TLP520-2** is a photocoupler (optocoupler) manufactured by **TOSHIBA**.

The TLP520-2 is a photocoupler (optocoupler) manufactured by TOSHIBA. Below are its key specifications, descriptions, and features:

Specifications:

  • Type: Dual-channel photocoupler
  • Input Type: Infrared LED
  • Output Type: Phototransistor
  • Isolation Voltage (Viso): 2500 Vrms (min)
  • Collector-Emitter Voltage (VCEO): 55 V (max)
  • Collector Current (IC): 50 mA (max)
  • Current Transfer Ratio (CTR): 50% (min) at IF = 5 mA, VCE = 5 V
  • Turn-On Time (ton): 3 μs (max)
  • Turn-Off Time (toff): 4 μs (max)
  • Operating Temperature Range: -55°C to +110°C
  • Package: DIP-8

Descriptions:

  • The TLP520-2 consists of two independent GaAs infrared LEDs optically coupled to two silicon phototransistors in a single package.
  • It provides electrical isolation between input and output circuits, making it suitable for noise suppression and signal transmission in high-voltage environments.
  • Commonly used in digital logic isolation, power supply feedback control, and industrial automation systems.

Features:

  • Dual-channel isolation for compact circuit design.
  • High isolation voltage (2500 Vrms) ensures safety in high-voltage applications.
  • Fast response time (μs range) for efficient signal transmission.
  • Wide operating temperature range for industrial use.
  • Compliant with safety standards (UL, cUL, VDE).

For detailed electrical characteristics and application notes, refer to the official TOSHIBA datasheet.
