Overview
The DTC143XETL is an NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SOT-416 surface-mount package. This Bias Resistor Built-in Transistor (BRBT) integrates a base resistor (R1) and an emitter-base resistor (R2) with a ratio of approximately 2:1. It features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device includes a 4.7 kOhm input resistor and offers a minimum DC current gain (hFE) of 30 at IC=10 mA and VCE=5 V. With a transition frequency (fT) of 250 MHz and a power dissipation rating of 150 mW, it supports operation up to a junction temperature of +150°C.
Feature Summary
- Integrates dual bias resistors (R1 and R2) to simplify circuit design and reduce component count.
- Provides high-speed switching capability suitable for interface and driver applications.
- Designed for automotive reliability with AEC-Q101 qualification.
Applications
- Automotive inverter control circuits
- Interface drivers for logic level shifting
- General-purpose digital switching
Procurement Notes
Verify the specific suffix 'ETL' against the manufacturer's latest datasheet to confirm packaging details and availability status. Ensure the selected variant matches the required resistance ratio and thermal specifications for the target application environment.
Selection Notes
Select this component when a compact NPN digital transistor with integrated dual resistors is required for space-constrained designs. Verify that the 50 V voltage rating and 100 mA current capacity meet the load requirements. Confirm compatibility with SOT-416 footprint constraints during PCB layout.
Part Context
This part belongs to the ROHM DTC143 series of NPN digital transistors. The series offers various packages and resistance configurations to suit different power and size requirements. The DTC143XETL specifically utilizes the SOT-416 package, providing a balance between thermal performance and small form factor.
Replacement Considerations
Cross-reference with other ROHM parts in the DTC143 family sharing the SOT-416 package and similar electrical characteristics. Verify pinout compatibility and resistance values before substitution.
