BZD27B6V8P-HM3-18

Single Zener Diodes Overview

The BZD27B6V8P-HM3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 6.8 V with a maximum power dissipation of 800 mW. The device is designed for surface mount applications in the DO-219AB (SMF) package. It operates within a temperature range of -65°C to 175°C and exhibits a reverse leakage current of 1 µA at 27 V. The forward voltage is specified as 1.2 V at 200 mA, with a maximum impedance of 40 Ohms.

Single Zener Diodes Feature Summary

• Surface mount construction in a compact DO-219AB (SMF) package
• High operating junction temperature capability up to 175°C
• Low leakage current characteristics for stable regulation
• Lead-free finish compliant with RoHS standards

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 6.8 V levels
• Over-voltage protection stages in consumer electronics
• Clamping applications in signal processing paths
• Power supply regulation modules

Single Zener Diodes Procurement Notes

Verify the complete part number including the suffix -18 to confirm reel packaging specifications. Ensure compatibility with standard SMF footprint dimensions during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V Zener voltage is required in a small surface mount form factor. Consider the 800 mW power rating for thermal management requirements. The DO-219AB package offers a compact solution for space-constrained designs compared to larger axial packages.

Single Zener Diodes Part Context

This component belongs to the BZD27B series of silicon planar Zener diodes from Vishay. The series is characterized by low noise and high stability. The HM3 suffix indicates a lead-free terminal finish. The -18 suffix typically denotes tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay BZD27B series variants with identical voltage and package specifications. Cross-brand replacements must match the 6.8 V Zener voltage, 800 mW power rating, and DO-219AB footprint to ensure mechanical and electrical compatibility.
