Product details
Overview
PD3Z284C13-7 from Diodes Incorporated is a 13V, 500mW surface-mount Zener diode in PowerDI™323 package, with nominal Zener voltage 13V (min 12.4V, max 14.1V) at 5mA test current, 10Ω maximum Zener impedance, and 0.1µA maximum reverse leakage at 8.0V. It delivers precision voltage regulation in compact power management circuits for automotive body control modules and industrial sensor signal conditioning.
For engineers reviewing the PD3Z284C13-7 datasheet, PD3Z284C13-7 pinout, PD3Z284C13-7 application, or PD3Z284C13-7 equivalent, key selection criteria include Zener voltage tolerance (±4.6%), thermal resistance (250°C/W), AEC-Q101 qualification, RoHS-compliant "green" molding compound, and cathode-band polarity marking for unambiguous orientation during automated placement.
Technical Context
This Zener diode employs planar die construction to ensure stable breakdown characteristics across temperature and lifetime. Its 13V regulation point is optimized for mid-range reference and clamp applications where tight voltage control under low-current bias (5mA IZT) is required without excessive power dissipation.
The device operates within -65°C to +150°C ambient range and exhibits a negative temperature coefficient of +7.0 mV/°C - enabling predictable drift compensation in analog feedback loops. Its 10Ω dynamic impedance at 5mA supports stable regulation even with moderate load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V nominal, 12.4–14.1 V range at 5 mA - defines regulated output level with ±4.6% tolerance |
| Power Dissipation (PD) | 500 mW - sets maximum continuous DC power handling on standard PCB layout |
| Zener Impedance (ZZT) | 10 Ω max at 5 mA - ensures minimal output voltage variation under small-signal load changes |
| Reverse Leakage (IR) | 0.1 µA max at 8.0 V - guarantees negligible standby current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 250 °C/W - determines junction temperature rise above ambient under full load |
| Temperature Coefficient | +7.0 mV/°C - quantifies voltage drift per degree Celsius for thermal error budgeting |
| Package | PowerDI™323 - 2.5 × 1.9 mm footprint enables high-density routing in space-constrained layouts |
Pinout & Package
PowerDI™323 is a 2-terminal surface-mount package with cathode band marking on the top surface. The anode and cathode are accessed via two coplanar gull-wing leads spaced 0.65 mm apart (E dimension), compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common reference node in reverse-bias regulation | Connected to system ground or lower-potential rail when used as shunt regulator |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse-bias operation | Provides stable 13V reference point; marked by visible band for orientation verification |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified reliability | Validated for automotive under-hood environments including thermal cycling and humidity exposure |
| Lead-free & halogen-free construction | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020D Level 1 moisture sensitivity |
| Ultra-small PowerDI™323 footprint | 2.5 mm × 1.9 mm outline reduces PCB area by >40% vs. SOD-123 while maintaining 500 mW rating |
| Planar die process | Delivers consistent Zener voltage distribution and low parametric shift over time and temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z13BF-7 | Same 13V rating, 500 mW, but in SOD-323 package; 15Ω ZZT vs. 10Ω | Slightly higher dynamic impedance affects regulation stability under fast load steps | Preferred for legacy SOD-323 board reuse; less suitable for high-precision analog feedback |
| BZX384-C13,115 | 13V, 300 mW in SOD-323; 20Ω ZZT; not AEC-Q101 qualified | Limited power handling and no automotive qualification restrict use to commercial-grade systems | Cost-optimized alternative for non-automotive consumer electronics with relaxed reliability requirements |
Compared with D3Z13BF-7 and BZX384-C13,115, PD3Z284C13-7 offers superior Zener impedance (10Ω), AEC-Q101 qualification, and identical PowerDI™323 footprint - making it the optimal choice for new automotive and industrial designs requiring robust, space-efficient voltage reference.

FAQ
What is the maximum reverse voltage this Zener can safely clamp?
The PD3Z284C13-7 is rated for 13V nominal Zener voltage with a 14.1V maximum at 5mA test current. Its absolute maximum reverse voltage is defined by its 13V breakdown specification - exceeding 14.1V risks entering uncontrolled avalanche or thermal runaway unless current is strictly limited by external series resistance.
Is this part suitable for use in automotive under-hood applications?
Yes - PD3Z284C13-7 is qualified to AEC-Q101 standards and rated for operation from -65°C to +150°C. Its PowerDI™323 package, green molding compound, and matte tin terminations meet automotive solderability and corrosion resistance requirements per MIL-STD-202.
How does the 250°C/W thermal resistance impact PCB layout?
With RθJA = 250°C/W, dissipating 500mW raises junction temperature by 125°C above ambient. To maintain TJ ≤ 150°C at 75°C ambient, the PCB must provide ≥1.2 cm² of 1-oz copper pour connected to both terminals - per Diodes' AP02001 recommended pad layout.
Why is this part marked "NOT RECOMMENDED FOR NEW DESIGNS"?
Diodes Incorporated recommends migrating to the D3ZxxBF series due to improved Zener impedance consistency and tighter voltage tolerances. PD3Z284C13-7 remains fully functional and supported, but new designs should evaluate D3Z13BF-7 for enhanced performance and long-term supply assurance.
