DTC024XEBTL

Overview

The DTC024XEBTL is a single NPN digital transistor manufactured by Rohm Semiconductor, designed for surface-mount applications in the EMT3F (SOT-416FL) package. It integrates a base resistor (R1) of 22 kOhms to simplify circuit design by eliminating external biasing components. Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 50 V and a maximum continuous collector current (Ic) of 100 mA. The device features a minimum DC current gain (hFE) of 80 at Ic=5mA and Vce=10V, with a transition frequency (fT) of 250 MHz. Power dissipation is rated at 200 mW, and it operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a 22 kOhm base resistor to enable direct logic interface without external bias resistors.
• Provides high-speed switching capability with a transition frequency of 250 MHz.
• Supports standard logic levels with a 50 V collector-emitter voltage rating.

Applications

• Inverter circuits for microcontroller I/O expansion
• Driver stages for small-signal relays or LEDs
• Logic level shifting between different voltage domains

Procurement Notes

Verify the specific suffix EBTL against the official Rohm datasheet to confirm the exact resistance value and package variant. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm that the EMT3F footprint matches the target PCB layout requirements before finalizing orders.

Selection Notes

Select this component when a single NPN switch with integrated base biasing is required. The 22 kOhm internal resistor suits applications driven directly by standard logic outputs. Compare the 200 mW power dissipation rating against thermal constraints. Consider complementary PNP types from the same series if push-pull configurations are needed. Verify the 100 mA current limit meets load requirements.

Part Context

This component belongs to Rohm's DTC024 series of resistor-equipped bipolar transistors. The series offers various resistance combinations to optimize drive characteristics for different logic families. The EMT3F package provides a compact solution for space-constrained designs. This specific model focuses on general-purpose switching with moderate current handling capabilities.

Replacement Considerations

Direct substitutes include other NPN digital transistors with similar 22 kOhm base resistance and 50V ratings, such as the DTC124XEBTL or equivalent parts from other manufacturers offering the SOT-416FL package. Verify pinout compatibility and thermal performance before substitution.
