Overview
The Vishay AZ23B2V2-E3-18 is a silicon planar Zener diode array configured as a common anode pair, housed in an SOT-23 surface-mount package. It provides two independent Zener channels with a nominal voltage of 2.2 V and a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW on lead-mounted applications or 300 mW on FR-4 boards. Electrical characteristics include a maximum reverse leakage current of 1 μA at 1 V and a dynamic impedance of 120 Ω at the test current of 5 mA.
Feature Summary
- Dual-channel common anode configuration for space-efficient circuit design
- Tight voltage tolerance of ±2% for precise reference applications
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant commercial grade construction
Applications
- Voltage reference circuits requiring dual low-voltage rails
- Overvoltage protection for sensitive input lines
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape width and reel quantity specifications. Ensure that the component meets all applicable environmental compliance standards required for the intended manufacturing process before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel Zener solution with high precision is required in a compact footprint. Consider the thermal resistance values and power derating curves if operating near the maximum junction temperature limits in enclosed environments.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers a wide range of standardized voltages following the E24 standard, available in both single and dual configurations. The 'B' designation indicates the tighter ±2% voltage tolerance variant compared to the standard ±5% 'C' version.
