DTA144EE3HZGTL

Overview

The DTA144EE3HZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SOT-416 (EMT3) surface-mount package. It operates with a supply voltage of -50 V and a continuous collector current of -0.1 A. The device includes two internal resistors, R1 and R2, both typically valued at 47 kOhms, configured in a potential divider arrangement. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. It supports an operating temperature range from -55°C to +150°C and complies with AEC-Q101 automotive standards.

Feature Summary

• Integrates dual bias resistors (R1=R2=47kΩ) to simplify circuit design by eliminating external components for inverter configurations.
• Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation up to 150°C.
• Compact SOT-416 (EMT3) package enables efficient space utilization in dense surface-mount applications.

Applications

• Inverter circuits requiring simplified input biasing without external resistors.
• Interface logic level shifting between microcontrollers and peripheral devices.
• Driver stages for low-current switching applications in automotive electronics.

Procurement Notes

Verify the complete part number including suffixes such as 'HZGTL' to ensure correct packaging and automotive qualification. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Check for obsolescence notices, as some variants may be marked not recommended for new designs while others remain active. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage during reflow soldering.

Selection Notes

Select this component when a PNP digital transistor with equal bias resistors is required for automotive or industrial environments. Compare against NPN counterparts like DTC144EE3HZGTL if polarity requirements differ. Verify that the 47 kOhm resistor values align with the target input impedance and drive strength needs. Consider the SOT-416 footprint constraints relative to available PCB real estate and thermal management capabilities.

Part Context

This part belongs to ROHM's DTA144 series of digital transistors, which are designed for general-purpose switching and logic inversion. The series offers complementary NPN options and various packaging formats. The HZG suffix indicates automotive grade qualification, distinguishing it from standard commercial grades. It serves as a direct replacement for legacy discrete resistor-transistor networks in compact designs.

Replacement Considerations

DTA144EU3HZGT is a pin-compatible alternative within the same series. Verify package dimensions and electrical parameters match before substitution. Ensure the substitute maintains AEC-Q101 certification if automotive use is required.
