Product details
Overview
BZX284-C3V6,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 3.53–3.67 V nominal Zener voltage at 5 mA test current, 400 mW total power dissipation, and 375–500 Ω differential resistance. 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-C3V6,115 datasheet, BZX284-C3V6,115 pinout, BZX284-C3V6,115 application, or BZX284-C3V6,115 equivalent, this part supports stable 3.6 V regulation in space-constrained SMD designs where thermal resistance (315 K/W) and low reverse leakage (5 μA at 1 V) are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified Zener voltage tolerance of ±5%, tested at IZ = 5 mA. Its differential resistance ranges from 375 Ω (typ.) to 500 Ω (max.), indicating moderate regulation stiffness under varying load currents.
The device exhibits a negative temperature coefficient of −2.4 mV/K at 5 mA, meaning its Zener voltage decreases slightly with rising junction temperature - a key factor when used in temperature-sensitive references or unregulated environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53–3.67 V at IZ = 5 mA; defines precise clamping threshold for 3.6 V nominal systems. |
| Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C; sets maximum continuous power handling without derating. |
| Differential Resistance (rdiff) | 375–500 Ω at IZ = 5 mA; determines output impedance and regulation sensitivity to current changes. |
| Reverse Leakage (IR) | 5 μA at VR = 1 V; ensures minimal parasitic current draw in standby or high-impedance bias networks. |
| Temperature Coefficient (SZ) | −2.4 mV/K at IZ = 5 mA; quantifies voltage drift per degree Celsius for thermal stability analysis. |
| Junction Temperature (Tj) | 150 °C max; defines upper thermal limit for reliable long-term operation. |
| Package | SOD110 ceramic SMD; 1.9–2.1 mm length, 1.1–1.4 mm width, 1.6 mm height; enables ultra-compact PCB layout. |
Pinout & Package
SOD110 is a two-terminal surface-mount ceramic package with cathode marked by a band on one end. Terminals are non-polarized in function but polarity-critical in circuit connection: anode connects to lower potential, cathode to higher potential during reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side terminal | Connected to ground or reference node; carries forward current during conduction or sink current during Zener regulation. |
| Cathode (banded end) | High-side terminal | Connected to regulated rail or input; defines Zener breakdown voltage relative to anode potential. |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener tolerance | Enables cost-optimized voltage reference selection where tight regulation is secondary to footprint and procurement simplicity. |
| 400 mW power rating | Supports robust transient suppression and steady-state biasing in low-to-moderate current applications (<250 mA forward). |
| SOD110 ceramic package | Provides superior thermal stability and moisture resistance vs. plastic SMD packages, critical for industrial ambient reliability. |
| Low 5 μA reverse leakage at 1 V | Minimizes quiescent current error in high-impedance feedback dividers and battery-backed sensing nodes. |
| −2.4 mV/K tempco | Allows predictable compensation in dual-diode or thermally coupled reference designs targeting zero-drift behavior. |
Applications
| Power Supply Feedback Clamping | Sensor Bias Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.3 V nominal, ±5%, SOT-23 package, 225 mW Ptot, 600 Ω rdiff | Lower voltage and power rating; less suitable for 3.6 V rail clamping or higher-current biasing. | Select when footprint compatibility with SOT-23 is required and 3.3 V regulation suffices. |
| BZX84-C3V6,215 | Same 3.6 V rating and ±5% tolerance, but in SOT-23 plastic package; 300 mW Ptot, 600 Ω rdiff | Higher thermal resistance and lower moisture resistance than ceramic SOD110; reduced long-term stability in humid environments. | Choose for cost-sensitive consumer designs where ceramic reliability is not mandated. |

FAQ
What is the Zener voltage tolerance of BZX284-C3V6,115?
The BZX284-C3V6,115 has a nominal Zener voltage of 3.6 V with a guaranteed tolerance of ±5%, meaning its actual breakdown voltage falls between 3.4 V and 3.8 V when tested at 5 mA. This tolerance is confirmed in Table 1 of the NXP datasheet and applies specifically to the 'C' series variant of the BZX284-C3V6,115.
What is the maximum power dissipation for BZX284-C3V6,115?
The BZX284-C3V6,115 has a maximum total power dissipation of 400 mW at ambient temperature of 25 °C, as specified in the Limiting Values table. Derating is required above 25 °C based on its thermal resistance of 315 K/W, and this rating assumes mounting on a standard 11 × 25 × 1.6 mm PCB per the datasheet note.
Does BZX284-C3V6,115 have a defined temperature coefficient?
Yes, the BZX284-C3V6,115 has a typical temperature coefficient of −2.4 mV/K at IZ = 5 mA, as documented in Table 1. This negative coefficient means its Zener voltage decreases by approximately 2.4 mV per degree Celsius rise in junction temperature - a critical parameter for temperature-sensitive reference designs.
What is the reverse leakage current of BZX284-C3V6,115 at 1 V?
The reverse leakage current of BZX284-C3V6,115 is specified as 5 μA maximum at VR = 1 V and Tj = 25 °C. This value is explicitly listed in the Electrical Characteristics table under IR for BZX284-B/C3V6, confirming its suitability for low-current bias and high-impedance sensing applications.
Which package type does BZX284-C3V6,115 use?
The BZX284-C3V6,115 uses the SOD110 package - a very small ceramic surface-mount outline with dimensions of 1.9–2.1 mm in length, 1.1–1.4 mm in width, and 1.6 mm in height. The package features a cathode band marking and is detailed in the Package Outline section (page 8) of the NXP datasheet.
