1N5227B TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5227B TR PBFREE is a silicon Zener diode in the DO-35 axial through-hole package. It provides a nominal Zener voltage of 3.6 V with a ±5% tolerance, tested at 20 mA. The device dissipates 500 mW and operates within a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum Zener impedance of 24 Ω, a maximum reverse current of 15 μA at 1.0 V, and a forward voltage of 1.2 V max at 200 mA. The 'TR' suffix indicates tape and reel packaging, while 'PBFREE' denotes lead-free plating.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation for industrial, commercial, entertainment, and computer applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes required for your application. The 'TR' designation confirms tape and reel packaging, which differs from bulk units. Confirm that 'PBFREE' aligns with your assembly's lead-free requirements. Ensure the DO-35 form factor fits your board layout constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is needed in a standard axial package. The ±5% tolerance suits general-purpose regulation tasks. Verify that the 500 mW power rating accommodates your circuit's dissipation needs. Consider the low reverse leakage current if noise sensitivity is a primary design constraint.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5278B series of 500 mW silicon Zener diodes. The series covers a wide voltage range from 2.4 V to 170 V. All devices share the same DO-35 mechanical outline and standardized electrical testing conditions. The 'B' suffix consistently indicates the ±5% voltage tolerance class across the entire family.
