Product details
Overview
BZV85-C22,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 22 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 handling. It delivers 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-C22,133 datasheet, BZV85-C22,133 pinout, BZV85-C22,133 application, or BZV85-C22,133 equivalent, this page provides verified Zener voltage, differential resistance, temperature coefficient, thermal resistance, and surge current specifications directly tied to PCB-level mounting conditions and real-world stabilization use cases.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 22 V (20.8–23.3 V range), differential resistance of 25 Ω at test current, and a positive temperature coefficient of +16.6 mV/K - indicating voltage increases with junction temperature. Its thermal resistance from junction to tie-point is 110 K/W (lead length 4 mm), supporting reliable operation under pulsed surge conditions up to 100 µs.
The device is designed for DC voltage stabilization and transient suppression in linear power supplies and analog signal conditioning circuits. It requires no external biasing and functions as a two-terminal passive reference element, with cathode marked by a band on the glass body and anode as the unmarked lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal (20.8–23.3 V min/max); defines stable regulation point in reverse bias |
| Differential Resistance (rdif) | 25 Ω at Itest = 5 mA; determines output impedance and load regulation error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 22 V nominal, ±5 %, 1 W Ptot, DO-41 package, rdif = 23 Ω | Lower power rating limits continuous dissipation in high-ambient designs | Select when board space matches DO-41 but thermal budget restricts to ≤1 W average load |
| BZX85C22 | 22 V nominal, ±5 %, 1.3 W Ptot, DO-41, rdif = 30 Ω, TC = +17 mV/K | Slightly higher differential resistance and temperature coefficient reduce regulation precision | Choose for legacy compatibility where minor VZ drift and ripple rejection trade-offs are acceptable |
Compared with 1N4744A and BZX85C22, BZV85-C22,133 offers identical power rating to BZX85C22 but lower rdif and tighter TC match to mid-range Zeners, making it preferable for precision analog feedback and transient-clamping dual-role implementations.

FAQ
What is the maximum continuous reverse current the BZV85-C22,133 can handle at 25 °C?
The device supports a maximum continuous Zener test current of 5 mA per datasheet Table 8, corresponding to 110 mW steady-state dissipation. At full 1.3 W rating, average reverse current must be limited to ~59 mA - but only with adequate PCB copper heatsinking (1 cm² per lead) and ambient temperature control.
How does the +16.6 mV/K temperature coefficient affect circuit performance?
This positive coefficient means the Zener voltage rises by 16.6 mV per °C increase in junction temperature. In a 22 V reference, that equates to ~0.075 %/°C drift - acceptable for non-precision applications but requires compensation in high-accuracy systems via series thermistors or complementary TC elements.
Can BZV85-C22,133 replace BZX55C22 in existing designs?
Yes, with validation: both are DO-41 packaged 22 V Zeners with ±5 % tolerance and similar rdif. However, BZV85-C22,133 has higher PZSM (60 W vs. 40 W) and lower Rth(j-a) (175 K/W vs. ~200 K/W), improving surge robustness and thermal response - verify layout copper area meets Nexperia's 1 cm²/lead requirement.
Is the SOD66 package compatible with automated through-hole assembly?
Yes - the SOD66 (DO-41) package features axial leads with 2.6 mm body diameter and standardized 25.4 mm length, fully compatible with industry-standard wave soldering, selective soldering, and manual insertion tooling. Lead spacing and bend radius align with IPC-7351B through-hole footprint guidelines.
