1N5230B-TAP

Single Zener Diodes Overview

The Vishay 1N5230B-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) 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 parameters include a maximum dynamic impedance of 19 Ω, a reverse leakage current of 5 µA at 2 V, and a forward voltage of 1.1 V at 200 mA. It supports junction temperatures up to 175 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging details. The TAP suffix indicates an ammo pack configuration containing 10,000 units per reel. Ensure compatibility with required thermal resistance and lead length specifications during integration.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V reference with ±5% accuracy is required in an axial through-hole format. Consider the 19 Ω dynamic impedance and 500 mW power dissipation limits relative to circuit load conditions. Verify that the operating temperature range aligns with system requirements.

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 voltage range from 2.4 V to 75 V. The 1N5230 variant specifically targets applications requiring a 4.7 V breakdown voltage within this standardized lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5230 equivalents or Vishay's TZM5230 MiniMELF version if surface mount space is constrained. Verify pinout and package dimensions match before substitution.
