CYStech Electronics Corp. Spec. No. : C274S3 Issued Date : 2002.06.01 Revised Date : 2002. 11.02 Page No. : 1/3 General Purpose PNP Digital Transistors (Built-in Resistors) DTA144TS3 Features • Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). • The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. • Only the on/off conditions need to be set for operation, making device design easy. • Complements the DTC144TS3 Equivalent Circuit DTA144TS3 SOT-323 R1=47 kΩ B：Base C：Collector E：Emitter Absolute Maximum Ratings (Ta=25°C) Parameter Symbol Limits Unit Collector-Base Voltage Collector-Emitter Voltage Emitter-Base Voltage Collector Current Power Dissipation Junction Temperature Storage Temperature VCBO VCEO VEBO IC Pd Tj Tstg -50 -50 -5 -100 200 150 -55~+150 V V V mA mW °C °C DTA144TS3 CYStek Product Specification Spec.
