BZY55C4V7

Single Zener Diodes Overview

The BZY55C4V7 is a surface mount Zener diode manufactured by Taiwan Semiconductor Corporation, designed for low voltage stabilization and reference applications. It operates within a junction temperature range of -55°C to +150°C and features a nominal Zener voltage of 4.7 V with a ±5% tolerance at a test current of 5 mA. The device dissipates up to 500 mW of power and exhibits a maximum reverse leakage current of 0.5 µA. Packaged in an 0805 ceramic case, it meets JESD 201 class 1A whisker test requirements and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation within a wide selection range from 2.4 V to 36 V
• Utilizes a compact 0805 ceramic package suitable for high-density circuit designs
• Ensures reliability through compliance with moisture sensitivity level 1 per J-STD-020

Single Zener Diodes Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting application
• On-board DC/DC converter

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., RBG) to confirm packaging details, as standard packing is provided in 10,000-unit quantities on 13-inch tape and reel. Confirm RoHS compliance status and ensure the component meets JESD 201 class 1A whisker test requirements before final integration into the design.

Single Zener Diodes Selection Notes

Select this component when a small form factor is required for voltage regulation tasks. The 0805 ceramic package supports automated assembly processes. Ensure the operating environment stays within the specified thermal limits and that the required voltage tolerance aligns with the standard ±5% specification provided for this series.

Single Zener Diodes Part Context

This part belongs to the BZY55C series, which covers Zener voltages from 2.4 V to 36 V. The series is engineered for general regulation and voltage reference functions in consumer electronics. It offers a comprehensive range of package options tailored for customized protection in scaled, high-density circuit designs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZY55C series variants with matching voltage ratings, such as BZY55C4V3 or BZY55C4V7RBG. Verify that alternative components maintain identical 0805 footprint dimensions and 500 mW power dissipation capabilities to ensure mechanical and electrical compatibility.
