Product details
Overview
BZX8850-C16YL 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 15.2–16.8 V working voltage range, 200 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient. Used in battery-powered sensor biasing and low-power analog reference circuits.
For engineers reviewing the BZX8850-C16YL datasheet, BZX8850-C16YL pinout, BZX8850-C16YL application, or BZX8850-C16YL equivalent, this page provides verified Zener voltage, leakage behavior, thermal resistance, package dimensions, and substitution guidance for portable and space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified 16 V nominal Zener voltage at IZ = 50 μA, optimized for ultra-low-bias applications. Its differential resistance of 200 Ω at 5 mA ensures predictable voltage deviation under small load variations.
The device features intentional minor leakage rise per AN90031 to improve switching speed and reduce noise-critical for precision analog front-ends. Thermal resistance Rth(j-a) 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 | 15.2–16.8 V at IZ = 50 μA; defines tight regulation window for 16 V reference design |
| Differential Resistance rdiff | 200 Ω at IZ = 5 mA; determines output impedance and load regulation sensitivity |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA; enables use as low-drop rectifier or clamp in dual-role circuits |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C; sets maximum steady-state bias current limit (~15.6 mA at 16 V) |
| Junction Temperature Tj | −55 to +150 °C; supports operation in extended industrial environments without derating below −40 °C |
| Reverse Current IR | ≤ 0.05 μA at VR = 12.1 V; ensures minimal quiescent drain in high-impedance reference nodes |
| Package | SOD882 (DFN1006-2); 1.0 × 0.6 × 0.5 mm footprint ideal for 0201-class PCB real estate constraints |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, ultra-small surface-mount package with exposed copper terminals on the bottom and cathode marking bar on the top surface. Dimensions: 1.02 mm × 0.62 mm × 0.50 mm. Mounting requires reflow-compatible solder land pattern per Figure 10.
| Pin/Terminal | Circuit Role | Design Meaning |

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 | SC-70 package (2.2 × 1.35 mm); 350 mW Ptot; ±5 % tolerance; rdiff = 40 Ω at 5 mA | Higher power handling but 2.2× larger footprint; looser tolerance increases reference uncertainty | Select when higher surge immunity or legacy SC-70 layout compatibility is required |
| MMSZ5245B | SOD-123 package (3.7 × 1.6 mm); 500 mW Ptot; ±5 % tolerance; VZ = 15.6–16.4 V at 20 mA | Higher test current (20 mA) demands more bias power; larger size limits miniaturized designs | Choose for cost-sensitive industrial boards where PCB area is not constrained |
Compared with BZX8850-C16YL, BZX84-C16 offers better surge robustness but sacrifices precision and size; MMSZ5245B trades ultra-low bias operation for higher power capacity and relaxed tolerance-making the C16YL optimal for space- and current-constrained 16 V reference nodes.

FAQ
What is the exact Zener voltage range for BZX8850-C16YL at 50 µA test current?
The BZX8850-C16YL has a guaranteed Zener voltage range of 15.2 V to 16.8 V when measured at IZ = 50 μA and Tj = 25 °C, per Table 8 of the official Nexperia datasheet Rev. 1 (17 July 2024). This ±2 % tolerance is tighter than the B-series (±5 %) and directly supports precision reference design.
Can BZX8850-C16YL be used in forward conduction mode?
Yes-its forward voltage is specified at ≤ 0.9 V at IF = 10 mA (Table 1), making it usable as a low-VF clamp or protection diode. However, its primary design intent and characterization are for reverse-biased Zener regulation; forward characteristics are secondary and not optimized for rectification duty cycles.
How does the "intentional minor rise of leakage current" affect circuit performance?
Per Application Note AN90031 cited in the datasheet, this controlled leakage increase reduces junction capacitance and noise, improving switching speed and spectral purity in analog signal paths. It does not compromise DC regulation accuracy-VZ remains tightly specified at 50 μA, while dynamic behavior benefits in AC-coupled or fast-transient applications.
What is the recommended PCB footprint for SOD882 mounting?
The official reflow soldering footprint (Figure 10) specifies two 0.3 mm × 0.9 mm solder lands with 0.6 mm center-to-center spacing, 0.7 mm overall pad length, and 0.4 mm width. Solder mask openings must fully expose pads; stencil aperture should match land dimensions to avoid bridging or insufficient paste volume in the 0.5 mm height package.
