DTA124EE-TP

Overview

The DTA124EE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-523 surface-mount package. It integrates built-in bias resistors, specifically R1 and R2 with a typical value of 22 kOhms each and a resistance ratio of 1. The device supports a maximum supply voltage (VCC) of -50 V and a continuous collector current (IC) of -100 mA. Key electrical parameters include a DC current gain (GI) minimum of 56, a transition frequency (fT) of 250 MHz, and a power dissipation (PD) rating of 150 mW at 25°C. The component operates within a junction temperature range up to 150°C and features lead-free finish compliant with RoHS standards.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without external input components.
• Complete isolation of bias resistors allows for negative biasing of the input while eliminating parasitic effects.
• Halogen-free 'Green' construction with epoxy meeting UL 94 V-0 flammability ratings.

Applications

• Inverter circuits requiring simplified design through integrated biasing.
• Switching applications where only on/off conditions need to be set.
• High-frequency signal processing utilizing the 250 MHz transition frequency.

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors listed on their official website. MCC provides full traceability and quality assurance only for parts sourced through these channels. Products obtained from unauthorized sources lack warranty coverage and assistance. Ensure compliance with RoHS requirements by confirming the presence of the "TP" suffix designation in the ordering information.

Selection Notes

Select the DTA124EE-TP when a PNP digital transistor with integrated 22 kOhm bias resistors is required in a compact SOT-523 footprint. This component is suitable for designs needing a transition frequency of 250 MHz and a maximum collector current of 100 mA. Consider the 150 mW power dissipation limit and the -50 V supply voltage rating during thermal and electrical planning. Verify that the specific application does not involve life support devices without express written approval.

Part Context

The DTA124EE-TP belongs to the DTA124EE series of PNP digital transistors produced by Micro Commercial Components. It is part of a family of pre-biased transistors designed to simplify circuit layouts by replacing discrete resistor networks. The device utilizes a standard SOT-523 package, which is common in space-constrained surface-mount applications. The "TP" suffix indicates a tape-and-reel packaging format containing 3,000 pieces per reel.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure compatibility with the SOT-523 package, PNP polarity, 22 kOhm internal resistance values, and -50 V maximum voltage rating.
