Product details
Overview
BZX8850S-C5V6-QYL from Nexperia is a low-current Zener voltage regulator diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision biasing and voltage reference in space-constrained, low-power systems. It delivers a nominal 5.6 V regulation at 50 µA test current, with ±2 % tolerance, 400 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-C5V6-QYL datasheet, BZX8850S-C5V6-QYL pinout, BZX8850S-C5V6-QYL application, or BZX8850S-C5V6-QYL equivalent, this device is selected for ultra-low quiescent current regulation, ESD-robust voltage clamping in portable sensors, and stable reference generation in battery-powered microcontroller I/O protection circuits.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 5.32 V to 5.88 V at IZ = 50 µA, exhibiting a temperature coefficient of −2.0 mV/K and typical reverse leakage < 4.0 µA at VR = 4.0 V. Its low 50 µA test current enables operation in sub-100 µA bias networks without compromising regulation accuracy.
The device uses side-wettable flanks for automated optical solder-joint inspection and achieves 340 K/W junction-to-ambient thermal resistance on FR4 PCBs. Its 0.6 mm pitch, 1.0 mm × 0.6 mm footprint supports high-density routing while maintaining 365 mW total power dissipation at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 5.6 V at IZ = 50 µA - precise reference for low-bias analog monitoring circuits |
| Voltage Tolerance | ±2 % - tight regulation band enabling accurate threshold detection in safety-critical inputs |
| Differential Resistance | 400 Ω at IZ = 5 mA - low dynamic impedance ensures stable output under small load variations |
| Forward Voltage | ≤ 0.9 V at IF = 10 mA - minimal forward drop for polarity-sensitive clamp configurations |
| Power Dissipation | 365 mW at Tamb ≤ 25 °C - sufficient headroom for transient overvoltage absorption in 3.3 V/5 V rail protection |
| Junction Temperature | −55 °C to +150 °C - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD HBM ≥ 2 kV |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8840S-C5V6 | Same 5.6 V nominal, ±2 %, but in larger SOD323 package (1.7 mm × 1.3 mm); 500 mW Ptot; no side-wettable flanks | Less suitable for ultra-dense layouts; higher thermal resistance (250 K/W) limits sustained power handling | Select when board assembly lacks AOI capability or requires higher surge margin |
| MMSZ5232B-TP | 5.6 V, ±5 % tolerance; SOD-123 package; 500 mW rating; no AEC-Q101 qualification | Higher voltage variation impacts precision analog sensing; not approved for automotive deployment | Acceptable for cost-sensitive consumer IoT where ±5 % regulation and non-automotive qualification are acceptable |
Compared with BZX8850S-C5V6-QYL, BZX8840S-C5V6 offers higher power margin but sacrifices miniaturization and AOI support, while MMSZ5232B-TP trades tolerance and qualification for lower unit cost-making the QYL variant optimal for space-constrained, automotive-grade, low-quiescent designs.

FAQ
What is the maximum reverse current at 4.0 V for BZX8850S-C5V6-QYL?
The maximum reverse current (IR) is 4.0 µA at VR = 4.0 V and Tj = 25 °C, per Table 8 electrical characteristics. This low leakage supports micropower operation in battery-backed systems and ensures minimal loading on high-impedance reference nodes.
Can BZX8850S-C5V6-QYL be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages; paralleling causes current hogging and thermal runaway. For higher power, use a single higher-rated device like BZX8840S-C5V6 or add external series resistance to balance current sharing.
Is the cathode marking visible under standard optical inspection?
Yes-the cathode is marked by a bar on the top surface of the DFN1006BD-2 package, and the side-wettable flanks enable reliable automated optical inspection (AOI) of solder joints without requiring X-ray or cross-section analysis.
How does the −2.0 mV/K temperature coefficient affect regulation accuracy over temperature?
At 5.6 V nominal, a −2.0 mV/K coefficient results in −0.224 V drift over a 112 K range (−40 °C to +72 °C), or ~4 % deviation. For tighter accuracy, pair with a positive-tempco component or use in closed-loop feedback where drift is compensated by system gain.
