Overview
The AZ23C33-E3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 33 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and includes ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a test current of 2 mA, a reverse leakage current of 50 µA at 25 V, and a dynamic resistance of 80 Ω.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- ESD capability compliant with AEC-Q101 standards
- RoHS-compliant commercial grade construction
Applications
- Voltage reference circuits requiring dual stable potentials
- Clamping and protection stages in signal processing paths
- Biasing networks in low-power electronic systems
Procurement Notes
Verify the specific ordering code suffix against official Vishay documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure that the component's RoHS compliance status aligns with project requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual common anode topology is required within a compact SOT-23 footprint. Consider the 300 mW thermal limit on standard PCBs and verify that the 33 V nominal voltage fits the target circuit constraints without exceeding the specified operating temperature range.
Part Context
This part belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades and tolerance options, providing designers with standardized components for precision voltage regulation tasks across diverse industrial and consumer electronics applications.
Replacement Considerations
Direct substitutes within the same family include AZ23B33-E3-08 for tighter tolerance or AZ23C33-HE3_A-08 for automotive qualification. Verify pinout compatibility and electrical parameter equivalence before implementing any cross-manufacturer replacements.
