TLP351
Unit: mm
The TOSHIBA TLP351 consists of a GaAAs light emitting diode and a
integrated photodetector.
This unit is 8-lead DIP package.
TLP351 is suitable for gate driving circuit of IGBT or power MOS FET.
Especially TLP351 is capable of “direct” gate drive of lower Power IGBTs.

Note 3: Exponential waveform IOPH -0.4 A (2.0 ms), IOPL +0.4 A (2.0 ms),Ta = 100°C
Note 4: It is 2 mm or more from a lead root.
Note 5: Device considerd a two terminal device: pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted
together.
Note 6: A ceramic capacitor(0.1 mF) should be connected from pin 8 to pin 5 to stabilize the operation of the high
gain linear amplifier. Failure to provide the bypassing may impair the switching property.
The total lead length between capacitor and coupler should not exceed 1 cm.
