DTA015TEBTL

Overview

The DTA015TEBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring an integrated base bias resistor (R1) within the EMT3F (SOT-416FL) surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a single 100 kOhm input resistor, eliminating the need for external components in basic switching applications. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 5 mA and 10 V, a saturation voltage of 250 mV max at 250 µA base current, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW.

Feature Summary

• Integrates a 100 kOhm base resistor to simplify circuit design and reduce component count
• Provides high-speed switching capability with a 250 MHz transition frequency
• Offers low saturation voltage for efficient power handling in logic interfaces

Applications

• General-purpose logic level shifting and interface circuits
• Driver stages for relays, solenoids, or small motors
• Inverter and buffer circuits in digital logic systems

Procurement Notes

Verify the specific suffix 'BTL' corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the EMT3F footprint matches the target PCB layout dimensions. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a PNP pre-biased transistor with a 100 kOhm base resistor is required. Compare against alternatives like the DTA014 series if different resistance values or NPN polarity are needed. Consider the 100 mA current limit and 50 V voltage rating to ensure adequate headroom for the specific load conditions.

Part Context

This part belongs to Rohm's DTA015 series of digital transistors, which are designed to replace discrete BJT and resistor combinations. The EMT3F package provides a compact solution for space-constrained designs. It serves as a direct replacement for older SOT-416FL equivalents in existing schematics.

Replacement Considerations

Check pinout compatibility with legacy SOT-416 devices. Verify that substitute parts maintain the same 100 kOhm internal resistance value to preserve timing and drive characteristics.
