Overview
The AZ23B3V9HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It is housed in an SOT-23-3 surface-mount package. The device features a nominal Zener voltage of 3.9 V with a tolerance of 5%. It has a power dissipation rating of 300 mW and operates within a temperature range of -55°C to +150°C. The maximum reverse leakage current is specified at 5 mA, with a Zener impedance of 95 Ohms measured at a test current of 5 mA.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Compact SOT-23-3 surface-mount packaging
- Wide operating temperature range suitable for industrial applications
Applications
- Voltage reference circuits
- Signal clipping and protection
- Transient voltage suppression
Procurement Notes
Verify the specific part number against official MCC documentation to ensure compatibility with design requirements. Confirm that the SOT-23-3 package dimensions align with PCB footprint specifications. Check for RoHS compliance status if required by project regulations. Ensure sourcing channels provide authentic components from authorized distributors to avoid counterfeit risks.
Selection Notes
Select this component when a dual Zener solution in a small form factor is required. Consider the 300 mW power dissipation limit for thermal management. Evaluate the 5% voltage tolerance against circuit precision needs. Compare the 95 Ohm impedance value with alternative devices if low-impedance performance is critical for the application.
Part Context
This component belongs to the AZ23B series of dual Zener diodes from Micro Commercial Components. The series offers various voltage options within the same SOT-23-3 package, allowing for standardized inventory management across different voltage reference designs in consumer and industrial electronics.
Replacement Considerations
Cross-reference with other AZ23B series variants for different voltage levels. Verify pinout compatibility with existing layouts before substituting. Check electrical parameters such as impedance and leakage current against original design specifications.
