BZD27B10P-HE3-18

Single Zener Diodes Overview

The BZD27B10P-HE3-18 is a silicon planar Zener diode from Vishay, housed in the SMF (DO-219AB) surface-mount package. It features a nominal Zener voltage of 10 V with a ±2% tolerance and a test current of 50 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 20 A. Operating within a junction temperature range of -65 °C to +175 °C, it meets AEC-Q101 automotive qualification standards.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• Low leakage current and excellent stability characteristics
• Surge current specification capability for transient protection
• Compatible with standard SOD-123W and SOD-123F package outlines

Single Zener Diodes Applications

• Voltage regulation circuits requiring high stability
• Transient voltage suppression in automotive electronics
• Reference voltage sources in precision measurement equipment
• Overvoltage protection for sensitive semiconductor components

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 automotive qualification status. Ensure the trailing -18 indicates the correct 10,000 units per reel packaging format. Cross-reference the specific datasheet revision against your design requirements to confirm compliance with RoHS directives and material categorization standards before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when an exact 10 V breakdown voltage with tight ±2% tolerance is required. The SMF package offers a low-profile solution suitable for automated placement processes. Consider the thermal impedance characteristics if operating near the maximum junction temperature limit. Verify that the 800 mW power dissipation rating aligns with the expected thermal environment of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the BZD27B series of Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of breakdown voltages from 3.6 V to 200 V. All devices share the same SMF (DO-219AB) surface-mount package geometry. The HE3 variant specifically denotes high reliability grade components compliant with automotive industry standards.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay BZD27B series parts with identical voltage ratings but different packaging suffixes, such as BZD27B10P-HE3_A08. Non-Vishay equivalents must match the DO-219AB footprint, 10 V nominal voltage, and ±2% tolerance specifications.
