The collentor-emitter diode is a parasitic structure and should not be used to conduct current.If the collector(s) go below ground an external Schoottky diode should be added to clamp negative undershoots. www.belling.com.cn 2 V1.1 ULN2003 Absolute Maximum Ratings (1) At 25°C free-air temperature (unless otherwise noted) Symbol Parameter VCC Collector to emitter voltage 50 V VR VI Clamp diode reverse voltage(2) Input voltage(2) Peak collector current 50 30 500 V V mA mA ICP Min See typical characteristics Max Unit IOK ITE Output clamp current 500 Total emitter-terminal current –2.5 A TA Operating free-air temperature range 70 °C –20 θJA Thermal Resistance Junction-to-Ambient(3) 63 θJC Thermal Resistance Junction-to-Case(4) 12 °C/W TJ Operating virtual junction temperature 150 °C TSTG Storage temperature range –65 150 °C ESD Human Body Mode -- 3000 V (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted. (3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (4) Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability. www.belling.com.cn 3 V1.1 ULN2003 Electrical Characteristics(TA=+25℃, unless otherwise specified) Parameter V I(on) V CE(sat) I CEX V On-state input voltage Collector-emitter saturation voltage Test Figure ULN2003 Test Conditions MIN TYP MAX IC = 200 mA -- -- 2.4 IC = 250 mA -- -- 2.7 IC = 300 mA -- -- 3 II = 250 μA, IC = 100 mA -- 0.9 1.1 II = 350 μA, IC = 200 mA -- 1 1.3 II = 500 μA, IC = 350 mA -- 1.2 1.6 Figure 1 VCE = 50 V, II = 0 -- -- 50 Figure 2 VCE = 50 V, TA = +105°C II = 0 -- -- 100 Figure 6 Figure 5 Collector cutoff current VCE = 2 V Unit V V μA F Clamp forward voltage Figure 8 IF = 350 mA -- 1.7 2 V I(off) Off-state input current Figure 3 VCE = 50 V, IC = 500 μA 50 65 -- μA II Input current Figure 4 VI = 3.85 V 0.93 1.35 mA IR Clamp reverse current Figure 7 --- 100 Ci Input capacitance ----- 15 25 I VR = 50 V VI = 0, TA = 70°C f = 1 MHz 50 μA pF Switching Characteristics (TA = +25°C, unless otherwise specified) Parameter ULN2003 Test Conditions MIN t PLH t PHL V OH Propagation delay time, low- to high-level output Propagation delay time, high- to low-level output High-level output voltage after switching www.belling.com.cn UNIT TYP MAX See Figure 9 0.25 1 μs See Figure 9 0.25 1 μs VS = 50 V, IO = 300 mA, VS–20 See Figure 9 4 mV V1.1 ULN2003 Parameter Measurement Information www.belling.com.cn 5 V1.1 ULN2003 Notes: 8.
