Product details
Overview
BZX8850S-C36-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision voltage reference and regulation in space-constrained, low-power circuits. It delivers a nominal 36 V Zener voltage (35.3–36.7 V at IZ = 50 µA), ±2 % tolerance (C-series), 350 Ω dynamic resistance at 5 mA, and operates with only 50 µA test current - enabling ultra-low-bias operation in battery-powered sensor nodes and automotive body electronics.
For engineers reviewing the BZX8850S-C36-QYL datasheet, BZX8850S-C36-QYL pinout, BZX8850S-C36-QYL application, or BZX8850S-C36-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable DFN1006BD-2 (SOD882BD) package for automated optical inspection, 365 mW power rating at 25 °C, and intentional leakage optimization for noise-sensitive analog front-ends.
Technical Context
This device functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener breakdown threshold. Its electrical behavior is characterized at low test currents (50 µA), making it suitable for biasing circuits where quiescent current must remain below 100 µA.
The C-series variant exhibits tighter ±2 % VZ tolerance, lower temperature coefficient (±0.05 mV/K typical), and optimized leakage profile per AN90031 - distinguishing it from the B-series' ±5 % tolerance and higher leakage suppression. Thermal resistance is 340 K/W junction-to-ambient on FR4 PCB, limiting continuous dissipation to 365 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 35.3 V to 36.7 V at IZ = 50 µA - defines precise regulation point for low-current reference applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B36-Q | ±5 % VZ tolerance (34.2–37.8 V), higher leakage suppression, no intentional leakage tuning | Suitable for cost-sensitive industrial controls where ±5 % regulation margin is acceptable | Select when tighter tolerance is unnecessary and lowest possible dark current is required |
| MMSZ5245B-TP | 36 V nominal, ±5 %, SOD-123 package (1.7 mm × 1.3 mm), 500 mW Ptot, no AEC-Q101 qualification | Preferred for non-automotive consumer electronics with larger board area and higher power budgets | Choose only for non-automotive designs needing higher power headroom and legacy footprint compatibility |
Compared with BZX8850S-C36-QYL, the BZX8850S-B36-Q trades tolerance for lower leakage, while MMSZ5245B-TP offers higher power but lacks automotive qualification and miniaturization - making the C36-QYL optimal for AEC-Q101-compliant, space-constrained, low-IQ systems.

FAQ
What is the maximum reverse current (IR) at VR = 30 V for BZX8850S-C36-QYL?
At VR = 30 V and Tj = 25 °C, the typical reverse current is ≤ 0.05 µA. This ultra-low leakage ensures minimal power loss in always-on monitoring circuits and extends battery life in energy-harvesting applications.
Can BZX8850S-C36-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device or an active shunt regulator topology.
Is the cathode marking visible under standard optical inspection?
Yes - the cathode is indicated by a laser-marked bar on the top surface of the DFN1006BD-2 package, positioned adjacent to Pin 1. Its contrast and placement comply with IPC-A-610 Class 2/3 requirements for automated optical inspection.
Does the 365 mW power rating apply at elevated ambient temperatures?
No - the 365 mW rating is valid only at Tamb ≤ 25 °C on a standard FR4 PCB. Derating is required above 25 °C: Rth(j-a) = 340 K/W implies ~1.07 mW/°C reduction, reaching zero dissipation at ~130 °C ambient.
