Diodes Incorporated BZX84B6V2-7-F

Overview

BZX84B6V2-7-F from Diodes Incorporated is a precision 6.2 V ±2% tolerance Zener diode in SOT23 package, rated for 350 mW power dissipation at ambient temperature, with 10 Ω typical Zener impedance at 5 mA test current and 0.4 mV/°C temperature coefficient - used for voltage regulation and reference in low-power analog circuits.

For engineers reviewing the BZX84B6V2-7-F datasheet, BZX84B6V2-7-F pinout, BZX84B6V2-7-F application, or BZX84B6V2-7-F equivalent, key selection criteria include tight voltage tolerance (±2%), low dynamic impedance (10 Ω), AEC-Q101 qualification, RoHS-compliant lead-free construction, and SOT23 surface-mount compatibility with automated assembly.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable 6.2 V reference voltage across load variations, with specified test current of 5.0 mA and knee current of 1.0 mA. Its thermal resistance is 357 °C/W when terminals are held at ambient temperature, enabling reliable operation up to +150 °C junction temperature.

The device exhibits a positive temperature coefficient of +0.4 mV/°C near 6.2 V, minimizing drift in mid-voltage references. It delivers <3.0 µA reverse leakage at 4.0 V and supports fast transient response due to low total capacitance (~30 pF at 1 V reverse bias), making it suitable for noise-sensitive analog supply rails.

FAQ

What is the maximum reverse voltage this Zener can withstand before breakdown?

The BZX84B6V2-7-F has a nominal Zener voltage of 6.2 V with a guaranteed range of 6.08 V to 6.32 V at 5 mA test current. Breakdown occurs within this band; it is not rated for sustained reverse voltage above 6.32 V without exceeding power limits or risking parametric shift.

Is this part suitable for use in automotive applications?

Yes - BZX84B6V2-7-F is explicitly qualified to AEC-Q101 standards, including stress tests for temperature cycling, humidity, and mechanical shock. Its SOT23 package and RoHS-compliant construction meet automotive electronics requirements for body control, infotainment, and sensor interface modules.

How does the temperature coefficient affect its performance in wide-temperature environments?

With a +0.4 mV/°C temperature coefficient, the Zener voltage increases by approximately 40 mV over a 100°C span (e.g., −40°C to +60°C). This low drift supports stable reference operation in industrial and automotive applications where compensation is minimal or unnecessary.

Can this Zener be used in place of a 6.8 V or 5.6 V variant in an existing design?

No - substituting BZX84B6V2-7-F for 5.6 V or 6.8 V Zeners alters the regulated voltage point by >10%, potentially causing overvoltage or undervoltage in downstream circuitry. Each variant is optimized for its specific nominal voltage; cross-voltage substitution requires full electrical validation.
