AZ23C3V3 RFG

Overview

The AZ23C3V3 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 3.3 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and a test current of 5 mA. It operates within a temperature range of -55°C to +150°C TJ. The component is housed in an SOT-23 package (TO-236-3, SC-59) and contains two silicon elements. It complies with RoHS standards and has a moisture sensitivity level of 1.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Wide voltage tolerance of ±5% for precise regulation
• Surface mount SOT-23 packaging suitable for automated assembly

Applications

• Voltage reference circuits requiring dual regulated rails
• Clamping applications in signal processing paths
• Protection stages in portable electronic devices

Procurement Notes

Verify the complete part number including the RFG suffix to ensure correct packaging and material specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for updated environmental declarations such as REACH status. Ensure the supplier provides valid traceability data for quality assurance purposes during the procurement process.

Selection Notes

Select this component when a dual Zener array in a compact SOT-23 footprint is required. The 3.3 V nominal voltage and ±5% tolerance suit applications needing stable reference levels. Consider the 300 mW power rating and operating temperature range for thermal management. Verify that the common anode configuration aligns with the circuit topology requirements.

Part Context

This part belongs to the AZ23C series of small signal Zener diodes from Taiwan Semiconductor. The series offers various voltage options in the same SOT-23 package family. The RFG suffix typically indicates specific reel packaging and lead finish characteristics defined by the manufacturer for surface mount production lines.

Replacement Considerations

Cross-reference with Vishay AZ23C3V3-G3-08 or Panjit AZ23C3V3-AU_R1_000A1 for pin-compatible alternatives. Verify electrical parameters such as Zener impedance and leakage current match the original design requirements before substitution.
