1N4736A_S00Z

Overview

The onsemi 1N4736A_S00Z is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W at an ambient temperature of 25°C. It utilizes the DO-201AD axial leaded package, suitable for through-hole mounting. Key electrical parameters include a maximum reverse leakage current of 10 µA at the test voltage and a maximum Zener impedance of 3.5 Ω at the test current of 37 mA. The component operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation using silicon planar technology
• Capable of handling high surge currents for transient protection
• Offers low dynamic impedance for precise voltage referencing

Applications

• Voltage regulation in power supply circuits
• Voltage reference sources in measurement equipment
• Overvoltage protection in electronic systems

Procurement Notes

Verify the specific suffix S00Z against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure that the procurement channel provides valid traceability for the component lot. Cross-reference the part number with the latest datasheet to confirm availability and any potential obsolescence notices from onsemi before finalizing orders.

Selection Notes

Select this component when a 6.8 V regulation point is required with a 1 W power rating. The DO-201AD package is appropriate for applications requiring robust mechanical stability and high thermal capacity. Consider the 3.5 Ω impedance specification for applications sensitive to voltage variations under load changes. Ensure the operating environment stays within the specified temperature limits for reliable performance.

Part Context

This component belongs to the standard 1N47 series of Zener diodes, widely used in general-purpose electronics. The 1N4736A designation specifically identifies the 6.8 V variant within this family. The S00Z suffix typically denotes specific packaging or tape-and-reel configurations provided by onsemi, distinguishing it from bulk packaged equivalents while maintaining identical electrical characteristics.

Replacement Considerations

Direct replacements include other manufacturers' 1N4736A parts meeting the same JEDEC outline and electrical specifications. Verify that substitute components match the 6.8 V nominal voltage, 1 W power rating, and DO-201AD package dimensions. Ensure compatibility with the circuit's thermal and electrical requirements.
