BZX84C2V2-HE3_A-08

Single Zener Diodes Overview

The BZX84C2V2-HE3_A-08 is a single Zener diode manufactured by Vishay Semiconductors, designed for surface-mount applications in the SOT-23-3 package. It features a nominal Zener voltage of 2.2 V with a power dissipation rating of 300 mW. The device exhibits a maximum Zener impedance (Zzt) of 120 Ohms and a reverse leakage current of 100 µA at 1 V. It supports an operating junction temperature up to 150°C and holds AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Compact SOT-23-3 surface-mount packaging for space-constrained designs
• Low voltage regulation capability suitable for precision reference circuits

Single Zener Diodes Applications

• Voltage reference sources in automotive electronic control units
• Overvoltage protection for low-voltage signal lines
• Clamping applications in portable battery-powered devices

Single Zener Diodes Procurement Notes

Verify the specific suffix _A-08 against the manufacturer's latest datasheet to confirm package variant and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment due to the small SOT-23-3 footprint. Cross-reference the AEC-Q101 certification status for your specific supply chain requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 2.2 V reference is required in an automotive or industrial environment. The 300 mW power rating allows for moderate current handling in compact layouts. Consider the 120 Ohm impedance for noise-sensitive applications where lower dynamic resistance might be necessary. Verify thermal management capabilities given the 150°C junction limit.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX84 series of single Zener diodes, which are widely used for general-purpose voltage regulation and protection. The HE3 designation indicates a high-efficiency planar die design, while the _A-08 suffix typically denotes specific packaging configurations such as cut tape or reel options within the standard product line.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay BZX84C2V2 variants with compatible pinouts and electrical characteristics. Ensure any replacement maintains the same AEC-Q101 qualification if automotive compliance is mandatory. Verify that alternative packages match the SOT-23-3 footprint dimensions for seamless PCB integration.
