Product details
Overview
PD3Z284C2V7-7 from Diodes Incorporated is a 2.7 V, 500 mW surface-mount Zener diode in PowerDI™323 package, featuring 2.5–2.9 V zener voltage tolerance at 5 mA test current, 450 Ω maximum zener impedance, and AEC-Q101 qualification for automotive-grade reliability. It provides precise low-voltage regulation in space-constrained power management circuits.
For engineers reviewing the PD3Z284C2V7-7 datasheet, PD3Z284C2V7-7 pinout, PD3Z284C2V7-7 application, or PD3Z284C2V7-7 equivalent, key selection criteria include zener voltage accuracy at low test current (5 mA), thermal resistance (250 °C/W), reverse leakage (≤20 µA at 1.0 V), and automotive qualification status.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics, while the PowerDI323 package enables high thermal efficiency on standard PCB layouts.
The device exhibits a negative temperature coefficient of –3.5 mV/°C, supporting predictable drift behavior in temperature-sensitive references. With 1.0 µA maximum reverse current at VR = 1.0 V and 20 µA at VR = 1.0 V, it delivers tight leakage control for low-power biasing applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z2V7BF-7 | Same 2.7 V rating, 250 mW PD, SOD-923 package (1.0 × 0.6 × 0.5 mm) | Smaller footprint but higher RθJA (350 °C/W); lower power handling | Select for ultra-dense layouts where 250 mW derating is acceptable |
| BZX384-B2V7,115 | 2.7 V, 300 mW, SOD-323 package; ±5% tolerance vs. ±7.4% for PD3Z284C2V7-7 | Higher leakage (50 µA @ 1 V); not AEC-Q101 qualified | Select for cost-sensitive consumer applications without automotive reliability requirements |
Compared with D3Z2V7BF-7 and BZX384-B2V7,115, PD3Z284C2V7-7 offers superior automotive qualification, higher power margin (500 mW), and tighter zener impedance control-critical for precision reference stability in harsh environments.

FAQ
What is the maximum allowable zener test current for PD3Z284C2V7-7?
The datasheet specifies IZT = 5 mA as the standardized test condition for zener voltage measurement. Exceeding this current continuously risks exceeding the 500 mW power limit, especially above 25°C ambient. Derating per Figure 1 is required - at 85°C ambient, max IZ drops to ~3.5 mA to stay within safe operating area.
Is PD3Z284C2V7-7 suitable for use in new automotive designs?
No - the official Diodes datasheet explicitly states "NOT RECOMMENDED FOR NEW DESIGNS" and directs users to the newer D3ZxxBF series. While fully functional and AEC-Q101 qualified, PD3Z284C2V7-7 is legacy; new designs should adopt D3Z2V7BF-7 for improved thermal performance and active product support.
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 typical SOD-123. This 17% improvement stems from its exposed copper leadframe and optimized thermal pad layout. The smaller footprint (2.5 × 1.9 mm vs. 3.7 × 1.6 mm) also allows denser placement without sacrificing thermal performance.
What does the "C" in PD3Z284C2V7-7 signify?
The "C" denotes the Zener voltage tolerance grade: ±7.4% (2.5–2.9 V) at IZT = 5 mA. Diodes uses "C" for this tolerance band across the PD3Z284Cx series; other grades include "B" (±5%) and "A" (±2%). The "2V7" explicitly codes the 2.7 V nominal voltage, and "-7" indicates 3000-piece tape-and-reel packaging.
