DZ23C27-HE3_A-08

Overview

The DZ23C27-HE3_A-08 is a small signal silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 27 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and supports a maximum power dissipation of 500 mW. It is AEC-Q101 qualified for automotive applications and offers high ESD protection exceeding 8 kV via the human body model.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• High electrostatic discharge (ESD) capability
• RoHS-compliant construction

Applications

• Voltage regulation in automotive electronics
• Reference voltage generation
• Clamping circuits

Procurement Notes

Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification. Ensure the tape-and-reel quantity matches the required minimum order quantity of 3000 units per reel. Confirm RoHS compliance status if environmental regulations apply to the specific manufacturing batch.

Selection Notes

Select this component when a 27 V reference with ±5 % tolerance is required in an SOT-23 footprint. Consider the 2 mA test current for biasing requirements. Verify thermal management capabilities against the specified junction-to-lead thermal resistance for the intended operating environment.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V. The HE3_A variant specifically denotes AEC-Q101 qualification and RoHS compliance, distinguishing it from the commercial grade E3 variants.

Replacement Considerations

Direct replacements within the same family include other DZ23C27-HE3_A-xx variants with different reel packaging options.
