Product details
Overview
BZX8850-B9V1YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 9.1 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 μA test current, exhibits 6.9 V Zener knee voltage, 150 Ω differential resistance at 5 mA, and 3.8 mV/K temperature coefficient - enabling use in battery-powered sensor biasing and low-power analog signal conditioning.
For engineers reviewing the BZX8850-B9V1YL datasheet, BZX8850-B9V1YL pinout, BZX8850-B9V1YL application, or BZX8850-B9V1YL equivalent, key selection criteria include its ultra-low 50 μA regulation current, 250 mW power rating on FR4 PCB, 150 °C max junction temperature, and cathode-marked DFN1006-2 footprint compatibility with high-density portable designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 9.1 V reference under low-bias conditions. Its specified 50 μA test current enables operation in microampere-level circuits where traditional Zeners draw excessive quiescent current.
The device features a 150 Ω dynamic impedance at 5 mA, a +3.8 mV/K positive temperature coefficient, and 7.0 pF capacitance at 0 V - supporting stable DC reference generation without introducing significant AC loading in precision analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, ±2 % tolerance - ensures tight reference accuracy for low-power voltage monitoring |
| Test Current (IZ) | 50 μA - enables regulation in battery-critical applications where standby current must be minimized |
| Differential Resistance (rdiff) | 150 Ω at IZ = 5 mA - defines output impedance stability under small-signal load variations |
| Temperature Coefficient (SZ) | +3.8 mV/K - quantifies drift rate over temperature, critical for thermal compensation design |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - supports bidirectional clamping or dual-use as forward diode in protection circuits |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - defines operational envelope for industrial and extended-temperature environments |
Pinout & Package
Package: SOD882 (DFN1006-2), leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm; cathode indicated by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker determines correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low Test Current Operation | Specified at 50 μA - reduces quiescent power in always-on sensor nodes and IoT edge devices |
| Tight Voltage Tolerance | ±2 % (B-series) - eliminates need for post-production trimming in precision reference circuits |
| Ultra-Small Footprint | SOD882 (1.0 × 0.6 mm) - saves board space in wearables, hearing aids, and compact medical sensors |
| Optimized Leakage Profile | Intentional minor leakage rise per AN90031 - improves switching speed and reduces noise in dynamic bias networks |
| Thermal Robustness | 150 °C max junction temperature - supports reliable operation in sealed enclosures without active cooling |
Applications
| Portable Sensor Biasing | Low-Power ADC Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-C9V1 | ±5 % tolerance, higher leakage (0.1 μA vs. B-series' unspecified but lower), same 9.1 V nominal | Acceptable where cost sensitivity outweighs precision; less suitable for metrology-grade references | Select when budget constraints dominate and ±5 % regulation accuracy suffices for non-critical biasing |
| MMSZ5240B | Same 10 V nominal (not 9.1 V), SOD-123 package (2.7 × 1.6 mm), 500 mW rating, ±5 % tolerance | Larger footprint and higher power dissipation - unsuitable for space-constrained portable designs | Choose only if board layout allows larger package and 10 V (not 9.1 V) reference is acceptable |
Compared with BZX8850-C9V1 and MMSZ5240B, the BZX8850-B9V1YL uniquely combines ±2 % tolerance, 50 μA test current, and 1.0 × 0.6 mm DFN footprint - making it the sole option for high-accuracy, ultra-compact, low-quiescent regulation in next-generation portable electronics.

FAQ
What is the maximum continuous reverse power dissipation for BZX8850-B9V1YL?
The BZX8850-B9V1YL has a total power dissipation limit of 250 mW at ambient temperature ≤25 °C when mounted on a standard FR4 PCB with single-sided copper. This rating decreases with rising ambient temperature due to thermal resistance of 500 K/W from junction to ambient.
Does BZX8850-B9V1YL support bidirectional ESD protection?
No - BZX8850-B9V1YL is a unidirectional Zener diode optimized for reverse-bias voltage regulation. Its forward voltage is ≤0.9 V at 10 mA, but it lacks symmetric clamping characteristics or specified ESD ratings required for dedicated bidirectional protection.
How does the 50 μA test current impact circuit design?
The 50 μA test current means the diode achieves its specified 9.1 V Zener voltage with only 50 μA flowing through it - enabling use in ultra-low-power circuits such as coin-cell-powered RTCs or energy-harvesting sensors where traditional 5 mA Zeners would drain the source excessively.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - the SOD882 (DFN1006-2) package is qualified for lead-free reflow soldering. Nexperia provides a recommended footprint (Fig. 10) with 0.3 mm solder paste pads and 0.9 mm overall length, compatible with IPC-7095 guidelines for ultra-small passive components.
