Product details
Overview
D3Z6V8BF-7 from Diodes Incorporated is a precision 6.8 V Zener diode in SOD323F package, rated for 400 mW power dissipation on FR-4 PCB, with ±3.5% zener voltage tolerance (6.65–6.93 V at 5 mA), 40 Ω dynamic impedance at 5 mA, and −3.4 mV/°C temperature coefficient. It serves as a stable voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the D3Z6V8BF-7 datasheet, D3Z6V8BF-7 pinout, D3Z6V8BF-7 application, or D3Z6V8BF-7 equivalent, key selection criteria include zener voltage accuracy, thermal stability in compact layouts, low leakage (<0.5 μA at 5.44 V), and compatibility with automated SMT assembly on space-constrained PCBs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a precise DC reference voltage under varying load and temperature conditions. Its tight 6.65–6.93 V range at 5 mA test current and low 40 Ω zener impedance ensure minimal voltage deviation across operating current changes.
The −3.4 mV/°C temperature coefficient indicates predictable, linear drift with ambient temperature, enabling accurate compensation in voltage-regulated sensor interfaces. Its SOD323F package supports high-density placement while maintaining thermal resistance of 312.5 °C/W on standard FR-4 boards.
Key Specifications

| Power Dissipation (PD) | 400 mW on FR-4 PCB - supports continuous operation up to 60°C ambient without derating |
| Temperature Coefficient (TC) | −3.4 mV/°C - enables predictable voltage drift correction in temperature-sensitive designs |
| Reverse Leakage (IR) | 0.5 μA max at 5.44 V - guarantees minimal error current in high-impedance reference nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V8,115 (Nexperia) | Same 6.8 V nominal, but ±5% tolerance (6.46–7.14 V); 80 Ω ZZT; SOD323 package | Higher voltage uncertainty reduces accuracy in 12-bit ADC references | Select when cost priority outweighs ±0.2 V regulation precision |
| MMSZ4687T1G (onsemi) | 6.8 V nominal, ±5% tolerance; 30 Ω ZZT; SOD123 package (larger footprint) | Requires 30% more board area; higher thermal resistance (350 °C/W) | Choose only if legacy SOD123 layout reuse is mandatory |
Compared with BZX384-B6V8 and MMSZ4687T1G, D3Z6V8BF-7 delivers tighter voltage control, lower impedance, and superior thermal performance in the smallest standardized footprint-critical for miniaturized industrial and automotive modules.

FAQ
What is the maximum reverse voltage this Zener can sustain before breakdown?
The D3Z6V8BF-7 has a specified zener voltage range of 6.65–6.93 V at 5 mA test current. Breakdown begins within this range; it is not rated for sustained operation above 6.93 V. Exceeding 7.0 V risks irreversible degradation due to thermal runaway, especially beyond 85°C ambient.
Can this device be used in forward-bias mode like a standard diode?
Yes-it exhibits 0.9 V forward voltage at 10 mA, matching typical silicon diode behavior. However, its primary design intent and characterization are for reverse-bias zener operation; forward conduction is incidental and not optimized for rectification or switching duty cycles.
Is the SOD323F package compatible with standard reflow profiles for lead-free soldering?
Yes-the matte tin annealed terminals meet MIL-STD-202 Method 208 solderability requirements, and the device is qualified for JEDEC J-STD-020 Level 1 moisture sensitivity, supporting peak reflow temperatures up to 260°C without preconditioning.
Does this part meet AEC-Q200 stress testing requirements for automotive use?
No-while manufactured in IATF 16949-certified facilities and suitable for automotive BCM applications, D3Z6V8BF-7 is not AEC-Q200-qualified. For certified automotive-grade equivalents, contact Diodes Incorporated directly for PPAP-capable variants such as the AZ series.
