PC457

The PC457 is a kind of high speed and high CMR OPIC photocoupler. The typical applications include programmable controller and inverter.

There are some features of PC457 as follows: (1) high resistance to noise (CMR: MIN. 15 kV/s); (2) high speed response (tPHL: MAX. 0.8s, tPLH: MAX. 0.8s); (3) mini-flat package; (4) isolation voltage (Viso (rms): 2.5 kV); (5) recognized by UL.

What comes next is about the specifications of PC457. First is about the input part: (1): IF (forward current) is 25 mA; (2): VR (reverse voltage) is 5 V; (3): P (power dissipation) is 45 mW. Then is about the output part: (4): VCC (supply voltage) is from -0.5 to +30 V; (5): VO (output voltage) is from -0.5 to +20 V; (6): IO (output current) is 8 mA; (7): PO (power dissipation) is 100 mW; (8): Ptot (total power dissipation) is 100 mW; (9): Viso (isolation voltage) is 2.5 kV; (10): Topr (operating temperature) is from -40 to +100; (11): Tstg (storage temperature) is from -40 to +125; (12): Tsol (soldering temperature) is 260.
