1N5230B-T

Single Zener Diodes Overview

The Vishay 1N5230B-T is a silicon planar power Zener diode in the DO-35 axial package. It provides a nominal Zener voltage of 4.7 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical characteristics include a maximum dynamic resistance of 19 Ω, a reverse leakage current of 5 µA at 2 V, and a typical temperature coefficient of 0.03 %/K.

Single Zener Diodes Procurement Notes

Verify that the ordering code suffix matches the required packaging format. Confirm the specific tolerance designation aligns with circuit requirements. Ensure lead length and thermal management parameters are considered during integration. Validate compliance documentation against regional standards before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V reference is needed in an axial through-hole configuration. Consider the 500 mW power dissipation limit and the 175 °C junction temperature rating. Evaluate the 19 Ω dynamic impedance for load regulation needs. Compare against MiniMELF or SOT-23 variants if board space constraints require surface mount solutions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of voltages from 2.4 V to 75 V. The 'B' suffix indicates the standard ±5% tolerance class available in the DO-35 package.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay family include other 1N52xx series devices with matching voltage ratings. Cross-manufacturer equivalents must be verified for identical pinout, power dissipation, and package dimensions.
