Overview
The DTC124ECAHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 (SST3) surface-mount package. It integrates bias resistors with typical values of R1=22 kΩ and R2=22 kΩ, yielding a resistor ratio of 2.1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (PD) of 350 mW. The device features a minimum DC current gain (hFE) of 56 at IC=5 mA and VCE=5 V, with a transition frequency (fT) of 250 MHz. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
- Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation up to 150°C.
- High-speed switching capability supported by a 250 MHz transition frequency.
Applications
- Inverter circuits
- Interface drivers
- General-purpose switching applications
Procurement Notes
Verify the complete part number including the suffix GT116 to ensure correct tape-and-reel packaging configuration. Confirm that the specific revision matches the required datasheet version for accurate parameter validation. Check RoHS compliance status as indicated in the official documentation before finalizing procurement specifications.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Ensure the 50 V collector-emitter voltage rating exceeds the maximum operating voltage of the target application. Verify that the 100 mA continuous current limit accommodates the load requirements without exceeding the 350 mW power dissipation threshold.
Part Context
This part belongs to the DTC124 series of pre-biased transistors from ROHM Semiconductor. The ECAHZG suffix indicates the specific resistor values and package type, while GT116 denotes the reel quantity and taping specification. It is functionally related to other variants in the DTC12x family but distinguished by its specific resistance ratios and automotive qualification.
Replacement Considerations
Direct substitutes may include DTC124XCAHZGT116 or DTC124TCAT116, provided their respective resistor values and voltage ratings align with the original design constraints. Verify pinout compatibility and thermal characteristics before substitution.
