Overview
The DTC143ZEBHZGTL is an NPN digital transistor from the ROHM DTC143Z series, featuring built-in bias resistors. It operates with a supply voltage of 50V and a maximum collector current of 100mA. The device integrates an input resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 47kΩ, yielding a typical resistance ratio of 10. Key electrical parameters include a DC current gain (GI) of 80 at 10mA output, a transition frequency (fT) of 250MHz, and a power dissipation rating of 150mW. It is housed in an SOT-416FL package.
Feature Summary
- Built-in bias resistors eliminate the need for external input components, simplifying circuit design.
- Enables direct configuration of inverter circuits by requiring only on/off signal conditions.
- Provides high-speed switching capabilities suitable for interface and driver applications.
Applications
- Inverter circuits
- Interface logic
- Driver stages
Procurement Notes
Verify the specific suffix 'HZGTL' against the official datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering code matches the required tape-and-reel quantity and marking specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Verify that the 50V supply voltage and 100mA current limits align with the target application's operational requirements and thermal constraints.
Part Context
This part belongs to the DTC143Z series of Bias Resistor Built-in Transistors (BRBTs). It serves as the NPN counterpart to the DTA143Z PNP series. The device is designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity in standard electronic equipment.
Replacement Considerations
Direct replacements within the same series include DTC143ZE3 and DTC143ZM, though package differences exist. Cross-package equivalents like DTC143ZU3 or DTC143ZKA offer similar electrical characteristics but require verification of pinout compatibility and thermal performance in the existing footprint.
