TLP126 Description

Short technical summary and product information.

The Toshiba TLP126 is a compact mini flat photocoupler designed for surface mount applications. It integrates a gallium arsenide infrared emitting diode with a phototransistor, providing high current transfer ratio (CTR) at low AC input current. Key electrical specifications include a minimum isolation voltage of 3750Vrms, a collector-emitter voltage of 80V, and a minimum CTR of 100%.

 

This device is suitable for applications such as programmable controllers and AC/DC input modules. Its small outline package and surface mount capability make it ideal for space-constrained designs. The operating temperature range is -55 to 100 °C, and it has a lead soldering temperature of 260 °C for 10 seconds.

 

The TLP126 operates with a supply voltage up to 48V and a forward current up to 20mA. It features a typical forward voltage of 1.15V at 10mA and a collector-emitter saturation voltage of 0.2V typical. The device also specifies a minimum collector-emitter breakdown voltage of 80V and a minimum emitter-collector breakdown voltage of 7V.
