The TLP700 is ideal for saving space in applications that require the reinforced isolation demanded for international safety certification.

Toshiba Electronics Europe (TEE) has launched a miniature photocoupler that delivers the same isolation and current outputs as previous DIP packaged devices in a form factor that is 50% smaller.

The new TLP700 is ideal for saving space in applications that require the reinforced isolation demanded for international safety certification.

The TLP700 has an isolation voltage of 5000Vrms and a common mode transient immunity rating of +/-10kV/us.

Suitable for use in IGBT and power MOSFET gate drive circuits, the device has a peak output current of 2.0A, allowing it to directly drive some low power IGBTs up to around 50A.

Operating with a supply voltage between 15 and 30V, the TLP700 keeps power consumption to a minimum through a maximum supply current of just 2mA.

Maximum switching time is rated at 500ns.

The new photocoupler comprises a GaAlAs infra-red LED and a photodetector IC in the latest SDIP six-pin packaging measuring just 6.8 x 4.58 x 3.65mm.

The device has been designed to meet the requirements of all relevant international safety approvals and delivers guaranteed performance at temperatures between -40 and +100C.
