BZY55B3V3

Single Zener Diodes Overview

The BZY55B3V3 is a surface-mount Zener diode from the BZY55B series by Taiwan Semiconductor, housed in an 0805 (Ceramics) package. It provides a nominal Zener voltage of 3.3 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 2 µA at 1.0 V and a Zener impedance of 85 Ω. It supports junction temperatures from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Offers high-precision voltage regulation with a standard ±2% tolerance on nominal Zener voltage.
• Utilizes a ceramic-based 0805 surface mount case for robust mechanical stability.
• Complies with JESD 201 class 1A whisker testing requirements.

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. Confirm RoHS compliance status and moisture sensitivity level ratings prior to integration into automated assembly processes. Ensure the selected variant matches the required voltage tolerance specifications for the target circuit design.

Single Zener Diodes Selection Notes

Select this component when precise low-voltage clamping is required in space-constrained designs. The ceramic construction offers distinct advantages over plastic packages regarding thermal performance and reliability. Verify that the operating current remains within the specified 5 mA test conditions to maintain the guaranteed ±2% voltage accuracy.

Single Zener Diodes Part Context

This part belongs to the BZY55B series, which covers a wide selection of Zener voltages ranging from 2.4 V to 36 V. All devices in this family share the same 0805 (Ceramics) form factor and 500 mW power dissipation rating. The series is designed for general-purpose surface mount applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZY55B3V0 and BZY55B3V6. Cross-brand replacements must match the 0805 footprint, 3.3 V nominal voltage, and ±2% tolerance constraints.
