Overview
The Diotec Semiconductor 2BZX84C5V1 is a surface-mount planar Zener diode configured as a common anode dual device. It operates within the SOT-23 (TO-236) package and provides a nominal Zener voltage of 5.1 V with a standard tolerance range of 4.8 V to 5.4 V at a test current of 5 mA. The component supports a maximum power dissipation of 300 mW and functions across a junction temperature range of -50°C to +150°C. Electrical characteristics include a dynamic resistance below 60 Ω at 1 kHz and a reverse leakage current of 2 µA at 2 V.
Feature Summary
- Common anode configuration for dual-diode applications
- Sharp Zener voltage breakdown characteristic
- Low leakage current performance
- RoHS compliant without exemptions
Applications
- Voltage stabilization circuits
- Voltage regulator designs
- Reference voltage generation
Procurement Notes
Verify the specific suffix designation when ordering, as it determines the quality grade. The absence of a suffix indicates industrial grade, while the -Q suffix denotes AEC-Q101 compliance. Confirm that the required voltage tolerance aligns with the standard E24 grading provided in the datasheet specifications.
Selection Notes
Select this component for applications requiring a common anode topology in a compact SOT-23 footprint. Ensure the design accounts for the 300 mW power dissipation limit and verify thermal management on the PCB. Check if automotive qualification via the -Q suffix is necessary for the target environment.
Part Context
This part belongs to the BZX84Cxx series of SMD planar Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V. The 2BZX84Cxx variant specifically offers a common anode structure, distinguishing it from the single-diode BZX84Cxx counterparts within the same product family.
Replacement Considerations
Direct substitutes within the same manufacturer line include other 2BZX84Cxx common anode variants such as 2BZX84C4V7 or 2BZX84C5V6, provided the voltage rating matches the circuit requirements.
