4N38 - Optocoupler / Phototransistor

Download the 4N38 datasheet PDF. This datasheet also covers the 4N35-X variant, as both devices belong to the same optocoupler / phototransistor family and are provided as variant models within a single manufacturer datasheet.

General Description

This datasheet presents five families of Vishay industry standard single channel phototransistor couplers.

These families include the 4N35, 4N36, 4N37, 4N38 couplers.

Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor.

Key Features

  • Isolation test voltage 5000 VRMS.
  • Interfaces with common logic families.
  • Input-output coupling capacitance < 0.5 pF.
  • Industry standard dual-in-line 6 pin package.
  • Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC.

These families include the 4N35, 4N36, 4N37, 4N38 couplers. Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor. These couplers are Underwriters Laboratories (UL) listed to comply with a 5000 VRMS isolation test voltage. This isolation performance is accomplished through Vishay double molding isolation manufacturing process. Comliance to DIN EN 60747-5-5 partial discharge isolation specification is available for these families by ordering option 1.
