Overview
The AZ23B9V1HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components. It operates within a voltage range of 6.2V to 100V and is housed in a compact SOT-23-3 surface-mount package. The device features a power dissipation rating of 300 mW and supports a maximum operating temperature of +150°C. Designed for high reliability, it offers low leakage current and stable voltage regulation, making it suitable for automotive and industrial applications requiring robust protection against voltage transients.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- High-temperature resilience with operation up to +150°C
- Compact SOT-23-3 surface-mount packaging for automated placement
Applications
- Automotive instrument cluster solutions
- Front and rear LED lighting systems
- Industrial voltage regulation circuits
Procurement Notes
Verify the specific Zener voltage variant required, as the AZ23B series includes multiple part numbers distinguished by voltage ratings (e.g., AZ23B9V1 vs AZ23B10). Confirm availability status through authorized distributors, as supply may be restricted in certain regions. Ensure the ordering suffix matches the exact electrical specification needed for the target application.
Selection Notes
Select this component when a dual Zener structure in a small footprint is required. Verify that the specific breakdown voltage of the '9V1' variant aligns with the circuit's clamping requirements. Consider the 300 mW power dissipation limit and thermal management needs for the intended operating environment.
Part Context
This part belongs to the AZ23B series of Zener diodes from Micro Commercial Components. The series is characterized by its wide voltage range and automotive-grade reliability. The 'HE3' suffix typically indicates Halogen-free and RoHS-compliant construction, while 'TP' denotes tape-and-reel packaging for high-volume manufacturing.
Replacement Considerations
Direct substitutes must match the dual common anode configuration, SOT-23-3 package, and similar electrical characteristics. Check datasheets for equivalent parts from other manufacturers offering comparable voltage tolerance and power dissipation in the same form factor.
