Product details
Overview
BZV85-C4V3,133 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 4.3 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 serves as a precision voltage reference or shunt regulator in low-to-medium current linear power supplies and analog signal conditioning circuits.
For engineers reviewing the BZV85-C4V3,133 datasheet, BZV85-C4V3,133 pinout, BZV85-C4V3,133 application, or BZV85-C4V3,133 equivalent, this part supports stable DC biasing, overvoltage clamping, and voltage-level translation where ±5 % regulation accuracy, 13 Ω differential resistance, and −2.7 to 0 mV/K temperature coefficient are critical design constraints.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 5 mA, delivering a nominal 4.3 V stabilization voltage across a working range of 4.0 V to 4.6 V. Its differential resistance is 13 Ω at 5 mA, ensuring predictable voltage deviation under load variation.
Thermal performance is defined by junction-to-tie-point thermal resistance of 110 K/W (lead length 4 mm) and junction-to-ambient resistance of 175 K/W (lead length 10 mm), enabling reliable operation up to 200 °C junction temperature when mounted on PCBs with 1 cm² copper per lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 4.3 V (range 4.0 V to 4.6 V at 5 mA test current) |
| Tolerance | ±5 % (E24 series standard, enabling predictable binning for production) |
| Differential Resistance | 13 Ω (low impedance ensures minimal voltage shift under ±1 mA load change) |
| Temperature Coefficient | −2.7 to 0 mV/K (negative drift mitigates thermal runaway in bias networks) |
| Total Power Dissipation | 1.3 W (at Tamb = 25 °C with 10 mm leads; defines maximum continuous DC power) |
| Non-repetitive Peak Power | 60 W (for 100 µs square-wave surges; enables transient overvoltage suppression) |
| Reverse Current Limit | 1850 µA max at VR = 1 V (specifies leakage level for low-power standby circuits) |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with cathode indicated by a colored band. Leads are tinned copper-clad steel, suitable for wave or hand soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes shunt current path |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid environments |
| 1.3 W continuous power rating | Supports higher-current shunt regulation than standard 400 mW Zeners without heatsinking |

Use Value: −2.7 to 0 mV/K temperature coefficient minimizes current drift across −40 °C to +85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4731A | Same 4.3 V nominal, but ±5 % tolerance and 1 W power rating (vs. 1.3 W) | Limited surge handling (49 W vs. 60 W); unsuitable for high-energy transient clamping | Select when board space allows TO-204AA (DO-41) footprint and lower-cost sourcing is prioritized |
| BZX55-C4V3 | Same 4.3 V/±5 % spec, but 500 mW power rating and 25 Ω differential resistance | Higher impedance causes >30 mV regulation error under 2 mA load change | Prefer only for ultra-low-power biasing where 1.3 W capability is unnecessary |
Compared with 1N4731A and BZX55-C4V3, BZV85-C4V3,133 delivers superior thermal robustness (1.3 W vs. ≤1 W), lower dynamic impedance (13 Ω vs. ≥25 Ω), and higher surge resilience (60 W vs. ≤49 W), making it optimal for industrial power rails requiring sustained regulation under variable load and temperature.

FAQ
What is the maximum continuous forward current for BZV85-C4V3,133?
The absolute maximum forward current is 500 mA per IEC 60134 limiting values. However, sustained operation above 50 mA is not recommended due to thermal limitations - the 1 V forward voltage at 50 mA implies 500 mW dissipation, approaching half the 1.3 W total rating even before reverse-bias losses.
Can BZV85-C4V3,133 be used in surface-mount designs?
No - it uses an axial-leaded SOD66 (DO-41) glass package designed exclusively for through-hole mounting. The hermetic seal and lead geometry do not support reflow or hand-soldering in SMT configurations. For SMT equivalents, consider Nexperia's BZX384-C4V3 in SOD-323.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of −2.7 to 0 mV/K, the Zener voltage decreases by up to 2.7 mV per Kelvin rise. Over a 100 °C range (−40 °C to +60 °C), this introduces up to 270 mV drift - compensated in precision circuits via series thermistors or dual-Zener configurations, but acceptable for non-critical biasing.
Is derating required for operation above 25 °C ambient?
Yes - the 1.3 W rating applies only at Tamb = 25 °C. Above that, power must be linearly derated at 10.9 mW/°C based on Rth(j-a) = 175 K/W. At 75 °C ambient, maximum allowable dissipation drops to 0.73 W to maintain Tj ≤ 200 °C.
