BZX84B33-G3-18

Single Zener Diodes Overview

The Vishay BZX84B33-G3-18 is a silicon planar Zener diode in the BZX84-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 33 V with a tight tolerance of ±2%. The device operates at a test current of 2 mA and dissipates up to 500 mW on lead or 300 mW on an FR-4 board. It features low reverse leakage current and dynamic resistance, ensuring stable voltage regulation across an operating temperature range of -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance for critical circuit stability

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix requirements for your assembly line. Confirm the tape and reel dimensions align with your pick-and-place equipment specifications. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders for production runs.

Single Zener Diodes Selection Notes

Select this component when a precise 33 V reference is required with minimal deviation. The ±2% tolerance makes it suitable for applications where standard commercial grades are insufficient. Consider the SOT-23 footprint constraints and the thermal resistance characteristics when designing the PCB layout for optimal heat dissipation.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX84-G series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter 2% tolerance grade, while the 'G3' suffix denotes the green, commercial-grade variant compliant with environmental regulations.

Single Zener Diodes Replacement Considerations

Substitute with other BZX84B33 variants from Vishay if packaging differs. Cross-reference with equivalent Zener diodes offering 33 V nominal voltage and ±2% tolerance in SOT-23 packages from other manufacturers, ensuring similar power dissipation and leakage characteristics.
