Unit: mm
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.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 1: Derate 0.14 mA / °C above 70 °C.
Note 2: 50% duty cycle, 1ms pulse width.
Derate 0.29 mA / °C above 70 °C.
Note 3: Pulse width PW 1μs, 300pps.
Note 4: Derate 1.8 mW / °C above 70 °C.
Note 5: Device considered a two-terminal device: Pins1 and 3 are shorted together, and pins 4, 5 and 6 are
shorted together.
