The TVS Zener diodes are one of the most core devices for protecting the circuit from transient voltage damage. The PESD2IVN-UX is an advanced protection diode that offers a combination of excellent electrical characteristics and features for advanced high voltage protection in consumer and computer electronics applications. It is designed specifically for low leakage and small size, making it an ideal choice for high-performance and cost-sensitive applications.The PESD2IVN-UX diode is a breakdown voltage regulator diode that provides protection against damaging excessive voltage transients without causing permanent damage to the circuit. It is constructed from two silicon-based PN junction and an alternating layer of cadmium sulfide and cadmium selenide. The PESD2IVN-UX offers a wide breakdown range, from 10V to 5VS, with low capacitance and low leakage current. The device also has a high speed response time to protect against fast-changing transients. The primary application of the PESD2IVN-UX is in consumer and computer electronics to provide surge protection. The high voltage protection provided by its PN junction prevents short circuits from high voltage transients and ESD shocks. It is also effective for protecting sensitive microelectronic circuits from static discharges and over-voltage conditions. Additionally, the diode is used in high-speed signal line protection to ensure that noise and/or signal transients do not have a negative impact on the signal quality.In terms of its working principle, the PESD2IVN-UX diode works in two ways. The first is a reverse-blocking mode, which prevents current flow in the reverse direction. When the diode is subjected to a reverse-biased voltage, the diode remains in the blocking mode until the voltage reaches the Zener voltage. In other words, the diode remains in the block mode until it reaches its maximum breakdown voltage when the applied reverse voltage exceeds the specified value. The second protection principle offered by the diode is the forward-clamping mode, which further limits the maximum potential current flow through the diode. This occurs when the diode is subjected to an excessive forward voltage and the voltage level approaches a predetermined maximum value. When this occurs, the PN junction of the diode breaks down, thus creating a low impedance path that limits the potential current flow. In other words, the PESD2IVN-UX acts as a forward voltage regulator, allowing the subjected circuit to remain safe despite the excessive voltage.In conclusion, the PESD2IVN-UX diode is an advanced protection diode with outstanding characteristics and features for protecting consumer and computer electronics from voltage transients and other risks. With its wide breakdown range, low capacitance, low leakage current, and high speed response time, it is an ideal choice for high-performance, cost-sensitive applications. The diode functions according to two principle modes, reverse-blocking and forward-clamping, to protect the subjected circuit from excessive voltage and current.
