Optimized for Space-Constrained Designs and High-Frequency Applications
TOKYO, Japan – Rohm Semiconductor, a global leader in semiconductor solutions, has unveiled its latest innovation in transistor technology: the DTA144EKAT146, a pre-biased PNP transistor designed to deliver exceptional performance in compact, surface-mount applications. Engineered for efficiency and reliability, this component is ideal for low-power switching, signal amplification, and high-frequency circuits in consumer electronics, industrial automation, and automotive systems.
Key Features and Benefits
1. Pre-Biased Design for Simplified Circuit Integration
The DTA144EKAT146 integrates dual 47kOhm resistors (R1 and R2) between the base and emitter, eliminating the need for external biasing components. This reduces PCB footprint and simplifies circuit design, accelerating time-to-market for developers.
2. High Voltage and Frequency Performance
With a collector-emitter breakdown voltage of 50V and a transition frequency of 250MHz, this transistor supports robust operation in high-voltage environments and high-speed switching applications, such as motor drivers and communication modules.
3. Ultra-Low Power Consumption
The device operates at a maximum collector current of 30mA and features a low collector cutoff current of 500nA, making it ideal for energy-sensitive applications like IoT sensors, wearables, and battery-powered devices.
4. Enhanced Thermal Efficiency
Packaged in a SMT3 (SOT-23-3) case, the DTA144EKAT146 combines a compact footprint (TO-236-3) with a maximum power dissipation of 200mW, ensuring reliable performance in space-constrained designs.
5. Optimized Saturation Characteristics
A low Vce saturation voltage of 300mV @ 10mA minimizes power loss during switching, improving overall system efficiency.
