Overview
The AZ23C47 is a dual SMD Zener diode from the AZ23C series, manufactured by Taiwan Semiconductor Corporation. It operates within a Zener voltage range of 44V to 50V, with a nominal value of 47V at a test current (Izt) of 5mA. The device features a maximum Zener impedance (Zzt) of 100Ω and a maximum leakage current (Ir) of 1µA at 35V. It is housed in an SOT-23 package and supports a maximum power dissipation of 300mW. The junction temperature range extends from -55°C to +150°C, with a thermal resistance (RθJA) of 420°C/W.
Feature Summary
- Dual configuration designed for automated assembly processes
- Moisture sensitivity rated at Level 1 per J-STD-020
- RoHS compliant and halogen-free construction
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 packing format utilizes a 7-inch reel containing 3000 units per reel. Confirm halogen-free status if required by project specifications, as indicated by the 'G' suffix in ordering codes. Ensure compatibility with SOT-23 footprint requirements during component sourcing.
Selection Notes
Select this component when a precise 47V reference is needed in a compact surface-mount form factor. The low leakage current and defined impedance make it suitable for precision regulation tasks. Verify that the operating environment stays within the specified thermal limits and that the PCB layout accommodates the SOT-23 package dimensions and suggested pad layout provided in the mechanical data section.
Part Context
This part belongs to the AZ23C series, which offers a wide selection of Zener voltages ranging from 2.7V to 51V. All devices in this family share the same SOT-23 package and general electrical characteristics, differing primarily in their nominal Zener voltage and associated marking codes. The series is designed for general-purpose voltage regulation and protection applications.
Replacement Considerations
Direct substitutes must match the SOT-23 package, 300mW power rating, and 47V nominal Zener voltage. Verify that alternative components meet the same leakage current and impedance specifications. Ensure the replacement part is compatible with the existing PCB footprint and thermal management requirements.
