Product details
Overview
BZX8850-C3V6YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 3.6 V nominal with ±2 % tolerance, 2.0 µA reverse current at 1 V, 95 Ω differential resistance at 5 mA, and 250 mW total power dissipation - used in battery-powered sensor biasing and low-power reference circuits.
For engineers reviewing the BZX8850-C3V6YL datasheet, BZX8850-C3V6YL pinout, BZX8850-C3V6YL application, or BZX8850-C3V6YL equivalent, this page delivers verified electrical characteristics, thermal limits, SOD882 footprint details, and direct substitution guidance for low-current Zener regulation in space-constrained portable designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 50 µA, enabling stable regulation under ultra-low bias conditions typical of IoT sensor nodes and wearable device power rails. Its 3.6 V nominal Zener voltage exhibits a temperature coefficient of −3.5 mV/K and 160 pF capacitance at 0 V, supporting noise-sensitive analog references.
The device uses silicon planar epitaxial construction with cathode-anode polarity defined by a top-side marking bar, and achieves thermal resistance of 500 K/W when mounted on standard FR4 PCB - critical for thermal management in unheatsinked compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.42 V to 3.78 V at IZ = 50 µA - ensures tight 3.6 V regulation across production lots for accurate low-power reference generation |
| Differential Resistance (rdiff) | 95 Ω at IZ = 5 mA - maintains voltage stability against small load current variations in precision bias networks |
| Reverse Current (IR) | 2.0 µA at VR = 1 V - enables ultra-low quiescent current operation essential for multi-year battery life in remote sensors |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - defines forward conduction threshold for protection or clamping use cases |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB without derating |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation in sealed enclosures |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - supports 0201-class board area efficiency for high-density portable PCBs |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package with two terminals and a cathode-marking bar on the top surface. The body measures 1.0 mm × 0.6 mm × 0.5 mm and requires reflow-compatible solder land pattern per Figure 10 in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar for automated optical inspection |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current specification | Rated at 50 µA - enables stable regulation in microamp-level bias circuits where traditional Zeners fail to activate |
| Tight voltage tolerance | ±2 % for C-series - reduces need for post-production trimming in factory-calibrated sensor modules |
| Ultra-small footprint | DFN1006-2 (0.6 mm width) - saves >40 % board area versus SOD-123 while maintaining solder joint reliability |
| Optimized leakage profile | Intentional minor rise in leakage for BZX8850-C variants - improves switching speed and reduces noise in dynamic reference applications |
| Thermal performance | 500 K/W Rth(j-a) on FR4 - allows direct thermal modeling without heatsinking in ambient-temperature-limited designs |

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C3V6YL?
The device is rated for Zener breakdown at 3.42 V to 3.78 V when tested at 50 µA. Below 3.42 V, reverse current remains ≤2.0 µA at 1 V; sustained reverse voltage above 3.78 V risks exceeding the 250 mW power limit unless current is strictly limited by external series resistance.
Can BZX8850-C3V6YL be used in forward conduction mode?
Yes - its forward voltage is 0.9 V at 10 mA, matching standard silicon diode behavior. However, it is not optimized for rectification; forward operation is typically limited to ESD protection or polarity protection where low VF is secondary to Zener regulation performance.
How does the "C" suffix differ from "B" in the BZX8850 series?
The "C" suffix denotes ±2 % Zener voltage tolerance and an intentional minor rise in leakage current to improve switching speed and reduce noise, per Application Note AN90031. "B" parts offer ±5 % tolerance and lower leakage but slower transient response.
Is BZX8850-C3V6YL suitable for automotive applications?
No - this part is not AEC-Q200 qualified. Nexperia explicitly states non-automotive qualification in the legal disclaimers. For automotive use, select Nexperia's AEC-Q200-qualified PZM series or equivalent qualified Zeners with documented PPAP support.
