DTA113ZE-TP

Overview

The DTA113ZE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-523 surface-mount package. It integrates internal biasing resistors to simplify circuit design. Key electrical parameters include a maximum supply voltage (Vcc) of -50 V, a collector current (Ic) of -100 mA, and power dissipation (Pd) of 150 mW. The device features an input resistance (R1) of 1.0 kΩ with a tolerance range of 0.7–1.3 kΩ, and a resistance ratio (R2/R1) of 10. Transition frequency (fT) is specified at 200 MHz. Operating temperatures range from -55°C to +150°C.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct channels. Ensure ordering suffixes match specific packaging requirements such as tape and reel quantities. Confirm compliance with environmental regulations like RoHS and REACH before procurement. Check datasheet revisions for any updates to mechanical dimensions or electrical characteristics prior to finalizing orders.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required. The SOT-523 package suits space-constrained designs. Verify that the -50 V supply voltage and -100 mA current limits meet application demands. Consider the 1.0 kΩ input resistance for base drive calculations. Ensure thermal management supports the 150 mW power dissipation limit within the operating temperature range.

Part Context

This part belongs to the DTA113 series of pre-biased transistors from Micro Commercial Components. It is designed as a replacement for discrete resistor-transistor networks, reducing board space and assembly time. The 'ZE' suffix indicates the specific pinout and resistor values for the SOT-523 package variant.

Replacement Considerations

Check for compatible PNP digital transistors in the SOT-523 package with similar R1 values (approx. 1kΩ) and Vceo ratings (-50V). Verify pin compatibility (Base, Emitter, Collector) against the schematic. Ensure equivalent transition frequency and power dissipation capabilities are maintained.
