Product details
Overview
BZX384-B2V7,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 2.7 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision low-power voltage reference in bias networks, overvoltage clamping, and supply rail stabilization circuits for portable instrumentation and sensor signal conditioning.
For engineers reviewing the BZX384-B2V7,115 datasheet, BZX384-B2V7,115 pinout, BZX384-B2V7,115 application, or BZX384-B2V7,115 equivalent, key selection criteria include its 2.7 V ±2 % Zener voltage tolerance, 600 Ω maximum differential resistance at 5 mA, 20 μA reverse current at 1 V, -3.5 to 0.0 mV/K temperature coefficient, and thermal resistance of 415 K/W junction-to-ambient.
Technical Context
This device operates in reverse-biased Zener breakdown mode with a specified 2.7 V working voltage at IZ = 5 mA. Its differential resistance of ≤600 Ω ensures stable regulation under small-signal load variations, while the -3.5 to 0.0 mV/K temperature coefficient indicates negative or near-zero drift across 25–150 °C.
The SOD323 package enables compact PCB layout with defined thermal performance: Rth(j-a) = 415 K/W in free air and Rth(j-sp) = 110 K/W to solder point. Non-repetitive surge capability supports transient suppression up to 40 W for 100 μs pulses at Tj = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 2.65 V to 2.75 V at IZ = 5 mA - defines tight ±2 % regulation window for low-voltage reference stability |
| Power dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential resistance (rdif) | ≤600 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse current (IR) | ≤20 μA at VR = 1 V - specifies leakage level below breakdown, critical for low-power standby circuits |
| Temperature coefficient (SZ) | -3.5 to 0.0 mV/K at IZ = 5 mA - quantifies voltage drift vs. junction temperature, enabling thermal error budgeting |
| Non-repetitive peak power (PZSM) | 40 W for tp = 100 μs - supports short-duration ESD or surge clamping without failure |
| Forward voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
Pinout & Package
The BZX384-B2V7,115 is housed in a surface-mount SOD323 (SC-76) plastic package with cathode-marked top-side bar. The two-terminal configuration supports bidirectional mounting verification via visible marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in Zener regulation; marked by bar on package top |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); establishes reverse-bias polarity |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation than ±5 % variants (BZX384-C), reducing calibration overhead in precision analog stages |
| 300 mW total power rating | Supports continuous operation in space-constrained, low-power applications without forced cooling |
| 40 W non-repetitive peak power | Provides robust transient immunity against ESD events per IEC 61000-4-2 Level 4 without external TVS |
| SOD323 footprint compatibility | Matches industry-standard 2.3 × 1.35 mm land pattern (JEDEC MO-203AA), ensuring drop-in replacement in existing layouts |
| 150 °C maximum junction temperature | Allows reliable operation in high-ambient environments such as automotive cabin electronics or industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-A2V7 | ±1 % tolerance (2.67–2.73 V), lower rdif (≤600 Ω), same Ptot | Higher precision required in metrology-grade references where 0.5 % additional tolerance margin is unacceptable | Select when absolute voltage accuracy dominates over cost; requires tighter layout control due to reduced process spread |
| BZX384-C2V7 | ±5 % tolerance (2.50–2.90 V), higher rdif (≤600 Ω), same Ptot | Cost-driven consumer electronics where 2.7 V nominal is sufficient and calibration is performed post-assembly | Select for high-volume, non-critical biasing where 10× cost reduction justifies wider voltage spread and higher tempco uncertainty |
Compared with BZX384-A2V7, the BZX384-B2V7,115 trades 0.5 % tolerance for broader process yield and lower unit cost, while versus BZX384-C2V7 it delivers twice the voltage accuracy and more predictable thermal drift-making it optimal for mid-tier industrial and medical sensing designs.

FAQ
What is the maximum continuous reverse current this diode can handle?
The BZX384-B2V7,115 has no specified maximum continuous reverse current; instead, its safe operating limit is defined by power dissipation. At 25 °C ambient on standard FR4 PCB, it sustains ≤300 mW, corresponding to ~111 mA at 2.7 V. Derating applies above 25 °C per the 415 K/W thermal resistance.
Can this Zener be used in forward conduction mode?
Yes-the device exhibits ≤0.9 V forward voltage at 10 mA, making it suitable for low-loss polarity protection or LED current-limiting functions. However, its primary design intent and characterization are for reverse-biased Zener operation; forward parameters are secondary specifications.
How does the -3.5 to 0.0 mV/K temperature coefficient affect circuit performance?
This coefficient means the Zener voltage decreases by up to 3.5 mV per Kelvin rise in junction temperature-or remains nearly flat near zero. In a 2.7 V reference, that translates to ≤0.54 V drift over a 150 °C range, but typical use within -40 to +85 °C yields <0.34 V variation, requiring compensation only in sub-0.1 % accuracy systems.
Is the SOD323 package compatible with standard reflow profiles?
Yes-the SOD323 outline complies with JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 30 s). Nexperia provides dedicated footprint dimensions (2.2 × 1.15 mm solder lands) and recommends 0.5 mm pad spacing for reliable tombstoning prevention.
