Product details
Overview
BZV85-C36,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 36 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at 25 °C ambient, and 60 W non-repetitive peak reverse power. It provides stable voltage reference in low-to-medium current regulation circuits, such as power supply feedback loops and overvoltage protection in industrial control modules.
For engineers reviewing the BZV85-C36,113 datasheet, BZV85-C36,113 pinout, BZV85-C36,113 application, or BZV85-C36,113 equivalent, key selection criteria include its 34–38 V working voltage range, 50 Ω typical differential resistance at test current, −0.05 µA reverse leakage at 27 V, 25 V maximum reverse voltage before breakdown, and thermal resistance of 175 K/W junction-to-ambient with 10 mm lead length.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable reference voltage across its terminals under varying load and line conditions. Its temperature coefficient of +27.2 mV/K at 5 mA enables predictable drift compensation in precision analog circuits.
The device uses axial-leaded glass encapsulation with cathode band marking, optimized for PCB mounting with 1 cm² copper per lead to achieve 1.3 W power rating. Thermal performance is defined by junction-to-tie-point resistance of 110 K/W (4 mm lead length) and junction-to-ambient resistance of 175 K/W (10 mm lead length).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4736A | Same 36 V nominal rating but ±5 % tolerance, 1 W power rating, DO-41 package | Lacks 60 W surge rating and higher thermal resistance (225 K/W) | Preferred only for low-energy, non-surge-prone consumer applications |
| BZX85C36 | 36 V, ±5 %, 1.3 W, but plastic DO-35 package with lower moisture resistance | Not suitable for high-humidity industrial environments requiring hermetic seal | Select when cost sensitivity outweighs environmental robustness requirements |
Compared with 1N4736A and BZX85C36, BZV85-C36,113 offers superior surge resilience and hermetic reliability for mission-critical industrial regulation, while maintaining identical voltage and tolerance specs for drop-in compatibility in most PCB layouts.

FAQ
What is the maximum reverse voltage before breakdown for BZV85-C36,113?
The BZV85-C36,113 exhibits a nominal Zener voltage of 36 V with guaranteed minimum and maximum values of 34 V and 38 V respectively at 5 mA test current. Breakdown begins within this range and is not defined by a single "maximum reverse voltage" threshold-operation above 38 V risks exceeding specified differential resistance and thermal limits.
Can BZV85-C36,113 be used in surface-mount designs?
No-BZV85-C36,113 uses an axial-leaded SOD66 (DO-41) glass package designed exclusively for through-hole PCB mounting. It lacks solder pads or terminations compatible with reflow or wave soldering processes required for SMT assembly.
How does temperature affect the regulation voltage of BZV85-C36,113?
BZV85-C36,113 has a positive temperature coefficient of +27.2 mV/K at 5 mA test current, meaning its Zener voltage increases by approximately 27.2 mV per degree Celsius rise in junction temperature. This behavior is stable and repeatable, enabling predictable compensation in temperature-critical references.
Is derating required for operation above 25 °C ambient?
Yes-total power dissipation must be linearly derated above 25 °C ambient. With a junction-to-ambient thermal resistance of 175 K/W, the device reaches its 200 °C maximum junction temperature at approximately 100 °C ambient when dissipating 1.3 W. Derating curves are provided in the Nexperia datasheet Figure 1.
