BZD27C20P-HE3-08

Single Zener Diodes Overview

The BZD27C20P-HE3-08 is a silicon planar Zener diode from Vishay, housed in the SMF (DO-219AB) surface-mount package. It features a nominal Zener voltage of 20 V with a range of 18.8 to 21.2 V at a test current of 25 mA. The device supports a maximum power dissipation of 2300 mW and handles a non-repetitive peak surge power of 300 W. It operates within a junction temperature range of -65 °C to +175 °C and meets AEC-Q101 automotive qualification standards.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive applications
• Low leakage current and excellent stability
• Compatible with wave and reflow soldering processes
• Meets MSL level 1 and JESD 201 class 2 whisker test requirements

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection for electronic components
• Clamping applications in automotive electronics

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific HE3 suffix for AEC-Q101 qualification. Confirm the tape and reel configuration corresponds to the required units per reel. Ensure the component complies with RoHS directives and material categorization standards before integration into production assemblies.

Single Zener Diodes Selection Notes

Select this component when an automotive-grade Zener diode with specified surge current capabilities is required. The low profile SMF package suits space-constrained designs. Verify that the 20 V nominal voltage aligns with the circuit's regulation or clamping thresholds under expected operating temperatures.

Single Zener Diodes Part Context

This part belongs to the BZD27C Series of Zener diodes designed for general-purpose and automotive use. The series offers a wide voltage range from 3.6 V to 200 V in a compact surface-mount form factor. The HE3 variant specifically denotes compliance with automotive reliability standards, distinguishing it from the commercial grade E3 version.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZD27C20P variants from Vishay, such as the E3-08 commercial grade version, provided automotive qualification is not mandatory. Cross-brand replacements require matching the SMF package, 20 V Zener voltage, and surge power ratings.
