The SSM3K15ACT (TPL3) is an advanced, power-efficient and new process Hitachi-made static MOSFET (SMOSFET), which is considered one of the most important power transistors. This powerful transistor can be used in many different applications that require powerful and efficient power control, especially when dealing with large amounts of power. It is designed to be robust and reliable in many power control scenarios, and has a long operating life as well.

Applications

The SSM3K15ACT (TPL3) can be used for various applications such as motor control, power distribution, and power conditioning. It is also suitable for use in high-power DC-DC converters, AC induction motors, and switching power supply. It is also ideal for driving LEDs, lighting power supply, and any other current-sensing applications that require low-power control. Additionally, it can be used for power conditioning in automotive systems, industrial automation and robotics.

Features

The SSM3K15ACT offers many advantages, such as its excellent power conversion efficiency, low on-resistance, low standard gate charge, low transition time, fast switching, scaleable current handling capability, low profile Dual- and third-channel characteristics, and low thermal resistance. In addition, it also has superior immunity against ESD and surge, as well as excellent static characteristics and ruggedness.

It features a level-shifting input stage and high-current output stage, which allows the SSM3K15ACT (TPL3) to be used in various power supply systems. Additionally, it has an exceptional low-power turn-on response and current limiting protection, which makes it suitable for use in power switching applications. Finally, this power transistor also provides a high-input common-mode noise rejection and excellent radiation immunity.

Working Principle

The SSM3K15 ACT (TPL3) is a static MOSFET, which has three main terminals – source, drain, and gate. When the gate is at a higher voltage than the source, it allows current to pass to the drain. When the gate is at a lower voltage than the source, it prevents current from passing to the drain. This is the essential principle behind its operation. In more technical terms, it is a three-terminal device that consists of an insulated-gate field-effect transistor and a junction field-effect transistor.

The main feature of a static MOSFET is its low on-resistance, which helps minimize power losses in the circuit. The two gates of the SSM3K15ACT (TPL3) allow control of both the on-resistance and the reverse-bias leakage current. Besides its low resistance, this device also offers excellent static performance and robustness, making it suitable for use in high-power switching circuits.

Advantages

The SSM3K15ACT (TPL3) offers some great advantages, compared to conventional transistors such as bipolar transistors. It offers high current density, low on-resistance and low power-turn-on response time. In addition, it consumes less power, operates more reliably and has a longer service life. The static MOSFET also provides a higher voltage blocking capability and better noise immunity, compared to conventional power transistors.

The SSM3K15ACT (TPL3) is a very reliable power transistor that is suitable for many applications, from controlling high-power switching circuits to providing low-power control for current sensing applications. Its low resistance, robustness, fast switching, and excellent static performance makes it a preferred choice for many power-control solutions today.
