Product details
Overview
PD3Z284C15-7 from Diodes Incorporated is a 15 V, 500 mW surface-mount Zener diode in PowerDI™323 package, with nominal zener voltage 15 V (min 13.8 V, max 15.6 V) at 5 mA test current, 15 Ω maximum zener impedance, and 0.1 µA maximum reverse leakage at 10.5 V. It serves as precision voltage reference and overvoltage clamp in low-power analog monitoring circuits.
For engineers reviewing the PD3Z284C15-7 datasheet, PD3Z284C15-7 pinout, PD3Z284C15-7 application, or PD3Z284C15-7 equivalent, key selection criteria include zener voltage tolerance (±3.6%), thermal resistance (250 °C/W), AEC-Q101 qualification, RoHS-compliant matte tin terminations, and derating behavior above +25°C ambient.
Technical Context
This Zener diode uses planar die construction for stable breakdown characteristics and low dynamic impedance. Its 15 V nominal regulation is specified at IZT = 5 mA, with temperature coefficient of +9.2 mV/°C - indicating positive drift over temperature - and supports reverse voltage up to 13.0 V before significant leakage onset.
The device operates across –65°C to +150°C junction temperature range and exhibits 250 °C/W thermal resistance when mounted on polyimide PCB per recommended pad layout. Power dissipation linearly derates above +25°C ambient, reaching zero at +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V nominal, 13.8–15.6 V range at 5 mA - defines stable regulation window for reference or clamping |
| Power Dissipation (PD) | 500 mW at TA = +25°C - sets absolute max continuous DC power under ideal cooling |
| Zener Impedance (ZZT) | 15 Ω max at 5 mA - ensures minimal output voltage variation under load current changes |
| Reverse Leakage (IR) | 0.1 µA max at 10.5 V - guarantees negligible standby current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 250 °C/W - determines junction-to-ambient temperature rise per watt dissipated |
| Temperature Coefficient | +9.2 mV/°C - quantifies positive VZ drift with rising temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z15BF-7 | Same 15 V nominal, but 250 mW rating and 30 Ω ZZT; smaller SOD-323 package (1.7 × 1.3 mm) | Lower power handling limits use in <10 mA reference paths; tighter footprint suits ultra-dense layouts | Select when board space is critical and power demand ≤250 mW; verify thermal margin with reduced pad area |
| BZX384-C15,115 | 15 V, 300 mW, 30 Ω ZZT, SOD-323; ±5% VZ tolerance vs. ±3.6% here | Higher leakage (0.5 µA @ 10.5 V); not AEC-Q101 qualified - limited to commercial-grade systems | Choose for cost-sensitive non-automotive designs where ±5% VZ and absence of automotive qualification are acceptable |
Compared with D3Z15BF-7 and BZX384-C15,115, PD3Z284C15-7 delivers higher power headroom (500 mW), lower impedance (15 Ω), tighter voltage tolerance (±3.6%), and automotive-grade reliability - making it optimal for industrial and automotive voltage reference and clamping where stability and ruggedness are prioritized.

FAQ
What is the maximum reverse voltage that can be safely applied before breakdown?
The PD3Z284C15-7 has a nominal zener voltage of 15 V with a guaranteed range of 13.8 V to 15.6 V at 5 mA test current. Breakdown begins near the minimum VZ (13.8 V), and the device is rated for continuous operation up to its specified power limit. Applying reverse voltage below 13.8 V results in only microamp-level leakage current.
Is PD3Z284C15-7 suitable for reflow soldering using standard lead-free profiles?
Yes - PD3Z284C15-7 is rated Moisture Sensitivity Level 1 per J-STD-020D and features matte tin-plated terminations compatible with IPC/JEDEC J-STD-020-compliant lead-free reflow profiles. No pre-baking is required, and it withstands peak temperatures up to 260°C.
How does the +9.2 mV/°C temperature coefficient affect circuit performance?
The +9.2 mV/°C coefficient means VZ increases by approximately 0.92 V over a 100°C rise. In precision references, this drift must be compensated via calibration or circuit topology (e.g., using complementary tempcos). For clamping, it expands the protection window slightly at elevated temperatures.
Why is PD3Z284C15-7 marked as "Not Recommended for New Designs"?
Diodes Incorporated recommends migrating to the newer D3ZxxBF series due to improved consistency, tighter tolerances, and enhanced process control. PD3Z284C15-7 remains fully functional and supported for existing designs, with no obsolescence timeline published as of DS32239 Rev. 10-3 (April 2013).
