Additional Details

The TLPN137(TP1,F) consists of a gallium arsenide infrared emitting diode optically coupled to a silicon phototransistor. It has a typical forward voltage of 1.25V. The collector-emitter breakdown voltage is typically 70V. The response time is very fast, typically in the microseconds range. This allows for high-speed data transfer rates. The operating temperature range is -55°C to +100°C. The device is designed to meet stringent safety standards, including UL, CSA, and VDE. The device’s high common-mode transient immunity (CMTI) helps prevent spurious triggering in noisy environments.
