BZT52C11-G3-18

Single Zener Diodes Overview

The BZT52C11-G3-18 is a silicon planar Zener diode from Vishay Semiconductors, designed for surface-mount applications in the SOD-123 package. It provides a nominal Zener voltage of 11 V with a standard tolerance of ±5%. The device operates within a temperature range of -55 °C to +150 °C and features a maximum power dissipation of 500 mW at ambient conditions. Electrical characteristics include a test current of 5 mA, a reverse leakage current of 100 nA at 8.5 V, and a dynamic resistance of 20 Ω.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Complies with international E24 standard grading for voltage selection
• Features a compact SOD-123 surface-mount footprint
• Includes cathode marking for polarity identification

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify the specific suffix '-G3-18' to confirm the commercial grade designation and the 10,000-unit reel packaging format. Ensure that the required Zener voltage tolerance aligns with the 'C' series specification of ±5% rather than the tighter 'B' series requirements. Confirm compliance with RoHS directives and material categorization standards before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a single-diode configuration is sufficient for circuit design. The SOD-123 package offers a balance between thermal performance and board space efficiency. Consider the positive temperature coefficient above 5 V when designing for environments with significant thermal variations. Verify that the maximum allowable Zener current fits within the system's power budget constraints.

Single Zener Diodes Part Context

This part belongs to the BZT52-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a wide range of voltages from 2.2 V to 75 V using standardized E24 values. The 'G3' suffix indicates a lead-free, halogen-banned commercial grade product, while the '-18' suffix specifies the 13-inch tape and reel packaging format for automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZT52C11-E3-18 and BZT52C11-HE3-18, which share identical electrical specifications but differ in environmental compliance or manufacturing origin. Cross-manufacturer replacements must match the 11 V nominal voltage, ±5% tolerance, and SOD-123 package dimensions.
