Product details
Overview
BZX384-B6V2,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 6.2 V nominal breakdown at 5 mA, with 150 Ω typical differential resistance and ≤300 mW total power dissipation. It provides stable reference voltage in low-power analog circuits, such as sensor biasing, voltage clamping in microcontroller I/O protection, and precision threshold detection in battery-powered IoT nodes.
For engineers reviewing the BZX384-B6V2,115 datasheet, BZX384-B6V2,115 pinout, BZX384-B6V2,115 application, or BZX384-B6V2,115 equivalent, this page delivers verified Zener voltage, thermal resistance, reverse current limits, temperature coefficient, and SOD323 footprint compatibility - all critical for ESD-tolerant, space-constrained board designs.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 6.2 V reference across load variations and temperature shifts from −65 °C to +150 °C. Its 0.4 mV/K temperature coefficient at 5 mA ensures minimal drift in mid-range voltage regulation applications.
The device features non-repetitive peak reverse power dissipation of 40 W (100 μs pulse), 150 Ω max differential resistance at IZ = 5 mA, and reverse current ≤3 μA at VR = 4.96 V - enabling reliable overvoltage clamping without thermal runaway under transient stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - defines tight regulation window for precision reference use |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤3 μA at VR = 4.96 V - ensures low leakage in standby and battery-sensitive circuits |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Thermal Resistance (Rth(j-a)) | 415 K/W - indicates junction-to-ambient heat transfer efficiency in free-air mounting |
| Temperature Coefficient (SZ) | +0.4 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs pulse - supports transient surge suppression without failure |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.35 mm × 0.85 mm body, 0.45 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; accepts reverse bias voltage; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation than ±5 % variants, reducing need for post-regulation trimming in feedback loops |
| Low 150 Ω dynamic impedance | Minimizes output voltage variation under changing load current, improving stability in active bias networks |
| 415 K/W junction-to-ambient thermal resistance | Allows safe operation up to 150 °C junction temperature with minimal heatsinking in compact layouts |
| 40 W non-repetitive peak power rating | Withstands ESD transients (IEC 61000-4-2 Level 4) without degradation when used in I/O protection |
| SOD323 footprint compatibility | Matches standard 0805-equivalent land pattern (2.2 mm × 1.35 mm), easing layout reuse across Nexperia Zener families |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | 6.2 V ±5 %, SOT-323 package, 200 mW Ptot, 170 Ω rdif | Higher power derating above 70 °C; less stable under pulsed loads | Select when cost sensitivity outweighs regulation precision and thermal margin |
| BZX384-C6V2,115 | 6.2 V ±5 %, identical SOD323 package, same Ptot and Rth(j-a) | Looser tolerance increases reference uncertainty but improves yield in high-volume consumer designs | Choose for non-critical biasing where ±5 % VZ meets system error budget |
Compared with BZX384-B6V2,115, MMBZ5234BS-7-F trades voltage accuracy for broader availability and lower unit cost, while BZX384-C6V2,115 retains identical thermal and packaging behavior but relaxes tolerance to reduce manufacturing test overhead - making both suitable only where 6.2 V stability requirements are relaxed beyond ±2 %.

FAQ
What is the maximum continuous reverse current this diode can handle at 25 °C ambient?
The BZX384-B6V2,115 is rated for continuous operation at up to 250 mA forward current, but as a Zener regulator it is reverse-biased; its maximum steady-state reverse current is determined by power dissipation. At 25 °C ambient on FR4 PCB, 300 mW / 6.2 V ≈ 48 mA is the practical upper limit for continuous Zener conduction without exceeding thermal limits.
Does this part have automotive qualification?
No. The BZX384-B6V2,115 is not automotive-qualified. Per Nexperia's revision history (Rev. 4, Jan 2023), the BZX384 series was explicitly changed to non-automotive qualification; automotive alternatives are designated with "-Q" suffix and require separate selection from Nexperia's qualified portfolio.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a measured +0.4 mV/K temperature coefficient at 5 mA, the BZX384-B6V2,115 exhibits approximately +20 mV drift over a 50 K range. This translates to ±0.32 % change in 6.2 V nominal output, which remains within the ±2 % initial tolerance band and supports stable performance in commercial-grade industrial environments.
Can this Zener diode replace a 6.2 V TL431-based shunt regulator?
No - the BZX384-B6V2,115 lacks the active feedback, adjustable output, and current-sink capability of the TL431. It serves only as a passive two-terminal shunt reference. For applications requiring programmable thresholds, dynamic load regulation, or >100 mA sink current, a TL431 or similar IC regulator is necessary; this Zener is appropriate only for fixed-voltage, low-current (<50 mA) biasing or clamping.
