Overview
The Diotec Semiconductor 2BZX84C27 is a planar Zener diode housed in an SOT-23 (TO-236) surface-mount package. It features a common anode configuration with a nominal Zener voltage range of 25.1 V to 28.9 V at a test current of 5 mA. The device supports a total 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 80 Ω, a reverse leakage current of 1 µA at 18.9 V, and a maximum Zener current of 10 mA.
Feature Summary
- Sharp Zener voltage breakdown for stable regulation
- Low leakage current performance
- Common anode dual-diode configuration
Applications
- Voltage stabilization circuits
- General-purpose voltage regulators
Procurement Notes
Verify the specific suffix against official documentation to confirm compliance status. Standard commercial grades lack automotive qualification, while suffixes like -Q or -AQ indicate AEC-Q101 alignment. Confirm RoHS and REACH adherence through manufacturer datasheets before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring a common anode Zener reference in compact designs. Ensure the operating current remains below the 10 mA maximum limit to maintain thermal stability. Verify that the required voltage tolerance aligns with the standard E24 grading provided in the electrical characteristics table.
Part Context
This part belongs to the BZX84Cxx and 2BZX84Cxx series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V. The '2' prefix specifically denotes the common anode variant, distinguishing it from the single diode BZX84Cxx counterparts within the same physical footprint.
Replacement Considerations
Direct substitutes include other manufacturers' SOT-23 common anode Zener diodes with matching 27 V nominal ratings and 300 mW power dissipation. Verify pinout compatibility and dynamic resistance values to ensure circuit performance equivalence.
