DTC144EE3HZGTL

Overview

The DTC144EE3HZGTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in a potential divider configuration where R1 equals R2. It is housed in a compact SOT-416 (EMT3) surface-mount package with three terminals. The device supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a maximum power dissipation of 150 mW. Key electrical parameters include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a typical input resistance of 47 kOhms, and a transition frequency of 250 MHz. It operates within a temperature range up 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.
• Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation.
• Compact SOT-416 package enables efficient space utilization on printed circuit boards.

Applications

• Inverter circuits requiring simplified input biasing without external resistors.
• Automotive electronic systems demanding high reliability and thermal stability.
• General-purpose switching applications in consumer electronics and industrial equipment.

Procurement Notes

Verify the specific suffix 'HZGTL' against the manufacturer's latest datasheet to confirm packaging details and RoHS compliance status. Ensure that the AEC-Q101 qualification aligns with your project's automotive grade requirements. Cross-reference the part number with official ROHM documentation to avoid confusion with similar variants like DTC144EEBHZGTL, which may have different availability or pinout nuances.

Selection Notes

Select this component when a single NPN digital transistor with equal bias resistors is required for space-constrained designs. The 47 kOhm resistor ratio suits standard logic interface applications. Consider the 50 V rating and 100 mA current capacity for low-power switching tasks. Verify thermal management needs given the 150 mW dissipation limit in the small SOT-416 package.

Part Context

This part belongs to the DTC144 series of digital transistors from ROHM, designed for replacing discrete resistor-transistor combinations. The 'EE3' designation typically indicates the specific resistor value and package type within the family. It serves as a direct replacement for older discrete configurations, offering improved consistency and reduced board space compared to separate components.

Replacement Considerations

DTA144EE3HZG is the complementary PNP version. For equivalent NPN performance in different packages, consider DTC144EETL (SOT-416) or DTC144EUBTL (SOT-323FL). Verify pin compatibility and electrical ratings before substitution.
