Product details
Overview
BZX284-B2V7,115 from NXP Semiconductors is a ±2% tolerance, 2.7 V nominal Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation at 25 °C ambient, with 300 Ω typical differential resistance at 5 mA test current and −2.0 mV/K temperature coefficient - used for precision low-power voltage reference and overvoltage clamping in sensor signal conditioning circuits.
For engineers reviewing the BZX284-B2V7,115 datasheet, BZX284-B2V7,115 pinout, BZX284-B2V7,115 application, or BZX284-B2V7,115 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (315 K/W), reverse leakage (20 μA at 1 V), junction temperature limit (150 °C), and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BZX284-B2V7,115 operates as a two-terminal silicon Zener diode optimized for stable reverse-bias breakdown regulation. Its 2.7 V nominal Zener voltage falls within the low-voltage range where temperature coefficient is negative (−2.0 mV/K), requiring careful thermal design to maintain regulation accuracy across operating temperature.
Designed for surface-mount use on standard FR-4 PCBs (11 × 25 × 1.6 mm), it delivers regulated reference voltage under DC or low-frequency transient conditions, with 12 A non-repetitive peak reverse surge capability (tp = 100 μs) and 250 mA continuous forward current rating - supporting both regulation and bidirectional protection roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.65–2.75 V at IZ = 5 mA - ensures tight 2.7 V regulation with ±2% tolerance for stable biasing of low-voltage analog stages. |
| Differential Resistance (rdif) | 300–450 Ω at IZ = 5 mA - defines output impedance affecting load regulation error under varying current draw. |
| Temperature Coefficient (SZ) | −2.0 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius, critical for temperature-sensitive references. |
| Reverse Leakage (IR) | 20 μA at VR = 1 V - determines quiescent power loss and noise contribution in high-impedance sensing nodes. |
| Total Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C - sets maximum steady-state power handling before thermal derating applies. |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation under power stress. |
| Thermal Resistance (Rth j-a) | 315 K/W - indicates how effectively heat transfers from die to ambient, guiding PCB copper area requirements. |
Pinout & Package
SOD110 is a very small ceramic rectangular surface-mounted package with cathode marked by a band on one end. The device has two terminals: anode and cathode - no internal connections beyond the Zener junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference ground node | Connected to circuit common; reverse-bias voltage applied between cathode and this terminal to activate regulation. |
| Cathode (banded end) | Zener voltage output node | Provides stabilized 2.7 V relative to anode when reverse-biased; polarity must be observed to avoid forward conduction. |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance | Enables tighter regulation than ±5% variants (e.g., BZX284-C2V7), reducing calibration overhead in precision analog front-ends. |
| Low 400 mW power rating | Matches energy budgets in battery-powered IoT sensors and wearables where thermal mass and board space are constrained. |
| SOD110 ceramic package | Offers superior moisture resistance and thermal stability vs. plastic SMD packages, supporting industrial-grade reliability. |
| Negative temperature coefficient | −2.0 mV/K behavior allows predictable compensation when paired with positive-TC components in reference networks. |
| 12 A surge rating (100 μs) | Provides transient overvoltage immunity without external TVS, simplifying ESD protection in low-energy interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX284-C2V7,115 | ±5% tolerance (2.5–2.9 V), higher 20–30 μA leakage at 1 V, identical SOD110 package and 400 mW rating. | Acceptable where system-level calibration compensates for wider voltage spread; lower cost for non-critical references. | Select BZX284-C2V7,115 only if ±5% tolerance meets end-equipment specification and leakage budget allows. |
| MMSZ4678T1G | ±5% tolerance (2.5–2.9 V), 500 mW rating, SOD-123 package (larger footprint), 300 Ω rdif, −2.5 mV/K TC. | Requires PCB layout change; higher power rating suits higher-current bias networks but increases board area. | Choose MMSZ4678T1G only when 500 mW dissipation is required and SOD-123 footprint is acceptable. |
Compared with BZX284-C2V7,115 and MMSZ4678T1G, the BZX284-B2V7,115 uniquely balances ±2% precision, SOD110 miniaturization, and industrial-grade ceramic reliability - making it optimal for space-limited, calibrated analog systems where voltage accuracy and thermal stability are prioritized over raw power handling.

FAQ
What is the Zener voltage tolerance of the BZX284-B2V7,115?
The BZX284-B2V7,115 has a ±2% Zener voltage tolerance, meaning its nominal 2.7 V breakdown voltage is guaranteed between 2.65 V and 2.75 V when tested at 5 mA reverse current. This tighter tolerance distinguishes it from the ±5% BZX284-C2V7,115 variant and supports higher-accuracy reference designs where calibration headroom is limited. The BZX284-B2V7,115 achieves this via tighter process control during wafer fabrication and binning.
Can the BZX284-B2V7,115 be used in place of a 3.3 V Zener diode?
No - the BZX284-B2V7,115 is specified for 2.7 V nominal Zener voltage and cannot regulate at 3.3 V. Attempting to force 3.3 V across it will result in excessive current and thermal failure due to its low differential resistance and 400 mW power limit. For 3.3 V regulation, use BZX284-B3V3,115 (2.4%–3.37 V) or BZX284-B3V6,115 (3.53–3.67 V). The BZX284-B2V7,115 must be applied only within its validated 2.65–2.75 V operating window.
What is the maximum reverse leakage current for the BZX284-B2V7,115?
The maximum reverse leakage current for the BZX284-B2V7,115 is 20 μA at 1 V reverse bias and 25 °C ambient temperature. This value is confirmed in the Electrical Characteristics table of the NXP datasheet and reflects worst-case leakage under light reverse bias - critical for ultra-low-power sensor biasing where nanoampere-level currents affect measurement integrity. The BZX284-B2V7,115 maintains this spec across its full production lot.
Does the BZX284-B2V7,115 have a specified forward voltage?
Yes - the BZX284-B2V7,115 has a forward voltage of 0.9 V maximum at 10 mA forward current and 1.1 V maximum at 100 mA, per the Electrical Characteristics table. These values define its behavior when inadvertently forward-biased, such as during power-up sequencing or fault conditions. Designers must ensure forward current remains below 250 mA continuous rating to avoid damage. The BZX284-B2V7,115's forward characteristics are consistent with standard silicon PN junction diodes.
Is the SOD110 package of the BZX284-B2V7,115 lead-free and RoHS compliant?
Yes - the BZX284-B2V7,115 uses a lead-free, RoHS-compliant SOD110 ceramic package, as confirmed by NXP's product compliance documentation and material declarations. The device meets EU Directive 2011/65/EU and is suitable for consumer, industrial, and medical electronics where hazardous substance restrictions apply. The BZX284-B2V7,115 carries no exemptions and requires no special reflow profile beyond standard Pb-free soldering guidelines.
