- This an Optoisolator with NPN transistor for output and has following
- characteristics:
-
- VISO = 7500 V (Isolation Voltage)
- PT = 250 mW (Total Power)
- CTR = 20 % (Current Transfer Ratio)
- If = 80 mA (Maximum Forward Current)
- Vr = 3 V (Maximum reverse Voltage)
- BVCBO = 70 V (Max. Collector to base Votage)
- BVceo = 30 V (Max. Collector to Emitter Voltage)
- IC = 100 nA (Max Collector Dark Current)
