Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’m blocked from reviewing or updating the part because this account currently has no available ACUs, so I can’t inspect the project, search for the datasheet, or mutate the Datasheet property.
What I accomplished so far:
Identified the requested task: verify SFH_7250 part metadata, official datasheet, schematic symbol, footprint, and pin descriptions.
Noted the project context available here: SFH_7250, described as an 850 nm IR emitter, 1.6 V, 70 mA, 10 mW/sr @ 70 mA, 120°, 4-PLCC, 4 pads.
What remains to be done once ACUs are available:
Inspect existing MPN, package, pin count, description, and properties.
Find the official manufacturer datasheet if no Datasheet URL is set.
Update the part’s Datasheet property.
Cross-check symbol pins, footprint pad count/geometry, and pin descriptions against the datasheet.
Summarize key electrical/optical/mechanical specs and flag any mismatches.

Reflective Optical Sensor (Photointerrupter) – Reflective infrared optical sensor integrating an 850 nm IR emitter and silicon phototransistor receiver for object detection, proximity sensing, position detection, paper/media sensing, and industrial automation. Features a 2.3 mm sensing distance, daylight-blocking optical filter, and high ambient light immunity for reliable reflective detection. Operates with an IR LED forward current up to 50 mA, 1.25 V typical forward voltage, and a phototransistor collector-emitter voltage of up to 70 V. Provides fast response times, surface-mount (SMD) construction, and is specified for operation over a −40°C to +100°C temperature range. Housed in a 4-pin SMD reflective sensor package measuring approximately 4.2 × 2.5 × 1.7 mm. (ams-OSRAM)
