Overview
The DZ23C3V9_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 3.9 V, with a tolerance range of 3.71 V to 4.10 V. Maximum power dissipation is rated at 300 mW, and the maximum reverse leakage current is 3.0 µA at 1.0 V. Electrical testing is conducted at a test current of 5.0 mA, yielding a maximum Zener impedance of 90 Ω.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
- Common cathode configuration simplifies biasing requirements by sharing a single ground reference.
Applications
- Voltage regulation in low-power electronic circuits
- Clipping and clamping applications for signal protection
- Reference voltage generation in analog systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The suffix indicates tape and reel packing on a 7-inch plastic reel compliant with RoHS standards. Confirm that the component lot number is available for tracking purposes when placing orders or addressing quality inquiries.
Selection Notes
Select this component for applications requiring precise dual voltage references within a small footprint. Ensure the operating junction temperature remains within the -65°C to +150°C range. Verify that the thermal resistance of 420°C/W is manageable for the intended PCB land area and power dissipation conditions.
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 electrical characteristics structure, differing only in their specific breakdown voltage ratings and corresponding marking codes.
Replacement Considerations
Other parts within the DZ23C2V4 series may serve as functional substitutes if different voltage levels are required. Cross-referencing with other manufacturers' dual Zener arrays in SOT-23 packages requires careful verification of pinout compatibility and electrical parameter tolerances.
