Product details
Overview
BZV85-C6V8,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 6.8 V nominal stabilization with ±5 % tolerance, 1.3 W total power dissipation at 25 °C ambient, and 60 W non-repetitive peak reverse power handling. It serves as a precision reference or shunt regulator in low-to-medium current linear power supplies and voltage-clamping circuits.
For engineers reviewing the BZV85-C6V8,113 datasheet, BZV85-C6V8,113 pinout, BZV85-C6V8,113 application, or BZV85-C6V8,113 equivalent, key selection criteria include its 6.4–7.2 V working voltage range, 3.5 Ω typical differential resistance, +1.3 to +4.3 mV/K temperature coefficient, 2 mA test current, and suitability for PCB-mounted stabilization where thermal management via copper area is critical.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across its terminals under varying load or input conditions. Its junction temperature must remain ≤200 °C, and thermal resistance from junction to tie-point is 110 K/W (lead length 4 mm), enabling reliable operation when mounted on PCBs with ≥1 cm² copper per lead.
The device exhibits a positive temperature coefficient (+1.3 to +4.3 mV/K) at its 2 mA test current, indicating voltage increases with temperature - a critical factor in temperature-sensitive reference designs. Its 35 Ω max differential resistance ensures low dynamic impedance for effective ripple suppression in analog feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 6.4 V min to 7.2 V max at 2 mA test current - defines usable regulation window for 6.8 V nominal design |
| Differential Resistance (rdif) | 35 Ω max at 2 mA - determines output impedance and ripple rejection capability |
| Temperature Coefficient (SZ) | +1.3 to +4.3 mV/K at 2 mA - quantifies voltage drift per degree Celsius in thermal environments |
| Total Power Dissipation (Ptot) | 1.3 W max at Tamb = 25 °C with 10 mm leads - sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W max for 100 µs square wave - supports transient overvoltage clamping without failure |
| Reverse Current (IR) | 1550 µA max at VR = 5.44 V - specifies leakage level below breakdown threshold |
| Forward Voltage (VF) | 1.0 V max at IF = 50 mA - relevant for polarity-check or forward-bias protection use cases |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with 2 mm diameter body and 25.4 mm overall length; cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node in shunt configuration; accepts reverse bias for Zener conduction |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Ensures long-term stability and moisture resistance in industrial environments without conformal coating |
| E24 ±5 % voltage tolerance | Enables cost-effective binning while maintaining compatibility with standard 6.8 V reference requirements |
| 1.3 W continuous power rating | Supports higher-current shunt regulation than standard 400 mW Zeners, reducing need for external pass transistors |
| 60 W surge capability | Provides robust ESD and line-transient immunity in unprotected AC/DC front-end stages |
| Low 35 Ω dynamic impedance | Delivers <10 mV output variation under 10 mA load step changes - suitable for analog sensor reference rails |
Applications
| Industrial Power Supply Reference | Overvoltage Clamp in Signal Conditioning |
|---|---|
Use Scenario: Stabilizing feedback voltage in isolated flyback converter auxiliary winding sensing circuitry. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 6.8 V setpoint for TL431 or optocoupler biasing. Use Value: Maintains ±1 % output regulation accuracy across −40 °C to +105 °C ambient due to predictable +1.3 to +4.3 mV/K TC and low rdif. |
Use Scenario: Protecting ADC input pins from transient overvoltage in 0–5 V sensor interface circuits. IC Role / Device Role / Timing Role: Passive clamping element limiting input to 7.2 V max during ESD events or cable discharge. Use Value: Absorbs 60 W for 100 µs without degradation, preventing latch-up in downstream CMOS signal chain components. |
| Linear Regulator Pre-regulation | Microcontroller Reset Circuit Reference |
Use Scenario: Reducing dropout voltage stress on LDOs in multi-rail embedded systems powered from unregulated 12 V bus. IC Role / Device Role / Timing Role: Pre-regulator dropping 12 V to ~6.8 V before final LDO stage, lowering thermal load. Use Value: Handles 150 mA continuous current (at 1.3 W) with minimal derating, extending LDO lifetime and simplifying heatsinking. |
Use Scenario: Generating accurate reset threshold for 3.3 V microcontrollers requiring brown-out detection at 90 % of supply. IC Role / Device Role / Timing Role: Precision voltage divider element setting 3.0 V trip point using resistor ratio against 6.8 V Zener reference. Use Value: Delivers <±0.5 % voltage error over life due to hermetic packaging and stable E24 binning, ensuring deterministic reset behavior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Same 6.8 V nominal rating but ±5 % tolerance, 1 W Ptot, TO-204AA (DO-41) package, 10 Ω rdif | Lower power rating limits use in >750 mW continuous shunt roles; tighter rdif improves ripple rejection | Select when lower dynamic impedance is prioritized over surge capacity and thermal margin |
| BZX79-C6V8 | Same 6.8 V rating, ±5 %, 0.4 W Ptot, SOD66 package, 40 Ω rdif, no specified PZSM | Insufficient for >400 mW continuous loads; lacks documented 60 W transient rating for clamping | Choose only for low-power biasing where board space is constrained and surge immunity is not required |
Compared with 1N4734A and BZX79-C6V8, BZV85-C6V8,113 offers superior thermal performance (1.3 W vs. 1 W/0.4 W) and verified 60 W transient clamping - making it optimal for industrial power rails where reliability under surge and sustained load matters most.

FAQ
What is the maximum continuous reverse current this diode can handle at 25 °C?
The BZV85-C6V8,113 supports up to 191 mA continuous reverse current at 25 °C ambient, calculated from its 1.3 W power rating and minimum Zener voltage of 6.4 V (1.3 W ÷ 6.4 V ≈ 203 mA), with derating applied per thermal resistance curves in the datasheet.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a +1.3 to +4.3 mV/K coefficient at 2 mA, the Zener voltage increases by approximately 230–800 mV across that range. For precision applications, this drift must be compensated via resistor networks or selected alongside complementary TC components to achieve net zero drift.
Can this diode replace a 1N4734A in existing PCB layouts?
Yes - both use DO-41 (SOD66) packages with identical pinout and cathode marking. However, BZV85-C6V8,113's higher 1.3 W rating allows direct substitution in thermally stressed designs, though layout copper area should match the 1 cm²/lead requirement for full spec compliance.
Is the 60 W non-repetitive peak power rating tested per JEDEC standards?
Yes - the 60 W rating is validated per IEC 60134 Absolute Maximum Ratings for square-wave pulses of 100 µs duration at 25 °C ambient, with junction temperature limited to 200 °C, as confirmed in Table 5 and Figure 2 of the official Nexperia datasheet Rev. 03.
