Product details
Overview
BZX8850-B13YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 13 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, features 12.35–13.65 V working range, 170 Ω differential resistance at 5 mA, and operates up to 150 °C junction temperature-ideal for battery-powered sensor nodes and portable voltage monitoring circuits.
For engineers reviewing the BZX8850-B13YL datasheet, BZX8850-B13YL pinout, BZX8850-B13YL application, or BZX8850-B13YL equivalent, this page provides verified electrical characteristics, thermal limits, package dimensions, marking code (89), and real-world use context for low-power regulation and noise-sensitive biasing.
Technical Context
This Zener diode operates in reverse breakdown mode with specified regulation at IZ = 50 µA, enabling ultra-low quiescent current design. Its 12.35–13.65 V nominal Zener voltage range and ±2 % tolerance ensure tight reference accuracy under minimal bias conditions.
The device exhibits a temperature coefficient of +7.0 mV/K and diode capacitance of 80 pF at 1 MHz, supporting stable performance in low-noise analog signal chains. Its intentional minor leakage rise improves switching speed and reduces high-frequency noise per AN90031.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V at IZ = 5 mA - defines precise regulation window for 13 V reference circuits |
| Tolerance | ±2 % - ensures tight voltage matching across production batches for calibration-critical designs |
| Differential Resistance (rdiff) | 170 Ω max at IZ = 5 mA - determines load regulation error and output impedance in shunt regulator topologies |
| Test Current (IZ) | 50 µA - enables operation from microamp-level bias sources, critical for energy-harvesting and coin-cell applications |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines forward conduction loss when used in bidirectional protection or clamping configurations |
| Junction Temperature (Tj) | −55 to +150 °C - supports operation in extended industrial environments without derating below −40 °C |
Pinout & Package
SOD882 (DFN1006-2) is a leadless ultra-small surface-mount package measuring 1.0 × 0.6 × 0.5 mm, with cathode marked by a 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; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables direct use with high-impedance voltage dividers and nanoamp-level bias networks |
| Optimized leakage profile | Intentional minor IR rise per AN90031 - reduces switching transients and broadband noise in precision analog stages |
| Ultra-compact footprint | DFN1006-2 (1.0 × 0.6 mm) - saves board space in wearables, IoT sensors, and multi-rail PMIC monitoring circuits |
| Stable temperature coefficient | +7.0 mV/K - minimizes drift over −40 to +85 °C ambient, supporting accurate references without external compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | ±5 % tolerance, SOT-23 package (3.0 × 1.4 mm), 350 mW Ptot, rdiff = 20 Ω @ 5 mA | Higher power and lower dynamic impedance but 5× larger footprint and looser voltage accuracy | Select when higher surge robustness and tighter regulation under load are prioritized over size and battery life |
| MMSZ5243B | ±5 % tolerance, SOD-123 package (3.7 × 1.6 mm), 500 mW Ptot, VZ = 13.0 V min/max not specified at 50 µA | Higher power rating but lacks low-current specification and has no documented leakage optimization | Choose only for non-battery applications requiring >300 mW dissipation and where 50 µA operation is unnecessary |
Compared with BZX8850-B13YL, BZX84-C13 offers better load regulation but sacrifices PCB area and low-IZ accuracy; MMSZ5243B supports higher power but cannot guarantee stable 13 V reference at microamp bias levels required in energy-constrained systems.

FAQ
What is the marking code for BZX8850-B13YL?
The marking code for BZX8850-B13YL is '89', laser-etched on the top surface of the DFN1006-2 package adjacent to the cathode bar. This two-character code uniquely identifies the 13 V ±2 % variant within the BZX8850-B series and matches Table 4 in the official Nexperia datasheet Rev. 1 (2024-07-17).
Can BZX8850-B13YL be used in place of a 13 V Zener with ±5 % tolerance?
No-BZX8850-B13YL has ±2 % tolerance (12.35–13.65 V), while ±5 % variants like BZX8850-C13 span 12.35–13.65 V only at 25 °C and widen to 11.7–14.3 V over temperature. Substituting requires verifying circuit margin for worst-case VZ shift, especially in precision references where ±2 % ensures tighter system-level accuracy.
What is the maximum reverse current at 12 V for BZX8850-B13YL?
At 12 V reverse bias and Tamb = 25 °C, the typical reverse current is <0.05 µA, with a maximum of 0.1 µA per Table 8. This ultra-low leakage preserves battery life in always-on monitoring circuits and ensures minimal loading on high-impedance voltage dividers used for reference scaling.
Does BZX8850-B13YL require heatsinking in standard PCB layouts?
No-its 250 mW total power dissipation rating assumes mounting on standard FR4 PCB with single-sided copper and tin plating (per datasheet condition [2]). At 13 V × 10 mA = 130 mW operation, junction temperature rise is ~65 K above ambient, staying well below the 150 °C limit without additional thermal relief or copper pour.
