Product details
Overview
BZX8850-B16YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 16 V nominal with ±2 % tolerance. It delivers stable 16 V reference under 50 μA test current, exhibits 12.1 Ω differential resistance at 5 mA, and supports ambient temperatures from −55 °C to +150 °C - ideal for battery-powered sensor biasing and low-power analog reference circuits.
For engineers reviewing the BZX8850-B16YL datasheet, BZX8850-B16YL pinout, BZX8850-B16YL application, or BZX8850-B16YL equivalent, key selection criteria include its 16 V Zener voltage tolerance, ultra-low 50 μA test current requirement, 250 mW power rating, DFN1006-2 footprint compatibility, and intentional leakage optimization for noise-sensitive signal conditioning.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 16 V (B-series ±2 %), specified at IZ = 50 μA - enabling stable regulation in micro-power circuits where bias current must remain below 100 μA. Its differential resistance of 12.1 Ω at 5 mA ensures minimal voltage shift under load variation.
The device features an intentionally elevated leakage current profile per AN90031, optimized for fast switching transients and reduced broadband noise in precision analog front-ends. Thermal resistance Rth(j-a) is 500 K/W on FR4 PCB, limiting junction temperature rise to 125 K at full 250 mW dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15.2 V to 16.8 V at IZ = 50 μA - tight ±2 % tolerance enables accurate 16 V reference without trimming |
| Differential Resistance rdiff | 200 Ω max at IZ = 50 μA; 12.1 Ω typ at IZ = 5 mA - low dynamic impedance maintains regulation under moderate load changes |
| Power Dissipation Ptot | 250 mW max at Tamb ≤ 25 °C - sufficient for low-power biasing but requires thermal derating above 25 °C |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables use as clamping diode in bidirectional protection schemes |
| Reverse Current IR | ≤ 0.05 μA at VR = 12.1 V - ultra-low leakage preserves battery life in always-on monitoring nodes |
| Package | SOD882 (DFN1006-2): 1.0 × 0.6 × 0.5 mm - ultra-compact footprint for space-constrained wearables and IoT sensors |
| Junction Temperature | −55 °C to +150 °C - supports operation in industrial and automotive under-hood environments |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package with two terminals and a cathode-marked top surface. The body measures 1.0 mm × 0.6 mm × 0.5 mm, with solder pads sized per IPC-7351B standard for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for controlled breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low Test Current Operation | Specified at 50 μA - enables stable 16 V reference in nanoampere-bias circuits like CMOS oscillator timing networks |
| Optimized Leakage Profile | Intentional minor IR increase per AN90031 - reduces high-frequency noise in ADC reference buffers without sacrificing regulation accuracy |
| Tight Voltage Tolerance | ±2 % (B-series) - eliminates need for external trimming in factory-calibrated sensor signal chains |
| Ultra-Small Footprint | DFN1006-2 package - saves >70 % board area vs. traditional SOD-323 Zeners, critical for miniaturized medical patches |
| High-Temperature Rating | 150 °C max junction temperature - supports deployment in sealed enclosures with passive thermal buildup |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | ±5 % tolerance; SOT-23 package (2.9 × 1.3 × 1.0 mm); 350 mW rating; specified at IZ = 5 mA | Higher power handling but larger footprint; less precise voltage; higher test current increases quiescent drain | Select when board space allows larger package and ±5 % tolerance suffices for cost-sensitive consumer electronics |
| MMSZ5245B | ±5 % tolerance; SOD-123 package (3.7 × 1.6 × 1.1 mm); 500 mW rating; 16 V nominal; specified at IZ = 20 mA | Double power rating but 3.7× larger footprint; 400× higher test current limits use in sub-100 μA systems | Choose only for high-reliability industrial controls requiring >300 mW dissipation and legacy SOD-123 layout compatibility |
Compared with BZX8850-B16YL, BZX84-C16 trades voltage precision and micro-power capability for cost and robustness, while MMSZ5245B sacrifices miniaturization and ultra-low bias for thermal headroom - making BZX8850-B16YL uniquely suited for space- and current-constrained precision analog designs.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-B16YL?
The BZX8850-B16YL has a nominal Zener voltage of 16 V with ±2 % tolerance, meaning guaranteed breakdown occurs between 15.2 V and 16.8 V at IZ = 50 μA. Below 15.2 V, reverse current remains ≤0.05 μA - no functional breakdown occurs. Absolute maximum reverse voltage is not defined; operation beyond 16.8 V risks exceeding Ptot limits if current rises.
Can BZX8850-B16YL be used in forward conduction mode?
Yes - it functions as a standard silicon diode in forward bias, with VF ≤ 0.9 V at IF = 10 mA. However, its primary design purpose is reverse-bias Zener regulation; forward characteristics are secondary and not optimized for rectification or switching. Maximum continuous forward current is 200 mA per limiting values table.
How does the "intentional minor rise of leakage current" affect circuit performance?
This feature, detailed in application note AN90031, slightly increases reverse current near breakdown to improve high-frequency noise suppression and transient response. In practice, it reduces broadband noise by up to 6 dB in 10 kHz–1 MHz band and cuts turn-on delay by ~15 ns versus conventional Zeners - beneficial in precision ADC references and RF bias networks.
Is BZX8850-B16YL suitable for automotive applications?
No - the BZX8850-B16YL is not AEC-Q200 qualified. While its −55 °C to +150 °C operating range overlaps automotive requirements, Nexperia explicitly states in the legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or automotive use. For automotive designs, select Nexperia's AEC-Q200-certified Zener families such as PZUxxL.
