DZ23C6V2-HE3-18

Overview

The DZ23C6V2-HE3-18 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 6.2 V with a standard tolerance of ±5%. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.1 µA at 38 V. Dynamic resistance is specified at 10 Ω (max) at IZT1 and 2 Ω (max) at IZT2. It is AEC-Q101 qualified for automotive applications, supports a junction temperature up to 150 °C, and offers ESD protection exceeding 8 kV (HBM).

Feature Summary

• Dual common cathode configuration within a compact SOT-23 footprint.
• AEC-Q101 qualification ensuring reliability for automotive environments.
• High electrostatic discharge robustness exceeding 8 kV via human body model.
• RoHS-compliant manufacturing process.

Applications

• Voltage reference circuits requiring stable bias points.
• Clamping and protection stages in automotive electronic modules.
• General-purpose voltage regulation in consumer electronics.

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 automotive qualification. Ensure the -18 suffix matches the required 13-inch reel packaging quantity of 10,000 units. Cross-reference the specific datasheet revision to validate electrical parameters against the design requirements before finalizing procurement.

Selection Notes

Select this component when a 6.2 V reference is needed in a small SMD form factor. The HE3 variant is mandatory for automotive projects due to its AEC-Q101 certification. Consider the 5 mA test current and 10 Ω dynamic resistance when designing precision regulation loops. Verify thermal dissipation limits if operating near the upper temperature range.

Part Context

This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V using the E24 grading standard. The DZ23C6V2-HE3-18 specifically denotes the 6.2 V version with automotive qualification and 13-inch tape-and-reel packaging.

Replacement Considerations

Direct substitutes include other DZ23C6V2 variants from Vishay, such as the commercial grade DZ23C6V2-E3-18, provided AEC-Q101 qualification is not required. Other manufacturers offering SOT-23 Zener diodes with similar 6.2 V ratings may be considered after verifying pinout compatibility and electrical parameter alignment.
