MMBZ4708-E3-08

Single Zener Diodes Overview

The MMBZ4708-E3-08 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 22 V with a power dissipation rating of 350 mW. The component utilizes an SOT-23-3 surface-mount package and offers a voltage tolerance of ±5%. It operates within a temperature range of -55°C to +150°C and complies with RoHS3 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 22 V level
• Designed for compact surface-mount applications using the SOT-23-3 package
• Capable of operating in extended industrial temperature environments

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 22 V levels
• Over-voltage protection in portable electronic devices
• Clamping applications in low-power signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific power rating of 350 mW, as this differs from the standard 500 mW found in the larger MMSZ4708 variant. Confirm the SOT-23-3 package footprint matches the design layout. Ensure compliance with RoHS3 requirements is documented for the specific procurement batch.

Single Zener Diodes Selection Notes

Select this component when space constraints necessitate the SOT-23-3 form factor over the larger SOD-123. The 350 mW rating requires careful thermal management compared to higher-power alternatives. Verify that the 22 V breakdown voltage aligns precisely with the circuit's regulatory needs.

Single Zener Diodes Part Context

This part belongs to the MMBZ series of small-signal Zener diodes. It shares the same electrical characteristics as the MMSZ4708 but utilizes a smaller SOT-23-3 package instead of the SOD-123. This allows for higher component density on printed circuit boards while maintaining similar voltage regulation performance.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 22 V Zener diodes in the SOT-23-3 package with comparable power ratings. Cross-reference with Vishay's MMBZ4708 variants or equivalent parts from other manufacturers ensuring identical pinout and thermal specifications.
