Overview
The AZ23C20-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration housed in an SOT-23 package. The nominal Zener voltage is 20 V with a tolerance range of 18.8 V to 21.2 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 50 Ohms at the test current. The device operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common anode package for space-efficient circuit design.
- High reliability qualification meeting JEDEC standards for robust performance.
- Lead-free construction fully compliant with RoHS directives and halogen-free green manufacturing.
Applications
- Voltage reference circuits requiring dual stable potentials.
- Clamping applications for transient voltage suppression.
- Protection stages in automotive electronic control units.
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to commercial grade specifications and tape & reel packaging. Confirm that the component meets AEC-Q101 ESD ratings if utilized in sensitive environments. Ensure the selected variant aligns with the required thermal resistance and power derating curves for the intended operating conditions.
Selection Notes
Select this component when a compact dual Zener solution is required in an SOT-23 footprint. Consider the 50 Ohm impedance limit and 300 mW power rating against the expected load currents. Verify compatibility with automated insertion processes due to the tape and reel packaging format provided by the manufacturer.
Part Context
This part belongs to the AZ23C series of dual surface mount Zener diodes from Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same common anode architecture and SOT-23 mechanical outline. The 'AZ23C20' designation specifically identifies the 20 V nominal breakdown voltage variant within this family.
Replacement Considerations
Diodes Incorporated lists the DZ23 series as the alternative for customers requiring a common cathode configuration instead of the standard common anode layout found in the AZ23C series.
FAQ
What is the typical temperature coefficient for the AZ23C20?
The typical temperature coefficient for the AZ23C20 is +0.090 %/°C.
Does the AZ23C20-7-F meet automotive standards?
The commercial version (suffix -7-F) is qualified to JEDEC standards. Automotive-grade parts are available with the Q-suffix and are qualified to AEC-Q100/101/104/200.
What is the maximum reverse leakage current?
The maximum reverse leakage current is specified at 0.1 µA (100 nA) when measured at the minimum reverse voltage.
