Product details
Overview
BZX79-C6V2,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode in DO-35 (SOD27) glass package, designed for low-power voltage reference and stabilization at nominal 6.2 V with 40 Ω typical differential resistance and 0.4 to 3.7 mV/K temperature coefficient. It delivers stable regulation in power supply feedback paths, sensor biasing, and overvoltage protection circuits with ≤3 μA reverse leakage at 4 V.
For engineers reviewing the BZX79-C6V2,113 datasheet, BZX79-C6V2,113 pinout, BZX79-C6V2,113 application, or BZX79-C6V2,113 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (380 K/W), non-repetitive surge capability (40 W/100 μs), and junction temperature range (−65 to +200 °C).
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 5 mA, delivering precise DC voltage reference under stable thermal conditions. Its differential resistance of 40 Ω (typ.) ensures minimal output voltage variation across load changes, while its temperature coefficient of +0.4 to +3.7 mV/K enables predictable drift behavior in ambient-varying environments.
The device uses hermetically sealed axial-leaded glass construction (SOD27/DO-35), optimized for PCB mounting without metallization pad and rated for 500 mW total power dissipation at Tamb = 50 °C. Non-repetitive peak reverse power handling reaches 40 W for 100 μs pulses, supporting transient suppression in low-energy clamp applications.

FAQ
What is the maximum continuous power dissipation for BZX79-C6V2,113?
The device is rated for 500 mW total power dissipation at ambient temperature of 50 °C with leads mounted on a PCB without metallization pad and maximum lead length of 8 mm. Derating is required above 50 °C at 4.2 mW/°C based on Rth j-a = 380 K/W.
Does BZX79-C6V2,113 have a specified forward voltage?
Yes - forward voltage is 0.9 V maximum at 10 mA forward current and Tj = 25 °C. This value is relevant for polarity verification and low-current forward conduction checks during functional testing.
Can BZX79-C6V2,113 be used in place of a 6.2 V TL431-based reference?
No - the BZX79-C6V2,113 is a passive two-terminal Zener diode with no active regulation or adjustable output. It lacks the precision, low dynamic impedance, and programmability of the TL431, making it unsuitable for high-accuracy feedback or adjustable shunt regulator applications.
What is the cathode marking convention for this DO-35 package?
The cathode is identified by a single color band located near one end of the glass body. When oriented with the band to the left, the right-hand lead is the anode and the left-hand lead is the cathode - consistent with JEDEC DO-35 standard marking practice.
