DTC114EET1 SeriesBias Resistor TransistorNPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network This new series of digital transistors is designed to replace a single device and its external resistor bias network. The BRT (Bias Resistor Transistor) contains a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base−emitter resistor. The BRT eliminates these individual components by integrating them into a single device. The use of a BRT can reduce both system cost and board space. The device is housed in the SC−75/SOT−416 package which is designed for low power surface mount applications.Features•Simplifies Circuit Design•Reduces Board Space•Reduces Component Count•The SC−75/SOT−416 Package Can be Soldered Using Wave or Reflow•The Modified Gull−Winged Leads Absorb Thermal Stress During Soldering Eliminating the Possibility of Damage to the Die •Available in 8 mm, 7 inch/3000 Unit Tape & Reel•Pb−Free Packages are AvailableMAXIMUM RATINGS(T= 25°C unless otherwise noted)Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.THERMAL CHARACTERISTICS2.FR−4 @ 1.0 × 1.0 Inch PadNPN SILICONBIAS RESISTOR TRANSISTORSSC−75/SOT−416CASE 463STYLE 121PIN 3(OUTPUT)PIN 2EMITTER(GROUND)PIN 1BASExx= Specific Device CodeM=Date CodeMARKINGDIAGRAMSee detailed ordering, marking, and shipping information in the package dimensions section on page 2 of this data sheet.ORDERING INFORMATION†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.ELECTRICAL CHARACTERISTICS(T= 25°C unless otherwise noted)ON CHARACTERISTICS (Note 3)3.Pulse Test: Pulse Width < 300 m s, Duty Cycle < 2.0%ELECTRICAL CHARACTERISTICS (T A = 25°C unless otherwise noted) (Continued)Figure 1.
