Overview
The Diotec Semiconductor 2BZX84C33 is a common anode SMD planar Zener diode housed in a SOT-23 (TO-236) package. It provides a nominal Zener voltage of 33 V with a tolerance range of 31 V to 35 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. Key electrical characteristics include a dynamic resistance of less than 80 Ω, a reverse leakage current of 0.05 µA at 23.1 V, and a temperature coefficient between +7% and +10%.
Feature Summary
- Common Anode Configuration: Features two integrated Zener diodes sharing a single anode terminal for efficient circuit design.
- Sharp Breakdown Characteristics: Utilizes planar die construction to ensure precise voltage regulation and low leakage currents.
- Automotive Compliance Options: Available in AEC-Q101 compliant (-Q) and qualified (-AQ) grades for automotive applications.
Applications
- Voltage stabilization and regulators
- Dual-channel reference voltage generation
- Over-voltage protection circuits
Procurement Notes
Verify the specific suffix when ordering. The base model represents industrial grade. Append -C for commercial grade, -Q for AEC-Q101 compliance, or -AQ for full qualification. Confirm tape and reel quantities match production requirements before finalizing orders.
Selection Notes
Select this component for dual-reference designs requiring a common ground connection. Ensure the total current through both channels does not exceed the thermal limits defined by the 300 mW power dissipation rating. Verify that the operating ambient temperature remains within the specified -50°C to +150°C range.
Part Context
This part belongs to the BZX84C series of surface-mount Zener diodes manufactured by Diotec Semiconductor. The '2' prefix specifically denotes the common anode configuration, distinguishing it from the standard single-diode BZX84C variants while maintaining identical physical dimensions and basic electrical parameters.
Replacement Considerations
Direct functional substitutes include other common anode Zener diodes in the SOT-23 package with matching 33V ratings. Verify pinout compatibility and thermal resistance values when replacing with components from different manufacturers.
FAQ
What is the difference between the -Q and -AQ suffixes?
The -Q suffix indicates the device is AEC-Q101 compliant, while the -AQ suffix signifies that the device has been fully qualified according to AEC-Q101 automotive standards.
How is the maximum current distributed in the common anode configuration?
The maximum Zener current (IZmax) applies per device. For the 2BZX84C33, the maximum current at Pin 3 is limited to 9 mA under standard mounting conditions.
What is the typical junction capacitance for this voltage rating?
While exact values vary with reverse voltage, the datasheet provides typical junction capacitance curves showing values generally below 10 pF at 1 MHz for voltages around 33 V.
