PDZ11B-AU_R1_000A1

Single Zener Diodes Overview

The PDZ11B-AU_R1_000A1 is an 11 V Zener diode manufactured by Panjit International Inc., designed for surface-mount applications in the SOD-323 (SC-90) package. It features a maximum power dissipation of 400 mW and a tight voltage tolerance of ±2%. The device exhibits a maximum dynamic impedance of 10 ohms and maintains a reverse leakage current of no more than 100 nA at 8 V. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 qualification for automotive reliability standards.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a nominal Zener voltage of 11 V and a tight manufacturing tolerance of ±2%.
• Engineered for high-reliability environments through AEC-Q101 automotive grade qualification.
• Offers low leakage current characteristics, ensuring minimal power loss in standby or high-impedance states.

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronic control units
• Over-voltage protection stages in vehicle sensor interfaces
• Clamping applications in automotive data communication lines

Single Zener Diodes Procurement Notes

Verify the specific suffix AU_R1_000A1 against the manufacturer's latest datasheet to confirm packaging configuration and lot traceability. Ensure that the AEC-Q101 qualification status aligns with your system's automotive reliability requirements. Cross-reference the SOD-323 footprint dimensions with your PCB design guidelines to guarantee mechanical compatibility during assembly.

Single Zener Diodes Selection Notes

Select this component when a stable 11 V reference is required in space-constrained automotive designs. The SOD-323 package offers a compact solution compared to larger axial leads. Consider the 400 mW power rating for thermal management in dense circuit boards. The ±2% tolerance makes it suitable for precision applications where standard 5% or 10% Zeners would introduce unacceptable error margins.

Single Zener Diodes Part Context

This part belongs to Panjit's PDZ11B series of single Zener diodes. The AU_R1_000A1 designation indicates a specific reel-based packaging format intended for automated surface-mount assembly processes. It shares the core electrical specifications of the base PDZ11B model but is optimized for high-volume manufacturing integration in the consumer and automotive electronics sectors.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 11 V, 400 mW Zener diodes in the SOD-323 package from manufacturers such as ON Semiconductor or Vishay, provided they meet the AEC-Q101 requirement. Verify that alternative parts maintain the same ±2% tolerance and dynamic impedance characteristics to ensure circuit performance parity.
