The Weidmüller part number 7940099843 is a Zener diode, specifically identified as the SP-DK4 TS32 model with a 25 Ohm resistance and a 33V Zener voltage rating. This component is designed for transient suppression applications within electrical circuits. It adheres to RoHS compliance standards, ensuring it meets environmental regulations regarding hazardous substances. The device serves as a protective element against voltage spikes, safeguarding sensitive electronic components from damage caused by overvoltage events in industrial or commercial settings.
Verify the exact specifications against the official manufacturer datasheet before procurement. Confirm that the 33V Zener voltage and 25 Ohm parameters match your design requirements. Ensure the SP-DK4 TS32 designation aligns with your bill of materials. Check for any specific handling instructions related to ESD sensitivity during storage and installation.
Select this component when a 33V Zener diode with 25 Ohm characteristics is required for transient suppression. Consider its RoHS compliance if environmental regulations are a priority. Evaluate its physical dimensions and mounting requirements against your PCB layout constraints. Compare its clamping voltage and power dissipation capabilities with alternative solutions to ensure adequate protection for the target circuit.
Weidmüller is a German multinational company specializing in electrical interconnection, automation, and industrial IoT technologies. Founded in 1850, the company provides comprehensive solutions for industrial environments. The SP-DK4 series represents their range of protection components designed for robust performance in demanding applications. This part falls under their broader portfolio of electronic protection devices.
Publicly confirmed substitute part numbers for Weidmüller 7940099843 are not available in the provided documentation. Cross-referencing should be performed using technical parameters such as 33V Zener voltage and 25 Ohm resistance to identify compatible alternatives from other manufacturers.
