Product details
Overview
PD3Z284C6V2-7 from Diodes Incorporated is a 0.5W surface-mount Zener diode in PowerDI323 (Type B) package, rated for 6.2V nominal zener voltage at 5mA test current, with ±0.4V tolerance (5.8–6.6V), 10Ω max zener impedance at IZT, and 3µA max reverse leakage at 4.0V. It is AEC-Q101 qualified for automotive-grade reliability and used for precision voltage regulation in low-power sensor biasing circuits.
For engineers reviewing the PD3Z284C6V2-7 datasheet, PD3Z284C6V2-7 pinout, PD3Z284C6V2-7 application, or PD3Z284C6V2-7 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (250°C/W), junction-to-ambient power derating behavior, and compliance with automotive reliability standards.
Technical Context
This Zener diode employs planar die construction for stable breakdown characteristics and low dynamic impedance. Its 6.2V nominal zener voltage exhibits a +0.4 mV/°C temperature coefficient, enabling predictable drift over -65°C to +150°C operating range.
The device delivers 500mW power dissipation on standard polyimide PCB with recommended pad layout, and maintains ≤3µA reverse current at 4.0V - critical for low-leakage reference and protection circuits in battery-powered systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C6V2,215 (Nexperia) | Same 6.2V nominal, but 350mW PD, 40Ω ZZT, and SOD323 package (2.7 × 1.7mm) | Lower power handling and higher impedance limit use in high-accuracy references; larger footprint affects dense layouts | Select when legacy SOD323 footprint compatibility is required and 250mW derated power suffices |
| MMSZ4687-7-F (Diodes Inc.) | Identical 6.2V rating, but 350mW PD, 15Ω ZZT, and SOD123 package (3.7 × 1.6mm) | Higher thermal resistance (350°C/W) reduces usable power at elevated ambient; wider body increases board area | Prefer for designs already using SOD123 land patterns and where 15Ω impedance meets system stability requirements |
Compared with BZX384-C6V2,215 and MMSZ4687-7-F, PD3Z284C6V2-7 delivers superior power density (500mW in smallest footprint), lowest zener impedance (10Ω), and AEC-Q101 qualification - making it optimal for next-generation automotive and industrial sensing nodes demanding reliability and miniaturization.

FAQ
What is the maximum allowable power dissipation for PD3Z284C6V2-7 at 100°C ambient temperature?
Per the power derating curve in DS30702 Rev. 11-2, the device's power dissipation must be linearly reduced from 500mW at 25°C to zero at 150°C. At 100°C ambient, allowable power is 375mW - calculated as 500mW × (1 − (100−25)/125). This assumes mounting on a polyimide PCB with Diodes' recommended pad layout.
Does PD3Z284C6V2-7 support reflow soldering per JEDEC J-STD-020?
Yes - PD3Z284C6V2-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and subjected to standard Pb-free reflow profiles (peak 260°C) without preconditioning or baking. The matte tin finish ensures reliable wetting during soldering.
How does the +0.4 mV/°C temperature coefficient impact long-term voltage reference stability?
The +0.4 mV/°C coefficient means VZ increases by 0.4mV per °C rise in junction temperature. Over a 100°C range (−40°C to +60°C ambient), this yields ~40mV drift - acceptable for non-critical biasing but requires compensation in metrology-grade references. The coefficient is measured at IZT = 5mA and applies only within specified operating current.
Can PD3Z284C6V2-7 be used as a replacement for older PD3Z284C6V2 devices without the "-7" suffix?
No - the "-7" suffix denotes packaging in 3000-piece tape-and-reel format per PowerDI323 (Type B) specification. Devices without "-7" were shipped in bulk or alternate packaging and may reflect pre-2016 PowerDI323 (non-Type B) construction. Mechanical and electrical specs match, but Type B revision includes updated mold compound and leadframe finish per RoHS 2 and halogen-free requirements.
