The 50 V collector-emitter breakdown voltage and 150 °C maximum junction temperature define the safe operating area for driving inductive loads like relays, solenoids, and small stepper motors — the Darlington gain means the microcontroller port pins can switch them directly. ## Package and compliance Supplied in a tube, the 16-DIP (0.300\", 7.62 mm) footprint is a standard through-hole layout — no board respin needed if replacing an older Darlington array in the same socket. ROHS3 compliant, which covers the full RoHS exemption list including lead in high-melting-temperature solder.","metaTitle":"STMicroelectronics ULQ2003A 7 NPN Darlington, 500mA, 50V","metaDescription":"STMicroelectronics ULQ2003A 7 NPN Darlington transistor array. 500mA collector current, 50V Vce breakdown, 16-DIP package.
