Product details
Overview
BZX384-B62,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 6.2 V nominal breakdown voltage at 5 mA, with 150 Ω typical differential resistance and ≤300 mW total power dissipation. It operates across –65 °C to +150 °C ambient and serves as a precision reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX384-B62,115 datasheet, BZX384-B62,115 pinout, BZX384-B62,115 application, or BZX384-B62,115 equivalent, this page delivers verified electrical parameters, thermal behavior, cathode/anode terminal mapping, real-world regulation use cases, and validated alternative parts for design flexibility and supply continuity.
Technical Context
This Zener diode functions as a two-terminal shunt voltage reference, maintaining stable reverse-biased conduction above its 6.2 V breakdown threshold with temperature coefficient of +0.4 mV/K at IZ = 5 mA. Its low 150 Ω differential resistance ensures minimal output voltage variation under load current shifts.
Designed for surface-mount operation on FR4 PCBs with single-sided copper, it supports non-repetitive surge handling up to 40 W (100 μs pulse) and exhibits 200 pF junction capacitance at 0 V reverse bias-critical for noise-sensitive biasing and filtering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 6.08 V to 6.32 V at IZ = 5 mA - defines precise regulation window for 6.2 V nominal reference |
| Differential Resistance rdif | 150 Ω max - determines output impedance and load regulation error sensitivity |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Non-repetitive Peak Power | 40 W for 100 μs - enables transient overvoltage clamping without failure |
| Reverse Current IR | ≤3 μA at VR = 4 V - ensures low leakage in standby or high-impedance bias networks |
| Temperature Coefficient SZ | +0.4 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal stability analysis |
| Junction-to-Ambient Rth(j-a) | 415 K/W - establishes thermal rise per watt in free-air mounting conditions |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-pin, small outline, cathode-marked with bar; dimensions 1.8 mm × 1.35 mm × 0.95 mm (L × W × H), compatible with reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode reference point for voltage clamping |
| 2 | Anode (A) | Connected to circuit ground or lower potential; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % voltage tolerance | Enables tighter regulation than ±5 % variants, reducing calibration overhead in precision analog stages |
| Low 150 Ω differential resistance | Minimizes output voltage shift under varying load currents, improving reference stability |
| 40 W non-repetitive peak power | Supports robust ESD and surge protection without external components in I/O line clamping |
| 200 pF junction capacitance | Allows integration into high-frequency bias networks without significant signal loading |
| –65 °C to +150 °C operating range | Validates use in industrial and automotive-adjacent environments where extended thermal margins are required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B62,115 (Nexperia) | 6.2 V ±2 %, 150 Ω rdif, SOD323 | Optimized for low-leakage (<3 μA @ 4 V), high-temp operation (150 °C) | Preferred for precision references requiring tight tolerance and wide thermal range |
| MMSZ4687T1G (onsemi) | 6.2 V ±5 %, 200 Ω rdif, SOD123 | Larger package (SOD123), higher leakage (5 μA @ 4 V), lower max Tj (150 °C same) | Select when cost sensitivity outweighs tolerance and leakage requirements; requires footprint redesign |
Compared with MMSZ4687T1G, BZX384-B62,115 offers tighter voltage control and lower dynamic impedance for improved regulation accuracy, while its smaller SOD323 footprint saves board space-making it superior for space-constrained, high-stability analog designs.

FAQ
What is the maximum continuous forward current rating for BZX384-B62,115?
The device is not rated for continuous forward conduction; its primary function is reverse-bias Zener operation. Absolute maximum forward current is 250 mA per limiting values table, but sustained forward bias exceeds design intent and risks thermal runaway. Forward voltage is specified only for test pulses (≤100 μs).
Can BZX384-B62,115 be used in place of a 6.2 V TL431 shunt regulator?
No-it lacks active feedback, adjustable reference, and sink current capability. The TL431 provides programmable 2.5 V reference with 100 mA sink capacity; BZX384-B62,115 is a passive 6.2 V Zener with 5 mA typical operating current and no gain or regulation loop. Use only where simple, low-current clamping suffices.
How does the +0.4 mV/K temperature coefficient affect long-term voltage stability?
At 6.2 V nominal, +0.4 mV/K translates to +0.0065 %/°C drift-so over a 100 °C range (–40 °C to +60 °C), output shifts ~40 mV (0.65 %). This is acceptable for non-critical biasing but insufficient for metrology-grade references; compensation or selection of zero-TC variants (e.g., BZX384-B3V3) may be needed.
Is BZX384-B62,115 qualified for automotive applications?
No-this part is non-automotive qualified per Revision 4 datasheet. Nexperia explicitly states that BZX384-B62,115 is not tested or warranted for automotive use. For AEC-Q101-compliant alternatives, consult Nexperia's BZX384-Q series or dedicated automotive Zener families.
