Overview
The AZ23C33 RFG is a dual Zener diode array manufactured by Taiwan Semiconductor Corporation, housed in an SOT-23 surface-mount package. It features a common anode configuration with two silicon elements sharing a single terminal. The nominal Zener voltage is 33 V with a tolerance of ±5%. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance is 250 Ohms. The device operates within a junction temperature range of -55°C to 150°C, exhibits a reverse leakage current of 100 nA at 24.75 V, and complies with RoHS standards.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs
- Common anode configuration simplifies circuit layout and reduces component count
- High thermal stability supporting operation up to 150°C junction temperature
- Lead-free construction compliant with environmental directives
Applications
- Voltage reference circuits requiring stable dual supply rails
- Transient voltage suppression in low-power signal lines
- Clamping applications for protecting sensitive input stages
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with standard reflow soldering profiles and moisture sensitivity level requirements during assembly planning.
Selection Notes
Select this component when a dual Zener solution with common anode topology is required in a small outline package. Confirm that the 300 mW power rating and 33 V breakdown voltage align with the target circuit's operational limits and thermal management capabilities.
Part Context
This part belongs to the AZ23C series of dual Zener arrays from Taiwan Semiconductor. The series offers various voltage options within the same footprint, allowing designers to maintain consistent board layouts while adjusting voltage specifications across different product variants.
Replacement Considerations
Cross-reference with Vishay AZ23C33-GS08 or Micro Commercial Components AZ23C33HE3-TP for pin-compatible alternatives. Verify that substitute parts match the 300 mW power rating and ±5% voltage tolerance before implementation.
