BZX79-B13,143

Single Zener Diodes Overview

The BZX79-B13,143 is a single Zener diode manufactured by Nexperia USA Inc., designed for through-hole mounting in the ALF2 (DO-35/DO-204AH) axial leaded package. It features a nominal Zener voltage of 13 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 400 mW and exhibits a maximum Zener impedance of 30 Ohms. Electrical characteristics include a reverse leakage current of 100 nA at 8 V and a forward voltage of 900 mV at 10 mA. It operates reliably within an extended temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the 13 V Zener breakdown voltage.
• Engineered for high thermal stability with a maximum operating junction temperature of 200°C.
• Features low reverse leakage current to minimize standby power loss in off-state conditions.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in signal paths
• Clamping applications for transient suppression

Single Zener Diodes Selection Notes

Select this component when a precise 13 V reference is required in a through-hole design. The ±2% tolerance offers higher accuracy than standard 5% variants. Ensure the circuit can handle the 400 mW power dissipation limit. The DO-35 axial package facilitates easy manual assembly or wave soldering processes compared to surface-mount alternatives.

Single Zener Diodes Part Context

This part belongs to the BZX79 series of general-purpose Zener diodes from Nexperia. The series utilizes the robust ALF2 axial leaded package, suitable for high-reliability applications. The BZX79-B13 variant specifically denotes the 13 V version within the tighter tolerance sub-series, distinguishing it from broader tolerance options like the C-series.

Single Zener Diodes Replacement Considerations

The BZX79-B13,113 is a confirmed substitute offering identical electrical specifications and package form factor. Verify that any alternative replacement maintains the same 400 mW power rating and axial lead configuration to ensure mechanical compatibility.
