Overview
The DTC124ECAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with typical values of R1 = 22 kOhms and R2 = 22 kOhms, yielding a resistor ratio of 2.1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a transition frequency of 250 MHz, and a power dissipation rating of 350 mW. The emitter-base voltage (VEBO) is rated at 2.5 V.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
- Enables straightforward configuration of inverter circuits where only on/off conditions require setting.
Applications
- Inverter circuits
- Driver circuits
- Switching applications
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm RoHS compliance status and specific packaging options such as cut tape or reel configurations prior to procurement. Ensure that the ordering suffix matches the required taping specifications for automated assembly processes.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Verify that the 50 V collector-emitter voltage and 100 mA current ratings align with the target application's load requirements. Consider the SOT-23-3 footprint compatibility during PCB layout planning.
Part Context
This part belongs to the DTx series of digital transistors from ROHM Semiconductor. It serves as the NPN counterpart to the PNP DTA124ECA model. The series is designed for general-purpose switching and logic interface applications requiring simplified biasing networks.
Replacement Considerations
The DTA124ECA is documented as the complementary PNP type within the same product family. Cross-referencing with other manufacturers requires verifying equivalent voltage, current, and internal resistance ratios.
