Overview
The DTC124XCAHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates biasing resistors with typical values of R1 at 22 kOhms and R2 at 47 kOhms, yielding a resistor ratio of 2.1. 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 VCEO of 300 mV, VEBO of 2.5 V, and power dissipation of 350 mW. It meets AEC-Q101 automotive qualification standards and functions within a temperature range up to +150 C.
Feature Summary
- Integrates thin-film biasing resistors to simplify circuit design by eliminating external input components.
- Features complete isolation between bias resistors to allow negative input biasing and eliminate parasitic effects.
- Qualified for automotive applications under the AEC-Q101 standard for high reliability.
Applications
- Inverter circuits
- Interface logic driving
- General-purpose driver stages
Procurement Notes
Verify the specific suffix GT116 against official ROHM documentation to confirm reel packaging and tape specifications. Ensure the component matches the required automotive grade (AEC-Q101) if used in vehicle systems. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The SOT-23-3 package suits automated surface-mount assembly. Consider the 22 kOhm input resistance value for appropriate base drive requirements. Verify that the 300 mV VCEO rating aligns with the specific load voltage conditions of the target application circuit.
Part Context
This part belongs to the ROHM DTx series of pre-biased transistors. The DTC124X variant specifically denotes an NPN configuration with a 22 kOhm input resistor. The CAHZG suffix indicates the automotive-grade version packaged in SOT-23. This series is designed to replace discrete resistor-transistor combinations in switching applications.
Replacement Considerations
The DTC124XCAHZG is listed as a part number alias for this component. For pin-compatible alternatives, verify other ROHM DTC124 variants such as DTC124TCAT116, ensuring the voltage ratings and resistor values match the original design requirements.
