1N5230B BK PBFREE

Single Zener Diodes Overview

The 1N5230B BK PBFREE is a silicon unidirectional voltage regulator diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 4.7 V with a maximum dynamic impedance of 19 Ω. The device is rated for a maximum power dissipation of 0.5 W and operates within a temperature range of -65°C to 200°C. Packaged in the DO-35 axial through-hole case, it maintains a voltage tolerance of ±5% at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single Zener junction structure.
• Designed for high thermal stability across an extended operating temperature range.
• Constructed with a rugged axial leaded package suitable for through-hole mounting.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for signal lines.

Single Zener Diodes Procurement Notes

Verify the specific suffix BK against manufacturer documentation to confirm bulk packaging specifications. Confirm RoHS compliance status directly with Central Semiconductor Corp as regulatory data may vary by production batch. Ensure the DO-35 package dimensions match your PCB layout requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulation point is required in a through-hole design. The 500 mW power rating supports moderate current loads without external heat sinking. Verify that the 19 Ω dynamic impedance meets the noise and stability requirements of your specific application circuit compared to lower impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the standard 1N52 series of Zener diodes produced by Central Semiconductor Corp. The series offers various voltage ratings within the same DO-35 mechanical footprint. The BK suffix typically denotes bulk packaging, distinguishing it from tape-and-reel variants used in automated assembly processes.

Single Zener Diodes Replacement Considerations

The 1N5230B TR PBFREE serves as a parameter-equivalent alternative offering identical electrical characteristics but utilizing tape-and-reel packaging instead of bulk. Other manufacturers producing the 1N5230B specification may provide compatible substitutes if sourcing flexibility is required.
