MMBZ5231C-G3-18

Single Zener Diodes Overview

The MMBZ5231C-G3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 5.1 V with a tolerance of ±2%. The device has a maximum power dissipation of 225 mW and is housed in an SOT-23-3 surface-mount package. It operates within a temperature range of -55°C to +150°C and complies with RoHS 3 standards.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance for sensitive circuit applications.
• Utilizes a compact SOT-23-3 surface-mount package suitable for space-constrained designs.
• Operates reliably across a wide industrial temperature range from -55°C to +150°C.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 5.1 V levels
• Over-voltage protection in portable electronic devices
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS 3 compliance status and check for recent Product Change Notifications (PCNs) that may affect material composition or manufacturing location. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain reliability before soldering.

Single Zener Diodes Selection Notes

Select this component when a low-power, high-precision Zener diode is required in a small footprint. The ±2% tolerance offers better accuracy than standard ±5% variants. Consider the 225 mW power rating limits for thermal management in dense PCB layouts compared to higher-power SOD-123 alternatives.

Single Zener Diodes Part Context

This part belongs to the MMBZ5231 series of Zener diodes. It shares the same electrical characteristics as the MMSZ5231B but utilizes a different SOT-23-3 package instead of SOD-123. The 'G3' suffix indicates lead-free and RoHS 3 compliance, while '-18' denotes reel packaging.

Single Zener Diodes Replacement Considerations

MMSZ5231B-E3-18 is a parameter-equivalent alternative in the SOD-123 package. BZT52C51 variants offer similar functionality in SOD-123 packages. Verify pinout compatibility and thermal performance differences when substituting between SOT-23-3 and SOD-123 footprints.
