TLP115 is a high performance optocoupler produced by TOSHIBA. It has the characteristics of high isolation voltage, high switching speed, small package and so on. It is widely used in microprocessor system interfaces, digital isolation, A/D, D/A conversion and other fields.
The TLP115 is a miniature GaAs optocoupler designed for surface‑mount assembly. It combines a light‑emitting diode with a high‑gain shielded photodetector, offering high speed, long‑distance isolation and common‑mode transient immunity.
The document lists maximum ratings, electrical and switching characteristics, test circuits, and safety restrictions. Key parameters include a 2500 Vrms isolation voltage, 4.5‑5.5 V supply range, typical propagation delay of about 80 ns, and operation from –40 °C to 85 °C.
| Isolation voltage (AC, 1 min) | 2500 Vrms (min) |
|---|---|
| Input current, high level (FH) | 16 mA (typ) |
| Supply voltage (Voc) | 4.5 V – 5.5 V |
The device provides a minimum isolation voltage of 2500 Vrms for AC operation.
A supply voltage between 4.5 V and 5.5 V is recommended.
The TLP115 operates from –40 °C to 85 °C and can be stored from –55 °C to 125 °C.
