Product details
Overview
BZX8850-B15YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 15 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 μA test current, features 200 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range-ideal for battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the BZX8850-B15YL datasheet, BZX8850-B15YL pinout, BZX8850-B15YL application, or BZX8850-B15YL equivalent, this page provides verified electrical parameters, thermal behavior, SOD882 terminal mapping, and direct-fit alternatives for low-power voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 15 V at IZ = 50 μA, exhibiting a temperature coefficient of +9.2 mV/K and differential resistance of 200 Ω at 5 mA. Its low leakage (<0.05 μA at VR = 12 V) supports high-impedance bias networks.
The device uses silicon planar technology in an ultra-small leadless DFN1006-2 package with cathode-marked top-side orientation. Thermal resistance from junction to ambient is 500 K/W on FR4 PCB, limiting continuous power dissipation to 250 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 14.7 V to 15.3 V at IZ = 50 μA - tight ±2 % tolerance enables accurate low-current reference without trimming |
| Differential resistance rdiff | 200 Ω max at IZ = 5 mA - ensures minimal output voltage shift under small load variations |
| Forward voltage VF | 0.9 V max at IF = 10 mA - low conduction loss when used bidirectionally or in protection circuits |
| Total power dissipation Ptot | 250 mW max at Tamb ≤ 25 °C - defines safe DC operating envelope on standard FR4 PCB |
| Junction temperature Tj | 150 °C max - sets upper thermal limit for reliability in compact, unventilated enclosures |
| Reverse current IR | <0.05 μA at VR = 12 V - enables use in nanoampere-bias analog front-ends and energy-harvesting circuits |
| Diode capacitance Cd | 75 pF at VR = 0 V, f = 1 MHz - low parasitic capacitance preserves signal integrity in RF-coupled bias networks |
Pinout & Package
SOD882 (DFN1006-2) is a 2-terminal leadless plastic package measuring 1.0 × 0.6 × 0.5 mm, with cathode identified by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed to maintain reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 μA - enables stable regulation in micro-power systems where supply current is constrained |
| Tight voltage tolerance | ±2 % (B-series) - eliminates need for external trimming in precision reference applications |
| Ultra-small footprint | DFN1006-2 (1.0 × 0.6 mm) - saves board space in wearables, IoT sensors, and multi-rail PMIC support rails |
| Optimized leakage profile | Intentional minor rise per AN90031 - reduces switching noise and improves transient response in feedback paths |
| High-temperature capability | Rated to +150 °C junction - supports deployment in automotive under-hood or industrial control environments |
Applications
| Portable Sensor Biasing | Low-Power ADC Reference |
|---|---|
|
Use Scenario: Providing stable excitation voltage to MEMS pressure sensors in battery-operated environmental monitors. IC Role / Device Role / Timing Role: Zener voltage reference supplying 15 V bias to sensor bridge with <0.1 % drift over 0–50 °C. Use Value: 50 μA test current matches sensor quiescent draw, eliminating need for additional current source and reducing system standby power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-C15 | ±5 % tolerance, higher leakage (~0.1 μA at 12 V), same package and VZ range | Acceptable where cost sensitivity outweighs precision; less suitable for <12-bit measurement systems | Select when budget constraints dominate and ±5 % regulation error is acceptable in final system margin |
| MMSZ5245B | Same 15 V nominal, ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot | Larger footprint but higher power handling; not suitable for ultra-dense layouts | Choose when board space allows larger package and higher surge immunity is required in industrial field interfaces |
Compared with BZX8850-C15, the BZX8850-B15YL offers tighter tolerance and lower leakage for precision biasing; versus MMSZ5245B, it trades power rating for 65 % smaller area-critical in miniaturized edge devices.

FAQ
What is the maximum continuous reverse current the BZX8850-B15YL can sustain without degradation?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its reverse current is limited by power dissipation. At 15 V Zener voltage and 250 mW total power, the absolute maximum continuous reverse current is 16.7 mA (250 mW ÷ 15 V). Exceeding this risks thermal runaway unless heatsinking or derating is applied per ambient conditions.
Can BZX8850-B15YL be used in series or parallel configurations for higher voltage or current capability?
Series connection is viable for higher reference voltages (e.g., two 15 V units yield ~30 V), but matching tolerance and temperature coefficients is critical to avoid imbalance. Parallel use is strongly discouraged due to negative dynamic resistance characteristics-minor VZ mismatch causes current hogging and thermal failure.
How does the "intentional minor rise of leakage current" affect circuit stability in feedback loops?
Per AN90031, the controlled leakage increase reduces minority-carrier lifetime, lowering stored charge and enabling faster recovery from transient overvoltage. In op-amp feedback references, this suppresses ringing and overshoot during step-load changes-improving settling time without added compensation components.
Is the SOD882 package compatible with standard reflow profiles for lead-free soldering?
Yes-the DFN1006-2 outline complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Figure 10 in the datasheet specifies the recommended solder paste stencil and land pattern for reliable void-free attachment on FR4 boards.
