Overview
The AZ23C36-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It provides two independent Zener elements with a nominal voltage of 36 V and a tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and supports a maximum power dissipation of 300 mW on an FR-4 board. Electrical characteristics include a reverse leakage current of 50 nA at 27 V and a dynamic resistance of 87 Ω at a test current of 2 mA.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Zener voltages graded according to international E24 standard
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual stable potentials
- Clamping applications for signal lines
- Protection stages in automotive electronics
Procurement Notes
Verify that the ordering code matches the required tolerance and qualification level. Confirm the suffix indicates AEC-Q101 qualification if automotive grade is needed. Ensure the reel quantity aligns with production requirements before finalizing orders.
Selection Notes
Select this component when a dual Zener solution is necessary in a compact surface-mount footprint. Consider the thermal resistance and ambient operating conditions to ensure power dissipation limits are not exceeded during continuous operation.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage options ranging from 2.2 V to 75 V in the SOT-23 package, providing standardized grading for consistent performance across different voltage ratings.
