PS2403-3** is a **photocoupler (optoisolator)** manufactured by **NEC (now part of Renesas Electronics)**.

The PS2403-3 is a photocoupler (optoisolator) manufactured by NEC (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

Specifications:

  • Type: Phototransistor Output Optocoupler
  • Isolation Voltage: 5000Vrms (min)
  • Collector-Emitter Voltage (VCEO): 80V
  • Collector Current (IC): 50mA (max)
  • Current Transfer Ratio (CTR): 50% (min at IF = 5mA, VCE = 5V)
  • Input Forward Current (IF): 60mA (max)
  • Forward Voltage (VF): 1.5V (max at IF = 20mA)
  • Response Time (tPLH, tPHL): 3μs (typical)
  • Operating Temperature Range: -55°C to +100°C

Description:

The PS2403-3 is a high-speed, high-isolation voltage photocoupler designed for signal isolation in industrial, communication, and control applications. It consists of an infrared LED optically coupled to a phototransistor, providing electrical isolation between input and output circuits.

Features:

  • High isolation voltage (5000Vrms)
  • Fast response time (3μs typical)
  • High current transfer ratio (CTR ≥ 50%)
  • Wide operating temperature range (-55°C to +100°C)
  • Compact DIP-4 package
  • Suitable for digital and analog signal isolation

This optocoupler is commonly used in power supplies, PLCs, motor controls, and communication interfaces where electrical isolation is required.

(Note: Always refer to the latest datasheet for detailed specifications.)
