Overview
The DTA114EUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in a UMT3 (SOT-323) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features an input resistance (R1) of 10 kΩ and an emitter-base resistance (R2) of 10 kΩ. It operates with a maximum power dissipation of 200 mW and supports a maximum operating temperature of +150°C. The DC current gain (hFE) is specified at a minimum of 30 under standard test conditions.
Feature Summary
- Integrates built-in bias resistors to eliminate external resistor requirements for inverter circuits.
- Designed for surface-mount assembly within compact UMT3 packages.
- Supports high-temperature operation up to 150°C.
Applications
- Inverter circuits requiring simplified input stages.
- General-purpose switching applications in consumer electronics.
- Driver circuits for low-current loads.
Procurement Notes
Verify the specific suffix AT106 against official ROHM documentation to confirm tape-and-reel packaging details and RoHS compliance status. Ensure the component meets the required AEC-Q101 automotive qualification if intended for vehicle systems, as standard variants may lack this certification. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times.
Selection Notes
Select this component when a PNP digital transistor with equal R1 and R2 values (10kΩ) is required. Compare hFE specifications against load requirements to ensure adequate drive capability. Verify that the SOT-323 footprint matches the PCB layout constraints. Consider thermal management capabilities given the 200mW power dissipation limit in enclosed spaces.
Part Context
This part belongs to the DTA114 series of pre-biased transistors from ROHM. It shares pinout compatibility with other devices in the family but differs in internal resistor ratios and polarity. The UMT3 package is common across multiple ROHM digital transistor lines, facilitating board space optimization in portable devices.
Replacement Considerations
DTA114EU3HZGT106 offers similar pinout and package characteristics. Verify resistor values and hFE ranges before substitution. Ensure the replacement part meets the same voltage and current ratings for direct interchangeability in existing designs.
