Overview
The DZ23C16-HE3_A-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 16 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 0.05 µA at 17 V. Dynamic resistance is specified at 40 Ω (at IZT1) and 170 Ω (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 via the human body model.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant HE3_A material categorization
Applications
- Automotive voltage regulation circuits
- General-purpose voltage reference applications
- Protection against electrostatic discharge events
Procurement Notes
Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification status. Confirm the specific tape-and-reel packaging format required for automated assembly processes. Ensure compliance with RoHS directives as defined by the manufacturer's material categorization documentation before finalizing procurement specifications.
Selection Notes
Select this component when a 16 V reference with ±5 % tolerance is required in an SOT-23 footprint. Verify that the 5 mA test current aligns with the target circuit design. Consider the dynamic resistance values for signal integrity requirements. Confirm thermal management capabilities within the intended operating temperature range of -55 °C to +150 °C.
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 DZ23C16 variant specifically targets the mid-range voltage segment, offering a balance between low leakage current and moderate dynamic impedance suitable for precision analog applications.
Replacement Considerations
Direct substitutes within the same family include other DZ23C16 variants such as DZ23C16-E3-08 or DZ23C16-HE3_A-18, provided the AEC-Q101 qualification and reel size match the application requirements.
