Overview
The AZ23C27-AU_R1_000A1 is a dual surface mount Zener diode from the AZ23C series manufactured by Panjit International Inc. It features a common anode configuration within an SOT-23 molded plastic package. The nominal Zener voltage is 27 V, with a maximum Zener impedance of 80 Ohms and a maximum reverse leakage current of 100 nA at 20 V. The device supports a power dissipation rating of 300 mW and operates within a junction temperature range of -55°C to +150°C. It is AEC-Q101 qualified and complies with EU RoHS directives.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
- Automotive-grade reliability certified under the AEC-Q101 standard.
- Halogen-free green molding compound compliant with IEC61249 standards.
Applications
- Voltage reference circuits requiring dual independent references.
- Clamping applications in automotive electronics systems.
- Protection against load dump surges in vehicle infotainment and body electronics.
Procurement Notes
Verify the specific part number suffix against official distributor catalogs to ensure correct packaging quantities and reel specifications. Confirm that the component meets the required AEC-Q101 qualification status for your specific application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution with a shared anode terminal is required in a compact SOT-23 footprint. Ensure the 300 mW power dissipation limit accommodates the thermal conditions of the target PCB layout. Verify that the 27 V nominal voltage aligns precisely with the circuit's clamping or reference requirements.
Part Context
This component belongs to the AZ23C2V4-AU series, which covers nominal Zener voltages ranging from 2.4 V to 36 V. All devices in this series share identical mechanical dimensions and electrical test conditions, differing only in their specific breakdown voltage characteristics and marking codes.
Replacement Considerations
Direct replacements must match the SOT-23-3 package, 300 mW power rating, and dual common anode configuration. Verify that any substitute component holds equivalent AEC-Q101 automotive qualification and maintains similar impedance and leakage parameters at 27 V.
FAQ
