MMSZ5266BT3

Single Zener Diodes Overview

The MMSZ5266BT3G is a single Zener voltage regulator diode manufactured by onsemi, housed in an SOD-123 surface-mount package. It features a nominal Zener voltage of 68 V with a ±5% tolerance and a maximum steady-state power dissipation rating of 500 mW. The device operates within a junction temperature range of -55°C to +150°C and exhibits a maximum reverse leakage current of 100 nA at 52 V. Its maximum Zener impedance is specified as 230 Ohms.

Single Zener Diodes Feature Summary

• Designed for optimal automated board assembly using the compact SOD-123 plastic case.
• Provides general-purpose voltage regulation suitable for medium-current applications.
• Features high electrostatic discharge protection rated at Class 3 per the Human Body Model.

Single Zener Diodes Applications

• Voltage regulation circuits
• Protection against overvoltage transients
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'T3G' indicates a 10,000-unit tape and reel packaging format. Confirm RoHS compliance status and lead-free finish requirements. Ensure the ordering part number matches the exact voltage and tolerance specifications required for the design.

Single Zener Diodes Selection Notes

Select this component when a 68 V reference or clamp is needed in a space-constrained surface-mount layout. Evaluate the thermal resistance characteristics if operating near the maximum power dissipation limit. Consider the impedance value for dynamic load regulation requirements.

Single Zener Diodes Part Context

This device belongs to the MMSZ52xxxT1G series of Zener voltage regulators. The series offers a wide reverse voltage range from 2.4 V to 110 V in the same SOD-123 package style. It serves as a direct alternative to older leadless package styles while maintaining standard electrical performance metrics.
