Product details
Overview
BZX79-C6V8,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 6.66–7.2 V nominal Zener voltage at 5 mA test current, 30–80 Ω differential resistance, and 500 mW total power dissipation at Tamb = 50 °C. It serves as a low-power voltage reference or stabilization element in linear power supplies, sensor biasing circuits, and overvoltage protection clamps.
For engineers reviewing the BZX79-C6V8,113 datasheet, BZX79-C6V8,113 pinout, BZX79-C6V8,113 application, or BZX79-C6V8,113 equivalent, this part is selected for precision low-current voltage referencing where ±5% tolerance, low dynamic impedance (<80 Ω), and stable temperature coefficient (+1.2 to +4.5 mV/K) are required in compact through-hole designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 6.66–7.2 V at IZ = 5 mA, exhibiting a typical differential resistance of 30 Ω and a positive temperature coefficient of +3.0 mV/K at that current. Its non-repetitive peak reverse power dissipation is rated at 40 W for 100 μs pulses.
The device uses axial-leaded SOD27 packaging with cathode indicated by a band, optimized for PCB mounting without metallization pads. Thermal resistance from junction to ambient is 380 K/W under standard conditions, limiting continuous operation to ≤500 mW at Tamb = 50 °C per derating curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.66–7.2 V at IZ = 5 mA - defines stable regulation range for low-power reference use |
| Differential Resistance (rdif) | 30–80 Ω - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +1.2 to +4.5 mV/K - quantifies VZ drift with junction temperature change |
| Total Power Dissipation (Ptot) | 500 mW at Tamb = 50 °C - sets maximum continuous DC power handling on standard PCB |
| Reverse Current (IR) | 2 μA max at VR = 4 V - ensures low leakage in standby or high-impedance bias networks |
| Package | SOD27 (DO-35) - hermetically sealed axial glass package with cathode band marking |
| Non-repetitive Peak Power | 40 W for 100 μs - supports transient surge suppression in clamp applications |
Pinout & Package
SOD27 (DO-35) is a hermetically sealed axial-leaded glass package with two terminals: anode and cathode. The cathode is marked by a colored band on the glass body. Leads are tinned copper alloy, suitable for wave or hand soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / reverse breakdown reference node | Connected to lower-potential side in Zener configuration; defines polarity for proper biasing |
| Cathode | Zener breakdown terminal / regulated output node | Marked with band; connected to higher-potential side; delivers stable VZ when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not critical, e.g., supply rail monitoring |
| Low differential resistance (30 Ω typ.) | Minimizes output voltage variation under changing load current in feedback or bias networks |
| Hermetic SOD27 glass package | Ensures long-term stability and moisture resistance in industrial environments without conformal coating |
| Positive temperature coefficient (+3.0 mV/K) | Allows predictable VZ drift compensation when paired with negative-TC components |
| 40 W non-repetitive peak power rating | Supports transient overvoltage clamping in low-energy surge scenarios (e.g., ESD protection front-end) |
Applications

IC Role / Device Role / Timing Role: Threshold detector establishing reliable brown-out detection point. Use Value: Provides sharp, repeatable 6.8 V turn-on with <2 μA leakage to avoid loading weak reset pull-up networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-B6V8,113 | ±2% tolerance (6.66–6.94 V), lower rdif (30–40 Ω), tighter TC (±1.2 mV/K) | Higher precision reference needed; lower noise/ripple in sensitive analog stages | Select when regulation accuracy >±3% is required and cost premium is acceptable |
| 1N4734A | 6.8 V nominal, ±5%, 1.5 W Ptot, DO-41 package, rdif ≈ 3.5 Ω | Higher power handling and lower impedance for higher-current references | Select when >500 mW continuous dissipation or <5 Ω dynamic impedance is required |
Compared with BZX79-B6V8,113, this part trades precision for cost and availability; compared with 1N4734A, it offers smaller footprint and lower thermal mass but reduced power capability-ideal for space-constrained, low-power analog monitoring.

FAQ
What is the maximum continuous power dissipation for BZX79-C6V8,113?
The maximum continuous power dissipation is 500 mW at ambient temperature ≤50 °C with leads ≤8 mm long and no PCB metallization pad. At higher temperatures, derating applies per the 380 K/W junction-to-ambient thermal resistance; for example, at 70 °C ambient, max. dissipation drops to ~370 mW.
How does the temperature coefficient affect regulation accuracy?
The BZX79-C6V8,113 has a typical temperature coefficient of +3.0 mV/K, meaning its Zener voltage increases by ~3 mV per °C rise in junction temperature. Over a 100 °C range (−40 to +60 °C ambient, assuming self-heating), VZ shifts by up to ~300 mV-requiring system-level compensation if sub-1% stability is needed.
Can BZX79-C6V8,113 be used in surface-mount designs?
No-it is exclusively packaged in axial-leaded SOD27 (DO-35) glass, designed for through-hole mounting. For SMT equivalents, consider Nexperia's PZM series (e.g., PZM6.8NB,115) in SOD-123, which offer comparable 6.8 V regulation but in surface-mount format with different thermal and electrical characteristics.
What is the reverse leakage current at 4 V?
At VR = 4 V and Tj = 25 °C, the maximum reverse leakage current is 2 μA. This value remains stable across the full operating temperature range (−65 to +200 °C), making it suitable for high-impedance bias networks where leakage-induced error must stay below 100 nA in precision applications.
