Overview
Description
The TLP185GB is an optoisolator (optocoupler) from Toshiba, designed for signal isolation in electronic circuits. It features a GaAs infrared LED paired with a phototransistor, providing electrical isolation between input and output (up to 5kVrms).
Key specifications:
- High isolation voltage: 5kVrms
- Low power consumption (IF = 5mA typical)
- Fast response time (tr/tf ≈ 3μs)
- Wide operating temperature: -55°C to +110°C
- Compact 4-pin DIP package
Common applications include noise suppression, logic level shifting, and isolating digital signals in industrial, automotive, and consumer electronics.
The "GB" suffix indicates lead-free (RoHS-compliant) packaging. For detailed specs, refer to Toshiba’s datasheet.

Pinout
The TLP185GB is a 4-pin photocoupler (optoisolator) with the following functions:
1. Anode (Pin 1) – LED input (+)
2. Cathode (Pin 2) – LED input (-)
3. Emitter (Pin 3) – Phototransistor output (ground side)
4. Collector (Pin 4) – Phototransistor output (supply side)
It provides 5 kV isolation and is commonly used for signal isolation in industrial and consumer electronics. The output is an NPN phototransistor, making it suitable for switching or digital signal transfer.
