Product details
Overview
PD3Z284C9V1-7 from Diodes Incorporated is a 0.5W surface-mount Zener diode with nominal zener voltage 9.1V (min 8.5V, max 9.6V) at 5mA test current, 10Ω maximum zener impedance at IZT, and 0.5μA maximum reverse leakage at 6.0V. It features PowerDI®323 ultra-small package, AEC-Q101 qualification for automotive reliability, and RoHS-compliant "green" molding compound.
For engineers reviewing the PD3Z284C9V1-7 datasheet, PD3Z284C9V1-7 pinout, PD3Z284C9V1-7 application, or PD3Z284C9V1-7 equivalent, key selection criteria include zener voltage tolerance (±6.6%), thermal resistance (250°C/W), cathode-band polarity marking, and derating behavior above +25°C ambient - all critical for precision voltage reference and overvoltage protection in space-constrained automotive ECUs and industrial sensors.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics, while the PowerDI323 package enables high thermal efficiency on standard FR-4 PCBs with recommended pad layout per AP02001.
It delivers 9.1V regulation with ±6.6% tolerance at 5mA, exhibits low dynamic impedance (10Ω typical), and maintains <0.5μA reverse leakage at VR = 6.0V. Temperature coefficient is +3.8mV/°C, enabling predictable drift compensation in analog front-ends and power supply feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1V nominal, 8.5–9.6V range at 5mA - defines regulated output level in shunt regulator circuits |
| Power Dissipation (PD) | 500mW at TA = +25°C - limits continuous current to ~55mA at 9.1V before thermal shutdown |
| Zener Impedance (ZZT) | 10Ω max at 5mA - ensures minimal output voltage variation under dynamic load changes |
| Reverse Leakage (IR) | 0.5μA max at 6.0V - guarantees negligible standby current in battery-powered voltage monitor circuits |
| Thermal Resistance (RθJA) | 250°C/W - requires derating to 300mW above +85°C ambient for sustained operation |
| Temperature Coefficient | +3.8mV/°C - enables predictable VZ drift correction in temperature-compensated references |
| Package | PowerDI®323 - 2.5 × 1.9 × 0.13mm footprint ideal for dense automotive PCB layouts |
Pinout & Package
PowerDI®323 is a two-terminal surface-mount package with cathode band marking on the top surface. Terminals are matte tin-plated copper; polarity is unambiguous via cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side connection in shunt configuration | Connected to ground or lower-potential node; carries full load current during regulation |
| Cathode | Zener breakdown terminal / high-side connection in shunt configuration | Connected to input rail; clamps voltage to 9.1V by sinking excess current to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Ultra-small PowerDI323 footprint | 2.5mm × 1.9mm area saves >40% board space vs. SOD-123 in ECU sensor modules |
| Lead-free & halogen-free | RoHS-compliant with UL 94V-0 flammability rating and no Br/Sb in molding compound |
| Low Zener impedance | 10Ω max ensures <91mV output shift under ±10mA load transients at 9.1V |
Applications
| Automotive Body Control Module (BCM) | Industrial Current-Sense Reference |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z9V1BF-7 | Same 9.1V rating, 250mW PD, SOD-323 package, lower power rating | Not AEC-Q101 qualified; suitable only for commercial-grade consumer electronics | Select when cost sensitivity outweighs automotive reliability requirements |
| BZX384-C9V1,115 | 9.1V, 300mW, SOD-323, ±5% tolerance, higher leakage (1μA @ 6V) | Lacks AEC-Q101 qualification and green compound; used in telecom power supplies | Prefer for legacy designs where SOD-323 footprint compatibility is mandatory |
Compared with D3Z9V1BF-7 and BZX384-C9V1,115, PD3Z284C9V1-7 offers superior thermal performance (500mW vs ≤300mW), automotive qualification, and tighter leakage control - making it the only choice for safety-critical voltage clamping in engine control units and ADAS subsystems.

FAQ
What is the maximum allowable junction temperature for PD3Z284C9V1-7?
The absolute maximum junction temperature is +150°C, with storage temperature matching this range. Derating begins linearly at +25°C ambient, reducing power dissipation by 2mW/°C above that point - resulting in zero usable power at +275°C ambient (though practical operation is limited to +150°C junction per AEC-Q101 stress limits).
How does the PowerDI323 package compare thermally to SOD-123?
PowerDI323 has RθJA = 250°C/W on standard FR-4, versus ~300°C/W for SOD-123. This 17% improvement stems from its exposed copper leadframe and optimized thermal pad layout, enabling higher sustained power in compact automotive modules without heatsinking.
Is PD3Z284C9V1-7 suitable for use in life support equipment?
No. Diodes Incorporated explicitly prohibits use of PD3Z284C9V1-7 in life support devices or systems without written CEO approval. Its qualification covers automotive and industrial applications, but not safety-critical medical implants or resuscitation equipment per the Life Support Notice in DS32239 Rev. 10-3.
What marking code appears on the top surface of PD3Z284C9V1-7?
The top surface is marked "Z0P" or "0P", followed by a two-character date code (e.g., "A9" for September 2014). The cathode band is a visible dark stripe adjacent to the marking - confirming polarity during automated optical inspection and manual placement.
