Product details
Overview
PD3Z284C3V6-7 from Diodes Incorporated is a 3.6 V, 500 mW surface-mount Zener diode in PowerDI™323 package, featuring 90 Ω maximum Zener impedance at 5 mA test current, <5 µA reverse leakage at 1.0 V, and AEC-Q101 qualification for automotive-grade reliability-used for precision voltage reference and overvoltage protection in low-power sensor signal conditioning circuits.
For engineers reviewing the PD3Z284C3V6-7 datasheet, PD3Z284C3V6-7 pinout, PD3Z284C3V6-7 application, or PD3Z284C3V6-7 equivalent, key selection criteria include nominal Zener voltage tolerance (±5.6%), thermal resistance (250 °C/W), cathode-band polarity marking, and compatibility with reflow soldering per MIL-STD-202.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across 3.4–3.8 V at 5 mA test current. Its planar die construction ensures stable temperature coefficient (–3.5 mV/°C) and low dynamic impedance, enabling accurate clamping in analog front-end bias networks.
The device is rated for –65 °C to +150 °C operation and derates linearly above 25 °C ambient, delivering 500 mW at TA = 25 °C and ~200 mW at TA = 125 °C per the published power derating curve. Moisture sensitivity level is Level 1 per J-STD-020D.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, 3.4–3.8 V range at 5 mA - defines precise clamping threshold for 3.3 V rail protection |
| Power Dissipation | 500 mW at 25 °C ambient - supports continuous operation in compact PCB layouts without forced cooling |
| Zener Impedance (ZZT) | 90 Ω max at 5 mA - ensures minimal voltage shift under varying load currents in reference circuits |
| Reverse Leakage (IR) | <5 µA at 1.0 V - prevents significant error current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 250 °C/W - requires careful thermal pad design on polyimide PCB per AP02001 layout guidelines |
| Temperature Coefficient | –3.5 mV/°C - enables predictable drift compensation in temperature-stable references |
| Package | PowerDI™323 - 2.5 × 1.9 mm footprint with 0.3 mm typical height, optimized for automated placement |
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 / Zener cathode reference ground | Connected to circuit ground or lower-potential node; forms reference return path |
| Cathode | Reverse-biased Zener terminal / voltage clamp input | Connected to protected node (e.g., MCU I/O line); conducts when voltage exceeds 3.6 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use with extended temperature cycling and HTRB stress testing |
| Green molding compound | Halogen-free (no Br, Sb), UL 94V-0 rated - meets RoHS and environmental compliance mandates |
| Planar die construction | Enables tight VZ tolerance and repeatable Zener impedance across production lots |
| Moisture Sensitivity Level 1 | No baking required before reflow - simplifies SMT assembly and reduces process risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D3Z3V6BF-7 | Same 3.6 V nominal, but 250 mW rating and 30 Ω ZZT; smaller SOD-323 package (1.7 × 1.3 mm) | Better suited for space-constrained designs where power dissipation ≤250 mW is acceptable | Select when board area is critical and thermal budget allows lower power handling |
| BZX384-C3V6,115 | 3.6 V, 300 mW, 90 Ω ZZT, SOD-323 package; ±5% tolerance, not AEC-Q101 qualified | Lacks automotive qualification and has higher RθJA (~350 °C/W), limiting high-temp reliability | Acceptable for commercial-grade consumer products where AEC-Q101 is not mandated |
Compared with PD3Z284C3V6-7, D3Z3V6BF-7 offers superior Zener impedance in a smaller footprint but sacrifices 50% power capability, while BZX384-C3V6,115 trades automotive reliability for cost and availability in non-automotive volume production.

FAQ
Is PD3Z284C3V6-7 suitable for reflow soldering?
Yes. PD3Z284C3V6-7 is qualified for lead-free reflow soldering per JEDEC J-STD-020D Level 1 moisture sensitivity. Its matte tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements, and the PowerDI™323 package withstands peak temperatures up to 260 °C.
What is the maximum operating temperature for continuous use?
The device is rated for continuous operation from –65 °C to +150 °C junction temperature. At ambient temperatures above 25 °C, power must be derated linearly per Figure 1 in DS32239 Rev. 10–3, reaching ~200 mW at 125 °C ambient on a standard polyimide PCB.
How does the –3.5 mV/°C temperature coefficient affect circuit accuracy?
This negative coefficient means VZ decreases by 3.5 mV per °C rise in junction temperature. For a 3.6 V Zener, this yields ~0.1% drift per 10 °C - acceptable in most non-precision references but requires compensation in high-accuracy systems above 85 °C ambient.
Why is PD3Z284C3V6-7 marked as "Not Recommended for New Designs"?
Diodes Incorporated recommends migrating to the D3ZxxBF series due to improved Zener impedance, tighter tolerances, and enhanced thermal performance. PD3Z284C3V6-7 remains fully supported for legacy production and existing designs with validated performance.
