PLZ11A-HG3_A/H

Single Zener Diodes Overview

The PLZ11A-HG3_A/H is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features an 11 V nominal Zener voltage with ±3% tolerance and a maximum power dissipation of 500 mW. The device utilizes the ultra-small MicroSMF (DO-219AC) surface-mount package, measuring 2.5 mm in length and 0.6 mm in height. Key electrical specifications include a maximum reverse leakage current of 200 nA at 12 V, a maximum Zener impedance of 18 Ohms, and a forward voltage of 900 mV at 10 mA. It operates within a temperature range of -55°C to 150°C and holds AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Ultra-small low-profile MicroSMF (DO-219AC) package for space-constrained designs
• High thermal stability with a maximum operating junction temperature of 150°C

Single Zener Diodes Procurement Notes

Verify the specific suffix HG3_A/H confirms RoHS compliance and halogen-free status as per Vishay documentation. Confirm the DO-219AC package dimensions match your PCB footprint requirements. Ensure the AEC-Q101 qualification meets your automotive or industrial reliability standards. Check that the ±3% voltage tolerance aligns with your circuit's precision needs. Validate the 500 mW power rating against your expected thermal dissipation conditions.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode is required for precise voltage clamping. The MicroSMF package offers a significant size reduction compared to traditional axial leads. Consider the 11 V nominal voltage and ±3% tolerance for tight regulation requirements. The high operating temperature range supports demanding environmental conditions. Verify compatibility with automated pick-and-place assembly processes due to the small form factor.

Single Zener Diodes Part Context

This part belongs to the PLZ series of silicon planar Zener diodes from Vishay. The series is characterized by its ultra-small footprint and robust performance in discrete semiconductor applications. The PLZ11A variant specifically targets the 11 V market segment within the broader family of voltage reference components. It complements other parts like the PLZ11B and PLZ16C in providing standardized voltage options.

Single Zener Diodes Replacement Considerations

The PLZ11B-HG3_A/H is a confirmed substitute with identical 11 V rating and 500 mW power dissipation but may differ in voltage tolerance specifications. Verify if the tolerance difference impacts your specific application requirements before substitution.
