Additional Details:

The ELM453 phototransistor operates within a specified collector-emitter voltage range, typically around 30V, and a collector current range that depends on the incident light. The spectral sensitivity is highest in the near-infrared region, but it also responds well to visible light. The operating temperature range typically spans from -25°C to +85°C, ensuring robust performance in various operating conditions. It's often used with a current limiting resistor to protect the phototransistor.
