13 pieces of 1.5KE47CA transient voltage suppressor diodes in DO2012 package. Overview The 1.5KE47CA is a transient voltage suppressor (TVS) diode designed to protect electronic circuits from voltage transients and surges. This lot includes 13 pieces in the DO2012 package, suitable for reliable surge protection in a variety of applications. These devices use silicon avalanche technology to clamp overvoltage events and help prevent damage to sensitive components. Key benefits Provides surge and transient protection for power inputs, rails, and interfaces, helping to extend the life of downstream circuitry. Fast response to voltage spikes, helping to limit peak voltages experienced by protected circuits. Compact DO2012 package enables straightforward substitution and insertion into existing boards or assemblies. Durable, siliconbased TVS diodes designed for reliable operation under surge conditions. Readytouse quantity (13 pieces) for small to mediumvolume projects or stocking purposes. Key attributes Function: transient voltage suppressor diode for overvoltage protection. Model: 1.5KE47CA. Series: 1.5KE family. Package: DO2012. Material: silicon (avalanche diode technology). Rating class: part of the 1.5KE47 family (47V class range) intended for transient suppression on circuits around that voltage level. Quantity: 13 pieces in this listing. Compatibility and use Typical applications include protection of power supplies, DC rails, and sensitive electronics from transient events on input lines or interfaces. Suitable as a dropin protection component for boards and assemblies that use the DO2012 package format. For results, select the correct variant (unidirectional vs bidirectional is specified in datasheets) and review the applicable peak pulse and clamping specifications in the official data sheet before design implementation. Use cases Power supply input protection: place the TVS across the input rails to clamp surges coming from the connector or power line, protecting downstream regulation and ICs. DC bus protection in consumer electronics: protect the main DC bus from transient spikes caused by switching, load changes, or external disturbances. Interface and data line protection: safeguard signal lines and communication interfaces that may be exposed to transient events or ESD, by placing the TVS between the line and path. Care and installation notes Verify correct device orientation and polarity according to the specific circuit and datasheet guidelines. Ensure the operating environment and mounting conditions match the device's intended use, including any heat dissipation considerations if applicable. Consult the datasheet for the exact electrical characteristics, and confirm whether this variant is suitable for your unidirectional or bidirectional protection needs.
