BZD27B160P-HE3-18

Single Zener Diodes Overview

The BZD27B160P-HE3-18 is a silicon planar Zener diode from the Vishay BZD27B series, housed in an SMF (DO-219AB) surface-mount package. It features a nominal Zener voltage of 160 V with a ±2% tolerance and operates at a test current of 5 mA. The device supports a maximum power dissipation of 800 mW at 30 °C ambient temperature and withstands non-repetitive peak surge currents up to 130 A. It is qualified under AEC-Q101 standards for automotive applications.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix HE3-18 corresponds to the specific reel packaging and AEC-Q101 qualification status required for your assembly line. Confirm compliance with RoHS directives and ensure the component matches the DO-219AB footprint dimensions during procurement validation.

Single Zener Diodes Selection Notes

Select this component when a stable 160 V reference is needed in space-constrained designs. The SMF package offers a compact alternative to larger through-hole options while maintaining robust thermal performance. Ensure the application current does not exceed the specified test current to maintain accuracy within the tight tolerance band.

Single Zener Diodes Part Context

This part belongs to the BZD27B series, which provides a wide range of breakdown voltages from 3.6 V to 200 V. The series is characterized by its low profile and compatibility with standard SOD-123W reflow soldering profiles, making it suitable for automated surface-mount manufacturing processes.

Single Zener Diodes Replacement Considerations

Substitutes must match the 160 V nominal voltage, SMF (DO-219AB) package outline, and AEC-Q101 qualification. Verify that any replacement diode meets the same surge current handling capabilities and thermal resistance specifications to ensure circuit integrity.
