The Toshiba 6N137 optocoupler combines a high‑emitting infrared diode with a photo‑IC in an 8‑lead DIP package. It is TTL compatible, operates from a 5 V supply, and provides up to 2500 Vrms isolation.
The document lists maximum ratings, recommended operating conditions, electrical and switching characteristics, and test circuits. It also includes temperature‑dependent forward‑current curves and reliability notes for proper use in digital logic isolation applications.
| Pulse Forward Current (Irp) | 40 mA |
|---|---|
| Reverse Voltage (VR) | 5 V |
| Output Current (Io) | 50 mA |
| Supply Voltage (VCC) | 5 V (typical) |
| Isolation Voltage | 2500 Vrms (min) |
| Operating Temperature Range | 0 °C to 70 °C |
| Storage Temperature Range | -55 °C to 125 °C |
It provides a minimum isolation voltage of 2500 Vrms.
The recommended supply voltage is 5 V (typical), not to exceed 5.5 V.
