Product details
Overview
BZX384-C6V8,115 from Nexperia is a 6.8 V ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) surface-mount package, rated for 300 mW total power dissipation at 25 °C ambient, with 80 Ω typical differential resistance at 5 mA and 2 µA maximum reverse current at 5.2 V, used for precision low-power voltage reference and overvoltage protection in compact DC power rails.
For engineers reviewing the BZX384-C6V8,115 datasheet, BZX384-C6V8,115 pinout, BZX384-C6V8,115 application, or BZX384-C6V8,115 equivalent, this page delivers verified Zener voltage, tolerance, thermal resistance, peak surge capability, and cathode/anode terminal mapping - all confirmed from Nexperia's Rev. 4 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 6.8 V regulation across load and line variations, with temperature coefficient of +1.2 mV/K at 5 mA enabling predictable drift compensation in bias networks. Its 110 K/W junction-to-solder-point thermal resistance supports reliable operation on standard FR4 PCBs with single-sided copper.
The device sustains non-repetitive 40 W reverse power surges (100 µs pulse) and handles up to 250 mA forward current, while its 200 pF capacitance at 0 V and 6.4–7.2 V working voltage range (min/max) ensure compatibility with low-noise analog references and transient-clamping circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V nominal; min 6.4 V / max 7.2 V at IZ = 5 mA - defines regulation band for stable reference generation |
| Tolerance | ±5 % - enables cost-effective selection where tight voltage accuracy is not critical |
| Differential Resistance (rdif) | 80 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤2 µA at VR = 5.2 V - ensures minimal leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs pulse - supports transient overvoltage suppression without failure |
| Junction-to-Ambient Rth | 415 K/W in free air - informs derating curves for elevated ambient temperatures |
Pinout & Package
Package: SOD323 (SC-76), 2-pin surface-mount plastic package with cathode marked by bar; dimensions 1.8 mm × 1.35 mm × 0.95 mm (L × W × H), compatible with reflow and wave soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during regulation |
| 2 | Anode (A) | Connected to ground or lower-potential rail - completes Zener conduction path when reverse voltage exceeds VZ |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD package | SOD323 footprint (1.8 × 1.35 mm) enables high-density PCB layouts in space-constrained consumer and industrial modules |
| Controlled Zener tolerance | ±5 % (C-series) balances cost and performance for general-purpose regulation where 6.8 V ±0.34 V is acceptable |
| Thermal robustness | 150 °C max junction temperature and 110 K/W junction-to-solder-point resistance support reliable operation on thermally stressed boards |
| Surge resilience | 40 W non-repetitive peak reverse power (100 µs) allows use in input-stage clamping without external TVS devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5235BLT1G | 6.8 V ±5 %, 350 mW Ptot, SOT-23 package, 100 Ω rdif | Larger footprint (2.9 × 1.3 mm vs. 1.8 × 1.35 mm); higher thermal resistance (500 K/W) | Select when higher power margin is needed and board space permits larger package |
| Vishay BZX384-B6V8,115 | 6.8 V ±2 %, same SOD323 package, 40 Ω rdif, 1 µA IR at 5.2 V | Tighter tolerance improves reference accuracy but increases cost; lower leakage benefits ultra-low-power designs | Select when ±2 % stability is required for precision analog stages or low-leakage biasing |
Compared with BZX384-C6V8,115, the MMBZ5235BLT1G offers higher power headroom but sacrifices board density and thermal efficiency, while the BZX384-B6V8,115 delivers tighter regulation and lower leakage at the expense of cost and availability - making the C-series optimal for cost-sensitive, space-constrained general regulation.

FAQ
What is the maximum continuous reverse voltage this diode can regulate?
The BZX384-C6V8,115 regulates continuously at its nominal Zener voltage of 6.8 V, with guaranteed operation between 6.4 V (min) and 7.2 V (max) at 5 mA test current. It must not be subjected to sustained reverse voltages exceeding 7.2 V without current limiting, as that risks thermal runaway beyond its 300 mW power rating.
Can this Zener diode be used in parallel for higher current handling?
No - parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages and thermal runaway risk. Each BZX384-C6V8,115 must be individually current-limited; for higher current needs, select a higher-power Zener or use an active regulator instead.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +1.2 mV/K temperature coefficient at 5 mA, the BZX384-C6V8,115 exhibits approximately +82 mV drift from 25 °C to 90 °C ambient. This is factored into system-level tolerance budgets for reference circuits and must be compensated in precision applications via external circuitry or calibration.
Is this part suitable for automotive applications?
No - the BZX384-C6V8,115 is not automotive-qualified. Nexperia explicitly states in Revision 4 that BZX384 series products changed to non-automotive qualification in 2023; automotive alternatives require the -Q suffix (e.g., BZX384-C6V8,115-Q) and separate qualification testing.
