Overview
The AZ23C27 is a dual common anode Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-23 package. It features a nominal Zener voltage of 27 V with a tolerance of ±5%, tested at a current of 5 mA. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum Zener impedance of 80 Ω at the test current and a leakage current not exceeding 0.1 µA at a reverse voltage of 20 V.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Moisture sensitivity level 1 compliance per J-STD-020
- Halogen-free construction according to IEC 61249-2-21
- Suitable for automated assembly processes
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix (e.g., RFG) against the manufacturer's datasheet to confirm halogen-free status and packaging details. Ensure the component meets RoHS compliance requirements for the intended application. Cross-reference the marking code KDP to validate authenticity upon receipt.
Selection Notes
Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. Confirm that the 27 V nominal voltage and ±5% tolerance align with the circuit design specifications. Verify thermal management capabilities given the 300 mW power dissipation limit.
Part Context
This part belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. All devices in this series share the same SOT-23 mechanical outline and electrical testing conditions, differing primarily in their nominal breakdown voltage and corresponding marking codes.
Replacement Considerations
Direct replacements must match the SOT-23 package, dual common anode configuration, and 27 V nominal voltage. Verify equivalent power dissipation and impedance ratings from alternative manufacturers before substitution.
FAQ
