BZG03B110-M3-18

Single Zener Diodes Overview

The BZG03B110-M3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 110 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1.25 W and utilizes the DO-214AC (SMA) surface-mount package. Key electrical characteristics include a maximum Zener impedance of 200 Ohms, a reverse leakage current of 1 µA at 75 V, and a forward voltage of 1.2 V at 500 mA. The component supports a junction temperature up to 150°C and complies with RoHS 3 standards.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance
• Robust thermal performance with 150°C junction temperature rating
• Compact surface-mount design in DO-214AC package

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• Clamping applications in sensitive electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix -18 against the official datasheet to confirm tape-and-reel packaging requirements. Confirm RoHS 3 compliance status for your region. Check for obsolescence notices as Vishay frequently updates product lifecycles. Ensure the ±2% tolerance variant matches your circuit design needs compared to standard ±5% or ±6% options.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is required due to its ±2% tolerance. The 1.25 W power rating suits moderate current applications. Compare the 200 Ohm impedance against lower-impedance alternatives if stricter regulation under varying currents is needed. Verify the SMA footprint compatibility during PCB layout.

Single Zener Diodes Part Context

This part belongs to the BZG03B-M series, which distinguishes itself from the C-series by offering tighter voltage tolerances. The M3 suffix indicates lead-free construction compliant with EU directives. The BZG03C series typically offers wider tolerances like ±5% or ±6%, making the B-series suitable for higher accuracy requirements.
