Nexperia USA Inc. BZV85-C6V2,113

Overview

BZV85-C6V2,113 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 6.2 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 overvoltage protection circuits.

For engineers reviewing the BZV85-C6V2,113 datasheet, BZV85-C6V2,113 pinout, BZV85-C6V2,113 application, or BZV85-C6V2,113 equivalent, key selection criteria include its 6.2 V Zener voltage, 4 Ω typical differential resistance at 3 mA test current, +0.6 mV/K temperature coefficient, 1620 µA maximum reverse leakage at 4.7 V, and suitability for PCB-mounted stabilization with 1 cm² copper per lead.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or input conditions. Its junction temperature can reach up to 200 °C, and thermal resistance from junction to tie-point is 110 K/W with 4 mm lead length.

The device exhibits a positive temperature coefficient of +0.6 mV/K at its nominal 6.2 V working point, indicating voltage increases slightly with temperature - a critical factor when used in temperature-sensitive references. Its 35 Ω max differential resistance at 3 mA ensures predictable regulation slope under dynamic load changes.

FAQ

What is the maximum continuous reverse current this Zener can handle at 6.2 V?

At nominal 6.2 V operation, the device draws approximately 3 mA test current per datasheet Table 8. With 1.3 W total power dissipation limit, the absolute maximum continuous reverse current is ~209 mA (1.3 W ÷ 6.2 V), but practical regulation current should stay below 100 mA to maintain thermal stability and avoid exceeding 200 °C junction temperature.

Can BZV85-C6V2,113 be used in place of a 6.2 V TL431-based shunt regulator?

No - the TL431 is an adjustable precision shunt regulator with 2.5 V reference and active feedback, offering 0.5 % initial accuracy and 20 ppm/°C tempco. BZV85-C6V2,113 is a passive Zener with ±5 % tolerance and +0.6 mV/K tempco, suited for less demanding applications where cost and simplicity outweigh precision requirements.

How does the 110 K/W junction-to-tie-point thermal resistance affect PCB layout?

A 110 K/W R_th(j-t) means each watt of dissipated power raises the junction temperature 110 °C above the tie-point (lead exit point). To keep T_j ≤150 °C at 1.3 W, the tie-point must stay ≤27 °C - requiring ≥1 cm² copper area per lead and minimal trace length between diode body and copper pour, per datasheet condition [1].

Is the cathode marking band polarity consistent across all BZV85 series variants?

Yes - per Section 2 "Pinning information" and Figure 6, the dark band always denotes the cathode terminal across all BZV85-Cxxx types, including BZV85-C6V2,113. This marking aligns with industry-standard DO-41 polarity convention and is verified in the official Nexperia package outline diagram.
