DTC114EXV3T1

Overview

The DTC114EXV3T1G is an NPN silicon digital transistor manufactured by onsemi, designed to replace discrete devices and external bias resistor networks. It integrates a single transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor within a compact SC-89 package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 260 mW. The device features a typical input resistance of 10 kOhms and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single NPN transistor with a monolithic bias network comprising two resistors to eliminate external components.
• Reduces system cost and board space by consolidating the transistor and biasing circuitry into one surface-mount device.
• Designed for low-power applications requiring simplified circuit design through built-in biasing.

Applications

• Inverter circuits
• Interface logic
• Driver applications

Procurement Notes

Verify the complete part number includes the suffix 'G' for lead-free compliance when sourcing. Confirm the manufacturer is onsemi or its authorized subsidiaries. Check the specific datasheet revision date to ensure alignment with current manufacturing standards. Validate that the SC-89 package matches the intended PCB footprint requirements before procurement.

Selection Notes

Select this component for designs requiring an NPN digital transistor with integrated biasing in a small form factor. Ensure the required collector current does not exceed 100 mA and the voltage rating meets the 50 V limit. Consider the thermal management capabilities given the 260 mW power dissipation rating in the SC-89 package. Verify compatibility with the target operating temperature range of -55°C to +150°C.

Part Context

This component belongs to the DTC114EXV3T1 Series of NPN Silicon Digital Transistors. It is part of onsemi's portfolio of pre-biased transistors aimed at simplifying digital switching applications. The series is engineered to provide reliable performance in consumer electronics and industrial control systems where space efficiency is critical.

Replacement Considerations

Direct substitutes may include other NPN digital transistors with similar 100 mA current ratings and 50 V breakdown voltages in compatible packages. Verify pinout compatibility and internal resistor values (typically 10 kOhm) to ensure functional equivalence without redesigning the surrounding circuitry.
