LDTD143ELT1G

LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network LDTD143ELT1G S-LDTD143ELT1G • Applications Inverter, Interface, Driver • Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on/off conditions need to be set for operation, making the device design easy. 3 1 2 SOT-23 • We declare that the material of product compliance with RoHS requirements. • S- Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable 1 BASE zAbsolute maximum ratings (Ta=25°C) Symbol Limits Unit Supply voltage VCC 50 V Input voltage VIN −10 to +30 V Output current IC 500 mA Power dissipation PD 200 mW Junction temperature Tj 150 °C Storage temperature Tstg −55 to +150 °C Parameter R1 3 COLLECTOR R2 2 EMITTER DEVICE MARKING AND RESISTOR VALUES Device Marking R1 (K) R2 (K) Shipping LDTD143ELT1G S-LDTD143ELT1G E6 4.7 4.7 3000/Tape & Reel LDTD143ELT3G S-LDTD143ELT3G E6 4.7 4.7 10000/Tape & Reel zElectrical characteristics (Ta=25°C) Parameter Symbol Min.
