Product details
Overview
BZX884S-B62-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 62 V Zener voltage with ±2 % tolerance, 120 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-B62-QYL datasheet, BZX884S-B62-QYL pinout, BZX884S-B62-QYL application, or BZX884S-B62-QYL equivalent, this page provides verified electrical parameters, automotive-grade qualification status (AEC-Q101), thermal resistance (340 K/W), forward voltage (≤0.9 V @ 10 mA), and side-wettable flank packaging details essential for SMT reliability validation and board-level ESD/overvoltage design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and line conditions. Its 62 V nominal working voltage targets intermediate bus regulation and transient clamping in 48 V automotive subsystems and industrial power rails.
The device uses silicon planar epitaxial construction with tight process control to achieve ±2 % voltage tolerance and low temperature coefficient (±3.7 mV/K typical). Side-wettable flanks on the DFN1006BD-2 package enable automated optical solder-joint inspection during reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 60.8 V to 63.2 V @ IZ = 2 mA - defines precise clamping threshold for 48 V system overvoltage protection |
| Differential Resistance rdif | 120 Ω typical @ IZ = 2 mA - determines output impedance and voltage regulation stability under load variation |
| Temperature Coefficient SZ | +3.7 mV/K typical - quantifies voltage drift per degree Celsius, critical for high-temp automotive environments |

| Total Power Dissipation Ptot | 365 mW @ Tamb = 25 °C on FR4 PCB - sets maximum continuous clamping energy before thermal derating begins |
| Junction Temperature Tj | −55 °C to +150 °C - supports operation in engine bay and under-hood applications per AEC-Q101 stress testing |
| Forward Voltage VF | ≤0.9 V @ IF = 10 mA - enables use as polarity protection diode in low-drop rectification paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C62-Q | ±5 % tolerance (58.0–66.0 V) vs. ±2 % (60.8–63.2 V); higher max IR (0.05 μA vs. same) | Acceptable where tighter regulation not required; lower cost for non-safety-critical consumer power supplies | Select for cost-sensitive designs where 62 V ±5 % meets system margin requirements |
| MMSZ5259B-TP | 62 V ±5 %, SOD-123 package (1.8 × 1.4 mm), 500 mW Ptot, Rth(j-a) = 300 K/W | Larger footprint but higher power handling; less suitable for ultra-dense automotive PCBs | Choose when higher power dissipation (>365 mW) or legacy SOD-123 layout compatibility is required |

FAQ
What is the maximum reverse voltage the BZX884S-B62-QYL can withstand before breakdown?
The BZX884S-B62-QYL has a nominal Zener voltage of 62 V with a guaranteed breakdown range of 60.8 V to 63.2 V at IZ = 2 mA. Below 60.8 V, it remains in high-impedance reverse blocking mode with ≤0.05 μA leakage at 49.6 V. Breakdown is sharp and repeatable within this specification window.
Does the BZX884S-B62-QYL require a series current-limiting resistor in all applications?
Yes-a series resistor is mandatory to limit Zener current within its 365 mW power rating and prevent thermal runaway. For example, at 75 V transient input, a minimum 210 Ω resistor limits IZ to ~62 mA, keeping power dissipation below 365 mW. The resistor value must be calculated based on worst-case input voltage and desired clamping current.
How does the side-wettable flank feature improve manufacturing yield?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder fillet formation on all four side edges without needing X-ray or destructive cross-section analysis. This enables 100 % inline solder-joint quality screening in high-volume automotive PCB assembly lines.
Can the BZX884S-B62-QYL be used in parallel for higher power handling?
No-Zener diodes should not be paralleled due to mismatched breakdown voltages causing current hogging and thermal instability. For higher power, select a single higher-rated device like the PMLZ62-13-F (62 V, 1 W) or implement active clamping with MOSFETs instead of passive Zener stacking.
