Product details

What this photoelectric smoke detector IC does

The onsemi MC145012ED is a photoelectric smoke detector IC. It accepts input from a photoelectric sensor chamber and outputs a voltage signal. Supply current is 8 µA.

Package and mounting — through-hole for legacy and repair

Housed in a 16-lead DIP with 0.300" (7.62 mm) body width and through-hole mounting, the MC145012ED is a direct fit for existing smoke-detector PCB layouts that use the standard DIP footprint. The supplier device package is 16-PDIP. This package is easy to hand-solder and inspect, making it a practical choice for repair, retrofit, or low-volume production where surface-mount reflow is not available.

Rated for -10°C to 60°C operating temperature, this IC is intended for indoor environments.

Frequently asked questions

What is the supply current of MC145012ED?
