DTC144EEBTL

Overview

The DTC144EEBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in a single configuration. It utilizes the SOT-416FL (EMT3F) surface-mount package. Key electrical parameters include a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device incorporates typical input and emitter-base resistors of 47 kOhms each, with a resistance ratio of 1. It offers a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The maximum operating temperature reaches +150°C.

Feature Summary

• Integrates dual bias resistors to simplify circuit design by eliminating external components for inverter configurations.
• Provides high-speed switching capabilities suitable for interface and driver applications through a 250 MHz transition frequency.
• Features a compact SOT-416FL surface-mount package designed for automated assembly and space-constrained layouts.

Applications

• Inverter circuits requiring simplified input stages
• Interface logic level shifting between microcontrollers and peripherals
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix 'BTL' against the manufacturer's latest datasheet to confirm packaging details such as reel size or tape specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as standard electronic components may experience supply fluctuations.

Selection Notes

Select this component when a single NPN digital transistor with equal bias resistors (R1=R2=47kΩ) is required. It is appropriate for designs needing a 50V collector-emitter breakdown voltage and 100mA current handling. Consider the SOT-416FL package dimensions for PCB layout constraints. Verify that the 150mW power dissipation limit aligns with the thermal management strategy of the final application.

Part Context

This part belongs to the DTC144 series of digital transistors from ROHM Semiconductor. The series includes complementary PNP types like the DTA144EEBTL and variants with different resistor values or automotive qualifications. The DTC144EEBTL represents the standard commercial-grade NPN option within this family, distinguished by its specific resistor network and package type.

Replacement Considerations

Direct substitutes include the DTC144EETL (standard SOT-416 package) or DTC144EE3HZGTL (automotive grade). Verify pinout compatibility and electrical parameter tolerances before substitution. Ensure the replacement package matches the footprint if using the SOT-416FL variant.
