Overview
The DTC043EEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3F (SOT-416FL) surface-mount package. It operates with a collector-emitter breakdown voltage of 50 V and a continuous collector current of 100 mA. The device includes a base resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 4.7 kOhms, resulting in a typical resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 20 at 5 mA and 10 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. The unit supports operation up to +150°C.
Feature Summary
- Integrates dual bias resistors to simplify circuit design and reduce component count.
- Provides high-speed switching capabilities suitable for digital logic applications.
- Offers compact surface-mount packaging for space-constrained designs.
Applications
- General-purpose digital switching circuits
- Interface between microcontrollers and peripheral devices
- Level shifting and buffer stages in low-power electronics
Procurement Notes
Verify the specific suffix 'EBTL' corresponds to the EMT3F package and 4.7k/4.7k resistor configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity aligns with standard reel or cut-tape availability from authorized distributors.
Selection Notes
Select this component when a pre-biased NPN transistor with equal 4.7kOhm resistors is required. Compare against similar models like DTC043EUBTL if different packaging or resistor values are needed. Consider the 150 mW power dissipation limit and 50 V voltage rating during thermal and electrical stress analysis.
Part Context
This part belongs to the DTC043 series of digital transistors from ROHM. It shares the same internal circuit topology as other variants but differs in packaging and specific resistor tolerances. The EMT3F package is a small outline transistor format designed for automated surface-mount assembly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications before considering alternative manufacturers or ROHM family members.
