Overview
The DZ23C36-HE3_A-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 36 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum dynamic resistance of 87 Ω at this current level. Reverse leakage current is limited to 0.05 μA when tested at 27 V. The component is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV via the human body model. It supports power dissipation up to 500 mW on leads and 300 mW on FR-4 boards, functioning within a temperature range of -55 °C to +150 °C.
Feature Summary
- Automotive-grade reliability through AEC-Q101 qualification
- Robust electrostatic discharge protection capability
- RoHS-compliant construction with lead-free soldering compatibility
Applications
- Voltage reference circuits in automotive electronics
- ESD protection for sensitive signal lines
- Overvoltage clamping in consumer devices
Procurement Notes
Verify that the ordering suffix matches HE3_A-18 to confirm AEC-Q101 qualification and reel packaging specifications. Cross-reference the manufacturer datasheet document number 86346 to ensure compliance with the latest revision standards before finalizing procurement orders.
Selection Notes
Select this component when a 36 V Zener voltage with ±5 % tolerance is required in an SOT-23 footprint. Ensure the application environment stays within the specified operating temperature range and consider the thermal resistance values if mounting on FR-4 substrates without adequate heat sinking.
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, utilizing silicon planar technology. The specific HE3_A suffix indicates automotive qualification, while the -18 suffix denotes tape-and-reel packaging on a 13-inch reel.
Replacement Considerations
Direct replacements must match the 36 V nominal voltage, ±5 % tolerance, and SOT-23-3 package. Verify that alternative components also meet AEC-Q101 requirements if automotive usage is intended. Check dynamic resistance and leakage current specifications to ensure circuit performance parity.
