1N5227B

Single Zener Diodes Overview

The onsemi 1N5227B is a silicon voltage regulator diode housed in a DO-35 axial lead glass package. It provides a nominal Zener voltage of 3.6 V with a tolerance of ±5%. The device dissipates up to 500 mW at 25°C, derating by 4.0 mW/°C above this temperature. Electrical characteristics include a maximum Zener impedance of 24 Ω and a reverse leakage current of 15 µA at 1.0 V. The component operates within a junction temperature range of −65°C to +200°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging format, as bulk bags and tape-and-reel options exist for this part number. Ensure compliance with RoHS and REACH requirements by checking the product status listed in the datasheet. Confirm that the supplier provides traceable documentation matching the exact device code markings specified for the 1N5227B.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required with tight tolerance constraints. The DO-35 package suits through-hole designs where moderate power dissipation is manageable. Evaluate thermal conditions carefully, as the device requires derating above 50°C. Consider the negative temperature coefficient for applications operating across wide ambient temperature ranges.

Single Zener Diodes Part Context

This device belongs to the 1N5221B through 1N5252B series of 0.5 W Zener diodes manufactured by onsemi. The series covers a voltage range from 2.4 V to 24.0 V in standard 5% tolerances. These components utilize epitaxial planar technology within a glass axial-lead case, designed for general-purpose voltage regulation tasks in commercial and industrial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5227B equivalents, such as those from Central Semiconductor or Microsemi, ensuring identical electrical parameters and mechanical dimensions are met before substitution.
