The TOSHIBA mini flat coupler TLP115 is small outline coupler, suitable
for surface mount assembly.
TLP115 consists of a GaAℓAs light emitting diode, optically coupled to an
integrated high gain, high speed shielded photo detector whose output is
an open collector schottky clamped transistor.
The shield, which shunts capacitively coupled common noise to ground,
provides a guaranteed transient immunity specification of 1000V / µs.
· Input current thresholds: I
· Switching speed: 10MBd (typ.)
· Common mode transient immunity: ±1000V / µs (min.)
· Guaranteed performance over temp.: 0~70°C
· Isolation voltage: 2500Vrms (min.)
· UL recognized: UL1577, file no. E67349
