Product details
Overview
BZX8850-C3V3YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 3.3 V nominal with ±2 % tolerance, 50 µA test current, and 250 mW power dissipation-used in battery-powered sensor biasing, reference voltage generation, and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-C3V3YL datasheet, BZX8850-C3V3YL pinout, BZX8850-C3V3YL application, or BZX8850-C3V3YL equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance data critical for low-bias analog design and portable power management validation.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 3.3 V at IZ = 50 µA, exhibiting a typical differential resistance of 600 Ω at that current and 100 Ω at 1 mA-enabling stable regulation under light-load conditions. Its temperature coefficient is −3.5 mV/K, indicating predictable negative drift over temperature.
The device features intentional minor leakage current optimization per AN90031 for fast switching and reduced noise, and is rated for 150 °C junction temperature with 500 K/W junction-to-ambient thermal resistance on FR4 PCB-supporting compact, thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.13 V to 3.47 V at IZ = 50 µA - tight ±2 % tolerance enables accurate 3.3 V rail referencing without trimming. |
| Differential Resistance rdiff | 600 Ω at IZ = 50 µA; 100 Ω at IZ = 1 mA - low dynamic impedance ensures minimal output voltage shift under varying load current. |
| Temperature Coefficient SZ | −3.5 mV/K - predictable negative drift allows compensation in temperature-sensitive references. |
| Reverse Current IR | ≤ 0.8 µA at VR = 3.0 V - ultra-low leakage preserves battery life in always-on monitoring circuits. |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - supports use as clamp or protection diode in bidirectional signal paths. |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sufficient for low-duty-cycle regulation in space-constrained SMD designs. |
| Junction-to-Ambient Rth(j-a) | 500 K/W on single-sided FR4 - defines thermal derating curve for continuous operation above ambient. |
Pinout & Package
Package: SOD882 (DFN1006-2), leadless ultra-small surface-mount plastic package; dimensions 1.0 × 0.6 × 0.5 mm; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed for correct Zener conduction in reverse bias. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; forms current path during breakdown regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables regulation in µA-level bias networks for IoT sensor nodes and sleep-mode circuits. |
| Tight voltage tolerance | ±2 % (C-series) - eliminates need for external trimming in 3.3 V reference applications like ADC voltage references. |
| Optimized leakage profile | Intentional minor IR rise per AN90031 - reduces switching noise in timing and clock conditioning circuits. |
| Ultra-compact footprint | DFN1006-2 (1.0 × 0.6 mm) - supports high-density PCB layouts in wearables and miniature medical devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3 | SC-70 package (2.2 × 1.35 mm); 350 mW Ptot; ±5 % tolerance; rdiff = 90 Ω @ 5 mA | Higher power handling but larger footprint; less precise voltage control | Select when board space permits and tighter tolerance is not required. |
| MMSZ5226B | SOD-123 package (3.7 × 1.6 mm); 500 mW Ptot; ±5 % tolerance; VZ = 3.3 V @ 20 mA | Higher test current and power rating; unsuitable for µA-level biasing | Choose only for higher-current regulation where thermal margin is critical. |
Compared with BZX8850-C3V3YL, BZX84-C3V3 offers higher power but looser tolerance and larger size, while MMSZ5226B trades miniaturization for robustness at higher currents-making the BZX8850-C3V3YL optimal for space- and current-constrained 3.3 V reference designs.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C3V3YL?
The nominal Zener voltage is 3.3 V, with guaranteed range of 3.13 V to 3.47 V at 50 µA test current. Breakdown begins within this band; operation below 3.13 V ensures non-conducting state. Absolute maximum reverse voltage is not defined-only the Zener region is specified.
Can BZX8850-C3V3YL be used in forward-biased protection applications?
Yes: its forward voltage is ≤ 0.9 V at 10 mA, making it suitable for low-threshold clamping in signal lines. However, it is not optimized for high-current surge suppression-the 200 mA absolute max forward current limits duty cycle in repetitive transient scenarios.
How does the −3.5 mV/K temperature coefficient affect circuit performance?
A −3.5 mV/K coefficient means VZ decreases by ~0.35 V over a 100 °C range (e.g., −40 °C to +60 °C). In precision references, this drift must be compensated via resistor networks or calibration-especially critical in wide-temperature industrial sensors.
Is BZX8850-C3V3YL suitable for automotive applications?
No: this part is not AEC-Q200 qualified, lacks automotive-grade screening, and is not rated for extended temperature operation beyond −55 °C to +150 °C ambient. Nexperia explicitly states non-automotive qualification in the legal disclaimers-use only in consumer, industrial, or medical portable equipment.
