800nm top-view phototransistor — key parametrics for the BOM
The SCM-014TBT86 is a phototransistor from ROHM Semiconductor, sensitive at 800nm with a top-view orientation, packaged in a 2-lead SMD (2SMD). It switches up to 30 mA at a supply voltage of 32 V, dissipating 0.1 W. The 800 nm peak sensitivity aligns with common IR LED emitters — typical in optical interrupters, reflective sensors, and ambient-light detection circuits where the phototransistor acts as the receiver side of a paired optocoupler or through-beam path.
Temperature grade and operating range
Rated for -30°C to +85°C ambient (TA), this part fits indoor and sheltered outdoor enclosures — think appliance control boards, HVAC sensor modules, or office-automation equipment where the ambient stays within that band. The 32 V supply ceiling gives headroom for a 24 VDC rail with margin; the 30 mA switching current is adequate for driving a logic input or a small-signal relay coil through a transistor buffer.
Active lifecycle — sourcing posture
The 2SMD footprint is compact — verify the pad layout against the ROHM recommended land pattern before committing the PCB.
