Overview
The DTA143ZUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications. It integrates internal biasing resistors within an SOT-323 (UMT3) package to simplify circuit design. Key electrical specifications include a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features a typical base resistor value of 4.7 kOhms and achieves a transition frequency of 250 MHz. Power dissipation is rated at 200 mW, with a maximum operating temperature of +150°C.
Feature Summary
- Integrates dual biasing resistors to reduce external component count and PCB space.
- Optimized for high-speed switching operations with a 250 MHz transition frequency.
- Provides consistent DC current gain characteristics across operating temperatures.
Applications
- General-purpose switching circuits in consumer electronics.
- Driver stages for relays and small motors.
- Logic level translation between microcontrollers and peripheral devices.
Procurement Notes
Verify the specific suffix 'ZUA' against official ROHM documentation to confirm pinout compatibility and internal resistor ratios, as variations exist within the DTA143 family. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.
Selection Notes
Select this component when a compact PNP switch with integrated base resistance is required. Ensure the 4.7 kOhm input impedance aligns with the driving source capabilities. Verify that the -50 V rating exceeds the maximum circuit voltage under all transient conditions.
Part Context
This part belongs to the DTA143 series of pre-biased transistors from ROHM. The series offers various packaging options and resistor configurations to suit different density and performance requirements in portable and industrial electronic designs.
Replacement Considerations
Cross-reference with other DTA143 variants such as DTA143TUAT106 or DTA143XCAT116 only if pinout and internal resistor values are identical. Verify package compatibility and thermal characteristics before substitution.
