1N5230B_T26A

Single Zener Diodes Overview

The onsemi 1N5230B_T26A 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 is rated for a maximum steady-state power dissipation of 500 mW at ambient temperatures up to 75°C, requiring derating above this threshold. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a dynamic impedance of 19 Ω at the test current of 20 mA. The component supports an operating temperature range from -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
• Metallurgically bonded die structure for enhanced reliability

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix _T26A against official manufacturer documentation to confirm tape and reel specifications or lot traceability requirements. Ensure compatibility with existing PCB footprints designed for the standard DO-35 package dimensions. Cross-reference datasheets for thermal derating curves relevant to your specific mounting conditions.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing and high-temperature operation up to 200°C are required. The 500 mW power rating and 4.7 V nominal voltage make it suitable for low-power regulation tasks. Compare against surface-mount alternatives like MMSZ5230BT1G if board space constraints necessitate SMD packages.

Single Zener Diodes Part Context

This part belongs to the 1N52 series of Zener diodes licensed by onsemi. The series offers various voltage options within the same DO-35 hermetic glass package format. These components are widely used in industrial and military applications where long-term stability and radiation hardness are critical factors.
