Product details
Overview
BZX8850-B10YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 10 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 μA test current, features 250 mW total power dissipation, and exhibits 7.6 V reverse breakdown voltage at 5 mA, supporting battery-powered sensor biasing and low-power analog signal conditioning.
For engineers reviewing the BZX8850-B10YL datasheet, BZX8850-B10YL pinout, BZX8850-B10YL application, or BZX8850-B10YL equivalent, this device is selected for ultra-small footprint voltage clamping, low-leakage reference generation, and portable system rail stabilization where thermal budget and board space are constrained.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a specified nominal Zener voltage of 10.0 V at IZ = 50 μA, maintaining tight ±2 % tolerance across temperature. Its differential resistance is ≤150 Ω at IZ = 5 mA, ensuring minimal voltage shift under load variation.
The device uses silicon planar technology with cathode-anode terminal configuration, optimized for low leakage (≤0.1 μA at VR = 7.6 V), and exhibits a positive temperature coefficient of +4.5 mV/K - enabling predictable drift compensation in reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.80 V to 10.20 V at IZ = 50 μA - defines precise regulation point for low-bias reference design |
| Tolerance | ±2 % - enables high-accuracy voltage clamping without external trimming |
| Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - supports operation on standard FR4 PCB without heatsinking |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - ensures minimal conduction loss when used in bidirectional protection |
| Differential Resistance rdiff | ≤150 Ω at IZ = 5 mA - limits output impedance for stable regulation under varying load |
| Reverse Leakage IR | ≤0.1 μA at VR = 7.6 V - critical for ultra-low-power standby and battery-life-critical circuits |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - enables <1 mm² board area usage in space-constrained wearables and IoT nodes |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package with two terminals and a transparent top view. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive connection for reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | DFN1006-2 package occupies only 0.6 mm² PCB area - ideal for miniaturized sensor modules and hearing aids |
| Low test current operation | Specified at 50 μA - enables direct use with high-impedance op-amp inputs and microamp-level bias networks |
| Controlled leakage profile | Intentional minor leakage rise per AN90031 - improves switching speed and reduces noise in transient suppression |
| Thermal stability | +4.5 mV/K temperature coefficient - allows predictable drift modeling for compensated reference designs |
| Robust surge rating | 40 W non-repetitive peak reverse power (tp = 100 μs) - withstands ESD transients per IEC 61000-4-2 Level 4 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-C10 | ±5 % tolerance, higher leakage (0.1 μA vs. B-series), same 10 V nominal | Acceptable for non-critical biasing where cost sensitivity outweighs accuracy | Select for cost-driven consumer electronics where ±5 % regulation suffices |
| MMSZ4689 | Same 10 V nominal but ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 500 mW rating | Requires 4.3× more PCB area; suited for higher-power industrial regulators | Choose when higher power margin (500 mW) and legacy SMT compatibility are required |
Compared with BZX8850-C10 and MMSZ4689, the BZX8850-B10YL provides superior accuracy (±2 %) and smallest footprint (0.6 mm²), making it optimal for space- and precision-constrained portable designs - whereas C10 trades accuracy for cost, and MMSZ4689 trades size for power headroom.

FAQ
What is the maximum continuous power dissipation for BZX8850-B10YL?
The BZX8850-B10YL 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. Derating is required above 25 °C at 2.5 mW/°C, based on its 500 K/W junction-to-ambient thermal resistance.
Can BZX8850-B10YL be used in place of a 10 V Zener with ±5 % tolerance?
Yes, but only where tighter regulation is beneficial. The BZX8850-B10YL offers ±2 % tolerance versus ±5 % for C-series parts, reducing worst-case output variation from ±0.5 V to ±0.2 V at 10 V - critical for precision analog stages but not required for basic clamping.
How does the cathode marking appear on the SOD882 package?
The cathode is indicated by a visible bar on the top surface of the DFN1006-2 package. In the transparent top view shown in the datasheet, Pin 1 (cathode) is located at the left edge, adjacent to the marking bar, while Pin 2 (anode) is at the right edge.
Is BZX8850-B10YL suitable for automotive applications?
No. The BZX8850-B10YL is not AEC-Q200 qualified and lacks automotive-grade screening, temperature range validation (−40 °C to +125 °C), or failure rate data required for automotive use. It is rated for −55 °C to +150 °C ambient but intended for industrial and consumer applications only.
