Product details
Overview
BZX8850-C2V2YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 2.2 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 μA test current, features 600 Ω differential resistance at IZ = 50 μA, −3.5 mV/K temperature coefficient, and 210 pF capacitance at 1 MHz - ideal for battery-powered sensor biasing and low-power analog signal conditioning.
For engineers reviewing the BZX8850-C2V2YL datasheet, BZX8850-C2V2YL pinout, BZX8850-C2V2YL application, or BZX8850-C2V2YL equivalent, this device serves as a compact, low-leakage voltage reference for portable instrumentation, wearables, and IoT node power management where minimal quiescent current and tight voltage accuracy are critical.
Technical Context
This Zener operates in reverse breakdown mode with a nominal 2.2 V regulation voltage, specified at IZ = 50 μA to ensure ultra-low standby current draw. Its −3.5 mV/K temperature coefficient minimizes drift across −55 °C to +150 °C ambient range, supporting stable reference generation in thermally variable environments.
The device exhibits 600 Ω dynamic impedance at 50 μA and drops to 100 Ω at 1 mA, enabling predictable regulation under light load shifts. Its 210 pF junction capacitance at 0 V bias supports high-frequency noise filtering in mixed-signal supply rails without compromising stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 2.2 V ±2 % at IZ = 50 μA - ensures precise low-current reference for sensor excitation and ADC biasing |
| Differential Resistance | 600 Ω at IZ = 50 μA - maintains regulation accuracy under microamp-level load variations |
| Temperature Coefficient | −3.5 mV/K - limits voltage drift to ±44 mV over −40 °C to +85 °C operating range |
| Junction Capacitance | 210 pF at f = 1 MHz, VR = 0 V - suppresses RF noise on low-voltage analog supply lines |
| Forward Voltage | 0.9 V at IF = 10 mA - enables reliable anode-cathode polarity verification during board test |
| Total Power Dissipation | 250 mW at Tamb ≤ 25 °C on FR4 PCB - supports continuous operation in space-constrained SMT layouts |
| Reverse Leakage Current | 1.0 μA max at VR = 1 V - guarantees negligible current draw in always-on battery backup circuits |

Package: SOD882 (DFN1006-2), leadless ultra-small 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; marking bar identifies this terminal for correct orientation during placement |
| 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 use in nanoamp-level standby circuits without regulation collapse |
| Tight voltage tolerance | ±2 % (C-series) - eliminates need for post-production trimming in precision reference designs |
| Ultra-small footprint | DFN1006-2 (1.0 × 0.6 mm) - saves >70 % board area vs. traditional SOD-123 Zeners |
| Optimized leakage profile | Intentional minor leakage rise per AN90031 - improves switching speed and reduces broadband noise in feedback paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-B2V2 | ±5 % tolerance, higher rdiff (600 Ω at 50 μA same, but 100 Ω only at 1 mA vs. C-series' 100 Ω at 1 mA), identical thermal specs | Acceptable where cost sensitivity outweighs precision; less suitable for <12-bit measurement systems | Select for non-critical biasing where ±5 % regulation suffices and BOM cost reduction is prioritized |
| MMSZ5222B | Same 2.2 V nominal, ±5 % tolerance, SOD-123 package (2.7 × 1.7 mm), 500 mW Ptot, 22 Ω rdiff at 20 mA - not rated at 50 μA | Requires higher bias current; incompatible with nanoamp standby modes; larger footprint limits high-density layouts | Choose only if existing design uses SOD-123 footprint and system can support ≥1 mA Zener current |
Compared with BZX8850-B2V2 and MMSZ5222B, the BZX8850-C2V2YL uniquely combines ±2 % tolerance, DFN1006-2 miniaturization, and 50 μA test current rating - making it the sole option for space-constrained, battery-life-critical applications demanding sub-0.5 % reference accuracy without active regulation.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C2V2YL?
The BZX8850-C2V2YL has a nominal Zener voltage of 2.2 V with ±2 % tolerance, meaning breakdown occurs between 2.156 V and 2.244 V at IZ = 50 μA. Its absolute maximum non-repetitive peak reverse voltage is not specified independently; instead, it is governed by the 40 W non-repetitive surge rating at tp = 100 μs, corresponding to ~200 V transient for that pulse width.
Can BZX8850-C2V2YL be used in series for higher reference voltages?
No - the BZX8850-C2V2YL is not characterized or guaranteed for series operation. Its low 50 μA test current and high dynamic impedance at microamp currents cause unpredictable voltage division and thermal imbalance. For higher references, use single-device Zeners rated for the target voltage or dedicated reference ICs.
Is the cathode marking visible under standard optical inspection?
Yes - the cathode is indicated by a laser-marked bar on the top surface of the DFN1006-2 package, fully visible under 20× magnification and compatible with automated optical inspection (AOI) systems using standard white-light illumination and contrast settings.
Does BZX8850-C2V2YL meet RoHS and REACH requirements?
Yes - BZX8850-C2V2YL is manufactured by Nexperia in compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with full substance declarations available in Nexperia's official material compliance reports dated July 2024.
