DZ23C22_R1_00001

Overview

The DZ23C22_R1_00001 is a dual surface mount Zener diode from the DZ23C2V4 series manufactured by Panjit International Inc. It features a common cathode configuration within an SOT-23 molded plastic case. The nominal Zener voltage is 22 V with a tolerance range of 20.90 V to 23.10 V at a test current of 5 mA. Maximum power dissipation is rated at 300 mW, and thermal resistance from junction to ambient air is 420 °C/W. Electrical characteristics include a maximum Zener impedance of 55 Ω at 5 mA and a maximum reverse leakage current of 0.1 μA at 17 V. The device operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode package for space-efficient circuit design.
• Compliant with EU RoHS 2.0 directives and utilizes green molding compound per IEC 61249 standards.
• Designed for automatic insertion processes suitable for high-volume manufacturing.

Applications

• Voltage reference circuits requiring dual stable potentials.
• Clipping and clamping applications in signal processing.
• Protection stages in portable electronic devices.

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm lot numbers match tracking requirements as Panjit uses lot-based identification. Ensure packaging specifications align with automated assembly equipment capabilities. Review datasheet revisions for any updates to electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array in a common cathode topology is required within an SOT-23 footprint. Verify that the 300 mW power rating and 22 V breakdown voltage meet circuit constraints. Consider the 55 Ω impedance value for dynamic regulation needs. Ensure operating temperatures remain within the specified -65 °C to +150 °C range for reliability.

Part Context

This part belongs to the DZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V. All members share identical mechanical dimensions and thermal characteristics. The R1 suffix indicates Tape and Reel packing on a 7-inch reel compliant with RoHS standards. Other variants in the series offer different voltage ratings while maintaining the same package and configuration.

Replacement Considerations

Direct replacements must maintain the SOT-23-3 package, common cathode configuration, and 22 V nominal voltage. Verify that substitute components meet the 300 mW power dissipation and 55 Ω impedance limits. Cross-reference marking codes if visual inspection is required for assembly verification.
