Overview
The AZ23C51 RFG is a Zener diode manufactured by Taiwan Semiconductor Corporation, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 23V at a test current of 5mA, with a maximum Zener impedance of 40 ohms to ensure stable performance under varying load conditions. The device is housed in the DO-214AC (SMA) surface-mount package, facilitating automated assembly and compact circuit board layouts. Key electrical specifications include a maximum DC forward current of 1A and a peak pulse power dissipation rating of 500W, allowing it to handle transient energy surges effectively while maintaining reliable operation within its specified temperature range.
Feature Summary
- Provides precise voltage regulation through stable Zener breakdown characteristics
- Engineered for high surge tolerance with significant peak pulse power handling capability
- Optimized for surface-mount technology integration using standard SMA packaging
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in power supply inputs
- Clamping applications for transient voltage suppression
Procurement Notes
Verify the component authenticity by checking the marking code on the DO-214AC package against official Taiwan Semiconductor datasheets. Ensure the suffix matches the specified reel or tape configuration if purchasing in bulk quantities. Confirm that the supplier provides traceability documentation to guarantee the part meets the original manufacturer's quality standards and specifications.
Selection Notes
Select this component when a 23V regulation point is required in space-constrained designs. The SMA package offers a balance between thermal performance and footprint size. Consider the 500W peak pulse rating for environments with frequent transients. Ensure the operating current remains within the 5mA test condition limits for accurate voltage regulation during steady-state operation.
Part Context
This part belongs to the standard Zener diode family from Taiwan Semiconductor, widely used in general-purpose electronics. The AZ series typically denotes specific voltage ratings within their discrete semiconductor portfolio. These components are essential for protecting sensitive downstream circuitry from voltage spikes and providing stable reference voltages in analog and digital systems.
Replacement Considerations
Direct replacements must match the 23V Zener voltage, DO-214AC package, and similar power ratings. Verify compatibility with alternative manufacturers' SMA-packaged Zener diodes having comparable impedance and current specifications before substitution.
