Nexperia USA Inc. BZV85-C10,133

Overview

BZV85-C10,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 10 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 serves as a precision voltage reference or shunt regulator in low-to-medium power linear power supplies and overvoltage protection circuits.

For engineers reviewing the BZV85-C10,133 datasheet, BZV85-C10,133 pinout, BZV85-C10,133 application, or BZV85-C10,133 equivalent, key selection criteria include its 10 V Zener voltage tolerance, thermal resistance (Rth(j-a) = 175 K/W), differential resistance (≤25 Ω), temperature coefficient (+4.7 to +8.5 mV/K), and suitability for stabilization in DC bias networks and analog signal conditioning.

Technical Context

This Zener diode operates in reverse breakdown mode with a specified test current of 7.0 mA and exhibits a typical differential resistance of 25 Ω at that current. Its temperature coefficient is positive and ranges from +4.7 mV/K to +8.5 mV/K, indicating predictable voltage drift with junction temperature rise.

The device is characterized under standardized thermal mounting conditions: 1 cm² copper area per lead on PCB (for Ptot = 1.3 W rating) or leads held at 55 °C at 4 mm from body (for Ptot = 1 W). Junction temperature is rated up to 200 °C, supporting operation in industrial ambient environments.

FAQ

What is the maximum continuous reverse current this diode can handle at 10 V?

The BZV85-C10,133 is not rated for continuous reverse current at its Zener voltage; instead, it is characterized at a test current of 7.0 mA. At that current, it maintains regulation within 9.4–10.6 V. Continuous operation above 7.0 mA requires derating based on thermal conditions-e.g., at 25 °C ambient with 1 cm² copper per lead, max DC power is 1.3 W, limiting average reverse current to ~130 mA at 10 V, assuming full dissipation.

Can this diode be used in series or parallel configurations for higher voltage or current handling?

Series connection of BZV85-C10,133 diodes is feasible for higher reference voltages but requires matched units to prevent current hogging due to V_Z tolerance (±5 %); parallel use is strongly discouraged because minor V_Z mismatches cause unequal current sharing and thermal runaway-no current-sharing resistors are specified in the datasheet for parallel operation.

How does the temperature coefficient affect accuracy in a 0–70 °C operating range?

With a temperature coefficient of +4.7 to +8.5 mV/K, the Zener voltage shifts +0.47 V to +0.85 V over a 100 K rise. Across 0–70 °C (ΔT = 70 K), expected drift is +0.33 V to +0.59 V-i.e., V_Z ranges from ~9.7 V to ~11.2 V. For high-accuracy systems, this drift must be compensated via calibration or circuit topology (e.g., complementary transistor biasing).

Is the SOD66 (DO-41) package compatible with standard through-hole reflow or wave soldering processes?

Yes-the SOD66 (DO-41) package is qualified for both wave and reflow soldering per Nexperia's mounting instructions. Recommended preheat: 100–150 °C for 60–90 s; peak temperature: ≤260 °C for ≤10 s; cooling rate: ≤4 °C/s. Glass body integrity is maintained under these profiles, and axial leads support standard hole sizes (0.5–0.6 mm).
