1N4745A_S00Z

Overview

The onsemi 1N4745A_S00Z is a 16V Zener diode with a 1W maximum power dissipation. It features a 5% voltage tolerance and operates within a temperature range of -65°C to +200°C. The device utilizes a DO-41 axial leaded package and hermetically sealed glass construction.

Feature Summary

• Hermetically sealed glass construction for environmental protection
• High thermal stability supporting extended operating temperatures
• Compression bonded design ensuring mechanical reliability

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific suffix S00Z against official onsemi documentation to confirm exact packaging configuration and compliance status. Ensure the component matches the required hermetic sealing specifications for your application environment. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a robust, high-reliability 16V reference is needed in harsh environments. The DO-41 package suits through-hole mounting requirements. Consider the 5% tolerance if tighter precision is not critical. Evaluate thermal derating requirements for applications exceeding standard temperature limits.

Part Context

This part belongs to the 1N47xxA series of 1-watt Zener diodes. These devices are widely used for general-purpose voltage regulation. The 'A' suffix typically denotes a 5% tolerance band. The series offers a broad range of voltage options within the same standardized package format.

Replacement Considerations

Equivalent parts include Fairchild 1N4745A and Microsemi MV1N4745CP. Verify pinout compatibility and ensure replacement devices meet the same hermetic sealing and power dissipation ratings.
