DTA144EEBHZGTL

Overview

DTA144EEBHZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SMD/SMT configuration. It utilizes the EMT3F (SOT-416FL) package with three terminals. Key electrical parameters include a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device incorporates internal resistors R1 and R2, both typically valued at 47 kOhms, providing a resistor ratio of 1. It exhibits a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, with a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, and it supports operating temperatures up to +150°C.

Feature Summary

• Integrates dual bias resistors (R1=R2=47kΩ) to simplify circuit design by eliminating external components.
• Provides high-speed switching capabilities suitable for interface and driver applications via a 250 MHz transition frequency.
• Offers robust thermal performance with a maximum junction temperature rating of +150°C.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as cut tape or reel quantities. Ensure the ordering suffix matches the required tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this PNP variant when complementary NPN types like DTC144EE are insufficient for the required polarity. Verify that the 47 kOhm internal resistance values align with the target input impedance requirements. Ensure the -50 V voltage rating exceeds the maximum circuit supply voltage to prevent breakdown during operation.

Part Context

This component belongs to the DTA144 series of digital transistors from ROHM Semiconductor. It serves as the PNP counterpart to the NPN DTC144EE model. The series is designed for compact surface-mount applications where space efficiency and simplified biasing networks are critical design constraints.

Replacement Considerations

The DTA144EUAFRA is listed as a similar level replacement with the same pinout and package, though it is marked as not recommended for new designs. Verify compatibility with the DTA144EE3HZGTL if automotive grade requirements apply, noting potential differences in qualification standards.
