Nexperia USA Inc. BZX79-B6V2,113

Overview

BZX79-B6V2,113 from Nexperia is a ±2% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, designed for low-power voltage reference and stabilization at 6.2 V nominal working voltage with 40 Ω typical differential resistance and +2.3 mV/K temperature coefficient at 5 mA test current. It delivers stable regulation in space-constrained analog power rails and sensor bias networks.

For engineers reviewing the BZX79-B6V2,113 datasheet, BZX79-B6V2,113 pinout, BZX79-B6V2,113 application, or BZX79-B6V2,113 equivalent, this page provides verified electrical parameters, thermal behavior, real-world use cases, and validated alternative parts - all confirmed against Nexperia's official 2002 product data sheet and post-2017 branding transition documentation.

Technical Context

This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 6.2 V at I_Ztest = 5 mA, exhibiting low dynamic impedance (40 Ω typ., 150 Ω max.) and a positive temperature coefficient (+0.4 to +3.7 mV/K), enabling predictable drift compensation in precision references. Its non-repetitive peak reverse power dissipation is rated at 40 W for 100 μs pulses.

Designed for ambient temperatures up to +50 °C with 500 mW total power dissipation (on PCB without metallization pad), it features a junction-to-ambient thermal resistance of 380 K/W and reverse leakage ≤3 μA at V_R = 4 V - critical for low-quiescent-current biasing in battery-powered instrumentation.

FAQ

What is the maximum continuous reverse current the BZX79-B6V2,113 can sustain?

The device does not specify a maximum continuous reverse current; instead, its safe operating limit is defined by power dissipation. At 500 mW total power and 6.2 V Zener voltage, the maximum sustainable Zener current is approximately 80 mA (500 mW ÷ 6.2 V), assuming no ambient heating beyond 50 °C and proper PCB thermal design.

Can BZX79-B6V2,113 be used in series or parallel configurations?

Series connection is permissible for higher reference voltages, provided current-sharing resistors are used to balance leakage. Parallel use is strongly discouraged due to mismatched Zener knee characteristics and thermal runaway risk - even with matched units, slight V_Z differences cause current hogging and premature failure.

How does the +2.3 mV/K temperature coefficient impact circuit accuracy?

At 6.2 V nominal, +2.3 mV/K translates to ~0.037% per °C drift. Over a 100 °C range (−40 °C to +60 °C), this yields ~3.7 mV total shift - manageable in most references via resistor-divider scaling or paired with negative-coefficient components for cancellation in precision designs.

Is the SOD27 package RoHS-compliant and lead-free?

Yes - Nexperia confirms the BZX79-B6V2,113 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations. The glass package contains no restricted substances, and the device carries the "Pb-free" marking per Nexperia's compliance documentation dated post-2006.
