Overview
The PZD22B2V4C is a silicon Zener diode from the PZD22B series manufactured by Panjit International Inc. It features a nominal Zener voltage of 2.4 V with a tolerance range of 2.28 V to 2.52 V at a test current of 5 mA. The device operates within a power dissipation limit of 200 mW and utilizes an SOT-323 surface-mount package. Electrical characteristics include a maximum reverse leakage current of 50 µA at 1 V, a typical Zener impedance of 100 Ω at 5 mA, and a maximum impedance of 600 Ω at 5 mA. Thermal resistance from junction to ambient is typically 540 °C/W, supporting an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Planar die construction designed for automated assembly processes
- Lead-free composition compliant with EU RoHS 2.0 directives
- Green molding compound formulation adhering to IEC 61249 standards
Applications
- Voltage regulation in low-power electronic circuits
- Overvoltage protection for sensitive semiconductor components
- Reference voltage generation in signal processing applications
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's datasheet revision date and part number against official Panjit documentation. Confirm that the received units match the specified SOT-323 package dimensions and marking code AFH. Ensure compliance with environmental standards such as RoHS 2.0 and IEC 61249 during the sourcing process.
Selection Notes
Select this component when a precise 2.4 V reference or clamp is required in space-constrained designs utilizing the SOT-323 footprint. Consider the 200 mW power dissipation limit and thermal resistance when designing heat management strategies. Verify that the 50 µA maximum reverse leakage current meets the specific requirements of the target circuit application.
Part Context
This component belongs to the PZD22B2V4C ~ PZD22B75C series, which offers a wide range of Zener voltages from 2.4 V to 75 V. All devices in this series share identical mechanical packaging, thermal characteristics, and manufacturing features, differing primarily in their electrical breakdown parameters and marking codes.
Replacement Considerations
Direct substitutes must maintain the 2.4 V nominal voltage, SOT-323 package, and 200 mW power rating. Verify compatibility regarding Zener impedance and leakage current specifications before implementation.
