Overview
The AZ23C28_R1_00001 is a dual surface mount Zener diode from the AZ23C2V4 series manufactured by Panjit International Inc. It features a common anode configuration within an SOT-23 molded plastic case. The nominal Zener voltage is 28 V, with a maximum Zener impedance of 80 Ohms at a test current of 5 mA and a maximum reverse leakage current of 100 nA at 22 V. The device supports a power dissipation rating of 300 mW and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common anode package for space-efficient circuit design.
- Compliant with EU RoHS 2011/65/EU directives and utilizes halogen-free green molding compound.
Applications
- Voltage reference circuits requiring dual independent references.
- Clamping applications for transient voltage suppression.
- Automated insertion processes in surface mount assembly lines.
Procurement Notes
Verify the specific suffix against official documentation to confirm packaging details. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors before procurement. Ensure the ordering code matches the exact electrical characteristics required for the target application.
Selection Notes
Select this component when a dual Zener configuration with a common anode is required in a compact SOT-23 footprint. Verify that the 300 mW power dissipation rating and 80 Ohm impedance meet the circuit's thermal and performance constraints. Ensure the operating junction temperature range aligns with the environmental conditions of the final assembly.
Part Context
This part belongs to the AZ23C2V4 series, which encompasses dual Zener diodes with voltages ranging from 2.4 V to 51 V. All members of this series share the same physical SOT-23 package dimensions and mechanical data, differing primarily in their specific Zener voltage ratings and associated marking codes.
Replacement Considerations
Direct replacements must match the SOT-23-3 package, 300 mW power rating, and common anode configuration. Verify that substitute components offer equivalent Zener impedance and leakage current specifications at 28 V to ensure circuit compatibility.
FAQ
