BZG05B82-HM3-18

Single Zener Diodes Overview

The BZG05B82-HM3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 82 V and a maximum power dissipation of 3 W. The device is housed in the DO-214AC (SMA) surface-mount package. Key electrical specifications include a maximum reverse leakage current of 500 nA at 65 V, a Zener impedance of 200 Ohms, and a forward voltage of 1.2 V at 200 mA. It operates within a junction temperature range up to 150°C and holds AEC-Q101 qualification for automotive applications.

Single Zener Diodes Feature Summary

• Automotive-grade reliability with AEC-Q101 qualification
• High power dissipation capability of 3 W in compact SMA package
• Low reverse leakage current for stable voltage regulation

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronics
• Over-voltage protection in industrial control systems
• Clamping applications in high-power surface-mount designs

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix indicates the correct reel packaging configuration. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications (PCN) regarding manufacturing site changes or material updates before final procurement integration.

Single Zener Diodes Selection Notes

Select this component when a 3 W power rating is required in an SMA footprint. The 82 V breakdown voltage suits mid-range regulation tasks. Verify thermal management requirements for the 150°C junction limit. Compare against lower power alternatives if space constraints allow smaller packages like SOD-123 for reduced wattage needs.

Single Zener Diodes Part Context

This part belongs to the BZG05B series of high-power Zener diodes designed for robust performance. The HM3 suffix denotes Halogen-free and RoHS-compliant construction. The -18 suffix typically specifies tape-and-reel packaging for automated assembly processes, distinguishing it from cut-tape variants.
