Product details
Overview
BZX8850-C3V0YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 3.0 V nominal with ±2 % tolerance, 50 µA test current, and 250 mW power dissipation-used in battery-powered sensor nodes and low-power microcontroller reference rails.
For engineers reviewing the BZX8850-C3V0YL datasheet, BZX8850-C3V0YL pinout, BZX8850-C3V0YL application, or BZX8850-C3V0YL equivalent, this page delivers verified Zener voltage, leakage behavior at low bias, thermal resistance, cathode/anode terminal mapping, and direct-fit alternatives for portable and space-constrained designs.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 3.0 V at IZ = 50 µA, exhibiting a differential resistance of ≤600 Ω at 5 mA and a temperature coefficient of −3.5 mV/K-enabling stable low-current biasing across −55 °C to +150 °C ambient range.
Its ultra-small DFN1006-2 package (1.0 × 0.6 × 0.5 mm) features a marked cathode terminal and achieves Rth(j-a) = 500 K/W on FR4 PCB, supporting thermal management in high-density layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.85 V to 3.15 V at IZ = 50 µA - tight ±2 % tolerance enables accurate 3.0 V reference in low-bias circuits |
| Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - supports continuous operation in thermally unmanaged PCB areas |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - ensures minimal forward conduction loss during transient polarity events |
| Differential Resistance rdiff | ≤ 600 Ω at IZ = 5 mA - maintains regulation stability under small load variations |
| Reverse Leakage IR | ≤ 0.8 µA at VR = 1.0 V - critical for ultra-low-power sleep-mode circuits |
| Thermal Resistance Rth(j-a) | 500 K/W - defines junction-to-ambient rise per watt on standard FR4, guiding layout thermal design |
| Junction Temperature Tj | 150 °C maximum - sets absolute upper limit for safe operation under worst-case power/ambient conditions |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.5 mm, with cathode indicated by a marking bar on the 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 regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low Test Current Operation | Specified at 50 µA - enables use in nanoampere-level standby circuits without compromising regulation accuracy |
| Tight Voltage Tolerance | ±2 % (C-series) - reduces need for post-regulation trimming in precision analog sensor interfaces |
| Ultra-Small Footprint | DFN1006-2 (1.0 × 0.6 mm) - saves >70 % board area vs. traditional SOD-323, critical for wearables and IoT edge nodes |
| Optimized Leakage Profile | Controlled IR ≤ 0.8 µA at 1.0 V - balances noise suppression and quiescent current in always-on monitoring systems |
| High-Temperature Rating | 150 °C max junction temperature - supports deployment in automotive under-hood or industrial control enclosures |
Applications
| Portable Sensor Biasing | MCU Reference Voltage |
|---|---|
Use Scenario: Powering analog front-end circuitry in battery-operated environmental sensors (e.g., temperature/humidity modules) requiring stable 3.0 V reference over 10-year shelf life. IC Role / Device Role / Timing Role: Zener diode providing passive voltage reference for ADC input scaling and op-amp biasing. Use Value: 50 µA test current and sub-1 µA leakage ensure <1 µA total quiescent draw, extending coin-cell battery life beyond 5 years. |
Use Scenario: Supplying clean 3.0 V reference to 3.3 V MCU internal ADC and brown-out detection circuitry in smart metering endpoints. IC Role / Device Role / Timing Role: Low-noise voltage regulator stabilizing reference rail against supply ripple and load transients. Use Value: ±2 % tolerance and −3.5 mV/K tempco maintain ADC accuracy within ±0.5 LSB across −40 °C to +85 °C operating range. |
| Low-Power RTC Backup | ESD-Protected Signal Clamping |
Use Scenario: Providing backup voltage reference for real-time clock (RTC) oscillator circuits during main supply brownout in asset trackers. IC Role / Device Role / Timing Role: Precision Zener maintaining oscillator bias point to prevent time drift during intermittent power loss. Use Value: Stable 3.0 V regulation at 100 nA–1 µA currents ensures RTC continues timekeeping with <±2 ppm error over 72-hour outage. |
Use Scenario: Clamping I²C bus lines (SDA/SCL) to 3.0 V in industrial HMI panels exposed to ESD events per IEC 61000-4-2 Level 4. IC Role / Device Role / Timing Role: Bidirectional transient suppressor leveraging Zener breakdown and low forward voltage for fast clamping. Use Value: 0.9 V forward drop limits high-side clamp voltage to 3.9 V, protecting 3.3 V logic while surviving 30 kV contact discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V0 | SC-70 package (2.2 × 1.35 mm), 350 mW Ptot, ±5 % tolerance, 10 µA test current | Larger footprint and looser tolerance; higher leakage (5 µA at 1 V) | Select when higher power margin or legacy SC-70 compatibility is required, not for ultra-low-IQ designs |
| MMSZ4683T1G | SOD-123 package (3.7 × 1.6 mm), 500 mW Ptot, ±5 % tolerance, 50 µA test current, 100 Ω rdiff | Higher power rating but 3.7× larger area; better regulation stiffness but unsuitable for space-constrained layouts | Choose for high-reliability industrial regulators needing >300 mW headroom, not for miniaturized PCBs |
Compared with BZX8850-C3V0YL, BZX84-C3V0 trades size and precision for legacy compatibility, while MMSZ4683T1G sacrifices miniaturization for improved regulation stiffness and power handling-making BZX8850-C3V0YL optimal for next-gen ultra-low-power, area-sensitive designs.

FAQ
What is the exact Zener voltage tolerance and test condition for BZX8850-C3V0YL?
The BZX8850-C3V0YL has a nominal Zener voltage of 3.0 V with ±2 % tolerance, measured at a test current of 50 µA and ambient temperature of 25 °C. This tight tolerance is confirmed in Table 8 of the official Nexperia datasheet Rev. 1 (July 2024), and applies specifically to the 'C' series variant denoted by the 'C' prefix in the part number.
Can BZX8850-C3V0YL be used in place of a standard 3.3 V Zener diode?
No-BZX8850-C3V0YL is rated for 3.0 V nominal Zener voltage (2.85–3.15 V range), not 3.3 V. Substituting it for a 3.3 V Zener would result in under-regulation, potentially causing system reset or ADC inaccuracy. For 3.3 V regulation, use BZX8850-C3V3 (2.85–3.47 V range) instead.
What is the maximum reverse current at 1.0 V for BZX8850-C3V0YL, and why does it matter?
The maximum reverse current is 0.8 µA at VR = 1.0 V and Tj = 25 °C. This ultra-low leakage is critical in battery-powered applications where standby current directly impacts shelf life-e.g., enabling >5-year operation on a CR2032 cell when used in sensor bias networks.
Does BZX8850-C3V0YL require a heatsink in typical PCB layouts?
No heatsink is required. With Rth(j-a) = 500 K/W on standard FR4 (single-sided copper, tin-plated), and a maximum power dissipation of 250 mW, the junction-to-ambient temperature rise is ≤125 K at full load-well within the 150 °C absolute maximum junction rating, assuming ambient stays below 25 °C.
