DTA015EEBTL

Overview

The DTA015EEBTL is a pre-biased PNP digital transistor manufactured by ROHM Semiconductor. It integrates a single bipolar junction transistor with built-in bias resistors in an EMT3F (SOT-416FL) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features a minimum DC current gain (hFE) of 80, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. It operates within a temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• Integrates a PNP transistor with built-in bias resistors to simplify circuit design
• Eliminates the need for external input resistors in inverter configurations
• Provides high-speed switching capabilities suitable for digital logic applications

Applications

• Inverter circuits for digital logic interfaces
• Driver circuits for relays and solenoids
• Switching applications in consumer electronics

Procurement Notes

Verify the specific suffix 'BTL' corresponds to the tape-and-reel packaging format as indicated in official documentation. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the ordering quantity aligns with the manufacturer's standard reel size of 3000 units if bulk procurement is intended. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required. The EMT3F package offers a small footprint suitable for space-constrained designs. Consider the -50 V voltage rating and -100 mA current capacity to ensure adequate headroom for the application. Verify that the 250 MHz transition frequency meets the switching speed requirements of the system.

Part Context

The DTA015EEBTL belongs to ROHM's DTA series of pre-biased transistors. This series combines NPN and PNP types with various resistor ratios to provide standardized solutions for digital switching. The 'EE' designation typically indicates a specific internal resistor configuration, while 'BTL' denotes the taping packaging method. These components are designed to replace discrete transistor-resistor networks, reducing board space and assembly complexity.

Replacement Considerations

Compatible substitutes include other PNP digital transistors from ROHM such as the DTA015TEBTL or DTC015EEBTL (NPN complement). Ensure any replacement matches the EMT3F/SOT-416FL package dimensions and maintains equivalent electrical ratings for voltage, current, and gain.
