Additionally, to meet the growing demands of today's designs, Fairchild offers optocouplers capable of withstanding operating temperatures up to +125°C. Fairchild's FODM8801 OptoHiT™ high temperature phototransistor optocoupler is the only plastic package optocouplers capable of meeting this temperature limit enabling improved Current Transfer Ratio (CTR) stability at elevated temperatures. Our 4-Pin full pitch MFP and 4-Pin DIP, phototransistor output optocouplers are all rated with a maximum operation temperature of +110°C.
