The 4N38 is a single-channel optocoupler with a phototransistor output and base connection, designed for electrical isolation in applications such as AC mains detection, logic coupling, and switch mode power supply feedback. It is housed in an industry-standard dual-in-line 6-pin package with a 400 mil lead pitch and is available in surface-mount SMD-6 options. The device provides 5000 V RMS isolation voltage, meets UL 94 V-0 flammability rating, and complies with RoHS Directive 2002/95/EC. The current transfer ratio is a minimum of 20% at an input current of 20 mA and collector-emitter voltage of 10 V. Turn-on and turn-off times are both specified at 10 μs with a 100 Ω load. It operates over a temperature range of -55 °C to +100 °C and is certified to BSI EN 60065 and EN 60950-1 standards.
