Product details
Overview
BZT52-C6V8X from Nexperia is a Zener voltage regulator diode in SOD123 surface-mount package, designed for precision low-power voltage reference and clamping in biasing, protection, and regulation circuits. It delivers a nominal 6.8 V Zener voltage at 5 mA, ±5 % tolerance, 8 Ω differential resistance, and supports up to 590 mW total power dissipation at 25 °C ambient.
For engineers reviewing the BZT52-C6V8X datasheet, BZT52-C6V8X pinout, BZT52-C6V8X application, or BZT52-C6V8X equivalent, key selection considerations include its 6.4–7.2 V working range at IZ = 5 mA, low 8 Ω dynamic impedance, cathode-marked SOD123 footprint, and suitability for space-constrained DC bias networks and overvoltage clamp stages.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 6.8 V (min 6.4 V, max 7.2 V) at IZ = 5 mA, exhibiting a positive temperature coefficient of +1.2 to +4.5 mV/K. Its low 8 Ω differential resistance ensures stable regulation under small-signal load variations.
The device uses planar epitaxial construction for repeatable breakdown characteristics and integrates a cathode-indicating marking bar on the SOD123 body. Thermal resistance from junction to solder point is 55 K/W, enabling reliable operation up to 150 °C junction temperature when mounted per specified PCB pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.8 V nominal at IZ = 5 mA; actual range 6.4–7.2 V defines usable regulation window in feedback or reference paths |
| Tolerance | ±5 %; enables cost-optimized selection where tight voltage accuracy is not critical, e.g., non-precision biasing |
| Differential Resistance rdif | 8 Ω max at IZ = 5 mA; determines output impedance and load regulation error in shunt regulator topologies |
| Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C; sets maximum continuous DC or pulsed power handling on standard FR4 PCB |
| Reverse Current IR | 2 μA max at VR = 4.5 V; defines leakage-induced error in high-impedance reference nodes |
| Forward Voltage VF | 0.9 V max at IF = 10 mA; relevant for polarity-sensitive ESD protection or series forward-path use |
| Junction Temperature | 150 °C max; constrains thermal design margin in enclosed or high-ambient environments |
Pinout & Package
Package: SOD123 - compact surface-mount plastic package with 2 leads, 2.80 mm length, 1.70 mm width, and 1.30 mm height; cathode identified by a visible marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node in shunt configuration; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low Differential Resistance | 8 Ω max ensures minimal voltage shift under ±1 mA load current variation in reference circuits |
| Stable Temperature Coefficient | +1.2 to +4.5 mV/K enables predictable VZ drift in ambient ranges up to 125 °C |
| SOD123 Footprint Compatibility | Standardized 2.8 × 1.7 mm outline supports automated placement and reflow on high-density PCBs |
| High Surge Withstand | Non-repetitive peak reverse power of 40 W (100 μs pulse) allows transient overvoltage clamping without failure |
| Low Reverse Leakage | ≤2 μA at 4.5 V enables use in microamp-level bias networks without significant current error |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 6.8 V reference for op-amp comparators or ADC bias in low-power sensor interfaces. IC Role / Device Role / Timing Role: Shunt voltage reference establishing precise threshold voltage independent of supply ripple. Use Value: 8 Ω rdif limits reference deviation to <±8 mV under 1 mA load change, improving measurement repeatability. |
Use Scenario: Protecting microcontroller I/O pins from ESD or inductive kickback in industrial control modules. IC Role / Device Role / Timing Role: Fast-acting clamping element diverting transient energy above 6.8 V to ground before IC damage occurs. Use Value: 40 W non-repetitive surge rating absorbs 100 μs transients without degradation, extending system field life. |
| DC Bias Network | Signal Level Shifting |
Use Scenario: Setting quiescent operating point for discrete transistor amplifiers in audio front-ends. IC Role / Device Role / Timing Role: Fixed-voltage sink establishing emitter or gate bias voltage in Class-A amplifier stages. Use Value: ±5 % VZ tolerance ensures consistent gain and linearity across production batches without calibration. |
Use Scenario: Translating 3.3 V logic signals to 5 V compatible levels in mixed-voltage FPGA interface designs. IC Role / Device Role / Timing Role: Cathode-connected clamp limiting signal swing to 6.8 V while allowing forward conduction below 0.9 V. Use Value: 0.9 V forward drop enables clean low-threshold signal blocking, preserving rise/fall time integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235BS-7-F (Diodes Inc.) | VZ = 6.8 V ±5 %, SOD-323 package, 200 mW Ptot, rdif = 10 Ω | Lower power rating and smaller footprint limit thermal robustness in sustained clamp duty | Select when board area is constrained and average power <150 mW |
| BZX384-C6V8 (Nexperia) | VZ = 6.8 V ±5 %, SOD-323 package, 300 mW Ptot, rdif = 15 Ω | Higher rdif degrades regulation accuracy; same marking and qualification level as BZT52-C6V8X | Choose only if SOD-323 footprint is mandatory and 15 Ω impedance is acceptable |
Compared with MMBZ5235BS-7-F and BZX384-C6V8, BZT52-C6V8X provides superior thermal capability (590 mW vs ≤300 mW) and tighter dynamic impedance (8 Ω vs ≥10 Ω), making it preferred for higher-duty-cycle regulation and precision clamping where SOD123 real estate is available.

FAQ
What is the Zener test current for BZT52-C6V8X?
The rated Zener voltage of 6.8 V is specified at a test current of 5 mA, as defined in Table 8 of the Nexperia datasheet. This current establishes the operating point for measuring VZ, differential resistance, and temperature coefficient under standard conditions (Tj = 25 °C).
Can BZT52-C6V8X be used in automotive applications?
No - BZT52-C6V8X is explicitly designated as non-automotive qualified per Nexperia's revision history. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing; use only in industrial, consumer, or commercial systems.
How does the SOD123 package affect thermal performance?
The SOD123 package achieves a junction-to-solder-point thermal resistance of 55 K/W when mounted per Nexperia's recommended 1 cm² cathode pad. This enables safe operation at full 590 mW dissipation only with adequate copper area; derating is required on minimal pads.
What is the meaning of the 'C' in BZT52-C6V8X?
The 'C' denotes the ±5 % tolerance grade within the BZT52 series, distinguishing it from the tighter ±2 % 'B' grade. The 'X' suffix indicates tape-and-reel packaging per standard ordering code conventions used by Nexperia for SMD components.
