Unit in mm
The TOSHIBA TLP2631 dual photocoupler consists of a pair of GaAℓAs
light emitting diode and integrated high gain, high speed photodetector.
This unit is 8-lead DIP.
The output of the detector circuit is an open collector, Schottky clamped
transistor.
A Faraday shield integrated on the photodetector chip reduces the effects
of capacitive coupling between the input LED emitter and the high gain
stages of the detector. This provides an effective common mode transient
immunity of 1000V / μs.
• Input current threshold: I_F = 5mA(max.)
• Switching speed: 10MBd(typ.)
• Common mode transient immunity: ±1000V / μs(min.)
• Guaranteed performance over temperature: 0~70°C
• Isolation voltage: 2500V_rms(min.)
• UL recognized: UL1577, file no. E67349
