DTA114YCAT116

Overview

The DTA114YCAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and a resistor ratio of 4.7. Key electrical parameters include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 350 mW. The device features a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, with a transition frequency of 250 MHz. It operates within a temperature range up to +150°C and meets AEC-Q101 qualification standards.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating external components.
• Provides high-speed switching capabilities suitable for applications requiring fast response times.
• Features low saturation voltage to minimize power loss during conduction states.

Applications

• Driver circuits for relays and solenoids
• Inverter circuits in logic interfaces
• Switching elements in portable battery-powered devices

Procurement Notes

Verify the specific suffix CAT116 to confirm the tape-and-reel packaging format and quantity. Ensure compatibility with RoHS3 directives if required by the target market regulations. Cross-reference the manufacturer datasheet for detailed handling and soldering profiles to maintain component integrity during assembly processes.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required. Compare the 10 kOhm input resistance against other variants like the DTC114 series if different drive currents are needed. Verify that the 50 V breakdown voltage aligns with the system's supply rails and transient requirements.

Part Context

This part belongs to the DTx series of pre-biased transistors from ROHM Semiconductor. It is functionally similar to the DTC114YCA but includes specific packaging and ordering suffixes. The DTA114YCAHZGT116 represents the PNP counterpart within the same family, offering complementary switching functionality for differential or push-pull configurations.

Replacement Considerations

Direct substitutes include the DTC114YCA and DTC114YCAT116TR. Verify pinout compatibility and electrical ratings before substitution. Alternative packages such as SOT-416 may require schematic adjustments due to pin configuration differences.
