Overview
The Taiwan Semiconductor AZ23C6V8 is a dual surface-mount Zener diode array housed in an SOT-23 package. It features a common anode configuration with a nominal Zener voltage of 6.8 V and a maximum power dissipation of 300 mW. The device operates within a junction temperature range of -55°C to +150°C. Electrical specifications include a Zener impedance (Zz) of 8 Ω at a test current (Izt) of 5 mA, and a maximum reverse leakage current (Ir) of 3.0 µA at VR = 6.8 V.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
- Common anode configuration simplifies biasing requirements in low-voltage stabilization applications.
- Halogen-free molding compound compliant with IEC 61249-2-21 standards.
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging details. The standard tape-and-reel quantity for this component type is typically 3000 units per 7-inch reel. Confirm RoHS compliance status and halogen-free certification prior to procurement to ensure adherence to environmental regulations.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required for voltage regulation. Ensure the operating voltage aligns with the 6.8 V nominal specification and that the PCB layout accommodates the SOT-23 footprint. Verify thermal management capabilities given the 300 mW power dissipation rating under expected load conditions.
Part Context
This part belongs to the AZ23C series, which covers a wide Zener voltage range from 2.7 V to 51 V. All devices in this family share identical mechanical dimensions and electrical testing parameters, differing primarily in their specific breakdown voltage ratings and corresponding marking codes.
Replacement Considerations
Cross-reference with Vishay Semiconductors AZ23B6V8-G3-08 for similar dual Zener specifications. Verify pinout compatibility and tolerance levels before substitution, as minor differences in impedance or leakage characteristics may exist between manufacturers.
