Overview
The DTC044EEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors in an SMD/SMT EMT3F (SOT-416FL) package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes typical input resistance values of 47 kOhms for both R1 and R2, maintaining a resistor ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 150 mW. The emitter-base voltage is specified at 3 V, with a maximum operating temperature of +150 C.
Feature Summary
- Integrates NPN bipolar junction transistor with dual biasing resistors to simplify circuit design.
- Utilizes compact surface-mount EMT3F packaging for efficient board space utilization.
- Supports high-speed switching applications with a transition frequency up to 250 MHz.
Applications
- Interface circuits requiring level shifting or signal buffering.
- Driver stages for low-power loads and logic interfaces.
- General-purpose switching applications in consumer electronics.
Procurement Notes
Verify the specific suffix 'TL' corresponds to the tape-and-reel packaging configuration as indicated by distributor listings. Confirm RoHS compliance status through official datasheets prior to integration. Ensure the ordering quantity aligns with standard factory pack sizes, typically 3000 units per reel, to match manufacturing requirements.
Selection Notes
Select this component when a single NPN digital transistor with equal biasing resistors (R1=R2=47kΩ) is required. It is suitable for designs needing a 50V collector-emitter breakdown and 100mA current handling. Consider the 150mW power dissipation limit and SOT-416FL footprint constraints during PCB layout planning.
Part Context
This part belongs to the DTC044EEB series of digital transistors from ROHM Semiconductor. These components are classified as standard-grade devices intended for general electronic equipment. They are explicitly noted as not recommended for use in automotive applications, distinguishing them from higher-reliability automotive-grade counterparts in the manufacturer's portfolio.
Replacement Considerations
Direct substitutes within the same family include DTC044EEBTLDKR and DTC044EEBTLCT, which share identical electrical characteristics but differ in packaging format such as cut-tape or Digi-Reel options. Cross-package replacements require verification of pin compatibility and thermal performance.
