Product details
Overview
BZX8850S-C75-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision biasing and voltage reference in space-constrained, low-power circuits. It delivers a nominal 75 V Zener voltage (C-tolerance, ±5 %), operates at 50 μA test current, and features 365 mW total power dissipation in a DFN1006BD-2 (SOD882BD) package - ideal for automotive sensor signal conditioning and portable battery-powered voltage stabilization.
For engineers reviewing the BZX8850S-C75-QYL datasheet, BZX8850S-C75-QYL pinout, BZX8850S-C75-QYL application, or BZX8850S-C75-QYL equivalent, this page provides verified electrical characteristics, AEC-Q101 qualification status, thermal resistance (340 K/W), side-wettable flank solderability, and real-world use cases in automotive ECUs and low-leakage analog front-ends.
Technical Context
This device functions as a two-terminal reverse-biased voltage reference with specified Zener voltage (VZ = 75 V, C-grade tolerance), differential resistance (rdiff ≤ 400 Ω at IZ = 2 mA), and temperature coefficient (SZ = +5.7 mV/K). Its low 50 μA test current enables stable regulation in micro-power systems where quiescent current must be minimized.
Qualified to AEC-Q101, it supports operation from −55 °C to +150 °C ambient, with junction temperature up to 150 °C and non-repetitive peak reverse power dissipation of 40 W (100 μs pulse). The DFN1006BD-2 package features side-wettable flanks for automated optical solder-joint inspection in automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 75 V - precise voltage reference point for overvoltage clamping and bias generation |
| Tolerance | ±5 % (C-series) - ensures predictable regulation across production lots without binning |
| IZ test current | 50 μA - enables stable operation in ultra-low-power circuits such as battery-backed RTCs |
| Ptot | 365 mW - sufficient for continuous regulation in SMT-mounted automotive control modules |
| rdiff | ≤ 400 Ω at IZ = 2 mA - maintains tight voltage regulation under small load variations |
| SZ | +5.7 mV/K - positive temperature coefficient allows compensation in multi-diode reference strings |
| Rth(j-a) | 340 K/W - defines thermal derating curve on standard FR4 PCB with single-sided copper |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm, with side-wettable flanks for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node; marking bar on top surface identifies this terminal |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); reverse-biased during regulation |
Key Features

Applications
| Automotive Sensor Biasing | Portable Device Voltage Reference |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B75-Q | Nominal 75 V, ±2 % tolerance (B-series), rdiff ≤ 350 Ω at IZ = 2 mA | Higher precision required in metrology-grade references; tighter tolerance increases cost | Select when absolute voltage accuracy > ±2 % is mandatory and leakage optimization is secondary |
| MMSZ5269BT1G | 75 V nominal, ±5 %, SOD-123 package (2.7 mm × 1.6 mm), Ptot = 500 mW, Rth(j-a) = 300 K/W | Larger footprint, higher power handling, no side-wettable flanks or AEC-Q101 qualification | Choose for non-automotive industrial designs needing higher dissipation and legacy footprint compatibility |
Compared with BZX8850S-C75-QYL, the BZX8850S-B75-Q offers tighter voltage tolerance but lacks the intentional leakage optimization for noise-sensitive analog paths, while MMSZ5269BT1G trades miniaturization and automotive qualification for higher power margin and broader industry acceptance.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-C75-QYL?
The nominal Zener voltage is 75 V with ±5 % tolerance, meaning guaranteed breakdown occurs between 71.25 V and 78.75 V at IZ = 50 μA. Absolute maximum reverse voltage is not defined; operation beyond VZ + 5 % risks exceeding power limits and thermal runaway under sustained bias.
Does BZX8850S-C75-QYL support reflow soldering with standard lead-free profiles?
Yes - its DFN1006BD-2 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. Side-wettable flanks enable full solder-joint inspection using automated optical equipment per automotive manufacturing standards.
How does the "intentional minor rise of leakage current" benefit circuit performance?
This controlled increase in reverse leakage (per AN90031) reduces minority-carrier lifetime, yielding faster turn-off response and lower high-frequency noise in feedback loops - particularly valuable in switched-mode power supply references and precision ADC bias networks.
Can BZX8850S-C75-QYL replace older BZX8850S-C75 variants without layout changes?
Yes - BZX8850S-C75-QYL uses the identical DFN1006BD-2 package, pinout, and thermal footprint as prior revisions. The "-QYL" suffix denotes tape-and-reel packaging with enhanced moisture sensitivity level (MSL) control, requiring no PCB redesign or process adjustment.
