1N4734A_S00Z

Overview

The onsemi 1N4734A_S00Z is a silicon Zener diode with a nominal voltage of 5.6 V and a power dissipation rating of 1 W. It features a ±5% tolerance and operates within a temperature range of -65 °C to +175 °C. The device utilizes a DO-41 axial through-hole package, measuring 2.6 mm in diameter and 4.1 mm in length. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 2 V and a Zener impedance of 5 Ohms.

Feature Summary

• Provides stable voltage regulation at 5.6 V for circuit protection applications
• Operates reliably across an extended industrial temperature range up to 175 °C
• Utilizes a robust glass passivated junction for enhanced durability

Applications

• Voltage reference circuits requiring precise 5.6 V levels
• Overvoltage protection in low-power electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's obsolete status. Confirm manufacturing date codes and lot traceability to ensure compliance with specific project requirements. Review available substitute options from active production lines if long-term supply stability is critical for the intended application lifecycle.

Selection Notes

Select this component when a standard 5.6 V Zener characteristic is required in a through-hole configuration. Ensure the design accommodates the 1 W power dissipation limit under worst-case thermal conditions. Verify that the DO-41 package dimensions fit the target PCB layout constraints before finalizing the bill of materials.

Part Context

This component belongs to the widely recognized 1N4734 series of Zener diodes, historically manufactured by multiple semiconductor vendors including Motorola and Vishay. The onsemi variant maintains the standard electrical specifications associated with this industry-standard part number, ensuring compatibility with legacy designs originally specified using generic 1N4734A references.

Replacement Considerations

The 1N4734A_S00Z is officially classified as obsolete by onsemi. Engineers should evaluate alternative sources such as the 1N4734A-TR from Vishay or the 1N4734A,133 from Nexperia for active procurement needs.
