Overview
The AZ23C20-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 20 V with a maximum reverse leakage current of 100 nA at 17 V. The device operates within a power dissipation limit of 300 mW and maintains a Zener impedance of 55 Ohms when tested at 5 mA. Designed for surface mount applications, it utilizes the SOT-23-3 package. The component supports an operating temperature range from -55°C to +150°C and exhibits a voltage temperature coefficient of 18 mV/°C.
Feature Summary
- Dual common anode configuration integrates two Zener diodes into a single compact package.
- Surface mount design in SOT-23-3 housing facilitates automated assembly and space-constrained layouts.
- High thermal stability ensures reliable operation across extended industrial temperature ranges.
Applications
- Voltage reference circuits requiring stable dual supply rails
- Transient voltage suppression in signal conditioning paths
- Over-voltage protection for low-power digital logic inputs
Procurement Notes
Verify the specific suffix against official MCC documentation to confirm exact electrical tolerances and compliance status. Distributor listings may vary in descriptive accuracy; always cross-reference the manufacturer datasheet for definitive specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution is required in a minimal footprint. Ensure the circuit design accommodates the 300 mW power dissipation limit and verify that the 20 V breakdown voltage aligns with the target protection or reference levels.
Part Context
This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 form factor with other variants in the family but differs in nominal voltage ratings and specific electrical characteristics defined by the numeric suffix.
