Product details
Overview
BZT52H-B6V8,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, designed for precision voltage regulation and reference applications at 6.8 V nominal breakdown voltage with 8 Ω differential resistance at IZ = 5 mA and 830 mW total power dissipation at Tamb ≤ 25 °C. It serves as a stable shunt voltage reference in low-power analog circuits, power supply feedback paths, and overvoltage protection clamping networks.
For engineers reviewing the BZT52H-B6V8,115 datasheet, BZT52H-B6V8,115 pinout, BZT52H-B6V8,115 application, or BZT52H-B6V8,115 equivalent, this part supports design verification of 6.8 V reference stability, thermal derating under PCB copper constraints, reverse leakage behavior at VR < 6.4 V, and compatibility with reflow-soldered SMD layouts using standard SOD123F footprints.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a tightly controlled 6.66 V to 6.94 V working voltage range (±2 %) at IZ = 5 mA, exhibiting a positive temperature coefficient of +1.2 mV/K to +4.5 mV/K across operating current. Its low 8 Ω typical differential resistance ensures minimal output voltage variation under load current shifts.
The device uses planar epitaxial construction for stable long-term Zener voltage drift and low noise performance. Thermal resistance from junction to solder point is 150 K/W, enabling reliable operation up to 150 °C junction temperature when mounted on FR4 PCB with 1 cm² cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 6.66 V to 6.94 V at IZ = 5 mA - defines regulated output voltage window under nominal test conditions |
| Differential Resistance rdif | 8 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current IR | 2 μA max at VR = 5.0 V - specifies leakage level below knee voltage, critical for low-power standby circuits |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad - sets maximum continuous DC power handling before thermal derating |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines conduction loss during forward bias, relevant for polarity protection use cases |
| Junction Temperature Tj | −65 °C to +150 °C - establishes operational envelope for industrial ambient environments |
| Package | SOD123F - compact 2-lead surface-mount plastic package with standardized reflow footprint per Fig. 12 |
Pinout & Package
SOD123F is a small-outline diode package with flat leads, 3.4–3.6 mm length, 2.5–2.7 mm width, and 0.70–0.55 mm height. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; carries reverse breakdown current; marked by bar on package top |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation accuracy than ±5 % variants, reducing need for post-regulation trimming in precision references |
| 830 mW power rating | Supports higher current regulation (up to ~120 mA at 6.8 V) without external heatsinking on standard FR4 PCB |
| Low 8 Ω differential resistance | Minimizes output voltage shift under ±10 mA load transients, improving stability in feedback loops |
| Positive temperature coefficient (+1.2 to +4.5 mV/K) | Compensates for negative TC of other components (e.g., BJTs), enabling stable composite reference designs |
| SOD123F reflow-compatible footprint | Matches IPC-7351B standard for automated assembly; eliminates lead-forming and reduces placement misalignment risk |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Regulating output voltage of isolated DC-DC converters via optocoupler feedback loop. IC Role / Device Role / Timing Role: Provides precise 6.8 V reference to TL431-like shunt regulator IC input, setting feedback threshold.

Use Value: +1.2 to +4.5 mV/K temperature coefficient offsets transistor VBE drift, improving current stability over temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-C6V8 | ±5 % tolerance (6.4–7.2 V), 8 Ω rdif, same SOD123F package | Higher VZ spread increases output uncertainty; suitable only where ±5 % regulation is acceptable | Select for cost-sensitive designs where tighter voltage control is unnecessary and BOM simplification is prioritized |
| MMSZ5234B-7-F | ±5 % tolerance (6.46–7.14 V), 10 Ω rdif, SOD-123 package (mechanically identical) | Higher differential resistance degrades load regulation; slightly lower Ptot (500 mW) | Choose when legacy MMSZ-series qualification or dual-sourcing across Diodes Inc./Nexperia is required |
Compared with BZT52H-B6V8,115, the C6V8 variant trades voltage accuracy for broader tolerance acceptance, while MMSZ5234B-7-F offers cross-manufacturer compatibility at the cost of reduced power handling and regulation stiffness.

FAQ
What is the maximum continuous reverse current this Zener can handle at 6.8 V?
The BZT52H-B6V8,115 is rated for 830 mW total power dissipation at Tamb ≤ 25 °C. At 6.8 V, this corresponds to a maximum continuous reverse current of approximately 122 mA (830 mW ÷ 6.8 V). Derating is required above 25 °C ambient per the 150 K/W junction-to-solder-point thermal resistance.
Does this part meet automotive AEC-Q200 requirements?
No. The BZT52H-B6V8,115 is explicitly designated as non-automotive qualified per Nexperia's revision history (Rev. 7, Jan 2023). It lacks AEC-Q200 stress testing and qualification. For automotive applications, Nexperia offers separate -Q qualified variants such as BZT52H-B6V8-Q.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
At IZ = 5 mA, the BZT52H-B6V8,115 exhibits a temperature coefficient of +1.2 to +4.5 mV/K. Over −40 °C to +85 °C (ΔT = 125 K), this introduces a VZ shift of +0.15 V to +0.56 V. Combined with ±2 % initial tolerance, total regulation error remains within ±3.5 % across this range.
Can this Zener be used in forward-bias mode as a regular diode?
Yes. With a maximum forward voltage of 0.9 V at 10 mA, it functions as a low-leakage silicon diode. However, its 250 mA absolute maximum forward current rating and lack of specified soft recovery make it unsuitable for high-speed switching; it is optimized for reverse-bias regulation, not rectification.
