Product details
Overview
PDZ6.8BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at nominal 6.8 V with ±2 % tolerance (B-series), 60 Ω max differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ6.8BGW datasheet, PDZ6.8BGW pinout, PDZ6.8BGW application, or PDZ6.8BGW equivalent, this device supports stable low-power voltage clamping, ESD protection interface biasing, and analog reference generation where tight Zener voltage accuracy and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 6.8 V at IZ = 5 mA, exhibiting a temperature coefficient of +3.4 mV/K and typical reverse current ≤0.5 μA at VR = 5.5 V. Its differential resistance remains ≤60 Ω under rated test conditions.
Thermal performance is defined by Rth(j-a) = 340 K/W (free air) and Rth(j-sp) = 200 K/W (solder point), enabling reliable operation up to Tj = 150 °C. The device sustains non-repetitive peak reverse power dissipation of 40 W for 100 μs pulses.

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 |
|---|---|---|---|
| BZX84-C6V8 | Same 6.8 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot | Larger package footprint; higher leakage (≤5 μA at 5.5 V); no AEC-Q101 qualification | Select when automotive qualification is unnecessary and board space allows SOT23 mounting |
| MMSZ4688 | 6.8 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, 100 Ω rdif | Higher power rating but looser tolerance and higher dynamic impedance reduce regulation accuracy | Prefer for higher-power clamping where ±2 % accuracy is not critical and thermal margin exceeds 365 mW |
Compared with BZX84-C6V8 and MMSZ4688, PDZ6.8BGW delivers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (60 Ω vs. ≥100 Ω), and automotive-grade reliability-making it optimal for safety-critical and precision analog designs where long-term stability matters.

FAQ
What is the maximum continuous reverse current the PDZ6.8BGW can sustain at 25 °C ambient?
The PDZ6.8BGW sustains up to 53 mA continuous reverse current at 25 °C ambient, calculated from its 365 mW total power dissipation rating and nominal 6.8 V Zener voltage (IZ = Ptot/VZ). Derating applies above 25 °C per the thermal resistance curve.
How does the +3.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, the +3.4 mV/K coefficient causes a +0.34 V shift over a 100 K rise (e.g., −40 °C to +60 °C), contributing ~5 % of nominal voltage. Combined with ±2 % initial tolerance, total worst-case deviation is ±7 % across that range-critical for high-accuracy references.
Can PDZ6.8BGW be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, minor VZ mismatches cause current hogging. Parallel operation risks thermal runaway; use a single higher-rated device or external current-sharing resistors if absolutely required.
Is the SOD123 footprint compatible with reflow soldering per JEDEC standards?
Yes-the PDZ6.8BGW SOD123 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. Recommended footprint matches Nexperia's Figure 9: 2.36 mm × 1.11 mm copper pad with 0.81 mm solder mask opening and 0.91 mm stencil aperture.
