Product details
Overview
PD3Z284C16Q-7 from Diodes Incorporated is a 16V, 500mW AEC-Q101 qualified Zener diode in PowerDI323 (Type B) package, with nominal zener voltage 16V (min 15.3V, max 17.1V), zener test current 5mA, dynamic impedance 20Ω at IZT, and reverse leakage ≤0.1µA at 11.2V. It serves as precision voltage reference and overvoltage clamp in automotive power supply rails.
For engineers reviewing the PD3Z284C16Q-7 datasheet, PD3Z284C16Q-7 pinout, PD3Z284C16Q-7 application, or PD3Z284C16Q-7 equivalent, key selection criteria include zener voltage tolerance (±4.4%), thermal resistance (250°C/W), AEC-Q101 qualification status, PowerDI323 footprint compatibility, and low leakage performance below 0.1µA at rated VR.
Technical Context
This Zener diode uses planar die construction for stable breakdown characteristics and low temperature coefficient (+10.4 to +14.0 mV/°C). Its ultra-small PowerDI323 (Type B) package enables high-density placement while maintaining 500mW power dissipation under defined PCB layout conditions.
It operates across –65°C to +150°C ambient range and exhibits 200Ω maximum knee impedance (ZZK) at 1mA, supporting reliable regulation in transient-suppression and reference circuits where low dynamic impedance and tight voltage tolerance are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C16,115 (Nexperia) | Same 16V nominal, but SOD-323 package (larger θJA = 350°C/W); 250mW rating | Lower power handling limits use in sustained-clamp scenarios; requires larger PCB copper area | Select if legacy SOD-323 footprint reuse is required and peak power <250mW |
| MMSZ5245B-TP (Micro Commercial Components) | SOD-123 package; 16V nominal, ±5% tolerance, 500mW, but not AEC-Q101 qualified | Not suitable for automotive production without additional qualification testing | Select for industrial prototypes where AEC-Q101 is not mandated and cost is primary constraint |
Compared with BZX384-C16,115 and MMSZ5245B-TP, PD3Z284C16Q-7 uniquely combines AEC-Q101 qualification, 500mW rating in PowerDI323, and ±4.4% voltage tolerance-enabling direct drop-in use in space-constrained automotive ECUs without derating or requalification.

FAQ
What is the maximum reverse voltage (VR) this Zener diode can withstand before breakdown?
The PD3Z284C16Q-7 has a specified maximum reverse current (IR) of 0.1µA at VR = 11.2V, meaning it remains in high-impedance blocking mode up to that voltage. Breakdown begins near its nominal 16V zener voltage at 5mA test current, with guaranteed operation between 15.3V and 17.1V under those conditions.
Is thermal derating required above +25°C ambient?
Yes - the device's 500mW rating applies only at TA = +25°C. Power must be linearly derated above that point using its 250°C/W junction-to-ambient thermal resistance. At +100°C ambient, maximum allowable power drops to 312.5mW, per the published derating curve in DS43436 Rev. 3-2.
Does this part support automated optical inspection (AOI) after placement?
Yes - the PowerDI323 (Type B) package features a clearly visible cathode band and consistent top-surface marking "0W" for PD3Z284C16Q-7, enabling reliable AOI detection. The matte tin finish and flat leadframe geometry also support high-yield solder paste inspection and post-reflow void analysis.
Can PD3Z284C16Q-7 replace PD3Z284C15Q in an existing design?
No - PD3Z284C15Q has a 15V nominal zener voltage (14.3–15.8V range), while PD3Z284C16Q-7 is 16V (15.3–17.1V). The 1V difference affects regulation accuracy and may exceed downstream IC absolute maximum ratings. Verify voltage margin and thermal impact before substitution; no pinout or package change is required.
