Overview
DTA124TU3T106 is a PNP digital transistor from ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with typical values of R1 = 22 kΩ and R2 = 47 kΩ. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (Ic) of -100 mA. Key electrical parameters include a DC current gain (hFE) minimum of 68 at Ic = 5 mA and Vce = -5 V, a transition frequency (fT) of 250 MHz, and a power dissipation (Pd) of 200 mW.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input resistors.
- Enables straightforward configuration of inverter circuits through simple on/off control conditions.
- Provides high-speed switching capabilities suitable for digital logic applications.
Applications
- Inverter circuits
- Digital logic interfaces
- General-purpose switching applications
Procurement Notes
Verify the specific suffix TU3T106 against official ROHM documentation to confirm the exact tape-and-reel quantity and packaging format. Ensure compatibility with standard SMT assembly processes for the SOT-323 footprint. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a PNP digital transistor with a 22 kΩ base resistor is required in a compact SOT-323 package. Verify that the -50 V collector-emitter voltage rating meets the system's maximum operating voltage requirements. Confirm that the 200 mW power dissipation capability is sufficient for the intended thermal environment and duty cycle.
Part Context
This part belongs to the DTA124X series of pre-biased PNP transistors manufactured by ROHM Semiconductor. The series is designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The DTA124TU3T106 specifically utilizes the UMT3 (SOT-323) package, which is widely used in portable electronics and compact consumer devices.
