Product details
Overview
BZV90-C6V8,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers nominal 6.8 V regulation at 5 mA test current, with ±5% tolerance, 6–15 Ω differential resistance, and +1.2 to +4.5 mV/K temperature coefficient. Used in industrial power supervisors and analog sensor biasing circuits.
For engineers reviewing the BZV90-C6V8,115 datasheet, BZV90-C6V8,115 pinout, BZV90-C6V8,115 application, or BZV90-C6V8,115 equivalent, key selection criteria include Zener voltage accuracy at IZtest = 5 mA, thermal coefficient behavior across −65 °C to +150 °C, peak surge capability (40 W, 100 μs), and SOT223 thermal resistance (83.3 K/W).
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 6.4–7.2 V at IZ = 5 mA, exhibiting low dynamic impedance (6–15 Ω) and positive temperature coefficient (+1.2 to +4.5 mV/K) typical of mid-voltage Zeners. Its SOT223 package integrates a large copper collector pad for enhanced thermal dissipation.
It supports non-repetitive surge handling up to 40 W for 100 μs pulses and maintains stable regulation under continuous 1.5 W power dissipation when mounted on 2 cm² FR4 PCB copper area. Reverse leakage remains ≤2 μA at VR = 4.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ @ IZtest | 6.4–7.2 V at 5 mA - defines usable regulation window for 5 V–12 V rail stabilization |
| rdif | 6–15 Ω - determines output impedance and load regulation error under varying current |
| SZ | +1.2 to +4.5 mV/K - quantifies voltage drift over temperature; enables compensation design |
| Ptot | 1500 mW - maximum continuous power at Tamb = 25 °C on 2 cm² FR4 board |
| PZSM | 40 W (100 μs) - defines transient overvoltage clamping capability without failure |
| Cd | 200 pF @ 1 MHz, VR = 0 V - impacts high-frequency noise filtering and stability in feedback paths |
| IR @ VR | ≤2 μA @ 4.0 V - ensures minimal quiescent current draw in low-power standby circuits |
Pinout & Package
SOT223 plastic surface-mount package with integrated copper thermal pad; 4-lead configuration optimized for PCB heat spreading and mechanical robustness in automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main anode connection; tied to lower-potential node in reverse-biased regulation configuration |
| 2, 4 | Cathode | Common cathode terminals; electrically connected - used for high-current return and thermal conduction to PCB |
| 3 | Anode | Secondary anode; internally bonded to Pin 1 - provides redundancy and improved solder joint reliability |
Key Features
| Feature | Design Value |
|---|---|

| Non-repetitive 40 W surge rating | Clamps short-duration transients (e.g., ESD, inductive kick) without degradation |
| SOT223 thermal pad | Reduces Rth j-a to 83.3 K/W - sustains higher average power vs. SOD-123 or DO-35 packages |
| Low 200 pF capacitance | Maintains bandwidth >1 MHz in feedback loops; avoids phase shift in precision references |
| −65 °C to +150 °C operation | Validated for automotive under-hood and industrial motor drive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8 | Same VZ range but SOT23 package; Ptot = 300 mW; rdif = 40 Ω; no thermal pad | Limited to low-power signal-level regulation; unsuitable for >100 mA load or surge events | Select when board space is constrained and thermal load <300 mW; avoid for power rail clamping |
| MMBZ5236B | SOT23; VZ = 6.8 V ±5%; Ptot = 350 mW; rdif = 13 Ω; Tj max = 150 °C | Higher rdif than BZV90-C6V8,115; lacks 40 W surge rating; same temp coefficient profile | Prefer for cost-sensitive consumer designs where surge immunity is not required |
Compared with BZX84-C6V8 and MMBZ5236B, BZV90-C6V8,115 uniquely combines high-power dissipation (1500 mW), robust surge handling (40 W), and low dynamic impedance (6–15 Ω) in a thermally enhanced SOT223 package - making it the only option among the three qualified for industrial power rail regulation and transient protection.

FAQ
What is the maximum continuous power dissipation for BZV90-C6V8,115?
The BZV90-C6V8,115 has a total power dissipation rating of 1500 mW at Tamb = 25 °C when mounted on an FR4 PCB with 2 cm² double-sided copper area. Derating is required above 25 °C at 12 mW/°C based on its 83.3 K/W junction-to-ambient thermal resistance.
Does BZV90-C6V8,115 support surge protection applications?
Yes - it is rated for non-repetitive peak reverse power dissipation of 40 W at pulse width 100 μs, validated per IEC 60134. This enables reliable clamping of inductive switching transients and ESD events without parameter shift, provided PCB layout provides adequate copper thermal mass.
How does the temperature coefficient behave across operating current?
At VZ = 6.8 V, the temperature coefficient SZ ranges from +1.2 to +4.5 mV/K depending on test current (5 mA typical). It increases with higher Zener current and exhibits predictable linear drift between −65 °C and +150 °C, enabling accurate compensation in precision references.
Why does BZV90-C6V8,115 have four pins in SOT223?
Pins 1 and 3 are internally connected anodes; Pins 2 and 4 are internally connected cathodes. This dual-terminal configuration improves solder joint reliability, reduces bond wire stress, and enhances thermal conduction from the cathode to the PCB copper plane - critical for sustained 1.5 W operation.
