Product details
Overview
BZX284-C5V6,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation, with nominal Zener voltage 5.6 V at 5 mA test current, differential resistance ≤400 Ω, and temperature coefficient +1.2 mV/K - used for low-power voltage reference and overvoltage protection in sensor signal conditioning circuits.
For engineers reviewing the BZX284-C5V6,115 datasheet, BZX284-C5V6,115 pinout, BZX284-C5V6,115 application, or BZX284-C5V6,115 equivalent, key selection criteria include Zener voltage tolerance (±5%), reverse leakage current (1 μA at 2 V), thermal resistance (315 K/W), and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a two-terminal passive voltage reference, relying on controlled reverse breakdown in silicon PN junction. Its regulation performance is defined at IZ = 5 mA, with specified differential resistance indicating dynamic impedance under small-signal AC conditions.
The SOD110 package enables surface-mount assembly on standard FR-4 PCBs (11 × 25 × 1.6 mm board), and its ceramic construction provides stable thermal and electrical characteristics across −65 °C to +150 °C storage temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - defines precise DC reference point for biasing or clamping |
| Tolerance | ±5% - specifies maximum allowable deviation from nominal 5.6 V under production conditions |
| Differential Resistance (rdif) | ≤400 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | 1 μA at VR = 2 V - sets minimum operating current threshold before breakdown conduction begins |
| Total Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C - limits continuous DC power handling without derating |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius, critical for temperature-stable references |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation |
Pinout & Package
SOD110 is a 2-terminal ceramic surface-mount package with cathode marked by a band on one end. Dimensions: 2.10 × 1.40 × 1.60 mm (L × W × H). Mounting requires reflow-compatible solder paste and standard 0805-class stencil apertures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Forward conduction terminal / low-voltage side | Connected to ground or lower-potential node during reverse-bias regulation |
| Cathode (2) | Reverse breakdown terminal / high-voltage side | Connected to supply rail or signal node requiring clamping or reference; marked with band |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD110 ceramic package | Enables high-density layout in portable and IoT sensor modules where height < 1.6 mm is mandatory |
| ±5% Zener voltage tolerance | Supports cost-sensitive applications where tighter tolerance is unnecessary, reducing BOM cost vs. ±2% B-series |
| 400 mW power rating | Provides sufficient headroom for transient surge suppression in 3.3 V/5 V logic interfaces without external series resistor oversizing |
| 1 μA reverse leakage at 2 V | Minimizes quiescent current draw in battery-powered systems operating near the Zener knee voltage |
| +1.2 mV/K temperature coefficient | Ensures predictable, low-drift behavior in ambient-temperature-varying environments like automotive cabin sensors |

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-C5V6 | Same SOD-123 package; ±5% tolerance; 500 mW Ptot; 1.5 μA IR at 2 V | Higher power rating allows larger series resistor for same current, but larger footprint than SOD110 | Select when higher surge energy handling is required and board area permits SOD-123 |
| Vishay BZX84-C5V6 | SOT-23 package; ±5% tolerance; 300 mW Ptot; 1 μA IR at 2 V; 500 Ω rdif | Three-pin SOT-23 offers same pin count but different pad layout; lower power rating demands tighter current control | Select when existing SOT-23 footprint is fixed and 300 mW suffices for target bias current |
Compared with BZX284-C5V6,115, the BZT52-C5V6 offers higher power margin in a larger package, while the BZX84-C5V6 trades power and impedance for standardized SOT-23 placement - choice depends on board space, thermal budget, and existing layout constraints.

FAQ
What is the Zener voltage tolerance of the BZX284-C5V6,115?
The BZX284-C5V6,115 has a ±5% Zener voltage tolerance, meaning its actual breakdown voltage falls between 5.49 V and 5.71 V when tested at 5 mA. This tolerance reflects production binning for cost-optimized regulation where tighter ±2% (B-series) is not required. The BZX284-C5V6,115 maintains this specification across its full operating temperature range.
Can the BZX284-C5V6,115 be used in place of a BZX284-B5V6?
No - the BZX284-C5V6,115 and BZX284-B5V6 differ in voltage tolerance (±5% vs. ±2%) and differential resistance (≤400 Ω vs. ≤480 Ω at 5 mA), resulting in distinct regulation accuracy and dynamic impedance. Substituting BZX284-C5V6,115 for BZX284-B5V6 may degrade reference stability in precision analog circuits. The BZX284-C5V6,115 is not a drop-in replacement for the BZX284-B5V6.
What is the maximum reverse leakage current for the BZX284-C5V6,115 at 2 V?
The maximum reverse leakage current for the BZX284-C5V6,115 is 1 μA at VR = 2 V and Tj = 25 °C. This value is confirmed in Table 1 of the NXP datasheet and defines the upper bound of off-state current before entering the Zener breakdown region. Designers must ensure bias networks keep voltage below 2 V when the BZX284-C5V6,115 is inactive to avoid unintended conduction.
Does the BZX284-C5V6,115 have a positive or negative temperature coefficient?
The BZX284-C5V6,115 has a positive temperature coefficient of +1.2 mV/K at IZ = 5 mA, as specified in Table 1. This means its Zener voltage increases by approximately 1.2 mV for every 1 °C rise in junction temperature. This characteristic is typical for Zener diodes above ~5 V and must be factored into thermal design for applications requiring stable reference voltage across temperature extremes.
What package type does the BZX284-C5V6,115 use, and what are its dimensions?
The BZX284-C5V6,115 uses the SOD110 very small ceramic SMD package, with outline dimensions of 2.10 mm × 1.40 mm × 1.60 mm (length × width × height). The cathode is marked by a band on one end. This package is optimized for high-density PCB layouts and complies with JEDEC standards for reflow soldering. The BZX284-C5V6,115's SOD110 footprint differs from SOD-123 and SOT-23, requiring dedicated land patterns.
