Product details
Overview
PDZ6.8BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at nominal 6.8 V with ±2 % tolerance (B-series), 60 Ω max differential resistance at IZ = 5 mA, 0.5 μA max reverse current at VR = 5.5 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ6.8BGWX datasheet, PDZ6.8BGWX pinout, PDZ6.8BGWX application, or PDZ6.8BGWX equivalent, this device serves as a stable, low-capacitance (215 pF @ 1 MHz, VR = 0 V) voltage clamp in power supply feedback loops, overvoltage protection circuits, and analog reference networks where thermal stability (SZ = +3.4 mV/K at IZ = 5 mA) and surface-mount compatibility are critical.
Technical Context
This Zener operates in reverse breakdown mode with a specified working voltage of 6.65 V to 6.93 V at IZ = 5 mA, delivering tight regulation via low dynamic impedance and controlled temperature coefficient. Its non-repetitive peak reverse power dissipation reaches 40 W under 100 μs pulses, enabling transient suppression capability beyond steady-state limits.
The device exhibits forward voltage ≤0.9 V at IF = 10 mA and ≤1.1 V at IF = 100 mA, supporting bidirectional clamping or dual-role use in some protection topologies. Thermal resistance from junction to solder point is 50 K/W, confirming effective heat transfer through the cathode pad in standard FR4 PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 6.8 V - precise DC voltage reference point for regulation or clamping |
| VZ tolerance | ±2 % - ensures predictable trip or reference voltage across production lots |
| rdif max | 60 Ω at IZ = 5 mA - low dynamic impedance maintains regulation accuracy under load variation |
| IR max | 0.5 μA at VR = 5.5 V - minimal leakage preserves efficiency in high-impedance bias networks |
| SZ | +3.4 mV/K at IZ = 5 mA - positive tempco enables compensation in mixed-technology circuits |
| Cd | 215 pF at f = 1 MHz, VR = 0 V - low capacitance avoids signal distortion in RF or fast-switching paths |
| Ptot | 365 mW at Tamb ≤ 25 °C - defines continuous power handling on standard FR4 PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8 | Same 6.8 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot, 40 Ω rdif | Higher leakage (5 μA @ 5.5 V), no AEC-Q101 qualification | Select for cost-sensitive consumer designs where automotive qualification is unnecessary |
| MMSZ4687T1G | 6.8 V nominal, ±5 %, SOD123, 500 mW Ptot, 100 Ω rdif, no AEC-Q101 | Higher power rating but looser tolerance and higher dynamic impedance | Prefer when higher continuous dissipation is required and tighter regulation is secondary |
Compared with BZX84-C6V8 and MMSZ4687T1G, PDZ6.8BGWX delivers superior voltage accuracy (±2 % vs. ±5 %), automotive qualification, and lower leakage-making it optimal for safety-critical or high-precision regulation where long-term stability and environmental robustness are mandatory.

FAQ
What is the maximum reverse voltage (VR) before significant leakage occurs in PDZ6.8BGWX?
At VR = 5.5 V, reverse current is guaranteed ≤0.5 μA. This threshold reflects the onset of measurable conduction just below nominal Zener voltage, ensuring minimal loading on upstream circuitry in standby or pre-breakdown states.
How does the +3.4 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over that range, VZ shifts approximately +300 mV - from ~6.65 V to ~6.95 V. This predictable positive drift allows designers to compensate elsewhere in the system, such as in op-amp offset or ADC reference scaling, without introducing instability.
Can PDZ6.8BGWX be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative resistance characteristics and mismatched VZ tolerances cause current hogging. Parallel operation is not recommended; instead, use a single higher-rated device or external series resistors with forced current sharing if absolutely necessary.
Is the SOD123 package compatible with standard reflow profiles per IPC-J-STD-020?
Yes - Nexperia specifies reflow soldering only, with peak temperature ≤260 °C and time above liquidus ≤60 seconds. The SOD123 outline matches IPC-7351B SOIC-2 footprint standards, supporting automated placement and RoHS-compliant thermal cycling.
