Overview
The DTA114TCAT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance of 10 kOhms and achieves a minimum DC current gain (hfe) of 100 at -1 mA and -5 V. It supports a maximum operating frequency of 250 MHz with a power dissipation rating of 350 mW and operates up to +150°C.
Feature Summary
- Integrates built-in biasing resistors to enable inverter circuit configuration without external input components.
- Simplifies operation by requiring only on/off condition settings for the user interface.
Applications
- Inverter circuits
- Driver circuits
- Logic level translation
Procurement Notes
Verify the specific suffix 'T116' against the manufacturer's official datasheet to confirm tape-and-reel packaging details and RoHS compliance status. Ensure the component meets AEC-Q101 requirements if automotive qualification is necessary, as standard versions may differ from qualified variants.
Selection Notes
Select this PNP variant when a negative supply rail or high-side switching application is required. Compare the 10 kOhm input resistance against other DTx series parts like DTC114TCA for NPN equivalents. Verify that the 350 mW power dissipation in the SOT-23-3 package suffices for the intended thermal environment.
Part Context
This component belongs to the ROHM DTx series of digital transistors, which combine bipolar junction transistors with internal bias networks. The DTA114TCA designation indicates a PNP type with 10 kOhm input resistance, while the T116 suffix typically denotes the specific reel packaging format used by distributors.
Replacement Considerations
The DTC114TCA serves as the complementary NPN counterpart within the same series. For direct pin-compatible substitution in PNP applications, verify equivalent voltage and current ratings against other ROHM DTA114 variants or third-party equivalents with matching SOT-23-3 footprints.
