BZV55C33/TR

Single Zener Diodes Overview

The BZV55C33/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 33 V with a tolerance of ±6%. The device operates in the DO-213AA (MiniMELF) package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 50 nA, a Zener impedance of 60 Ohms, and a test current of 5 mA. It supports an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using Zener breakdown characteristics
• Utilizes MiniMELF surface-mount packaging for compact circuit integration
• Engineered for high-temperature operation up to 175 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronics
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as the BZV55C33 series is produced by multiple vendors including MCC and Vishay. Confirm that the DO-213AA package matches your PCB footprint requirements. Ensure the ±6% tolerance aligns with your design specifications, as other variants may offer tighter tolerances or different voltage ratings.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with a 33 V rating is required. The DO-213AA package offers a smaller form factor compared to axial leads. Consider the 500 mW power dissipation limit and the 60 Ohm impedance at the specified test current when designing the biasing network.

Single Zener Diodes Part Context

This part belongs to the BZV55C series of Zener diodes, which are widely used for general-purpose voltage regulation. The 'TR' suffix typically indicates tape-and-reel packaging suitable for automated assembly processes. The series covers various voltage ratings within the same physical package outline.

Single Zener Diodes Replacement Considerations

Direct substitutes include BZX55C33-TR (Vishay), though it uses a through-hole DO-35 package. For surface-mount compatibility, verify equivalent parts in the DO-213AA package from other manufacturers, ensuring matching voltage, power, and impedance specifications.
