Product details
Overview
BZX384-C6V2/ZLX from Nexperia is a 6.2 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 150 Ω typical differential resistance at IZ = 5 mA and <3 μA reverse current at VR = 4 V, used for low-power voltage reference and overvoltage protection in consumer power rails.
For engineers reviewing the BZX384-C6V2/ZLX datasheet, BZX384-C6V2/ZLX pinout, BZX384-C6V2/ZLX application, or BZX384-C6V2/ZLX equivalent, key selection criteria include its ±5 % tolerance band, 150 °C maximum junction temperature, 150 Ω dynamic impedance, non-repetitive 40 W surge capability, and cathode-marked SOD323 footprint compatibility with standard reflow profiles.
Technical Context
This device operates as a two-terminal silicon Zener diode, conducting in reverse breakdown to maintain stable 6.2 V across its terminals under controlled current conditions. Its regulation relies on avalanche and Zener mechanisms depending on voltage level, with temperature coefficient of +0.4 mV/K at IZ = 5 mA - indicating positive drift with rising temperature.
Designed for low-power linear regulation and clamping, it features 200 pF capacitance at 0 V and 1 MHz, 110 K/W thermal resistance from junction to solder point, and supports forward conduction up to 250 mA - enabling bidirectional transient suppression when paired with series components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.2 V nominal, ±5 % tolerance (5.8 V to 6.6 V), specified at IZ = 5 mA - defines stable regulation window for precision reference use |
| Differential Resistance | 150 Ω max at IZ = 5 mA - determines output voltage deviation under load current changes |
| Reverse Current | <3 μA at VR = 4 V - ensures minimal leakage in standby or high-impedance bias networks |
| Total Power Dissipation | 300 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling without derating |
| Non-repetitive Peak Power | 40 W for tp ≤ 100 μs - enables short-duration surge suppression in ESD or inductive kick scenarios |
| Junction Temperature | 150 °C max - constrains thermal design margin when mounted on standard PCB layouts |
| Package | SOD323 (SC-76) - 2-pin surface-mount outline with 1.35 mm × 0.85 mm body and cathode bar marking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2 | ±2 % tolerance (6.08 V–6.32 V), 80 Ω max rdif at IZ = 5 mA | Tighter regulation needed for precision references; higher cost | Select when voltage stability over temperature and current is critical, e.g., ADC reference buffers |
| MMBZ5234B | 6.2 V ±5 %, SOT-23 package, 350 mW rating, 170 Ω max rdif | Larger footprint, higher thermal resistance (Rth(j-a) = 450 K/W), different marking | Choose if existing SOT-23 layout exists or higher power margin is required despite larger board area |
Compared with BZX384-C6V2/ZLX, BZX384-B6V2 offers tighter tolerance and lower impedance but at higher unit cost and identical SOD323 footprint, while MMBZ5234B trades compactness for slightly higher power rating and less favorable thermal performance in dense layouts.

FAQ
What is the exact breakdown voltage range for BZX384-C6V2/ZLX?
The BZX384-C6V2/ZLX has a nominal Zener voltage of 6.2 V with ±5 % tolerance, resulting in a guaranteed breakdown range of 5.8 V to 6.6 V when tested at IZ = 5 mA and Tj = 25 °C. This range reflects the C-series tolerance grade and is validated per Nexperia's Product Data Sheet Rev. 4.
Does BZX384-C6V2/ZLX support surge protection applications?
Yes, BZX384-C6V2/ZLX supports non-repetitive surge suppression with a peak reverse power dissipation rating of 40 W for pulse durations ≤100 μs. Its ability to clamp transients up to this limit makes it suitable for ESD protection and inductive load flyback suppression when used with appropriate series impedance.
What is the thermal resistance from junction to solder point for BZX384-C6V2/ZLX?
The thermal resistance from junction to solder point (Rth(j-sp)) for BZX384-C6V2/ZLX is 110 K/W, measured at the cathode tab. This value enables accurate thermal modeling when the device is mounted on standard FR4 PCBs with tin-plated copper, supporting reliability analysis in thermally constrained designs.
Can BZX384-C6V2/ZLX be used in place of a 5.1 V Zener diode?
No - BZX384-C6V2/ZLX is specifically rated for 6.2 V breakdown and is not a functional substitute for a 5.1 V Zener like BZX384-C5V1. Substitution would result in incorrect regulation voltage and potential system malfunction; always match nominal Zener voltage and tolerance grade to circuit requirements.
What marking code identifies BZX384-C6V2/ZLX on the device body?
BZX384-C6V2/ZLX is marked with the code "T1" on its top surface, as confirmed in Table 4 of the Nexperia datasheet. The marking appears adjacent to the cathode bar, which serves as the polarity indicator for correct PCB orientation during placement.
