Overview
The Diotec Semiconductor 2BZX84C47 is a surface-mount planar Zener diode housed in an SOT-23 package. It features a common anode configuration with a nominal Zener voltage range of 44 V to 50 V at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. Electrical characteristics include a dynamic resistance of less than 170 Ohms at 1 kHz and a reverse leakage current of 5 µA at the rated reverse voltage. The component complies with RoHS standards and utilizes a UL 94V-0 case material.
Feature Summary
- Sharp Zener voltage breakdown characteristic
- Low leakage current specification
- Common anode dual-diode configuration
Applications
- Voltage stabilization circuits
- Linear voltage regulators
Procurement Notes
Verify the specific suffix designation when ordering, as it determines the quality grade. The standard commercial grade lacks automotive qualification, while suffixes such as -Q or -AQ indicate AEC-Q101 compliance or qualification respectively. Confirm that the required reliability level matches the selected grade for the intended application environment before finalizing procurement.
Selection Notes
Select this component for applications requiring a common anode Zener reference in a compact SOT-23 footprint. Ensure the circuit design accommodates the 300 mW power dissipation limit and the specified thermal resistance. Verify that the 44 V to 50 V voltage range aligns with the target regulation requirements and that the operating temperature falls within the -50°C to +150°C junction range.
Part Context
This part belongs to the BZX84Cxx and 2BZX84Cxx series from Diotec Semiconductor, which covers Zener voltages from 2.4 V to 47 V. The '2' prefix denotes the common anode variant, distinguishing it from the single diode BZX84Cxx counterparts. These components are designed for general-purpose surface-mount assembly in standard commercial and industrial electronic equipment.
Replacement Considerations
Direct replacements must match the SOT-23 package, common anode topology, and the 44 V to 50 V Zener voltage range. Verify that substitute components meet or exceed the 300 mW power dissipation rating and the specified dynamic resistance limits to ensure equivalent circuit performance.
