The TOSHIBA TLX9309 mini-flat photocoupler is suitable for surface-mount

assembly.

The TLX9309 consists of a high-output light emitting diode optically coupled

to a high-speed detector, which consists of a photodiode and a transistor

integrated on a single chip.

Faraday shield integrated on the photodetector chip provides an enhanced

common-mode transient immunity.

The TLX9309 guarantees minimum and maximum propagation

delay time, propagation delay difference between tpHL and tpLH, and high

common-mode transient immunity.

Therefore, the TLX9309 is suitable for isolation

interface between an IPM (intelligent power module) and a control IC

circuit in motor control applications.
