Overview
The AZ23B30-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 30 V with a tight ±2 % tolerance. The device operates at a test current of 2 mA and dissipates up to 500 mW on lead or 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.05 μA at 17 V and a dynamic resistance of 80 Ω at the test current.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- High ESD protection capability exceeding 8 kV via human body model
- Green commercial grade construction compliant with RoHS standards
Applications
- Voltage reference circuits requiring precise dual-channel regulation
- ESD protection interfaces for sensitive signal lines
- Clamping applications in low-power consumer electronics
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel size and tape specifications. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Confirm compliance requirements such as RoHS status prior to finalizing purchase orders.
Selection Notes
Select this component when a dual Zener array with high precision is required in a compact footprint. The ±2 % tolerance makes it suitable for applications demanding strict voltage accuracy. Consider the thermal resistance values when designing PCB layouts to ensure power dissipation limits are not exceeded during operation.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2 % voltage tolerance compared to the standard ±5 % 'C' variant within the same family.
Replacement Considerations
AZ23C30-G3-08 (Same package, ±5% tolerance)
FAQ
What is the marking code for the AZ23B30-G3-08?
The marking code for this device is DF6.
What is the maximum operating temperature?
The maximum operating junction temperature is +150 °C.
How does the power dissipation change based on mounting?
Power dissipation is rated at 500 mW when measured with RthJL = 250 K/W, but reduces to 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
