TVS Diode Arrays (SPA® Diodes) Littelfuse* Expertise Applied | Answers Delivered Definitions and Terms Liability Definitions Operating Voltage Range (VSUPPLY; SP72x Series only) The range limits of the power supply voltage that may be across the V+ and V- terminals. The SCR/Diode arrays do not have a fixed breakover or operating voltage. These devices 'float' between the input and power supply rails and thus the same device can operate at any potential within its range. Forward Voltage Drop (SP72x Series only) The maximum forward voltage drop between an input pin and respective power supply...

TVS Diode Arrays (SPA® Diodes) Expertise Applied | Answers Delivered Voltage Transients are defined as short duration surges of electrical energy and are the result of the sudden release of energy previously stored or induced by other means, such as heavy inductive loads or lightning. In electrical or electronic circuits, this energy can be released in a predictable manner via controlled switching actions, or randomly induced into a circuit from external sources. Repeatable transients are frequently caused by the operation of motors, generators, or the switching of reactive circuit...

Expertise Applied | Answers Delivered Transient Voltage Threats and Scenarios (continued)Electrostatic Discharge (ESD)Inductive Load Switching Electrostatic discharge is characterized by very fast rise times and very high peak voltages and currents. This energy is the result of an imbalance of positive and negative charges between objects. ESD that is generated by everyday activities can far surpass the vulnerability threshold of standard semiconductor technologies. Following are a few examples: The switching of inductive loads generates high energy transients which increase in magnitude...

TVS Diode Arrays (SPA® Diodes) Expertise Applied | Answers Delivered It is important to consider that most electronic equipment will spend 99% of its useful life in environments where it is subject to ESD. ESD can be generated from a wide range of everyday factors such as very dry air, static from plastics, or walking across a floor or carpet, and can be present during every phase of useful life from manufacturing, to product shipping, receiving, to field handling. Electrostatic Discharge (ESD) causes millions of dollars worth of damage to electrical components, rendering circuit boards...
