1N5230B_S00Z

Single Zener Diodes Overview

The onsemi 1N5230B_S00Z is a silicon unidirectional Zener voltage regulator diode housed in the DO-35 glass axial leaded package. It provides a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device supports a maximum steady-state power dissipation of 500 mW at temperatures up to 75°C, requiring derating above this threshold. Key electrical characteristics include a maximum dynamic impedance of 19 Ω and a reverse leakage current of 5 µA. It operates within a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• High stability and low noise performance suitable for precision regulation
• Compact axial leaded form factor for through-hole mounting

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix _S00Z against official manufacturer documentation to confirm exact marking codes and compliance status. Ensure the procurement channel sources from authorized distributors to guarantee authenticity. Confirm that the DO-35 package dimensions match the target PCB footprint requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, high-reliability axial Zener diode is required. The 500 mW power rating distinguishes it from lower-power surface mount alternatives. Verify that the 4.7 V nominal voltage aligns with the circuit's regulation needs and that the ±5% tolerance meets the design specifications.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes licensed by onsemi. These devices are widely recognized for their robustness in harsh environments due to the hermetic glass seal. The series covers a broad range of voltage values, with the 1N5230B specifically targeting the 4.7 V regulation segment.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N5230B, Diodes Inc. 1N5230B-13, LRC 1N5230B, and Tak Cheong 1N5230BRA1. All listed parts share the same 4.7 V Zener voltage, 500 mW power rating, and DO-35 package style.
