The Darlington configuration delivers a minimum DC current gain of 1000 at 350 mA, so a microcontroller GPIO can switch a relay coil, solenoid, or lamp directly without a driver transistor stage. This is the automotive-grade variant, qualified to AEC-Q100, and rated for junction temperatures up to 150 °C — suitable for under-hood or engine-bay environments where the commercial ULN2003 family would exceed its thermal budget. The saturation voltage is 1.6 V maximum at 500 µA base drive and 350 mA collector current, leaving enough headroom for a 12 V or 24 V automotive supply rail to deliver a clean logic-level output. ## What the 50 V / 500 mA rating means for the BOM The 50 V VCEO breakdown covers the 12 V and 24 V automotive rails with margin for load-dump transients that can spike above 40 V. The 500 mA per-channel limit is a per-output ceiling, not a package total — the SOIC-16's thermal resistance means you derate if driving several channels at the full 500 mA simultaneously. For a typical relay or small solenoid the 350 mA test point is the practical continuous load. ## Automotive qualification and lifecycle It is part of the Automotive, AEC-Q100 series, which means each device has passed the stress tests required for automotive-grade qualification — temperature cycling, HBM ESD, and high-temperature operating life.","metaTitle":"STMicroelectronics ULQ2003D1013TRY 7 NPN Darlington","metaDescription":"ST ULQ2003D1013TRY automotive AEC-Q100 7 NPN Darlington transistor array. 50V VCEO, 500mA per channel, 150°C TJ, SOIC-16.
