Phototriac coupler with high noise immunity suits high component density designs

Toshiba Electronics Europe (TEE) has extended its family of phototriac couplers with an ultra miniature device that is ideal for high component density applications.

The TLP163J offers improved immunity against external noise and is supplied in a compact, low-profile MFSOP6 SMT package measuring just 4.4mm x 3.6mm x 2.5mm. Target applications will include solid state relays, home appliance control systems, office automation equipment and other high density designs where designers are looking to save space and weight.

Approved to international safety standards, the TLP163J offers an AC insulation voltage rating of 5000Vrms (minimum). Typical impulse noise immunity is rated at 2000V.

The TLP163J consists of a zero-crossing photo-triac output optically coupled to an infrared LED. Peak off-state voltage is 600V, effective on-state current is 70mA, and trigger LED current is 10mA.
