Product details
Overview
BZX84C6V2Q-7-F from Diodes Incorporated is an AEC-Q101 qualified 6.2 V, 5 mA Zener diode in SOT23 package, rated for 350 mW power dissipation and ±5% zener voltage tolerance at 5 mA test current, with 10 Ω dynamic impedance and 3.0 µA maximum reverse leakage at 4.0 V, used for precision voltage regulation and overvoltage protection in automotive control modules.
For engineers reviewing the BZX84C6V2Q-7-F datasheet, BZX84C6V2Q-7-F pinout, BZX84C6V2Q-7-F application, or BZX84C6V2Q-7-F equivalent, key selection criteria include zener voltage stability across temperature (±0.4 mV/°C), low thermal resistance (357 °C/W), automotive qualification status, and SOT23-compatible footprint for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 6.2 V reference under regulated current conditions. Its planar die construction ensures consistent voltage tolerance and low leakage, while the SOT23 package enables automated surface-mount assembly with lead-free solder compatibility.
The device exhibits a nominal temperature coefficient of +0.4 mV/°C, enabling predictable voltage drift in automotive ambient ranges (−40°C to +125°C). It delivers 10 Ω zener impedance at 5 mA and maintains ≤3.0 µA reverse current at VR = 4.0 V, supporting low-power biasing and sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V range at IZT = 5 mA - defines precise clamping threshold for voltage reference or protection |
| Power Dissipation (PD) | 350 mW at TA = 25°C - sets maximum continuous power handling on standard FR-4 board with ambient-terminal cooling |
| Zener Impedance (ZZT) | 10 Ω at f = 1 kHz, IZT = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤3.0 µA at VR = 4.0 V - guarantees low standby current in battery-powered or always-on circuits |
| Thermal Resistance (RθJA) | 357 °C/W - determines junction temperature rise per watt under ambient-terminal mounting conditions |
| Temperature Coefficient | +0.4 mV/°C - quantifies voltage drift magnitude per degree Celsius for thermal design margining |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.0 V (±5%), 200 mW PD, SOT323 package, 15 Ω ZZT at 20 mA | Lower power rating and higher impedance limit use in high-current regulation or fast transient suppression | Select when board space allows SOT323 and thermal budget restricts to ≤200 mW operation |
| BZX84-C6V2,115 | Same 6.2 V specification but non-automotive grade, SOT23 package, 350 mW PD, RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification and green compound certification; unsuitable for under-hood deployment | Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with BZX84C6V2Q-7-F, MMBZ5234BS-7-F trades lower power and higher impedance for smaller footprint, while BZX84-C6V2,115 offers identical electrical specs without automotive qualification-making the Q-grade essential for vehicular systems requiring long-term reliability under thermal stress.

FAQ
What is the maximum reverse voltage this Zener diode can withstand before breakdown?
The BZX84C6V2Q-7-F has a nominal zener voltage of 6.2 V with a guaranteed range of 5.8 V to 6.6 V at 5 mA test current. Its reverse breakdown is specified only within that range; applying voltage significantly above 6.6 V risks exceeding its 350 mW power limit and causing thermal failure. The device is not rated for sustained operation above its specified VZ range.
Is this part suitable for use in high-temperature under-hood automotive environments?
Yes. The BZX84C6V2Q-7-F is AEC-Q101 qualified and rated for operation from −65°C to +150°C junction temperature. Its +0.4 mV/°C temperature coefficient and 357 °C/W thermal resistance enable predictable performance in under-hood ECUs, provided PCB layout maintains adequate copper area and avoids localized hot spots near the SOT23 package.
How does the "Q" suffix affect packaging and compliance?
The "Q" in BZX84C6V2Q-7-F denotes AEC-Q101 qualification and green (halogen/antimony-free) molding compound. It ships in 3,000-unit tape-and-reel format (7-F designation), with matte tin-plated terminals compliant with MIL-STD-202 solderability standards-distinguishing it from non-Q variants that lack automotive qualification and environmental certifications.
Can this Zener diode replace a 6.8 V variant in an existing circuit?
No. Substituting BZX84C6V2Q-7-F for a 6.8 V Zener (e.g., BZX84C6V8Q-7-F) changes the clamping or reference voltage by 0.6 V, which may cause overvoltage damage to downstream ICs or insufficient regulation margin. The 6.2 V unit's tighter 10 Ω impedance and distinct temperature coefficient also alter dynamic response-replacement requires full circuit validation.
