Overview
The DTA123YETL is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an EMT3 (SOT-416) surface-mount package. It integrates bias resistors R1 (2.2 kΩ) and R2 (10 kΩ) to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation of 150 mW. The device features a minimum DC current gain (hFE) of 33 at -10 mA and -5 V, with a transition frequency of 250 MHz. It operates within a temperature range up to +150°C.
Feature Summary
- Integrates built-in bias resistors to eliminate external input components for inverter circuits.
- Provides simplified operation by requiring only on/off condition settings.
- Designed for high-frequency switching applications with a 250 MHz transition frequency.
Applications
- Inverter circuits
- Interface drivers
- General-purpose switching
Procurement Notes
Verify the specific suffix 'ETL' against the manufacturer's official datasheet to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with the EMT3/SOT-416 footprint during PCB layout. Confirm RoHS compliance status through the latest product documentation before procurement.
Selection Notes
Select this component for designs requiring a PNP digital transistor with a 2.2 kΩ base resistor and 10 kΩ emitter-base resistor. It is suitable for space-constrained applications due to the small EMT3 package. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements of the target application.
Part Context
The DTA123YETL belongs to the DTA123YE series of digital transistors from ROHM Semiconductor. These devices are standard-grade products designed for general electronic equipment. They are distinct from automotive-grade variants like the DTA123JUBHZGTL, which carry AEC-Q101 certification. This series focuses on cost-effective integration of biasing networks.
Replacement Considerations
Direct substitutes may include other PNP digital transistors with similar resistor ratios and packages, such as the DTA123JE3. However, verify pinout compatibility and exact resistance values (R1=2.2kΩ, R2=10kΩ) when replacing. Automotive applications require AEC-Q101 certified alternatives.
