 4A at a case temperature of 95°C, a maximum gate trigger current (IGT) of 10mA, and a maximum holding current (IH) of 15mA. The device also offers an insulating voltage of 2500V(RMS) for the BTA family, with UL recognition.

 

Packaged in a standard TO-220AB case, the BTB04-400D is designed for through-hole mounting. Its sensitive gate design makes it ideal for applications where precise triggering is needed, contributing to efficient static switching and phase control circuits.

 

This triac family is part of STMicroelectronics' broader offering of Thyristors and AC Switches, providing reliable solutions for power control applications.
