DTC024EUBTL

Overview

The DTC024EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes an internal base resistor (R1) and emitter-base resistor (R2), both typically rated at 22kΩ, enabling direct interface with logic gates without external components. Key electrical parameters include a minimum DC current gain (hFE) of 56 at 5mA and 10V, a maximum operating frequency of 250MHz, and a power dissipation capacity of 150mW. Packaged in the compact SOT-323FL (UMT3F) surface-mount format, it supports a maximum operating temperature of +150°C.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components, facilitating straightforward inverter circuit configuration.
• High-speed switching capability supported by a transition frequency of up to 250MHz for efficient signal processing.
• Compact SOT-323FL package design optimizes board space utilization while maintaining robust thermal performance.

Applications

• Logic level shifting and voltage translation between different digital domains
• Inverter circuits and buffer stages in embedded systems
• Switching applications in portable electronic devices

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and specific packaging configurations such as tape-and-reel quantities against current datasheet specifications. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent degradation prior to assembly.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for high-frequency switching applications. Compare hFE characteristics and saturation voltages against alternative models if specific gain thresholds are critical. Consider the 150mW power dissipation limit and thermal management requirements within the final enclosure design.
