AZ23C20_R1_00001

Overview

The AZ23C20_R1_00001 is a dual surface mount Zener diode from the AZ23C2V4 series manufactured by Panjit International Inc. It features a common anode configuration within a SOT-23 molded plastic case. The nominal Zener voltage is 20 V with a tolerance range of 19.00 V to 21.00 V. Maximum power dissipation is rated at 300 mW, and the maximum reverse leakage current is 0.1 µA at 15.0 V. Electrical testing is conducted at a test current of 5.0 mA. The device supports an operating junction temperature range from -55 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common anode package for space-efficient circuit design.
• Compliant with EU RoHS 2011/65/EU directives and utilizes halogen-free green molding compound.
• Optimized mechanical dimensions suitable for automatic insertion manufacturing processes.

Applications

• Voltage reference circuits requiring dual stable potential sources.
• Clamping applications for transient voltage suppression in low-power electronics.
• Biasing networks in analog signal processing stages.

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the specific marking code D22 and the ordering suffix R1_00001. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain solderability and electrical performance upon assembly.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required. The 20 V nominal voltage and 300 mW power rating define its operational limits. Verify that the 50 Ω maximum Zener impedance meets the dynamic resistance requirements of the target application circuit.

Part Context

This part belongs to the AZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V. All members share identical physical packaging and thermal characteristics. The series provides a standardized solution for designers needing multiple voltage references in a compact surface-mount footprint without varying case styles.

Replacement Considerations

Direct substitutes must match the SOT-23-3 package, common anode configuration, and 20 V nominal voltage. Verify equivalent power dissipation and leakage current specifications before substitution.
