Overview
The AZ23B5V1HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 5.1 V at a test current of 5 mA, with a maximum reverse leakage current of 2 uA and a Zener impedance of 60 Ohms. The device operates within a temperature range of -55 C to +150 C and dissipates up to 300 mW. Packaged in an SOT-23-3 surface-mount format, it exhibits a voltage temperature coefficient of 1.2 mV/C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Surface-mount SOT-23-3 package suitable for automated assembly
- Wide operating temperature range from -55 C to +150 C
Applications
- Voltage reference circuits requiring dual polarity or common ground connections
- Clamping applications in signal conditioning paths
- Over-voltage protection stages in low-power electronic systems
Procurement Notes
Verify the specific ordering suffix HE3-TP against official MCC documentation to confirm compliance status and packaging details. Ensure that the requested quantity matches available reel or cut tape options provided by authorized distributors. Confirm component authenticity through manufacturer channels prior to procurement.
Selection Notes
Select this component when a dual Zener structure with a common anode is required in a compact SOT-23-3 footprint. Evaluate the 5.1 V nominal voltage and 300 mW power dissipation limits against circuit requirements. Consider the 60 Ohm impedance and 2 uA leakage specifications for precision applications.
Part Context
This part belongs to the AZ23B series of dual Zener diodes from Micro Commercial Components. It shares the SOT-23-3 package form factor with other variants in the family but differs in internal Zener voltage configurations. The series supports various voltage combinations for differential signaling or dual-reference needs.
Replacement Considerations
Cross-reference with other dual common anode Zener diodes in the SOT-23-3 package having similar 5.1 V characteristics. Verify pinout compatibility and electrical parameters such as impedance and leakage current before substitution.
