LESHAN RADIO COMPANY, LTD. Dual General Purpose Transistors The LMBT3946DW1T1 device is a spin–off of our popular SOT–23/SOT–323 three–leaded device. It is designed for general purpose amplifier applications and is housed in the SOT–363 six–leaded surface mount package. By putting two discrete devices in one package, this device is ideal for low–power surface mount applications where board space is at a premium. • hFE, 100–300 • Low VCE(sat), < 0.4 V • Simplifies Circuit Design • Reduces Board Space • Reduces Component Count • Available in 8 mm, 7–inch/3,000 Unit Tape and Reel • Device Marking: LMBT3946DW1T1 = 46 MAXIMUM RATINGS Rating Collector-Emitter Voltage (NPN) (PNP) Collector-Base Voltage (NPN) (PNP) Emitter-Base Voltage (NPN) (PNP) Collector Current-Continuous (NPN) (PNP) Electrostatic Discharge Symbol V CEO Unit Vdc 40 -40 V V EBO 4 1 2 3 SOT-363/SC-88 3 2 1 Q1 Q2 6 5 LMBT3946DW1T1* *Q1 PNP Q2 NPN Vdc 6.0 -5.0 IC TJ,Ts t g 5 4 60 -40 ESD 6 Vdc CBO THERMAL CHARACTERISTICS Characteristic Symbol (1) Total Package Dissipation PD T A = 25°C Thermal Resistance Junction RθJA to Ambient Junction and Storage Value LMBT3946DW1T1 ORDERING INFORMATION Device Package Shipping mAdc 200 -200 HBM>16000, MM>2000 LMBT3946DW1T1 SOT-363 3000Units/Reel V Max 150 Unit mW 833 °C/W –55 to +150 °C Temperature Range 1.
