1N5230B

Single Zener Diodes Overview

The Microchip Technology 1N5230B is a 4.7 V Zener diode with a 5% voltage tolerance, housed in a DO-35 glass axial-lead package. It dissipates 500 mW at 25°C and operates from -65°C to +175°C. The device features a maximum reverse current of 19 µA at 3.3 V, a Zener impedance of 19 Ω at 1 mA, and a temperature coefficient of ±0.030 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction
• Voltage regulation across broad operating ranges
• Minimal capacitance for high-frequency stability

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection networks
• Temperature-compensated biasing applications

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., e3) against the datasheet to confirm RoHS compliance and plating finish. Ensure the ordering prefix matches required military screening levels if applicable. Confirm that the DO-35 package dimensions align with the target PCB footprint before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 4.7 V reference is required within a low-power environment. The tight 5% tolerance ensures accuracy without requiring post-assembly trimming. Verify that the thermal resistance characteristics support the expected power dissipation under worst-case ambient conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener regulators. The series provides a wide selection of voltages from 2.4 V to 200 V in standard DO-35 packages. It serves as a fundamental discrete semiconductor solution for basic voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Cross-reference JEDEC registered equivalents or other manufacturers' 1N5230B parts. Verify that replacement units match the 4.7 V nominal voltage, 5% tolerance, and DO-35 package constraints.
