Overview
The DTD123TCHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates a 2.2 kOhm input resistor to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 40 V and a continuous collector current of 500 mA. The device features a minimum DC current gain (hFE) of 100 at 50 mA and 5 V, with a transition frequency of 200 MHz. Power dissipation is rated at 200 mW, and the maximum operating temperature reaches +150 C. It holds AEC-Q101 qualification for automotive applications.
Feature Summary
- Integrates built-in biasing resistors to enable inverter circuit configuration without external input components.
- AEC-Q101 qualified for high reliability in automotive environments.
- Supports surface mount installation in compact SOT-23-3 packaging.
Applications
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements prior to integration. Ensure the selected variant matches the required input resistance value and polarity for the target application design.
Selection Notes
Select this component when a single NPN digital transistor with a 2.2 kOhm base resistor is required for 40 V, 500 mA applications. Consider the 200 MHz transition frequency for switching speed requirements. Verify that the SOT-23-3 package size and 200 mW power dissipation rating fit the thermal and spatial constraints of the design.
Part Context
This part belongs to the ROHM DTD series of pre-biased transistors designed to replace discrete resistor-transistor combinations. The 'T116' suffix typically denotes the specific taping and reel packaging format used for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other NPN digital transistors featuring similar 2.2 kOhm input resistance and 40 V/500 mA ratings if substitution is necessary.
