TLP127(TPL,U,F)** is an optocoupler (phototransistor output) manufactured by **TOSHIBA**.

The TLP127(TPL,U,F) is an optocoupler (phototransistor output) manufactured by TOSHIBA. Below are its key specifications, descriptions, and features:

Specifications:

  • Isolation Voltage: 5,000 Vrms (min)
  • Collector-Emitter Voltage (VCEO): 80 V (max)
  • Collector Current (IC): 50 mA (max)
  • Current Transfer Ratio (CTR): 50% (min) at IF = 5 mA, VCE = 5 V
  • Input Forward Current (IF): 50 mA (max)
  • Forward Voltage (VF): 1.3 V (typ) at IF = 20 mA
  • Turn-On Time (ton): 3 μs (max)
  • Turn-Off Time (toff): 4 μs (max)
  • Operating Temperature Range: -55°C to +110°C

Description:

The TLP127 is a high-speed phototransistor optocoupler designed for signal isolation in electronic circuits. It consists of a GaAs infrared LED optically coupled to a phototransistor, providing electrical isolation between input and output.

Features:

  • High-speed response (suitable for digital signal transmission)
  • High isolation voltage (5,000 Vrms)
  • Compact 4-pin DIP package
  • Low input current requirement
  • Reliable performance in harsh environments
  • Compliant with safety standards (UL, CSA, VDE)

This optocoupler is commonly used in industrial control systems, power supply feedback circuits, and communication interfaces where electrical isolation is required.

For detailed application notes and reliability data, refer to the TOSHIBA datasheet.
