Product details
Overview
BZX884S-B68-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 ±2 % 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-B68-QYL datasheet, BZX884S-B68-QYL pinout, BZX884S-B68-QYL application, or BZX884S-B68-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 operates in reverse breakdown mode to maintain stable voltage regulation under varying load and temperature conditions. Its 68 V nominal Zener voltage is specified at IZ = 2 mA, with a positive temperature coefficient of +90 mV/K, enabling predictable thermal drift compensation in bias networks.
The device uses silicon planar epitaxial construction with metallization optimized for low parasitic inductance and high surge current capability. Its ultra-small DFN1006BD-2 footprint (1.0 mm × 0.6 mm × 0.47 mm) supports high-density PCB layouts while maintaining thermal resistance of 340 K/W to ambient on standard FR4.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C68-Q | ±5 % tolerance (vs. ±2 %), higher max rdif (240 Ω), same VZ range and package | Suitable for non-critical biasing where cost optimization outweighs precision | Select when tighter regulation is unnecessary and BOM cost reduction is prioritized |

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX884S-B68-QYL has a nominal Zener voltage of 68 V, with guaranteed breakdown occurring between 66.6 V and 69.4 V at IZ = 2 mA. Its absolute maximum reverse voltage is not rated separately-it is defined by its Zener characteristic, and operation above 69.4 V under regulation conditions will increase power dissipation beyond safe limits unless current is strictly limited.
Is this part suitable for reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended process per Nexperia's documentation. The DFN1006BD-2 package lacks leads and relies on side-wettable flanks for solder joint formation; hand-soldering risks insufficient wetting, voiding, or thermal damage due to localized overheating. Reflow profiles must follow J-STD-20 guidelines for small-body leadless components.
How does the ±2 % tolerance affect circuit performance in precision reference applications?
The ±2 % tolerance translates to a 66.6 V–69.4 V window at 25 °C, resulting in ≤±1.4 V uncertainty in regulated output. In precision biasing, this requires downstream calibration or trimming if sub-1 V accuracy is needed; however, for overvoltage clamping, it ensures consistent trip thresholds across production batches without individual unit adjustment.
Does the marking '3L' on the device body correspond directly to BZX884S-B68-QYL?
Yes-per Table 4 of the datasheet, the marking code '3L' uniquely identifies the BZX884S-B68-QYL variant within the BZX884S-Q series. This two-character code is laser-marked on the top surface adjacent to the cathode bar and is used for traceability and automated optical verification during assembly.
