The V180ZA05 is a Transient Voltage Suppressor (TVS) component designed to protect circuits from high voltage transients. The component\'s Shockless Diode architecture is designed for applications in the industrial, automotive, and medical industry. The V180ZA05 aerospace grade part is designed to protect the most sensitive analog and digital circuits in extremely harsh environments. The V180ZA05 is capable of providing bidirectional protection through its symmetric breakdown voltage withstanding capability. When the applied voltage exceeds the breakdown voltage of the V180ZA05, it acts as a metal oxide varistor (MOV) to automatically limit the current flow and clamp the circuit voltage to the breakdown voltage level. If the applied voltage exceeds the breakdown voltage of the V180ZA05, the device will act as a diode and limit the current flow to a safe level. The V180ZA05 is designed to handle a wide variety of transient protection applications. It can provide protection from ESD, inductive ring wave pulses, fused lightning discharges, or short dv/dt induced transients. This Shockless Diode TVS device is ideal for telecom, automotive, or industrial power supplies, generator and motor controls, or any application where catastrophic overshoot or EMI/RFI needs to be eliminated.The V180ZA05 offers fast response time and low clamping voltage for superior transient protection. It is rated to handle high peak pulse power up to 400W (10/1000µs) and can withstand surge currents of up to 1500A. This advanced protection device features an excellent thermal resistance of < 0.03ºC/W as well as up to 2000V working voltage.The V180ZA05 operates on a simple principle-that of a two-terminal diode. It acts as a protector by providing an internal path for the current to flow through, before the voltage is allowed to set beyond the pre-defined safe level. This allows the device to protect the equipment from surges and spikes, and it also dissipates the energy absorbed. Since the clamping voltage of the TVS remains constant, it effectively clamps the voltage and limits the current for a predefined time. The device is also designed with advanced gating technology to distinguish damaging from harmless transients. The Bidirectional TVS component also has the well-designed architectures of a High Temperature Reverse Standoff, ESD Clamping Capability, EFT clamping Capability, and Low Reverse Leakage Current to provide reliable design and protection in harsh environments. Thus, providing extra safety measures to the application circuit. For increased protection, the V180ZA05 has a built-in Positive Temperature Coefficient (PTC) protection device for temperature sensing and protection. This ensures that the TVS component will not be subjected to continuous surge and overload conditions. The device will detect any temperature increase and indicate the current overload through its PTC circuit. As a result, no permanent damage occurs due to high voltage surges or overloads. The V180ZA05 TVS feature low capacitance and highly reliable ESD protection. This is crucial for protecting sensitive equipment against ESD events. The device’s small size and low profile ensure it can fit easily on a small amount of boardspace. Additionally, the device is RoHS Compliant, Halogen-Free, and Lead-Free, making it an ideal choice for applications that require higher environmental protection standards. The V180ZA05 is designed specifically for voltage transient and EMI/RFI suppression using a Shockless Diode architecture. Its symmetric breakdown voltage allows for bidirectional protection, while its PTC protection provides added safety in high current and temperature conditions. The device’s built-in ESD and EFT clamping capabilities make it ideal for telecom, automotive, industrial, and medical surge protection applications. With its robust design and superior transient protection capabilities, the V180ZA05 is an excellent choice for protecting against voltage transients, EMI/RFI, and overload conditions.
