Overview
The DTA123JEFRATL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an internal base resistor (R1) of 2.2kΩ and an emitter-base resistor (R2) of 47kΩ. Packaged in the SOT-323 (UMT3) surface-mount format, it offers a power dissipation rating of 150mW and a DC current gain (hFE) of at least 80 at specified test conditions. The component supports a maximum operating temperature of +150°C.
Feature Summary
- Integrates biasing resistors internally to eliminate external input components for inverter circuits
- Provides simplified operation requiring only on/off condition settings for easy circuit design
- Utilizes compact SOT-323 surface-mount packaging to reduce board space
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific suffix FRATL against official ROHM documentation to confirm reel quantity and tape specifications. Ensure compatibility with standard SMT assembly processes for the UMT3 package. Cross-reference the part number with authorized distributors to confirm current supply status and RoHS compliance details before procurement.
Selection Notes
Select this component when a PNP digital transistor with 50V rating and 100mA current capacity is required. The fixed 2.2kΩ base resistor suits applications needing moderate drive currents. Consider the SOT-323 footprint constraints and thermal dissipation limits relative to the application environment. Verify if the specific resistor ratio meets the logic interface requirements.
Part Context
This part belongs to the DTA123JKA series of digital transistors from ROHM. It shares functional similarities with other members like DTA123JKAT146 but differs in packaging and specific suffix designations. The series is designed for general-purpose switching and logic interfacing tasks where space-saving and simplified biasing are priorities.
Replacement Considerations
DTA123JUAFRA is listed as a similar level replacement with the same pinout and package, though it is not recommended for new designs. Other single PNP digital transistors with comparable 50V/100mA ratings may serve as alternatives if resistor values align with the design needs.
