DZ23C5V1_R1_00001

Overview

The DZ23C5V1_R1_00001 is a dual surface mount Zener diode from the Panjit DZ23C2V4 series, housed in an SOT-23 package. It features a common cathode configuration with two independent Zener elements. The nominal Zener voltage is 5.1 V, with a tolerance range of 4.85 V to 5.36 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and thermal resistance (junction to ambient) is 420 °C/W. Electrical characteristics include a maximum Zener impedance of 60 Ω at IZT and 480 Ω at IZK, alongside a maximum reverse leakage current of 0.1 μA at VR = 0.8 V. Operating temperatures span from -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 surface mount package
• Common cathode configuration for efficient circuit layout and automatic insertion
• Compliant with EU RoHS 2.0 standards using green molding compound

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in signal processing paths
• Biasing networks in low-power electronic modules

Procurement Notes

Verify the specific packing code suffix against official documentation before ordering. The R1 suffix indicates Tape and Reel packaging on a 7-inch reel. Confirm that the component version meets required environmental compliance standards such as RoHS 2.0 or lead-free specifications. Ensure the lot number is recorded for traceability purposes during quality assurance reviews.

Selection Notes

Select this component when a dual Zener solution in a small outline package is required. The 5.1 V nominal voltage suits standard logic level referencing. Verify that the 300 mW power rating accommodates the expected dissipation in the target application. Check that the operating temperature range aligns with the environmental conditions of the final assembly.

Part Context

This part belongs to the DZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V. All members share the same SOT-23 mechanical footprint and common cathode topology. The series provides standardized electrical parameters across various voltage levels, allowing designers to maintain consistent board layouts while adjusting voltage references.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, 5.1 V nominal voltage, and common cathode configuration. Verify that substitute components meet the 300 mW power dissipation and 60 Ω impedance requirements. Cross-reference marking codes if visual identification is necessary for production line verification.
