Product details
Overview
BZX8850-C9V1YL 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, features 100 Ω differential resistance at 5 mA, and operates with ≤250 mW total power dissipation. Used in portable battery-powered circuits requiring low-bias, low-leakage voltage stabilization.
For engineers reviewing the BZX8850-C9V1YL datasheet, BZX8850-C9V1YL pinout, BZX8850-C9V1YL application, or BZX8850-C9V1YL equivalent, this page provides verified electrical parameters, thermal behavior, package dimensions, cathode/anode terminal mapping, and validated alternative Zeners for low-power regulation design.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 9.1 V reference under low-current conditions (IZ = 50 µA to 5 mA), with temperature coefficient of +3.8 mV/K and junction-to-ambient thermal resistance of 500 K/W on FR4 PCB. Its ultra-small DFN1006-2 footprint enables high-density layout in space-constrained portable electronics.
The device exhibits 0.1 µA reverse leakage at VR = 7.0 V, 6.9 V Zener knee voltage at 50 µA, and 150 pF capacitance at 0 V bias - characteristics optimized for noise-sensitive analog references and fast-switching regulator feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, ±2 % tolerance (8.65–9.56 V), specified at IZ = 50 µA for low-bias stability |
| Differential Resistance (rdiff) | 100 Ω max at IZ = 5 mA - ensures minimal voltage shift under load variation |
| Reverse Leakage (IR) | 0.1 µA max at VR = 7.0 V - supports ultra-low quiescent current designs |
| Power Dissipation (Ptot) | 250 mW max at Tamb ≤ 25 °C on standard FR4 PCB - defines thermal derating envelope |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables predictable forward conduction during transient clamping |
| Temperature Coefficient (SZ) | +3.8 mV/K - quantifies VZ drift per degree Celsius for ambient-compensated reference design |
| Junction Temperature (Tj) | 150 °C max - sets absolute upper limit for safe operation under sustained power stress |
Pinout & Package
SOD882 (DFN1006-2) leadless ultra-small plastic package: 1.0 mm × 0.6 mm × 0.5 mm body, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for reference generation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables use in microamp-level battery monitoring and sensor biasing |
| Tight voltage tolerance | ±2 % (B-series) - reduces need for post-regulation trimming in precision analog circuits |
| Ultra-compact packaging | DFN1006-2 footprint - saves >70 % board area vs. traditional DO-35 or SOD-123 packages |
| Optimized leakage profile | Intentional minor IR rise (per AN90031) - improves switching speed and reduces broadband noise in feedback loops |
| Thermal performance | Rth(j-a) = 500 K/W on single-sided FR4 - allows accurate thermal modeling without heatsinking |
Applications
| Portable Battery Monitoring | Low-Power Sensor Biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1 | Same 9.1 V, ±5 % tolerance; SOT-23 package; 350 mW Ptot; higher rdiff (150 Ω) | Higher power handling but larger footprint; less suitable for ultra-dense layouts | Select when board space permits and higher surge immunity is required |
| MMSZ5240B | 9.1 V, ±5 %; SOD-123 package; 500 mW Ptot; rdiff = 150 Ω; TC = +4.5 mV/K | Higher power rating and thermal mass; less stable TC for precision references | Choose for industrial environments with wider ambient swings and no size constraint |
Compared with BZX8850-C9V1YL, BZX84-C9V1 offers greater power margin but sacrifices accuracy and miniaturization, while MMSZ5240B trades tighter TC control for robustness-making the C9V1YL optimal for space- and current-constrained portable regulation.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C9V1YL?
The device is rated for Zener breakdown at 9.1 V nominal with ±2 % tolerance (8.65–9.56 V), tested at 50 µA. It does not specify a distinct "breakdown threshold" - instead, the knee voltage is defined as 6.9 V at 50 µA, rising to full regulation within the tolerance band at higher currents. Absolute maximum reverse voltage is limited by Ptot and thermal constraints, not a hard clamp.
Can BZX8850-C9V1YL be used in forward conduction mode?
Yes - it functions as a standard silicon diode in forward bias, with VF ≤ 0.9 V at 10 mA. This enables dual-use in circuits requiring both reverse-bias regulation and forward-bias clamping or polarity protection, though its primary design intent remains Zener reference operation.
How does the SOD882 package affect thermal performance compared to SOD-123?
The SOD882 (DFN1006-2) has higher thermal resistance: Rth(j-a) = 500 K/W vs. ~300 K/W for SOD-123 on identical FR4 PCB. This requires stricter power derating above 25 °C ambient - e.g., Ptot drops to ~125 mW at 75 °C - but enables 60 % smaller board area and improved high-frequency response due to lower parasitic inductance.
Is BZX8850-C9V1YL suitable for automotive applications?
No - this part is not AEC-Q200 qualified, lacks automotive-grade screening, and is explicitly designated for industrial and consumer portable applications. Nexperia's datasheet states non-automotive qualification applies unless otherwise specified; use only in non-safety-critical, non-life-support systems.
