TVS Diode Arrays (SPA® Diodes) Expertise Applied | Answers Delivered 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 Forward Voltage Drop (SP72x Series only) The maximum forward voltage drop between an input pin and respective power supply pin for a specific forward current. Reverse Voltage Drop or Breakdown...

TVS Diode Arrays (SPA® Diodes) Transient Voltage Threats and Scenarios Transient Threats – What Are Transients? 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...

TVS Diode Arrays (SPA® Diodes) 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: • Walking across a carpet: 35kV @ RH = 20%;1.5kV @ RH = 65% The switching of inductive loads...

TVS Diode Arrays (SPA® Diodes) ESD Suppression Strategies and Standards Why Implement Circuit Protection? 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, in contrast to switching and surge transients, has a very short transition from zero to maximum current and voltage. The rise time of an ESD event is less than 1 nanosecond (1ns), while the other transients take longer than 1 microsecond (1µs) to reach their peaks. ESD can be generated from a wide range of everyday factors such as very dry air,...
