ATV30C251J-HF TVS - Diodes

The ATV30C251J-HF is a type of transient voltage suppressor diode (TVS - diode) manufactured and marketed by Littelfuse, Inc. This type of diode is commonly used in the protection and control of various electrical circuits and devices. The diode provides transient voltage and current protection, resulting in decreased operation noise and longer component life.The ATV30C251J-HF TVS – diode is a great choice for circuit protection, designed to handle high peak power and transient voltages up to 1500 Volts. It is rated with peak pulse power for 1,500 watts(@ 10/1000μs pulse widths)and clamping voltage of around 252 Volts, which makes it suitable for a broad range of applications ranging from consumer electronics to industrial equipment and components.The diode contains an integrated internal junction diode which is coupled with a special semiconductor, allowing the diode to act as a low impedance \'flow\' between the two components. This low impedance allows the diode to transfer current across the junction with minimal throttling of the current flow. The internal junction also works to suppress voltage transients, ensuring that the protected circuit stays within operational safety limits.The integration of an internal diode and the semiconductor allows the diode to protect sensitive circuits from voltage transients and other electrical hazards. Such transients can arise from lightning strikes, electromagnetic interference (EMI), and other over-voltage events. The diode\'s response time is fast enough to provide close-to-instant protection, and it can provide superior protection against current surges in milliseconds.The ATV30C251J-HF also incorporates a thermal shutdown feature which automatically shuts down the diode when the temperature of the part rises above 145°C. This temperature-activated shutdown provides additional protection for the protected circuit.In addition, the ATV30C251J-HF offers two additional levels of protection - a high and low clamp voltage. The high clamp voltage option allows the diode to clamp electrical pulses and short duration voltage transients at the peak value, while the low clamp voltage option provides additional protection from long-term, low frequency transients.The ATV30C251J-HF diode is a great choice for circuit protection and control, offering superior protection against various electrical hazards and transients. With its fast response time and reliable thermal shutdown feature, the diode provides reliable and cost-effective protection for sensitive electrical components and circuits in a wide range of applications.
