2N5226 TRE PBFREE

Overview

The 2N5226 TRE PBFREE is a Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 3.3 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to 150°C. It utilizes the SOD-123 surface mount package. Key electrical characteristics include a maximum impedance of 28 Ohms and a reverse leakage current of 25 µA at 1 V.

Feature Summary

• Provides stable voltage regulation at 3.3 V for circuit protection and reference applications
• Designed for surface mount assembly using the compact SOD-123 package
• Capable of operating in extreme environments from -65°C to 150°C

Applications

• Voltage reference circuits
• Over-voltage protection
• Clamping applications

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives as indicated by the PBFREE designation. Cross-reference the Mouser part number 610-CMHZ5226BTRPBFREE or DigiKey identifiers for accurate sourcing and availability checks.

Selection Notes

Select this component when a 3.3 V Zener reference is required in a small surface-mount footprint. Consider the 500 mW power rating and 28 Ohm impedance for load regulation requirements. Verify that the SOD-123 package dimensions fit the PCB layout constraints and that the operating temperature range meets the environmental specifications.

Part Context

This part belongs to the Central Semiconductor Zener diode family, specifically designed for general-purpose voltage regulation. It is distinct from other series like the CMPZ line which may offer different power ratings or packages. The TRE PBFREE suffix indicates a lead-free, tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.
