AZ23C36 RFG

Overview

The AZ23C36 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features two independent Zener diodes sharing a common anode terminal within a single surface-mount package. The nominal Zener voltage is 36 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and operates over a temperature range from -65 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 100 nA at 27 V and a Zener impedance of 90 Ohms at a test current of 5 mA. The component is housed in an SOT-23-3 package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• High thermal stability with extended operating temperature range
• Low leakage current characteristics for precision applications

Applications

• Voltage reference circuits requiring dual rails
• Clamping and protection in signal conditioning paths
• Over-voltage protection in automotive electronics

Procurement Notes

Verify the manufacturer designation as Taiwan Semiconductor Corporation against the specific suffix RFG. Confirm the package type is SOT-23-3 and the power rating is 300 mW. Ensure the Zener voltage is 36 V with ±5% tolerance. Check for AEC-Q101 qualification if automotive use is intended. Validate the reverse leakage current specification of 100 nA.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. The 36 V breakdown voltage suits mid-range reference applications. Consider the 300 mW power dissipation limit for thermal management. Verify compatibility with the target PCB layout for the SOT-23-3 package dimensions.

Part Context

The AZ23C36 series represents a family of dual Zener arrays. The base part number AZ23C36 indicates the 36 V nominal voltage. The RFG suffix typically denotes specific packaging or tape-and-reel configurations from Taiwan Semiconductor. This variant belongs to the broader category of surface-mount Zener diode arrays used in consumer and industrial electronics.

Replacement Considerations

Cross-reference with Diodes Incorporated AZ23C36-7-F or Micro Commercial Components AZ23C36W-TP for pin-compatible alternatives. Verify that substitute parts match the 36 V Zener voltage, 300 mW power rating, and SOT-23-3 package. Ensure equivalent electrical parameters such as leakage current and impedance are met.
