DTB113ZCT116

Overview

The DTB113ZCT116 is a single PNP digital transistor from the ROHM Semiconductor DTx series, housed in an SOT-23-3 (SST3) surface-mount package. It integrates bias resistors to simplify circuit design by eliminating external components for inversion logic. Key electrical specifications include a collector-emitter voltage of -50 V and a continuous collector current of -500 mA. The device features a typical input resistance of 1 kOhm with a resistor ratio of 10. It supports a maximum operating frequency of 200 MHz and has a power dissipation rating of 200 mW. The minimum DC current gain is specified as 56 at -50 mA and -5 V.

Feature Summary

• Integrates built-in bias resistors to enable direct connection to logic circuits without external base resistors.
• Provides high-speed switching capability suitable for frequencies up to 200 MHz.
• Utilizes a compact SOT-23-3 package for efficient space-saving surface mount applications.

Applications

• Inverter circuits requiring simplified input stages.
• Driver circuits for small-signal switching applications.
• Logic level translation interfaces in portable electronic devices.

Procurement Notes

Verify the specific suffix CT116 corresponds to the required tape and reel packaging configuration before ordering. Confirm that the component meets RoHS compliance requirements for the target assembly process. Ensure the procurement channel provides authentic ROHM Semiconductor products to avoid counterfeit risks associated with standard discrete semiconductors.

Selection Notes

Select this component when a PNP digital transistor with a 1 kOhm input resistance is required. Compare against the DTC113Z series if an NPN polarity is needed instead. Consider the DTB143Z series if a higher input resistance value such as 4.7 kOhm is necessary for the specific drive current constraints of the application.

Part Context

This part belongs to the ROHM DTx series of pre-biased transistors. These devices combine bipolar junction transistors with internal resistor networks. The DTB113Z variant specifically denotes the PNP polarity and the 1 kOhm input resistance characteristic within the broader family of digital transistors offered by the manufacturer.

Replacement Considerations

The DTB113ZC is listed as a part number alias for this component. Verify pinout compatibility and electrical tolerances when substituting with other PNP digital transistors from different manufacturers or alternative ROHM series parts.
