TVS diodes, or transient voltage suppressors (TVSs), form the backbone of many electrical systems. Discrete TVSs are commonly used in automotive, avionics, and transportation industries to protect sensitive components from transient voltages. The TISP4070J1BJR is a 40V P-channel MOSFET that is housed in an SOT-23 package for high-speed switching and protection applications. This device has a low on-resistance, excellent on-state performance, and superior durability even in harsh operating conditions.

The TISP4070J1BJR is designed to control and reduce overvoltage events that may occur on systems that rely on powered circuits. It is therefore used in a wide range of applications, such as automotive ECUs and other electronic modules, computers, LCD screens, and LED lights. The TISP4070J1BJR can also be used as a low-noise shunt switch and current limiter. Thanks to the low on-resistance of the device and its multi-level protection circuit, the TISP4070J1BJR is uniquely suited to applications that require fast-switching and transient protection.

The TISP4070J1BJR works by clamping the voltage at a certain level and thereby preventing further damage to the affected components. The device has a threshold voltage of 5.4V, which is the voltage level at which the threshold voltage clamping begins. This ensures that the voltage does not exceed the threshold voltage and is thereby instantaneous current is limited as well. Once the overvoltage situation has been resolved, the protection circuitry prevents further current surges from damaging the circuit.

The TISP4070J1BJR can also be used to control inrush currents. As the device switches on, its clamping voltage ensures that high inrush currents are prevented, thus providing a safe and reliable start-up operation. In addition, the device has a reverse leakage current of 0.1uA, ensuring that even when there is an inductive load, the TISP4070J1BJR is able to effectively control and limit the inrush current. The device also has very low selective leakage current, meaning that it is able to provide high-quality protection against ESD.

Overall, the TISP4070J1BJR is an effective, reliable, and durable electronic device used to protect sensitive circuits from overvoltage. It enables fast-switching and transient protection, as well as inrush current control, making it ideal for use in harsh or extreme environments. The device’s multi-level protection circuit ensures superior protection against ESD and current surges, making it a great choice for applications that require high-quality protection against electrical damage.
