The Darlington configuration delivers a high current gain — each channel saturates at 1.6 V max with 500 µA base drive and 350 mA load, so a 5 V logic output from a PLC or microcontroller can switch a 350 mA relay coil or solenoid directly without an external driver transistor. The AEC-Q100 marking on the part body is a common target for re-marking, so visual inspection and decap verification are standard steps before use in a production batch.","metaTitle":"ULN2803ADW 8 NPN Darlington Array, 50V 500mA, AEC-Q100","metaDescription":"Texas Instruments ULN2803ADW 8-channel NPN Darlington array, 50V Vceo, 500mA Ic max, AEC-Q100 qualified for automotive.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tube","Power - Max":"-","Mounting Type":"Surface Mount","Package / Case":"18-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Obsolete","Transistor Type":"8 NPN Darlington","lifecycle_stage":"eol_hot","Base Product Number":"ULN2803","Operating Temperature":"-40°C~85°C(TA)","Frequency - Transition":"-","Supplier Device Package":"18-SOIC","Vce Saturation (Max) @ Ib, Ic":"1.6V @ 500µA, 350mA","Current - Collector (Ic) (Max)":"500mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"-","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/21b2b800bbdd24fddb5cb19410f89e2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ULN2803ADW/alternatives.json"},"ai":{"faq":[{"question":"Is ULN2803ADW obsolete?","answer":"Yes, Texas Instruments has classified the ULN2803ADW as Obsolete.
