Overview
The DTC113ZEFRATL is a single NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the EMT3 (SOT-416) package. It integrates biasing resistors with a typical input resistance of 1 kOhms and an emitter-base resistance of 10 kOhms. The device supports a collector continuous current of 100 mA and operates up to a maximum frequency of 250 MHz. Key electrical limits include a collector-emitter voltage of 50 V, power dissipation of 150 mW, and a minimum DC current gain of 33 at 5 mA/5 V. It holds AEC-Q101 automotive qualification.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design by eliminating external components
- Enables straightforward inverter configuration requiring only on/off condition settings
- Automotive-grade reliability certified under AEC-Q101 standards
Applications
- Inverter circuits for automotive systems
- General-purpose switching applications in industrial electronics
- Driver circuits for low-power loads in consumer devices
Procurement Notes
Verify the specific suffix FRATL against the official ROHM datasheet to confirm the EMT3 packaging and tape-and-reel quantity. Ensure the procurement channel provides traceability documentation required for AEC-Q101 qualified components. Cross-reference the full part number to distinguish from standard grade variants lacking automotive certification.
Selection Notes
Select this component when a compact NPN solution with integrated base and emitter resistors is required for space-constrained designs. The 1 kOhm input resistor value suits direct interface with standard logic outputs. Consider the 150 mW power dissipation limit and thermal management requirements for the small EMT3 footprint during high-frequency switching operations.
Part Context
This part belongs to the DTC113 series of pre-biased transistors from ROHM. It serves as the NPN counterpart to the PTA113ZEFRATL. The series is engineered to replace discrete resistor-transistor combinations, reducing board space and assembly complexity while maintaining consistent electrical characteristics across production batches.
Replacement Considerations
DTA113ZEFRATL is the complementary PNP type within the same family. For direct pin-compatible substitution, verify the polarity requirement. Other SOT-416 NPN digital transistors may require schematic adjustments due to differing internal resistor ratios or gain specifications.
