Product details
Overview
BZV85-C20,113 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 20 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at Ttp = 55 °C, and 60 W non-repetitive peak reverse power handling - used for precision voltage stabilization in low-to-medium power linear regulator feedback paths and reference circuits.
For engineers reviewing the BZV85-C20,113 datasheet, BZV85-C20,113 pinout, BZV85-C20,113 application, or BZV85-C20,113 equivalent, this part serves as a stable, temperature-compensated voltage reference in analog sensor signal conditioning, industrial power supply monitoring, and embedded microcontroller reset circuitry where compact axial packaging and proven thermal reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 14 mA, delivering a nominal 20 V regulation at ±5 % tolerance. Its differential resistance is 24 Ω at Itest, and its temperature coefficient is +13.6 mV/K - positive and stable above 7.5 V, enabling predictable drift compensation in temperature-varying environments.
Thermal performance is defined by Rth(j-t) = 110 K/W (junction-to-tie-point, 4 mm lead length) and Rth(j-a) = 175 K/W (junction-to-ambient, 10 mm leads), supporting reliable operation up to 200 °C junction temperature when mounted on PCBs with ≥1 cm² copper per lead.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | 20 V nominal, ±5 %, 1 W power rating, DO-41 package, 22 Ω ZZT | Limited to 1 W continuous dissipation vs. 1.3 W; lower surge capability (50 W) | Preferred where board-level thermal management restricts power handling or legacy design reuse is required |
| BZX85C20 | 20 V nominal, ±5 %, 1.3 W, DO-35 package (smaller, lower thermal mass) | Higher Rth(j-a) (~200 K/W); less robust under sustained power stress | Selected when PCB space is constrained but thermal derating can be accommodated |
Compared with 1N4740A and BZX85C20, BZV85-C20,113 delivers higher continuous power handling (1.3 W), superior surge resilience (60 W), and tighter thermal resistance control (110 K/W j-to-tie-point), making it optimal for industrial applications demanding long-term stability under variable ambient conditions.

FAQ
What is the maximum continuous forward current for BZV85-C20,113?
The device is not intended for continuous forward conduction. Its absolute maximum forward current is 500 mA per IEC 60134 limiting values, but forward voltage is only specified at 50 mA (≤1 V). In normal Zener operation, forward bias is avoided; the diode functions exclusively in reverse breakdown.
How does the +13.6 mV/K temperature coefficient affect circuit accuracy?
This coefficient means the Zener voltage increases by 13.6 mV per Kelvin rise in junction temperature. At 20 V, that equates to +0.068 %/°C drift - predictable and linear above 7.5 V, allowing accurate compensation in reference designs without additional components.
Can BZV85-C20,113 replace BZX55C20 in existing designs?
Yes, with verification: both are 20 V, ±5 % Zeners in DO-41 packages, but BZV85-C20,113 offers higher power (1.3 W vs. 0.5 W), lower ZZT (24 Ω vs. ~50 Ω), and improved surge rating (60 W vs. 40 W), making it a functional upgrade where thermal headroom exists.
What PCB layout practices maximize thermal performance?
Use ≥1 cm² copper area per lead on FR-4, keep leads at least 4 mm from the glass body, and maintain ambient temperature ≤55 °C. Thermal resistance drops to 110 K/W (j-to-tie-point) under these conditions, enabling full 1.3 W dissipation without exceeding 200 °C junction limit.
