Product details
Overview
PD3Z284C10-7 from Diodes Incorporated is a 10 V, 500 mW surface-mount Zener diode in PowerDI™323 package, featuring 9.4–10.6 V zener voltage tolerance at 5 mA test current, 10 Ω maximum zener impedance, and AEC-Q101 qualification for automotive-grade reliability. It provides precision voltage regulation in low-power biasing and reference circuits.
For engineers reviewing the PD3Z284C10-7 datasheet, PD3Z284C10-7 pinout, PD3Z284C10-7 application, or PD3Z284C10-7 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (250 °C/W), reverse leakage (<0.2 µA at 7.0 V), temperature coefficient (±4.5 mV/°C), and RoHS-compliant "green" molding compound.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 10 V regulation point, specified at IZT = 5 mA and characterized up to 2 mA for higher-voltage variants. Its planar die construction ensures stable voltage regulation under transient conditions and low thermal drift.
The device exhibits a negative temperature coefficient of +4.5 mV/°C (typical) and maintains ≤0.2 µA reverse current at 7.0 V, enabling use in low-quiescent-current voltage references. Its PowerDI323 package delivers 250 °C/W junction-to-ambient thermal resistance on standard polyimide PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V nominal, 9.4–10.6 V range at 5 mA - defines precise regulation threshold for feedback or reference nodes |

| Zener Impedance (ZZT) | 10 Ω max at 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | 0.2 µA max at 7.0 V - enables ultra-low standby current in battery-backed circuits |
| Thermal Resistance (RθJA) | 250 °C/W - requires minimal copper area for thermal management on standard FR-4 |
| Temperature Coefficient | +4.5 mV/°C - allows predictable drift compensation in temperature-sensitive references |
| Package | PowerDI323 - 2.5 × 1.9 mm footprint, compatible with high-density SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z10BF-7 | Same 10 V rating, 500 mW, but in SOD-323 package; 15 Ω ZZT, 0.5 µA IR at 7 V | Larger footprint (3.5 × 1.9 mm); less suitable for ultra-dense layouts | Preferred where legacy SOD-323 placement exists and tighter VZ tolerance is not required |
| BZX384-C10,115 | 10 V, 300 mW, SOD-323; ±5% VZ tolerance; 30 Ω ZZT; 0.1 µA IR at 7.6 V | Lower power rating limits use in sustained 5 mA biasing; no AEC-Q101 qualification | Cost-optimized alternative for non-automotive consumer applications with relaxed reliability needs |
Compared with PD3Z284C10-7, D3Z10BF-7 trades slightly higher impedance for broader industry adoption, while BZX384-C10 offers lower leakage but lacks automotive qualification and thermal robustness - making PD3Z284C10-7 optimal for space-constrained, high-reliability designs requiring AEC-Q101 validation.

FAQ
What is the maximum steady-state power dissipation for PD3Z284C10-7?
The PD3Z284C10-7 is rated for 500 mW continuous power dissipation at 25°C ambient when mounted on a polyimide PCB with the recommended pad layout per Diodes Incorporated Application Note AP02001. Derating begins linearly above 25°C at 2 mW/°C, reaching zero at 125°C ambient.
Does PD3Z284C10-7 have automotive qualification?
Yes - PD3Z284C10-7 is qualified to AEC-Q101 standards for high-reliability automotive applications. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life, confirming suitability for under-hood and cabin electronics.
How does the PowerDI323 package compare to SOD-123 in size and thermal performance?
PowerDI323 measures 2.5 × 1.9 mm, ~35% smaller than SOD-123 (3.7 × 1.6 mm). Its thermal resistance is 250 °C/W versus ~300 °C/W for SOD-123 on identical board layouts, due to optimized copper leadframe exposure and shorter internal thermal paths.
Is PD3Z284C10-7 recommended for new designs?
No - Diodes Incorporated explicitly marks this series as "NOT RECOMMENDED FOR NEW DESIGNS" in DS32239 Rev. 10-3, advising migration to the D3ZxxBF series. However, PD3Z284C10-7 remains fully supported for existing production and legacy BOM continuity.
