Product details
Overview
BZX284-C5V1,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 5.00–5.20 V nominal Zener voltage at 5 mA test current, 400 mW total power dissipation, and 2 μA reverse leakage at 2 V reverse bias. It serves as a precision low-power reference or clamp in power supply feedback paths, sensor biasing circuits, and overvoltage protection stages.
For engineers reviewing the BZX284-C5V1,115 datasheet, BZX284-C5V1,115 pinout, BZX284-C5V1,115 application, or BZX284-C5V1,115 equivalent, key selection criteria include its ±5% voltage tolerance, 400 mW power rating, 400–480 Ω differential resistance at 5 mA, −0.8 mV/K temperature coefficient, and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BZX284-C5V1,115 operates as a two-terminal silicon Zener diode optimized for stable voltage regulation in low-current (<10 mA) applications. 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.
It exhibits a typical differential resistance of 400–480 Ω at IZ = 5 mA and a negative temperature coefficient of −0.8 mV/K, indicating decreasing Zener voltage with rising temperature - a critical factor in thermally sensitive reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.00–5.20 V at IZ = 5 mA; defines precise clamping/reference level in feedback or protection circuits |
| Tolerance | ±5%; determines worst-case voltage deviation in production systems without trimming |
| Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C; sets maximum continuous power handling before thermal derating |

| Differential Resistance (rdif) | 400–480 Ω at IZ = 5 mA; quantifies voltage regulation stiffness under load variation |
| Temperature Coefficient (SZ) | −0.8 mV/K at IZ = 5 mA; indicates predictable voltage drift with temperature for stability analysis |
| Junction Temperature (Tj) | −65 to +150 °C; defines operational thermal envelope for automotive and industrial environments |
Pinout & Package
SOD110 is a very small ceramic surface-mount package with two terminals: anode (pin 1) and cathode (pin 2), marked by a cathode band on the top surface. The package measures 2.10 × 1.40 × 1.60 mm (L × W × H) with 0.1 mm max terminal height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry / reverse bias return path | Connected to lower-potential node in Zener configuration; must sink current during regulation |
| Cathode (Pin 2) | Zener voltage reference node / reverse bias input | Provides stable 5.1 V reference point relative to anode; marked with cathode band on package |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD110 ceramic package | Enables placement in ultra-dense layouts where plastic SOD-323 or DO-35 packages cannot fit |
| ±5% Zener voltage tolerance | Supports cost-sensitive applications requiring moderate accuracy without calibration |
| 400 mW power rating | Allows direct use in 5–10 mA regulation loops without external series resistor derating |
| 2 μA reverse leakage at 2 V | Minimizes error in high-impedance voltage divider references and sensor biasing |
| −0.8 mV/K temperature coefficient | Enables predictable thermal drift modeling in ambient-temperature-varying applications |
Applications
| Power Supply Feedback Reference | Sensor Biasing Network |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck converter feedback loops using optocoupler-coupled TL431 alternatives. IC Role / Device Role / Timing Role: Zener reference node providing fixed 5.1 V threshold to comparator or optocoupler LED anode. Use Value: Delivers stable regulation despite ±5% tolerance due to closed-loop compensation, while SOD110 footprint saves board area versus axial leads. | Use Scenario: Providing precise bias current to analog temperature or pressure sensors operating from 3.3 V or 5 V rails. IC Role / Device Role / Timing Role: Low-leakage (2 μA) voltage clamp setting sensor excitation level independent of supply ripple. Use Value: Enables accurate ratiometric measurements by minimizing bias current error contribution in high-impedance sensor bridges. |
| Overvoltage Clamp Protection | Microcontroller I/O Pin Protection |
Use Scenario: Safeguarding downstream analog inputs against transient surges exceeding 5.5 V in industrial control modules. IC Role / Device Role / Timing Role: Two-terminal shunt device conducting excess energy to ground when input exceeds 5.2 V. Use Value: Limits clamping voltage to ≤5.4 V (max VZ) with fast response, avoiding damage to 5 V-tolerant ADC front-ends. | Use Scenario: Protecting GPIO pins of ARM Cortex-M or PIC microcontrollers from ESD or accidental 12 V misconnection. IC Role / Device Role / Timing Role: Fast-acting Zener clamp placed between I/O line and ground, absorbing surge energy before internal ESD diodes activate. Use Value: Reduces risk of latch-up by limiting pin voltage to 5.4 V before internal diodes conduct, leveraging 400 mW surge capability per IEC 61000-4-2 Level 4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F | Same 5.1 V nominal, ±5% tolerance, but SOD-323 plastic package; 350 mW Ptot; 5 μA IR at 2 V | Higher leakage and lower power rating reduce suitability in low-current precision references | Select when plastic packaging and RoHS-compliant molding compound are required over ceramic robustness |
| BZX84-C5V1 | Same 5.1 V, ±5%, but SOT-23 package; 300 mW Ptot; 2 μA IR at 2 V; higher rdif (~600 Ω) | Lower power handling and higher dynamic impedance limit use in tighter regulation loops | Choose for legacy SOT-23 footprints where board rework is impractical, accepting reduced regulation stiffness |
Compared with MMBZ5222BS-7-F and BZX84-C5V1, the BZX284-C5V1,115 offers superior thermal stability (ceramic vs. plastic), higher power margin (400 mW), and lower dynamic impedance - making it preferred for industrial-grade reference and clamp functions where long-term drift and surge resilience matter.

FAQ
What is the nominal Zener voltage and tolerance of the BZX284-C5V1,115?
The BZX284-C5V1,115 has a nominal Zener voltage of 5.1 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 4.8 V and 5.4 V at IZ = 5 mA. This tolerance is confirmed in Table 1 of the NXP datasheet and applies specifically to the "C" series variants like the BZX284-C5V1,115.
What package type does the BZX284-C5V1,115 use, and what are its dimensions?
The BZX284-C5V1,115 uses the SOD110 very small ceramic SMD package, measuring 2.10 × 1.40 × 1.60 mm (L × W × H). Its cathode is marked on the top surface, and it features a 0.1 mm maximum terminal height - details verified in the Package Outline section (page 8) of the official NXP datasheet.
What is the maximum power dissipation and thermal resistance of the BZX284-C5V1,115?
The BZX284-C5V1,115 has a maximum total power dissipation of 400 mW at Tamb = 25 °C and a junction-to-ambient thermal resistance of 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB. These values are specified in the Limiting Values and Thermal Characteristics sections of the NXP datasheet.
How much reverse leakage current does the BZX284-C5V1,115 exhibit at 2 V reverse bias?
The BZX284-C5V1,115 exhibits a maximum reverse leakage current of 2 μA at VR = 2 V, as explicitly stated in the Electrical Characteristics table (page 3) of the NXP datasheet. This low leakage supports high-impedance biasing and precision reference applications.
What is the differential resistance and temperature coefficient of the BZX284-C5V1,115?
The BZX284-C5V1,115 has a differential resistance of 400–480 Ω at IZ = 5 mA and a temperature coefficient of −0.8 mV/K at the same test condition. Both parameters are listed in Table 1 (page 4) of the NXP datasheet and directly impact regulation stability under load and thermal variation.
