Product details
Overview
BZT52-C6V2X from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 6.2 V nominal regulation at 5 mA, with 150 Ω max differential resistance and 3 μA max reverse current at 4.7 V, used for precision voltage reference and low-power rail clamping in consumer power management circuits.
For engineers reviewing the BZT52-C6V2X datasheet, BZT52-C6V2X pinout, BZT52-C6V2X application, or BZT52-C6V2X equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance data, and direct-fit alternatives for board-level voltage stabilization design.
Technical Context
This Zener operates in reverse breakdown mode with a temperature coefficient of +0.4 to +3.7 mV/K at IZ = 5 mA, enabling stable regulation across -55 °C to +150 °C ambient. Its low 150 Ω differential resistance ensures minimal output voltage shift under load variation.
The device uses silicon planar epitaxial construction and is qualified per industrial reliability standards. It is not automotive-qualified and must be mounted on FR4 PCB with specified 1 cm² cathode pad for rated 590 mW power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.8 V to 6.6 V at IZ = 5 mA - defines regulation band for 6.2 V nominal rail |
| Differential Resistance rdif | 150 Ω max - limits voltage deviation under ±1 mA current change |
| Reverse Current IR | 3 μA max at VR = 4.7 V - ensures low standby leakage in bias networks |
| Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets thermal layout requirement |
| Thermal Resistance Rth(j-sp) | 55 K/W - quantifies junction-to-solder-point heat transfer efficiency |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - constrains forward conduction loss in protection paths |
| Junction Temperature Tj | 150 °C max - determines maximum allowable power under derating curves |

Applications
| USB Port Overvoltage Clamp | Microcontroller Reset Circuit Reference |
|---|---|
|
Use Scenario: Clamps USB VBUS transients above 6.2 V to protect downstream 3.3 V logic. IC Role / Device Role / Timing Role: Zener acts as shunt regulator in parallel with TVS, conducting only when VBUS exceeds 6.2 V. Use Value: Limits peak clamping voltage to 6.6 V (max VZ) while drawing < 1 mA at 5.5 V, minimizing standby loading. |
Use Scenario: Provides stable 6.2 V reference for RC-based reset timing in MCU power-up sequencing. IC Role / Device Role / Timing Role: Functions as precision voltage threshold detector feeding comparator input. Use Value: ±5 % tolerance and +0.4 mV/K tempco ensure reset window remains within 10 ms accuracy over −40 °C to +85 °C. |
| Low-Power Sensor Bias Supply | Industrial Analog Input Protection |
|
Use Scenario: Generates clean 6.2 V bias for analog front-end op-amps in battery-powered sensors. IC Role / Device Role / Timing Role: Zener supplies regulated excitation voltage to bridge sensors or reference buffers. Use Value: 3 μA max IR at 4.7 V enables operation from 10 μA current sources with < 0.5 % error contribution. |
Use Scenario: Protects 0–10 V analog input stages from field-induced surges in PLC modules. IC Role / Device Role / Timing Role: Shunt limiter placed before series resistor and input amplifier. Use Value: 150 Ω rdif ensures clamp voltage stays below 6.8 V even during 2 mA fault current, preserving ADC input integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5230BS-7-F (Diodes Inc.) | Same 6.2 V nominal, ±5 %, SOD-323 package, 200 mW Ptot, 200 Ω rdif | Lower power rating requires derating above 70 °C ambient; smaller footprint reduces thermal mass | Select when board space is constrained and thermal load is < 150 mW |
| BZX384-C6V2 (Nexperia) | Same 6.2 V, ±5 %, but SOD-323 package, 300 mW Ptot, 150 Ω rdif, automotive-qualified (-Q option available) | Higher reliability screening and AEC-Q200 qualification support safety-critical subsystems | Select for automotive or industrial systems requiring extended qualification and traceability |
Compared with BZT52-C6V2X, MMBZ5230BS-7-F trades thermal robustness for miniaturization, while BZX384-C6V2 offers identical electrical performance with enhanced process control and qualification-making it suitable where reliability certification outweighs cost sensitivity.

FAQ
What is the maximum continuous reverse current the BZT52-C6V2X can handle at 25 °C?
The device supports up to 250 mA forward current, but its Zener operation is defined at test currents of 1–5 mA. Continuous reverse conduction beyond 5 mA requires thermal validation: at 25 °C ambient and proper PCB pad, it sustains 5 mA indefinitely; higher currents demand derating per the 590 mW total power limit and 55 K/W junction-to-solder-point thermal resistance.
How does the cathode marking appear on the BZT52-C6V2X package?
The cathode is marked by a distinct color band (typically black or dark gray) aligned with Pin 1 on the SOD123 body. Per Nexperia's marking table, BZT52-C6V2X uses "CB" code, printed adjacent to the band. The band corresponds to the simplified outline's "K" terminal in the official pinning diagram.
Can BZT52-C6V2X replace BZT52-B6V2 in an existing design?
Yes, but with trade-offs: BZT52-C6V2X has ±5 % tolerance versus BZT52-B6V2's tighter ±2 %, and its differential resistance is 150 Ω vs. 100 Ω for the B-series. If the application relies on tight voltage accuracy or low dynamic impedance, revalidation of regulation error under load is required.
Is BZT52-C6V2X suitable for automotive applications?
No. This part is explicitly labeled "non-automotive qualified" in the revision history. It lacks AEC-Q200 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the BZX384-C6V2-Q series, which shares identical electrical specs but includes full automotive qualification and traceability.
