Overview
The AZ23C18-AU_R1_000A1 is a dual surface mount Zener diode manufactured by Panjit International Inc. It features a common anode configuration within an SOT-23-3 package. The nominal Zener voltage is 18 V, with a maximum Zener impedance of 50 Ohms at a test current of 5 mA. Maximum reverse leakage current is specified as 100 nA at 14 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 holds AEC-Q101 qualification.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
- Qualified for automotive applications under the AEC-Q101 standard.
- Manufactured using lead-free materials compliant with EU RoHS directives and halogen-free molding compounds.
Applications
- Voltage regulation in automotive electronic systems
- Clamping circuits for transient voltage suppression
- Reference voltage generation in low-power consumer electronics
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number and ordering suffix with official datasheets. Confirm that the received units match the specified SOT-23-3 package dimensions and marking codes. Ensure compliance with environmental standards such as RoHS and AEC-Q101 requirements relevant to the intended deployment environment.
Selection Notes
Select this component when a dual Zener solution with a shared anode is required in a compact SMD footprint. The 300 mW power rating and 18 V breakdown voltage define its operational limits. Verify that the 50 Ohm impedance and 100 nA leakage specifications align with the circuit's precision and noise requirements.
Part Context
This part belongs to the AZ23C2V4-AU series, which encompasses dual Zener diodes with voltages ranging from 2.4 V to 36 V. All members of this series share identical mechanical characteristics, including the SOT-23 case and 300 mW power dissipation capability, differing only in their specific Zener voltage ratings and corresponding electrical parameters.
Replacement Considerations
Direct replacements must maintain the dual common anode topology, SOT-23-3 package, and 18 V nominal voltage. Verify that substitute components meet or exceed the 300 mW power dissipation and AEC-Q101 automotive qualification standards to ensure functional equivalence.
