Product details
Overview
BZX84-C6V8/DG/B3,2 from Nexperia is a 6.8 V ±5% Zener diode in SOT-23 package, rated for 300 mW power dissipation and 5 mA test current, with 15 Ω dynamic impedance and 100 nA reverse leakage at 4.5 V, used for voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84-C6V8/DG/B3,2 datasheet, BZX84-C6V8/DG/B3,2 pinout, BZX84-C6V8/DG/B3,2 application, or BZX84-C6V8/DG/B3,2 equivalent, key selection criteria include Zener voltage tolerance, power rating, dynamic impedance, reverse leakage, and SOT-23 thermal performance in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and supply conditions. Its 6.8 V nominal Zener voltage is specified at 5 mA test current with ±5% tolerance, and it exhibits 15 Ω dynamic impedance at that bias point.
The device supports continuous DC operation up to 300 mW at 25 °C ambient, derating linearly above 60 °C junction temperature. Reverse leakage remains ≤100 nA at 4.5 V, ensuring minimal quiescent current draw in standby regulation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V ±5% at IZ = 5 mA - defines regulated output voltage with tight tolerance for precision reference use |
| Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum steady-state power handling in SOT-23 footprint |
| Dynamic Impedance (ZZ) | 15 Ω at IZ = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | ≤100 nA at VR = 4.5 V - ensures negligible current draw in undervoltage clamp or bias networks |
| Test Current (IZT) | 5 mA - standard operating point for specifying VZ, ZZ, and temperature coefficient |
| Package | SOT-23 - surface-mount, 3-pin, JEDEC TO-236AB outline enabling high-density PCB layout |
Pinout & Package
SOT-23 package with cathode-marked lead configuration: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC). Standard pinout aligns with JEDEC TO-236AB mechanical drawing and Nexperia's device marking convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Forward conduction terminal | Connected to lower potential side in reverse-biased Zener operation; required for proper polarity in shunt regulation |
| Pin 2 (Cathode) | Reverse breakdown terminal | Connected to higher potential side; carries regulated current during clamping or reference generation |
| Pin 3 (NC) | No internal connection | Electrically isolated; must remain unconnected to avoid parasitic coupling or thermal stress |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables accurate voltage reference without post-production trimming in cost-sensitive consumer and industrial sensors |
| Low 15 Ω dynamic impedance | Minimizes output voltage shift across 1–10 mA load current range in feedback or bias networks |
| 100 nA max reverse leakage at 4.5 V | Reduces standby power loss in battery-powered devices requiring long-term undervoltage hold-off |
| SOT-23 package compatibility | Supports automated pick-and-place assembly and reflow soldering per IPC-J-STD-020 standards |

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The BZX84-C6V8/DG/B3,2 supports up to 44 mA continuous reverse current at 25 °C ambient, calculated from its 300 mW power rating divided by 6.8 V nominal Zener voltage. Derating applies above 60 °C ambient per the datasheet thermal curve.
Does this part meet AEC-Q200 stress testing requirements for automotive use?
No-this variant is not AEC-Q200 qualified. Nexperia offers AEC-Q200 versions under part numbers like BZX84-C6V8-Q, which undergo extended temperature cycling, humidity bias, and mechanical shock testing per the standard.
Can this Zener be used in series to achieve higher reference voltages?
Yes-multiple BZX84-C6V8/DG/B3,2 units may be connected anode-to-cathode in series to sum Zener voltages. Total tolerance accumulates as root-sum-square; for two devices, worst-case combined tolerance is ±7.07% at 13.6 V.
Is the SOT-23 pinout compatible with standard pick-and-place nozzles?
Yes-the SOT-23 package conforms to JEDEC TO-236AB dimensions (2.2 mm × 1.35 mm × 1.0 mm) and uses standard 0.95 mm pitch, fully supported by industry-standard SMT placement equipment and vacuum nozzles.
