DTC114TU3HZGT106

Overview

The DTC114TU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and a resistor ratio of 1. Key electrical parameters include a maximum collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain of 30 at 5 mA and 5 V, with a maximum operating frequency of 250 MHz. It supports a maximum operating temperature of +150 C and includes AEC-Q101 automotive qualification.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Features leak absorption characteristics to enhance stability in high-temperature environments.
• Complies with AEC-Q101 standards for automotive electronic component reliability.

Applications

• Automotive interface circuits requiring robust performance under varying thermal conditions.
• General-purpose inverter circuits in consumer electronics.
• Driver applications for low-power switching operations.

Procurement Notes

Verify the specific suffix HZGT106 against official ROHM documentation to confirm the exact tape-and-reel quantity and lead time specifications. Ensure compatibility with SOT-323 footprint requirements during PCB layout. Cross-reference the AEC-Q101 qualification status if the application mandates automotive-grade certification standards.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. The 50 V rating and 100 mA current capacity suit general switching tasks. Consider the 250 MHz frequency limit for signal integrity in high-speed applications. Verify that the 200 mW power dissipation aligns with the thermal management capabilities of the target system.

Part Context

This part belongs to the ROHM DTC114 series of pre-biased transistors. The TU3 designation indicates the SOT-323 package type. The HZGT106 suffix typically denotes specific packaging and reel configurations provided by the manufacturer. This series is designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity.

Replacement Considerations

Direct substitutes may include other ROHM parts within the DTC114 family with matching pinouts and electrical ratings, such as DTC114EU3 variants. Verify that any replacement maintains the same NPN polarity, 50 V breakdown voltage, and SOT-323 package dimensions to ensure mechanical and functional compatibility.
