Product details
Overview
BZX884S-C68-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 68 V Zener voltage with ±5 % tolerance, 150 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C68-QYL datasheet, BZX884S-C68-QYL pinout, BZX884S-C68-QYL application, or BZX884S-C68-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low reverse leakage (<0.05 μA at 54.4 V).
Technical Context
This Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across a load by conducting reverse current when input exceeds its breakdown threshold. Its operation relies on controlled avalanche breakdown in silicon, with temperature coefficient of +90 mV/K at IZ = 2 mA - indicating positive drift with rising temperature.
The device uses a planar epitaxial process for tight parameter control and integrates side-wettable flanks to enable solder joint quality verification via AOI. It is rated for continuous operation from −55 °C to +150 °C ambient, with thermal resistance Rth(j-a) = 340 K/W on standard FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 64 V to 72 V (±5 % tolerance); ensures stable regulation within 4 V window at IZ = 2 mA |
| Differential Resistance rdif | 150 Ω typ. at IZ = 2 mA; defines voltage change per mA of current shift, critical for load regulation accuracy |
| Max Power Dissipation Ptot | 365 mW on FR4 PCB; sets absolute upper limit for safe continuous power handling under standard mounting |
| Reverse Current IR | <0.05 μA at VR = 54.4 V; guarantees minimal leakage in standby or pre-breakdown states |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA; enables predictable forward conduction behavior during transient polarity events |
| Junction Temperature Tj | −55 °C to +150 °C operating range; supports under-hood automotive and high-temp industrial environments |
| Package | DFN1006BD-2 (SOD882BD); 1.0 mm × 0.6 mm × 0.47 mm leadless body with side-wettable flanks for reliable reflow and AOI |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B68-Q | ±2 % tolerance (65.6–70.4 V), lower rdif (120 Ω), higher cost | Better regulation accuracy required in precision analog front-ends | Select when tighter voltage tolerance and lower dynamic impedance outweigh cost sensitivity |
| MMSZ5263ET1G | 68 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW rating, no SWF | Higher power handling needed; AOI not required; legacy board compatibility | Choose for manual assembly, higher power margin, or existing SOD-123 footprint reuse |
Compared with BZX884S-C68-QYL, BZX884S-B68-Q offers superior regulation accuracy but lacks cost advantage, while MMSZ5263ET1G trades miniaturization and AOI capability for greater power headroom and broader industry adoption.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX884S-C68-QYL has a nominal Zener voltage of 68 V with ±5 % tolerance, meaning guaranteed breakdown occurs between 64 V and 72 V at IZ = 2 mA. Its absolute maximum reverse voltage is not specified beyond this range; operation above 72 V risks uncontrolled avalanche and thermal runaway unless current-limited externally.
Is this diode suitable for use in reflow soldering processes?
Yes - the DFN1006BD-2 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Nexperia specifies reflow as the only recommended soldering method, with footprint dimensions published for optimal thermal transfer and solder joint formation on FR4 PCBs.
How does the temperature coefficient affect regulation accuracy over temperature?
This part exhibits a +90 mV/K temperature coefficient at IZ = 2 mA, meaning its Zener voltage increases ~6.1 V from −40 °C to +125 °C. For applications requiring tight regulation across temperature, compensation in firmware or external circuitry is necessary - unlike low-tempco variants such as BZX884S-B68-Q (+30 mV/K).
Can this Zener diode replace a TVS diode in surge protection circuits?
No - while it provides clamping, the BZX884S-C68-QYL is rated for 365 mW continuous dissipation and lacks the high peak pulse power capability (e.g., 600 W) of dedicated TVS diodes. It is appropriate for low-energy transients and voltage reference, but not for lightning or ESD-level surge suppression without supplemental protection.
