4N38M datasheet



The 4N38M, H11DXM and MOC8204M are photo transistor-type optically coupled optoisolators. A gallium arsenide infrared emitting diode is coupled with a high
voltage NPN silicon phototransistor. The device is supplied in a standard plastic six-pin dual-in-line package.


1. High voltage :
(1) MOC8204M, BVCER= 400V
(2) H11D1M, H11D2M, BVCER= 300V
(3) H11D3M, BVCER= 200V

2. High isolation voltage : 7500 VACpeak, 1 second

3. Underwriters Laboratory (UL) recognized File # E90700, Volume 2

4. IEC 60747-5-2 approved (ordering option V)
