MMSZ5253B-E3-18

Single Zener Diodes Overview

The MMSZ5253B-E3-18 is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 25 V with a standard tolerance of ±5%. The device operates within a test current range of 1.7 to 20 mA and features a maximum power dissipation of 500 mW at thermal equilibrium. It utilizes an SOD-123 surface-mount package, supports an operating temperature range from -55 °C to +150 °C, and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Utilizes silicon planar construction for reliable voltage regulation
• Provides standard ±5% Zener voltage tolerance for general-purpose applications
• Features ESD capability exceeding 8 kV via human body model and 800 V via machine model

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-E3' designation indicates RoHS compliance for commercial grade devices. Confirm that the '-18' suffix aligns with the required taped unit quantity per reel. Ensure the selected variant matches the necessary AEC-Q101 qualification status if automotive reliability is mandated.

Single Zener Diodes Selection Notes

Select this component when a 25 V Zener voltage with ±5% tolerance is required in a compact SOD-123 footprint. Consider the 500 mW power dissipation limit and the specified dynamic resistance characteristics. Verify compatibility with automated assembly processes due to the small surface mount package design.

Single Zener Diodes Part Context
