Product details
Overview
BZX8850-C15YL from Nexperia is a low-current Zener voltage regulator diode in SOD882 (DFN1006-2) package, designed for precision voltage reference and biasing in ultra-low-power circuits. It delivers a nominal 15 V Zener voltage at 50 µA test current, with ±5 % tolerance, 200 mW total power dissipation, and 200 Ω typical differential resistance at 5 mA - ideal for battery-powered sensor nodes and portable IoT devices.
For engineers reviewing the BZX8850-C15YL datasheet, BZX8850-C15YL pinout, BZX8850-C15YL application, or BZX8850-C15YL equivalent, this page provides verified Zener voltage, leakage behavior, thermal resistance, package dimensions, and direct alternatives for low-bias regulation in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 14.25 V to 15.75 V at IZ = 50 µA, exhibiting a temperature coefficient of +9.2 mV/K and reverse current ≤ 0.05 µA at VR = 11.4 V. Its low 500 K/W junction-to-ambient thermal resistance enables stable operation on FR4 PCBs without heatsinking.
The device features intentional minor leakage optimization per AN90031 for fast switching transients and reduced noise in analog signal chains. Its DFN1006-2 footprint (1.0 × 0.6 × 0.5 mm) supports automated placement and reflow soldering per IPC-7095 guidelines.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | SC-70 package (2.2 × 1.35 mm); 350 mW Ptot; ±5 % tolerance; rdiff = 30 Ω @ 5 mA | Higher power handling but 3.7× larger footprint; better regulation but unsuitable for ultra-dense layouts | Select when higher current capability (>10 mA) and tighter dynamic regulation are required over size constraints |
| MMSZ5245B | SOD-123 package (3.7 × 1.6 mm); 500 mW Ptot; ±5 % tolerance; rdiff = 17 Ω @ 20 mA | Double the power rating and lower impedance, but incompatible with 0201-class placement equipment | Choose for legacy board designs where thermal margin and load regulation dominate over miniaturization goals |
Compared with BZX8850-C15YL, BZX84-C15 offers superior dynamic regulation at higher currents but sacrifices 70 % board area efficiency, while MMSZ5245B delivers robust power handling at the cost of placement compatibility and layout density - making BZX8850-C15YL optimal for next-gen ultra-compact, battery-limited systems.

FAQ
What is the maximum reverse current at 11.4 V for BZX8850-C15YL?
The maximum reverse current (IR) is 0.05 µA at VR = 11.4 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This ultra-low leakage ensures negligible loading on high-impedance bias networks and preserves battery life in always-on monitoring applications.
Can BZX8850-C15YL be used in place of a 1N4744A?
No - the 1N4744A is a 15 V, 1 W through-hole Zener with 16 Ω rdiff and ±5 % tolerance, whereas BZX8850-C15YL is rated for 250 mW, has 200 Ω rdiff, and uses a DFN1006-2 package. Direct substitution requires verifying thermal derating, layout adaptation, and dynamic regulation requirements.
Does BZX8850-C15YL require a heatsink in standard FR4 layouts?
No - its 500 K/W junction-to-ambient thermal resistance and 250 mW power limit allow safe operation up to 125 °C junction temperature on single-sided FR4 PCBs without heatsinking, provided ambient stays ≤ 25 °C and copper area meets standard footprint recommendations in Figure 10.
What does the 'YL' suffix indicate in BZX8850-C15YL?
The 'YL' suffix denotes tape-and-reel packaging per EIA-481-D standard, with 10,000 units per reel and 8 mm carrier tape width - confirming factory-standard logistics configuration for automated SMT assembly, not a parametric variant.
