Product details
Overview
BZX8850S-C7V5-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 7.5 V Zener voltage at 50 µA test current, with ±2 % tolerance (C-series), 80 Ω differential resistance at 5 mA, and 2.5 mV/K temperature coefficient - optimized for battery-powered sensors and automotive body electronics.
For engineers reviewing the BZX8850S-C7V5-QYL datasheet, BZX8850S-C7V5-QYL pinout, BZX8850S-C7V5-QYL application, or BZX8850S-C7V5-QYL equivalent, this device is selected for ultra-low-bias voltage reference, ESD-robust signal-level clamping, and AEC-Q101-compliant automotive subsystems where SOD882BD package side-wettable flanks enable reliable reflow inspection.
Technical Context
This Zener diode operates in reverse breakdown mode with specified characteristics at IZ = 50 µA, enabling stable regulation under micro-power conditions unsuitable for conventional Zeners. Its intentional minor leakage rise improves switching speed and reduces noise per AN90031, making it suitable for dynamic biasing in analog front-ends.
The DFN1006BD-2 (SOD882BD) package features side-wettable flanks for automated optical solder-joint inspection, and its thermal resistance of 340 K/W (junction-to-ambient, FR4 PCB) supports operation up to 150 °C junction temperature - critical for under-hood automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.13 V to 7.88 V at IZ = 50 µA - tight ±2 % tolerance ensures accurate reference in low-current bias networks |
| Differential Resistance (rdiff) | 80 Ω max at IZ = 5 mA - low impedance maintains regulation stability across small load variations |
| Temperature Coefficient (SZ) | +2.5 mV/K - positive TC enables predictable drift compensation in mixed-TC reference designs |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - low conduction loss supports dual-use as clamp and forward-biased protection element |
| Reverse Current (IR) | 0.1 µA max at VR = 5.7 V - ultra-low leakage preserves battery life in always-on monitoring circuits |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C on standard FR4 - sufficient headroom for transient surges without derating in compact layouts |
| Junction Temperature (Tj) | −55 °C to +150 °C - qualified for extended-temperature automotive environments including engine control units |
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 assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; polarity marking bar identifies cathode for correct PCB orientation and reverse-bias operation |
| 2 | Anode (A) | Ground or lower-potential reference point; forms the return path during Zener conduction and defines breakdown direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including body control modules and sensor interfaces requiring stress-tested reliability |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on ultra-fine-pitch DFN packages without X-ray |
| Low test current specification | Characterized at 50 µA - supports regulation in µA-level bias rails typical of IoT sensor nodes and wake-up circuits |
| Optimized leakage profile | Intentional minor IR increase (per AN90031) reduces switching noise and improves transient response in feedback paths |
| Ultra-compact footprint | 0.65 mm pitch, 0.6 mm width - saves >60 % board area vs. traditional SOD-323 Zeners in high-density automotive ECUs |
Applications

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-B7V5-Q | ±5 % tolerance (B-series), higher leakage (1 µA at 5.7 V), same 7.5 V nominal VZ | Suitable for non-critical biasing where cost sensitivity outweighs precision; not recommended for metrology-grade references | Select when budget constraints dominate and ±5 % regulation error is acceptable in power supply feedback loops |
| MMSZ5236B-7-F | Same 7.5 V nominal, ±5 % tolerance, SOD-123 package (2.7 mm × 1.4 mm), 500 mW Ptot | Larger footprint limits use in ultra-dense layouts; higher power rating suits higher-current regulation | Choose for legacy designs using SOD-123 footprints or where thermal margin >365 mW is required for sustained dissipation |
Compared with BZX8850S-C7V5-QYL, the B-series variant trades precision for cost in non-automotive roles, while MMSZ5236B-7-F offers higher power but sacrifices board-area efficiency and AEC-Q101 compliance - making the C7V5-QYL optimal for next-gen automotive and portable systems demanding miniaturization and qualification.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-C7V5-QYL?
The device exhibits sharp Zener breakdown at its nominal 7.5 V working voltage, with guaranteed VZ between 7.13 V and 7.88 V at IZ = 50 µA. Below 5.7 V reverse bias, leakage remains ≤0.1 µA - no defined "maximum non-breakdown voltage" is specified, as operation is intended within the regulated breakdown region.
Can BZX8850S-C7V5-QYL be used in forward-bias applications?
Yes - it functions as a standard silicon diode in forward bias, with VF ≤ 0.9 V at 10 mA. This dual capability supports combined use as both a low-voltage clamp and a low-drop rectifier in compact power management circuits, though its primary design intent is reverse-bias Zener regulation.
Is the SOD882BD package compatible with standard reflow profiles?
Yes - Nexperia provides validated reflow soldering footprints for the DFN1006BD-2 package, specifying 0.6 mm pad width and 0.7 mm length with 0.4 mm solder mask clearance. The side-wettable flanks ensure compatibility with industry-standard AOI systems after JEDEC J-STD-020-compliant reflow.
How does the "intentional minor rise of leakage current" improve performance?
Per Application Note AN90031, this controlled leakage enhancement reduces minority-carrier lifetime, yielding faster turn-off response and lower switching noise - particularly beneficial in feedback paths of DC-DC converters and precision analog comparators where Zener-based references interface with high-speed circuitry.
