Product details
Overview
BZV85-C9V1,113 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 9.1 V nominal stabilization voltage with ±5 % tolerance, 1.3 W total power dissipation at 25 °C ambient, and 60 W non-repetitive peak reverse power handling. It operates as a precision voltage reference or shunt regulator in low-to-medium power linear supplies and overvoltage protection circuits.
For engineers reviewing the BZV85-C9V1,113 datasheet, BZV85-C9V1,113 pinout, BZV85-C9V1,113 application, or BZV85-C9V1,113 equivalent, key selection criteria include its 9.1 V Zener voltage, 6.5 Ω typical differential resistance at 5 mA test current, +3.8 mV/K temperature coefficient, 1340 µA maximum reverse leakage at 7.3 V, and suitability for PCB-mounted stabilization with 1 cm² copper per lead.
Technical Context
This Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across a defined current range (3–10 mA typical). Its junction temperature can reach up to 200 °C, and thermal resistance from junction to tie-point is 110 K/W with 4 mm lead length.
The device exhibits a positive temperature coefficient of +3.8 mV/K at its 5 mA test current, indicating predictable voltage drift with temperature rise. Its 25 Ω maximum dynamic impedance at 5 mA ensures tight regulation under varying load conditions in feedback or reference paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4739A | 9.1 V nominal, ±5 %, 1 W Ptot, DO-41 package, 10 Ω rdif | Lower power rating requires derating above 70 °C ambient | Select when legacy footprint compatibility is critical and power demand stays below 1 W |
| BZX85C9V1 | 9.1 V nominal, ±5 %, 1.3 W Ptot, DO-41, 7 Ω rdif, higher IR (2000 µA) | Slightly higher leakage reduces efficiency in battery-powered standby circuits | Select when sourcing consistency with older BZX85 series is required and leakage is not critical |
Compared with 1N4739A and BZX85C9V1, BZV85-C9V1,113 offers identical voltage and tolerance but superior thermal performance (110 K/W vs. ~150 K/W), tighter dynamic impedance (6.5 Ω), and lower leakage (1340 µA), making it optimal for thermally constrained or precision reference designs.

FAQ
What is the maximum continuous power dissipation for BZV85-C9V1,113?
The maximum continuous power dissipation is 1.3 W at an ambient temperature of 25 °C with 10 mm lead length and PCB mounting featuring 1 cm² copper area per lead. Derating is required above 25 °C per the specified thermal resistance of 175 K/W junction-to-ambient.
How does the temperature coefficient affect regulation accuracy?
With a +3.8 mV/K temperature coefficient at 5 mA test current, the Zener voltage increases by approximately 3.8 mV per degree Celsius rise in junction temperature. This allows predictable compensation in temperature-critical references but requires thermal management to hold regulation within ±1 % over −40 °C to +125 °C operating range.
Can BZV85-C9V1,113 be used in place of older 1N4739A diodes?
Yes - BZV85-C9V1,113 shares the same DO-41 package, 9.1 V nominal voltage, and ±5 % tolerance as 1N4739A, but offers higher 1.3 W power rating and lower 6.5 Ω dynamic impedance. Direct substitution is viable if board layout accommodates identical lead spacing and thermal requirements are verified.
What is the reverse leakage current specification at 75 % of nominal Zener voltage?
At 7.3 V (80 % of 9.1 V), the maximum reverse leakage current is 1340 µA. This value is measured at 25 °C and defines the minimum bias current needed to maintain stable Zener conduction; lower leakage improves efficiency in low-power standby circuits.
