1 / 6 page DDC144TU DUAL NPN TRANSISTORS WITH 47K OHM BASE RESISTOR General Description • DDC144TU is best suited for logic switching applications using control circuits like micro-controllers, comparators, etc. It features two discrete NPN transistors which can support maximum continuous current of 100 mA. NPN transistors can be used as a control and also these can be biased using higher supply voltages due to the built in current limiting base resistor of 47 K Ohm. The component devices can be used as a part of a circuit or as a stand alone discrete device. Features • Built in Base Resistors • Epitaxial Planar Die Construction • Lead Free By Design/RoHS Compliant (Note 1) • "Green" Device (Note 2) Mechanical Data • Case: SOT-363 • Case Material: Molded Plastic. "Green Molding" Compound. UL Flammability Classification Rating 94V-0 • Moisture Sensitivity: Level 1 per J-STD-020C • Terminal Connections: See Fig. 2 • Terminals: Finish - Matte Tin annealed over Alloy 42 leadframe. Solderable per MIL-STD-202, Method 208 • Marking & Type Code Information: See Page 5 • Ordering Information: See Page 5 • Weight: 0.015 grams (approximate) Fig. 1: SOT-363 R1 47k EQ1 EQ2 BQ2 CQ2 BQ1 CQ1 Q1 DDC144T_DIE Q2 R2 47k DDC144T_DIE Fig. 2: Schematic and Pin Configuration Sub-Component P/N Reference Device Type R1 (NOM) R2 (NOM) Figure DDTC144T_DIE Q1 NPN 47K Ω ⎯ 2 DDTC144T_DIE Q2 NPN ⎯ 47K Ω 2 Maximum Ratings: Total Device @TA = 25°C unless otherwise specified Characteristic Symbol Value Unit Power Dissipation Pd 200 mW Power Deration above 25 °C Pder 1.6 mW / °C Output Current Iout 100 mA Thermal Characteristics Characteristic Symbol Value Unit Junction Operation and Storage Temperature Range TJ, TSTG -55 to +150 °C Thermal Resistance, junction to ambient (packaged device) (Ref: equivalent to only one heated junction) @ TA = 25°C RθJA 625 °C/W Notes: 1.
