2BZX84B3V6

Overview

The Diotec Semiconductor 2BZX84B3V6 is a planar Zener diode housed in an SOT-23 (TO-236) surface-mount package. It provides a nominal Zener voltage of 3.6 V with a tight tolerance of ±2%, ranging from 3.53 V to 3.67 V at a test current of 5 mA. The device dissipates up to 300 mW and operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a dynamic resistance below 90 Ohms, a reverse leakage current of 5 µA at 1 V, and a negative temperature coefficient between -8% and -5%. It features a common anode configuration.

Feature Summary

• Features sharp Zener voltage breakdown for precise regulation
• Offers low leakage current for efficient standby operation
• Complies with RoHS directives without exemptions

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix when purchasing. Standard versions are commercial grade. Suffixes -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm these designations match project requirements before procurement.

Selection Notes

Select this component for applications requiring a 3.6 V reference with high precision. Ensure the circuit can handle the maximum Zener current of 82 mA. Verify that the thermal resistance of 420 K/W aligns with the ambient temperature conditions of the final assembly.

Part Context

This part belongs to the BZX84B 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 '2B' prefix specifically identifies the common anode dual-diode variant within the SOT-23 package family.

Replacement Considerations

Cross-referencing requires matching the 3.6 V nominal voltage, ±2% tolerance, SOT-23 package, and 300 mW power rating. Verify that substitute components support the common anode configuration if replacing the 2BZX84B3V6 specifically.
