DTA044TEBTL

Overview

The DTA044TEBTL is a PNP digital transistor with built-in biasing resistors manufactured by Rohm Semiconductor. It features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 60 mA. The device incorporates a single base resistor (R1) with a nominal value of 47 kOhms. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 5 mA and 10 V, and a saturation voltage of 150 mV at 500 µA base current and 5 mA collector current. The transition frequency is specified at 250 MHz, with a maximum power dissipation of 150 mW.

Feature Summary

• Integrates a single biasing resistor to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities suitable for digital logic applications.
• Utilizes a compact surface-mount package for efficient board space utilization.

Applications

• General-purpose digital switching circuits
• Interface between logic gates and loads
• Level shifting in low-voltage systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant selection. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement. Ensure storage conditions adhere to the specified temperature ranges to maintain device integrity.

Selection Notes

Select this component when a PNP configuration with a 47 kOhm base resistor is required. Verify that the 50 V voltage rating and 60 mA current capacity meet the load requirements. Consider the EMT3F package dimensions for PCB layout compatibility and thermal management needs within the 150 mW dissipation limit.

Part Context

This part belongs to the DTA044 series of pre-biased transistors from Rohm. It is designed as a replacement for discrete resistor-transistor networks, offering improved reliability and reduced assembly time. The series is widely used in consumer electronics and industrial control panels where space constraints are critical.

Replacement Considerations

Check for direct pin-compatible alternatives such as the DTA044EE or similar PNP digital transistors with identical 47 kOhm resistance values. Ensure substitute parts match the 50 V rating and SOT-416FL package footprint before integration into existing designs.
