DZ23C3V6-HE3-08

Overview

The DZ23C3V6-HE3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 3.6 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 90 Ω at this current level. It is AEC-Q101 qualified for automotive applications and supports power dissipation up to 300 mW on an FR-4 board. The component functions as a unidirectional voltage regulator within an operating temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• ESD protection capability exceeding 8 kV via human body model
• RoHS-compliant construction without halogenated substances

Applications

• Voltage reference circuits in automotive electronics
• Clamping and protection against overvoltage transients
• Biasing networks requiring stable low-voltage regulation

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 qualification status. Ensure the specific tape-and-reel quantity matches the required production volume. Confirm RoHS compliance documentation is available for regulatory adherence. Validate the marking code corresponds to the intended voltage rating before assembly.

Selection Notes

Select this component when a 3.6 V regulation point is required in space-constrained designs utilizing the SOT-23 footprint. Consider the 5 mA test current requirement for bias network design. Evaluate the thermal resistance parameters if operation near the upper temperature limit is anticipated. Verify that the ±5 % tolerance meets the circuit's precision requirements.

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 variant specifically denotes RoHS compliance and automotive qualification, distinguishing it from the commercial grade E3 versions.

Replacement Considerations

Direct substitutes include other DZ23 series variants with identical voltage ratings but different packaging or qualification levels. Cross-brand replacements must match the SOT-23 pinout, 3.6 V nominal voltage, and power dissipation limits.
