MMSZ5244BT1G

Single Zener Diodes Overview

The MMSZ5244BT1G is a single Zener diode from the MMSZ52xxxT1G series, manufactured by onsemi. It features a nominal reverse Zener voltage of 14 V with a ±5% tolerance range (13.30 V to 14.70 V). The device operates at a test current of 9.0 mA and exhibits a maximum dynamic impedance of 15 Ω. It has a maximum power dissipation rating of 500 mW and a low reverse leakage current of 100 nA at 10 V. Packaged in a surface-mount SOD-123 case (CASE 425), it supports a junction temperature range from -55°C to +150°C.

Single Zener Diodes Feature Summary

• Surface-mount plastic SOD-123 package designed for optimal automated board assembly
• General-purpose medium current capability with high-density application suitability
• ESD protection rated Class 3 (> 16 kV) per Human Body Model
• Lead-free construction compliant with RoHS standards

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against electrostatic discharge in sensitive electronics
• Clamping applications in general-purpose electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'BT1G' corresponds to the 3,000-unit tape and reel shipping configuration. Confirm that the component marking matches the specified code 'H4' for this voltage variant. Ensure the procurement documentation explicitly states compliance with lead-free manufacturing processes as defined by the manufacturer's specifications.

Single Zener Diodes Selection Notes

Select this component when a 14 V reference is required within a compact surface-mount footprint. The 500 mW power rating allows for moderate current handling compared to smaller packages. Consider the 15 Ω dynamic impedance for applications needing tighter voltage stability under varying load conditions than higher impedance alternatives provide.

Single Zener Diodes Part Context

This part belongs to the MMSZ52xxxT1G series of Zener voltage regulators. These devices serve as an alternative to traditional leadless packages while maintaining small form factors. The series covers a wide voltage range from 2.4 V to 110 V, offering designers flexibility in selecting precise voltage references for various circuit topologies without sacrificing board space efficiency.
