DDTC124XE-7

Overview

The DDTC124XE-7 is an NPN pre-biased small signal transistor manufactured by Diodes Incorporated, housed in a SOT523 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 22kΩ and R2 = 47kΩ. The device supports a maximum supply voltage (VCC) of 50V and a continuous collector current (IC) of 100mA. Electrical characteristics include a minimum DC current gain (hFE) of 68 at 5mA output current, a transition frequency (fT) of 250MHz, and a power dissipation rating of 150mW. Operating temperatures range from -55°C to +150°C.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated unequal biasing resistors (R1≠R2) simplifying circuit design
Totally lead-free and fully RoHS compliant manufacturing
Halogen and antimony free "Green" device composition

Applications

General-purpose switching applications
Driver circuits for logic interfaces
Automotive electronics requiring specific change control protocols

Procurement Notes

Verify the complete part number includes the suffix '-7-F' for reel packaging containing 3,000 units per carrier. Confirm that the ordering information matches the required resistor ratio tolerance and marking code 'N18'. Ensure compliance with J-STD-020 moisture sensitivity level 1 requirements during storage and handling procedures.

Selection Notes

Select this component when an NPN configuration with distinct base and emitter resistors is required. The 22kΩ input resistor suits moderate drive currents, while the 47kΩ output resistor aids in leakage management. Verify that the 100mA output current capability meets the load requirements and that the SOT523 footprint fits the PCB layout constraints.

Part Context

This component belongs to the DDTC(R1≠R2 Series)E family of pre-biased transistors. It serves as the NPN counterpart to the complementary PNP types available in the DDTA series. The device utilizes standard SOT523 mechanical dimensions and is designed for high-volume surface mount assembly processes.

Replacement Considerations

Direct substitutes within the same manufacturer's portfolio include other members of the DDTC(R1≠R2 Series)E such as DDTC123YE or DDTC143ZE, provided their specific resistor ratios match the circuit design requirements. Cross-manufacturer replacements must be verified against absolute maximum ratings and pinout configurations.
