Product details
Overview
BZX8850-C2V7YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 2.7 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, features 600 Ω differential resistance at 50 µA, and operates within −55 °C to +150 °C ambient range-ideal for battery-powered sensor nodes and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-C2V7YL datasheet, BZX8850-C2V7YL pinout, BZX8850-C2V7YL application, or BZX8850-C2V7YL equivalent, this page provides verified electrical characteristics, thermal behavior, SOD882 footprint compatibility, and direct replacement guidance for low-bias voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 2.7 V at IZ = 50 µA, exhibiting a temperature coefficient of −3.5 mV/K and typical capacitance of 190 pF at 0 V. Its low test current enables minimal quiescent power draw in always-on monitoring circuits.
The device uses silicon planar technology with intentional minor leakage optimization per AN90031, supporting fast transient response and reduced noise in analog front-end biasing. Thermal resistance from junction-to-ambient is 500 K/W on FR4 PCB with single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.565 V to 2.835 V at IZ = 50 µA - tight ±2 % tolerance ensures accurate low-voltage reference without trimming. |
| Differential Resistance rdiff | 600 Ω max at IZ = 50 µA - defines regulation stiffness under light-load variations in portable systems. |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables use as low-drop clamp or polarity protection in dual-role layouts. |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - supports continuous operation in space-constrained SMD designs with minimal heatsinking. |
| Reverse Current IR | ≤ 1 µA at VR = 1 V - ensures negligible standby current drain in battery-critical applications. |
| Junction Temperature Tj | −55 °C to +150 °C - validated for industrial and extended-temperature embedded control environments. |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - ultra-small footprint compatible with high-density PCB routing and reflow assembly. |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package with exposed copper thermal pad not connected internally; 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 at VZ. |

Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - reduces system standby current by >90 % versus standard 5 mA Zeners. |
| Tight voltage tolerance | ±2 % (C-series) - eliminates need for external trimming in 2.7 V reference rails for ADCs and comparators. |
| Optimized leakage profile | Intentional minor rise per AN90031 - improves switching speed and reduces broadband noise in feedback paths. |
| Ultra-compact packaging | SOD882 footprint (1.0 × 0.6 mm) - saves >70 % board area vs. SOD-123 and enables 0201-class layout density. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5223BS-7-F | 2.7 V ±5 %, SOT-323 package, 200 mW rating, rdiff = 100 Ω @ 20 mA | Higher test current (20 mA) increases standby power; larger SOT-323 footprint occupies 3× board area | Select when higher power handling or legacy footprint compatibility is required over ultra-low IQ. |
| BZX384-C2V7 | 2.7 V ±2 %, SOD-323 package, 300 mW rating, rdiff = 120 Ω @ 5 mA | Requires 5 mA test current - 100× higher than BZX8850-C2V7YL - unsuitable for sub-µA standby systems | Choose only if thermal margin >300 mW is mandatory and board space allows SOD-323 (1.7 × 1.25 mm). |
Compared with MMBZ5223BS-7-F and BZX384-C2V7, the BZX8850-C2V7YL uniquely combines ±2 % tolerance, 50 µA test current, and DFN1006-2 size-making it the sole option for space- and current-constrained 2.7 V reference designs requiring <1 µA quiescent contribution.

FAQ
What is the maximum reverse voltage the BZX8850-C2V7YL can withstand before breakdown?
The BZX8850-C2V7YL has a nominal Zener voltage of 2.7 V, with guaranteed breakdown occurring between 2.565 V and 2.835 V at 50 µA test current. Its absolute maximum non-repetitive peak reverse voltage is defined by the 40 W surge rating at 100 µs pulse width-not a DC rating-and must be applied with appropriate series limiting resistance to avoid exceeding 250 mW steady-state dissipation.
Does the SOD882 package require special soldering profiles?
Yes-the DFN1006-2 (SOD882) package requires precise reflow profiling per Nexperia's Fig. 10 footprint: peak temperature ≤ 260 °C, time above 217 °C limited to 60–90 seconds, and ramp rates controlled to prevent tombstoning. The cathode-marked side must face upward, and solder paste volume must match the 0.3 mm × 0.9 mm land pattern to ensure void-free thermal pad wetting.
How does the −3.5 mV/K temperature coefficient affect circuit performance?
A −3.5 mV/K coefficient means the Zener voltage decreases by 3.5 mV per degree Celsius rise in junction temperature. Over a 100 °C range (−40 °C to +60 °C), this introduces up to ±350 mV drift-however, in low-power applications where self-heating is minimal (<5 °C rise), actual variation remains within ±17.5 mV, preserving accuracy for most non-precision references.
Can BZX8850-C2V7YL replace BZX84-C2V7 in existing designs?
No-BZX84-C2V7 uses SOT-23 package (3.0 × 1.4 mm) with different pinout (cathode on pin 3), 350 mW rating, and 5 mA test current. Direct substitution would cause board-level fit issues, excessive standby current, and potential thermal mismatch. A redesign using the SOD882 footprint and updated bias network is required for migration.
