1N5942

Single Zener Diodes Overview

The Microchip Technology 1N5942 is a silicon unidirectional Zener voltage regulator diode housed in a DO-41 glass axial-leaded package. It provides a nominal Zener voltage of 51V with a maximum power dissipation of 1.5W. The device features a tight voltage tolerance of ±2% and operates within an extended temperature range from -65°C to +150°C. Key electrical characteristics include a maximum Zener impedance of 70 Ohms, a reverse leakage current of 1µA at 38.8V, and a forward voltage drop of 1.2V at 200mA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation using a 51V Zener breakdown characteristic.
• Utilizes a hermetically sealed glass encapsulation for high thermal stability.
• Supports through-hole mounting via an axial lead configuration.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for transient suppression.

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., CP, BPE3) against official datasheets to confirm exact tolerance and screening levels. Ensure the selected variant matches the required JEDEC registration or military screening standards. Confirm RoHS compliance status if environmental regulations apply to the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 51V regulation point is required with high precision. The 1.5W power rating supports moderate current loads. Verify that the operating environment stays within the specified temperature limits. Consider the DO-41 package dimensions for PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5913B through 1N5956B series of 1.5-watt Zener diodes manufactured by Microchip Technology. The series offers a wide voltage range from 3.3V to 200V. Variants are available with different tolerances and screening options to meet diverse reliability requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5942CP and 1N5942BPE3. Verify pinout compatibility and ensure the replacement meets the 51V nominal voltage and 1.5W power dissipation specifications.
