1N5940B3P-TP

Single Zener Diodes Overview

The 1N5940B3P-TP is a 3.0 Watt Zener diode manufactured by Micro Commercial Components (MCC) in the DO-41 axial through-hole package. It provides a nominal Zener voltage of 43 V with a ±5% tolerance. The device features a glass passivated junction and operates within a temperature range of -55°C to +175°C. Key electrical parameters include a maximum dynamic impedance of 53 Ohms at a test current of 8.7 mA, a knee current of 0.25 mA, and a maximum reverse leakage current of 1 µA at 32.7 V.

Single Zener Diodes Feature Summary

• Glass passivated junction for enhanced stability
• High operating junction temperature capability up to 175°C
• Lead-free finish compliant with RoHS standards

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm the specific suffix requirements for halogen-free availability if needed. Ensure the ordering information matches the required packing format, such as bulk or tape and reel options, prior to finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 43 V reference with high power dissipation capacity is required. The DO-41 package suits applications needing robust through-hole mounting. Consider the 53 Ohm dynamic impedance for circuit stability requirements. Verify thermal derating curves are adequate for the intended ambient operating conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5918B3P through 1N5956B3P series, covering Zener voltages from 5.1 V to 200 V. All devices in this series share the same 3.0 Watt power rating and DO-41 package dimensions. The series offers a wide range of voltage options while maintaining consistent physical and thermal characteristics across the product line.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 43 V Zener voltage, 3.0 W power rating, and DO-41 package. Verify that alternative components meet the same 53 Ohm dynamic impedance and 175°C junction temperature limits to ensure functional equivalence.
