Overview
The onsemi 1N4747A_S00Z is a silicon planar power Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 20 V with a tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 22 Ohms, and a test current of 12.5 mA. It utilizes a DO-41-2 through-hole package.
Feature Summary
- Provides stable voltage regulation at a nominal 20 V level
- Capable of handling up to 1 W of power dissipation
- Operates reliably across an extended temperature range from -65°C to +200°C
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix _S00Z against official onsemi documentation to confirm packaging or tape-and-reel specifications. Ensure the component meets RoHS and REACH requirements as stated in the datasheet. Confirm that the DO-41-2 package dimensions align with your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a 20 V regulation point is required with high thermal stability. The wide operating temperature range makes it suitable for harsh environments. Compare the 22 Ohm Zener impedance against circuit sensitivity requirements. Ensure the 1 W power rating accommodates peak surge currents without exceeding junction temperature limits.
Part Context
This part belongs to the standard 1N47xx series of glass-passivated silicon Zener diodes manufactured by onsemi. These components are widely used in general-purpose electronics for their reliability and standardized performance parameters. The 1N4747A variant specifically targets the 20 V segment of this extensive product line.
Replacement Considerations
Cross-reference with other manufacturers' 1N4747A parts such as those from Microchip Technology (1N4747AUR) or STMicroelectronics. Verify that substitute components match the 20 V nominal voltage, 1 W power rating, and DO-41 package form factor to ensure mechanical and electrical compatibility.
