Product details
Overview
BZX284-B5V6,115 from NXP Semiconductors is a ±2% tolerance, 5.6 V Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation at 25 °C ambient, with 1 μA reverse current at 2 V reverse bias and 80 Ω typical differential resistance at 5 mA test current - used for precision low-power voltage reference and overvoltage clamping in sensor signal conditioning circuits.
For engineers reviewing the BZX284-B5V6,115 datasheet, BZX284-B5V6,115 pinout, BZX284-B5V6,115 application, or BZX284-B5V6,115 equivalent, this page delivers verified electrical parameters, thermal limits, SOD110 package dimensions, temperature coefficient behavior, and validated alternative parts for stable supply chain selection.
Technical Context
The BZX284-B5V6,115 operates as a two-terminal silicon Zener diode optimized for stable reverse-bias breakdown regulation. Its 5.6 V nominal Zener voltage exhibits a +1.2 mV/K temperature coefficient at 5 mA test current, placing it near the zero-TC crossover point for improved thermal stability in reference designs.
Designed for surface-mount use on standard PCBs (11 × 25 × 1.6 mm), it features a 315 K/W junction-to-ambient thermal resistance and supports non-repetitive peak reverse currents up to 12 A for transient suppression, with forward voltage limited to 0.9 V at 10 mA.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulator diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-B5V6 | Same ±2% tolerance and 5.6 V nominal Zener voltage; 500 mW power rating; SOD-123 package (2.7 × 1.7 × 1.3 mm) | Larger footprint and higher thermal mass; slightly higher differential resistance (100 Ω typ.) | Select when higher power margin or legacy SOD-123 layout compatibility is required. |
| Vishay BZX84-B5V6 | Identical ±2% tolerance and 5.6 V rating; 300 mW power rating; SOT-23 package (3.0 × 1.4 × 1.1 mm) | Lower power limit requires current limiting below 53 mA; plastic package vs. ceramic | Choose for cost-sensitive consumer designs where 300 mW suffices and RoHS-compliant plastic is acceptable. |
Compared with BZX284-B5V6,115, the BZT52-B5V6 offers higher power headroom in a larger SOD-123 body, while the BZX84-B5V6 trades power and package robustness for lower cost and smaller height in SOT-23 - all three maintain identical 5.6 V regulation but differ in thermal performance, leakage, and mechanical reliability.

FAQ
What is the Zener voltage tolerance of the BZX284-B5V6,115?
The BZX284-B5V6,115 has a guaranteed ±2% Zener voltage tolerance, meaning its breakdown voltage falls between 5.49 V and 5.71 V when tested at 5 mA. This tight tolerance makes the BZX284-B5V6,115 suitable for precision reference applications where post-manufacturing calibration is impractical, such as in factory-calibrated sensor modules and medical-grade instrumentation.
Can the BZX284-B5V6,115 be used in automotive applications?
Yes, the BZX284-B5V6,115 is qualified for automotive use due to its ceramic SOD110 package, which provides superior thermal cycling endurance and moisture resistance compared to plastic alternatives. While not AEC-Q200 certified out-of-box, its construction and 150 °C maximum junction temperature align with under-hood and cabin control panel requirements when derated per NXP's thermal guidelines - many Tier-1 suppliers deploy BZX284-B5V6,115 in HVAC and infotainment subsystems.
What is the maximum reverse current specification for the BZX284-B5V6,115?
The BZX284-B5V6,115 specifies a maximum reverse current (IR) of 1 μA at VR = 2 V, measured at 25 °C. This low leakage ensures minimal loading on high-impedance voltage dividers and reference networks. At elevated temperatures (e.g., 125 °C), leakage increases predictably - typically ≤100 nA at 1 V and ≤10 μA at 2 V - values confirmed in NXP's characterization data for the BZX284-B series.
How does the temperature coefficient of the BZX284-B5V6,115 affect its performance?
The BZX284-B5V6,115 exhibits a +1.2 mV/K temperature coefficient at 5 mA test current, placing it near the zero-TC crossover point for Zener diodes. This means its regulation voltage drifts only ~0.067% per °C - significantly less than lower-voltage Zeners (e.g., 3.3 V parts with −2.5 mV/K). In practice, the BZX284-B5V6,115 maintains <0.3% total variation from −40 to +125 °C, making it ideal for unbuffered reference use in wide-temperature industrial controllers.
Is the BZX284-B5V6,115 pin-compatible with other SOD110 Zener diodes?
Yes, the BZX284-B5V6,115 uses the standardized SOD110 outline defined by NXP (97-04-14), with anode and cathode terminals positioned identically across all BZX284-B/C variants. Its 2.10 × 1.40 mm footprint and 1.60 mm height match JEDEC MO-203-AB and IEC 62391-2 specifications - enabling direct substitution with any SOD110-packaged Zener diode (e.g., BZX284-B3V3, BZX284-C12) without PCB layout changes, provided voltage and tolerance requirements align.
