Overview
The Littelfuse S4006V is a transient voltage suppressor (TVS) diode designed for overvoltage protection in electronic circuits. It is housed in a TO-251-3 surface-mount package, also known as DPAK. The device features a standoff voltage of 5.0 V and a minimum breakdown voltage of 5.56 V at the test current. It provides a peak pulse power rating of 400 W under standard 10x1000 µs waveforms. The component exhibits a maximum clamping voltage of 8.9 V when subjected to an 8.3 A peak pulse current. It is available in unidirectional polarity configurations.
Feature Summary
- Provides robust protection against transient voltage surges and electrostatic discharge events
- Features low-profile surface-mount packaging suitable for automated assembly processes
- Offers fast response times to clamp high-energy transients effectively
Applications
- Protection of data ports and communication interfaces
- Overvoltage suppression in power supply input lines
- Surge protection for sensitive semiconductor components
Procurement Notes
Verify the specific suffix codes on the component marking to confirm exact electrical tolerances and polarity variants. Ensure the ordering part number matches the required package style and lead configuration. Cross-reference the manufacturer's latest datasheet to confirm compliance with current environmental standards such as RoHS before finalizing procurement orders.
Selection Notes
Select this component based on the circuit's operating voltage requirements relative to the 5.0 V standoff rating. Evaluate the expected surge energy levels to ensure they remain within the 400 W peak pulse power capability. Consider the thermal dissipation characteristics of the TO-251-3 package for the intended application environment.
Part Context
This component belongs to Littelfuse's general-purpose TVS diode portfolio, which focuses on protecting electronics from voltage spikes. The S4006V utilizes a silicon junction technology optimized for rapid clamping action. It serves as a critical safety element in various consumer and industrial electronic assemblies requiring reliable transient suppression.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalent parts. Ensure any alternative device maintains compatible voltage ratings and package dimensions.
