TLP270D is a photocoupler produced by Toshiba. It can be used in mobile phones, notebooks, PDAs, multimedia devices, televisions, modems and other electronic devices.
The Toshiba TLP270D is a fully integrated photocoupler that combines a photorelay, photocoupler, Darlington transistor, bridge rectifier, and Zener diode in a 14‑pin SOP package. It is intended for use in DAA circuits for modems, PDAs, multimedia TVs, and other general electronics applications.
The document provides maximum ratings, individual and coupled electrical characteristics, switching performance, package limits, and safety restrictions. Key parameters such as isolation voltage, current transfer ratio, and on‑state currents are listed to aid designers in selecting the device for their circuits.
| Peak off‑state voltage | 200 V (min) |
|---|---|
| Trigger LED current | 3 mA (max) |
| On‑state current | 150 mA (max) |
| Current transfer ratio (CTR) | 50 % (min) |
| Isolation voltage | 1500 Vrms (min) |
| Forward current (photorelay) | 50 mA |
| Junction temperature limit | 125 °C |
The device provides an isolation voltage of at least 1500 Vrms.
The maximum forward current is rated at 50 mA.
The typical CTR is 50 % or higher.
