Product details
Overview
BZX8850S-B7V5-QYL from Nexperia is a low-current Zener voltage regulator diode in an ultra-small DFN1006BD-2 (SOD882BD) package, designed for precision biasing and voltage reference in space-constrained, low-power circuits. It delivers a nominal 7.5 V regulation at 50 µA test current, with ±2 % tolerance, 80 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive signal conditioning and sensor supply rails.
For engineers reviewing the BZX8850S-B7V5-QYL datasheet, BZX8850S-B7V5-QYL pinout, BZX8850S-B7V5-QYL application, or BZX8850S-B7V5-QYL equivalent, this page provides verified package mapping, thermal resistance (340 K/W), leakage behavior (≤0.1 µA at 5.7 V), cathode/anode polarity confirmation, and automotive-grade reliability context - all critical for battery-powered IoT nodes, automotive body control modules, and portable instrumentation design.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 7.35 V to 7.65 V at IZ = 50 µA, exhibiting a positive temperature coefficient of +2.5 mV/K. Its low 50 µA test current enables stable regulation under micro-power conditions where traditional Zeners draw excessive quiescent current.
The device features side-wettable flanks for automated optical solder-joint inspection and achieves 365 mW total power dissipation on FR4 PCB with single-sided copper. Its 150 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments without derating at ambient temperatures up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Tolerance | ±2 % (B-series); ensures tight voltage accuracy for reference-sensitive ADC biasing and comparator thresholds |
| Differential Resistance | 80 Ω (max at IZ = 5 mA); maintains <15 mV output variation across 1 mA load current shifts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8840S-B7V5 | Same 7.5 V, ±2 %, but in larger SOD323 package (1.7 mm × 1.3 mm); 500 mW Ptot; no AEC-Q101 qualification | Suitable for non-automotive industrial PCBs where board space is less constrained and qualification not required | Select when higher power margin (500 mW vs. 365 mW) is needed and AEC-Q101 is unnecessary |
| MMSZ5236B | 7.5 V, ±5 % tolerance; SOD-123 package; 500 mW rating; no side-wettable flanks; not AEC-Q101 qualified | Used in cost-sensitive consumer electronics where ±5 % tolerance and manual AOI suffice | Choose only for non-automotive, non-space-constrained designs requiring lowest unit cost |
Compared with BZX8850S-B7V5-QYL, BZX8840S-B7V5 offers higher power headroom but lacks automotive qualification and miniaturization; MMSZ5236B trades tolerance, reliability, and package capability for cost - making the BZX8850S-B7V5-QYL optimal for AEC-Q101-compliant, high-density automotive and medical designs.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-B7V5-QYL?
The device exhibits a nominal Zener voltage of 7.5 V, with guaranteed breakdown occurring between 7.35 V and 7.65 V at 50 µA test current. Below 7.35 V, reverse leakage remains ≤0.1 µA; sustained operation above 7.65 V risks exceeding specified differential resistance and thermal limits.
Can BZX8850S-B7V5-QYL be used in series or parallel configurations?
Series connection is permissible for higher voltage references, provided current matching and thermal coupling are managed. Parallel use is strongly discouraged due to mismatched Zener impedances causing current hogging - confirmed by its 80 Ω typical rdiff and lack of matched binning data in the datasheet.
Does the side-wettable flank design affect solder reflow profile requirements?
Yes - the DFN1006BD-2 package requires adherence to Nexperia's recommended reflow profile (peak 260 °C, 30–60 s above 217 °C), with controlled ramp rates to prevent voiding. The side-wettable flanks enable post-reflow AOI but do not relax thermal constraints versus standard DFN packages.
How does the B-series differ from C-series variants in the same voltage grade?
BZX8850S-B7V5-QYL uses tighter ±2 % tolerance (vs. C-series ±5 %), lower differential resistance (80 Ω vs. 150 Ω), and is optimized for low-current stability. C-series parts exhibit higher leakage and broader voltage spread - making the B-series preferred for precision reference applications.
