DTA115EE-TP

Overview

The DTA115EE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN transistor with built-in biasing resistors in an SOT-523-3 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a peak DC collector current of -100 mA. The device features a typical input resistance of 100 kOhms with a resistor ratio of 1. It operates within a temperature range of -55°C to +150°C, has a power dissipation rating of 150 mW, and supports a maximum operating frequency of 250 MHz.

Feature Summary

• Integrates a PNP transistor with dual internal biasing resistors for simplified circuit design.
• Utilizes the compact SOT-523-3 surface-mount package for space-constrained applications.
• Provides high switching speed capabilities suitable for high-frequency signal processing.

Applications

• General-purpose switching circuits requiring pre-biased PNP transistors.
• High-frequency signal processing applications up to 250 MHz.
• Battery-powered devices utilizing low-power surface-mount components.

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary by distributor region. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the SOT-523-3 footprint matches the target PCB layout requirements. Cross-reference the part number with the latest datasheet to confirm pinout compatibility with existing designs.

Selection Notes

Select the DTA115EE-TP when a PNP digital transistor with a 100 kOhm base resistor is required in a small outline package. Compare the 150 mW power dissipation limit against thermal constraints in the final assembly. Consider the -50 V collector-emitter voltage rating relative to the system supply voltage. Evaluate the 250 MHz frequency response against the application's signal speed requirements.

Part Context

This component belongs to the DTA series of digital transistors from Micro Commercial Components. It is functionally similar to other PNP variants in the family but distinguished by its specific 100 kOhm resistor configuration and SOT-523-3 packaging. The 'TP' suffix typically denotes tape and reel packaging options available from distributors.

Replacement Considerations

Potential substitutes include other PNP digital transistors with identical 100 kOhm resistor ratios and SOT-523-3 footprints. Verify pinout compatibility and electrical ratings such as VCEO and IC before substitution. Equivalent parts from other manufacturers must meet the same 250 MHz frequency and -50 V voltage specifications.
