Product details
Overview
PD3Z284C6V8-7 from Diodes Incorporated is a 0.5W surface-mount Zener diode with nominal zener voltage 6.8V (±5.9% tolerance), 15Ω maximum zener impedance at 5mA, and 2μA maximum reverse leakage at 4.0V. It features PowerDI323 package, AEC-Q101 qualification, and RoHS-compliant "green" molding compound. Used for precision voltage regulation in automotive body control modules.
For engineers reviewing the PD3Z284C6V8-7 datasheet, PD3Z284C6V8-7 pinout, PD3Z284C6V8-7 application, or PD3Z284C6V8-7 equivalent, key selection criteria include zener voltage stability over temperature (±0.4%/°C TC), low capacitance (≈10pF at 1V), thermal resistance (250°C/W), and AEC-Q101 reliability validation for under-hood environments.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across load variations and supply fluctuations. Its planar die construction ensures consistent voltage regulation and low dynamic impedance (15Ω @ 5mA) for noise-sensitive analog circuits.
Designed for high-reliability automotive applications, it meets AEC-Q101 stress testing requirements including temperature cycling, humidity bias, and high-temperature operating life. The PowerDI323 package enables compact PCB layout while maintaining thermal performance up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8V nominal, 6.4–7.2V range at 5mA - defines regulated output voltage tolerance for reference design |
| Power Dissipation | 500mW - supports continuous operation at ambient ≤+85°C with standard pad layout |
| Zener Impedance (ZZT) | 15Ω max @ 5mA - ensures minimal output voltage variation under dynamic load current changes |
| Reverse Leakage (IR) | 2μA max @ 4.0V - guarantees low standby power loss in always-on monitoring circuits |
| Thermal Resistance (RθJA) | 250°C/W - requires minimum copper area per Diodes AP02001 layout to avoid derating above 25°C |
| Temperature Coefficient | +1.2mV/°C - provides predictable voltage drift for temperature-compensated references |
| Capacitance (CT) | ≈10pF @ 1V - enables use in low-frequency feedback paths without phase margin degradation |

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 |
|---|---|---|---|
| D3Z6V8BF-7 | Same 6.8V nominal, lower ZZT (10Ω), higher PD (1W), SOD-323 package | Higher power handling supports wider ambient range but larger footprint | Select for new designs requiring improved thermal margin or extended lifetime beyond legacy PD3Z284C6V8-7 |
| BZX384-C6V8,115 | 6.8V nominal, 90Ω ZZT, 300mW rating, SOD-323, no AEC-Q101 | Lacks automotive qualification; suitable only for commercial-grade consumer electronics | Choose only for non-automotive applications where cost is primary constraint and reliability requirements are relaxed |
Compared with D3Z6V8BF-7 and BZX384-C6V8,115, PD3Z284C6V8-7 offers optimal balance of AEC-Q101 compliance, compact PowerDI323 size, and 15Ω impedance for legacy automotive systems - though Diodes recommends migrating to D3Z6V8BF-7 for new designs.

FAQ
What is the maximum allowable junction temperature for PD3Z284C6V8-7?
The absolute maximum junction temperature is +150°C, verified per AEC-Q101 test conditions. Operation above this limit risks irreversible parametric shift or catastrophic failure. Derating begins at +25°C ambient per Figure 1: at +100°C ambient, maximum power dissipation drops to 300mW using the recommended pad layout from Diodes AP02001.
Is PD3Z284C6V8-7 suitable for use in safety-critical automotive systems?
No - while AEC-Q101 qualified, PD3Z284C6V8-7 is not authorized for life support devices per Diodes' Important Notice. It may be used in non-safety-critical automotive subsystems like interior lighting or HVAC controls, but not in airbag controllers, brake-by-wire, or ADAS power domains without explicit written approval from Diodes' CEO.
How does the PowerDI323 package compare thermally to SOD-323?
PowerDI323 has lower thermal resistance (250°C/W vs. ~350°C/W for typical SOD-323) due to its exposed copper leadframe and optimized internal thermal path. This allows 20% higher continuous power dissipation at the same ambient temperature when using identical PCB copper area, making it preferred for thermally constrained automotive layouts.
Why is PD3Z284C6V8-7 marked as "NOT RECOMMENDED FOR NEW DESIGNS"?
Diodes recommends migrating to the D3ZxxBF series because it offers improved zener impedance (e.g., 10Ω vs. 15Ω), higher power rating (1W vs. 0.5W), tighter voltage tolerance, and enhanced surge robustness - all in the same SOD-323 footprint. PD3Z284C6V8-7 remains fully supported for existing production but lacks roadmap extension beyond current wafer fab capacity.
