Product details
Overview
BZX284-B5V1,115 from NXP Semiconductors is a ±2% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 5.1 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 400 Ω maximum differential resistance. It serves as a precision low-power voltage reference in power supply feedback paths, overvoltage protection circuits, and analog signal conditioning stages.
For engineers reviewing the BZX284-B5V1,115 datasheet, BZX284-B5V1,115 pinout, BZX284-B5V1,115 application, or BZX284-B5V1,115 equivalent, key selection criteria include its 5.1 V regulation accuracy, 2 μA reverse leakage at 2 V, −0.8 mV/K temperature coefficient, and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BZX284-B5V1,115 operates as a two-terminal silicon Zener diode optimized for stable reverse-bias breakdown regulation. Its junction temperature range spans −65 °C to +150 °C, with thermal resistance from junction to ambient of 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB.
Electrical behavior is defined under DC conditions at Tj = 25 °C: forward voltage is 0.9 V at 10 mA, reverse current is capped at 2 μA at VR = 2 V, and non-repetitive peak reverse surge current reaches 12 A for 100 μs pulses.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Same 5.1 V nominal, ±5% tolerance, SOD-123 package, 200 mW rating | Lower power rating requires derating in >5 mA loads; larger SOD-123 footprint | Select when cost sensitivity outweighs precision and board space constraints |
| BZX84-C5V1 | Same 5.1 V nominal, ±5% tolerance, SOT-23 package, 300 mW rating, higher leakage (5 μA) | Plastic package offers lower moisture sensitivity but higher thermal resistance (450 K/W) | Select for reflow-compatible plastic SMT processes where ±5% tolerance is acceptable |
Compared with MMBZ5221BS-7-F and BZX84-C5V1, the BZX284-B5V1,115 delivers tighter ±2% regulation, higher 400 mW power capability, and superior thermal performance in a smaller ceramic SOD110 package-making it optimal for precision, space-limited, and thermally demanding applications.

FAQ
What is the nominal Zener voltage and test current for BZX284-B5V1,115?
The BZX284-B5V1,115 has a nominal Zener voltage of 5.1 V measured at a test current of 5 mA. This value falls within the guaranteed range of 5.00 V to 5.20 V at 25 °C, reflecting its ±2% tolerance specification. The 5 mA test condition aligns with standard industry practice for low-voltage Zener characterization and ensures repeatability in design validation.
What package type does BZX284-B5V1,115 use and what are its dimensions?
The BZX284-B5V1,115 uses the SOD110 very small ceramic surface-mount package, measuring 2.10 mm × 1.40 mm × 1.60 mm. Its outline features a cathode band marking on one end, with anode and cathode terminals exposed on opposite sides of the rectangular body. This ceramic construction provides superior thermal stability and moisture resistance compared to plastic alternatives.
What is the maximum reverse leakage current for BZX284-B5V1,115 and under what condition?
The BZX284-B5V1,115 exhibits a maximum reverse leakage current of 2 μA at a reverse voltage of 2 V and ambient temperature of 25 °C. This low leakage supports energy-efficient operation in always-on protection circuits and minimizes loading effects in high-impedance reference nodes, directly contributing to system-level power budget accuracy.
How does the temperature coefficient of BZX284-B5V1,115 affect its regulation stability?
The BZX284-B5V1,115 has a temperature coefficient of −0.8 mV/K at 5 mA test current, meaning its Zener voltage decreases by approximately 0.8 mV per degree Celsius rise in junction temperature. This negative coefficient enables predictable drift compensation in multi-diode reference networks and supports stable operation across the −65 °C to +150 °C junction temperature range.
Can BZX284-B5V1,115 be used in place of BZX284-C5V1 in existing designs?
No, BZX284-B5V1,115 is not a direct replacement for BZX284-C5V1 due to its tighter ±2% tolerance versus the ±5% tolerance of the C-series part. While both share identical package, voltage rating, and basic electrical characteristics, substituting BZX284-B5V1,115 may alter loop gain or trip thresholds in circuits calibrated for wider tolerance. Validation of regulation accuracy and thermal behavior is required before interchange.
