1N5230BDO35

Single Zener Diodes Overview

The Microsemi Corporation 1N5230BDO35 is a silicon unidirectional Zener voltage regulator diode housed in a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. It provides a nominal Zener voltage of 4.7 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates at a maximum power dissipation of 0.5 W and features a test current of 20 mA. Electrical characteristics include a maximum reverse leakage current of 19 μA at 4.3 V, a maximum dynamic impedance of 19 Ω at 0.25 mA, and a temperature coefficient of ±0.030 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation
• Standardized JEDEC registration ensuring broad component compatibility
• Low capacitance design suitable for high-frequency applications
• Inherent radiation hardness per MicroNote 050 specifications

Single Zener Diodes Applications

• Voltage regulation in precision electronic circuits
• Overvoltage protection for sensitive semiconductor components
• Reference voltage generation in measurement instrumentation

Single Zener Diodes Procurement Notes

Verify that the ordering part number includes the correct suffix to confirm specific electrical tolerances and compliance status. Confirm the manufacturer source matches Microsemi Corporation or an authorized distributor. Ensure the package type corresponds to the DO-35 axial lead configuration required for the intended mounting method. Check for RoHS compliance if restricted substances are prohibited in the assembly process.

Single Zener Diodes Selection Notes

Select this component when a stable 4.7 V reference is required within a low-power environment. The DO-35 package supports through-hole mounting on printed circuit boards. Consider the thermal resistance and derating curves if operating near the maximum power dissipation limit. Verify that the ±5% voltage tolerance meets the system's accuracy requirements without needing tighter specification variants.
