JANTX4N48A

Transistor, Photovoltaic Output Optoisolators Overview

The JANTX4N48A is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output housed in a hermetically sealed TO-78-6 metal can package designed for through-hole mounting. The device provides an isolation voltage of 1000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a power dissipation rating of 300 mW, and a forward voltage of 1.5 V at 1 mA forward current. The current transfer ratio ranges from 100% to 500%, with rise and fall times specified at 20 µs each. It supports a maximum collector current of 50 mA and operates within a temperature range of -55°C to +125°C.
