BZX84-B13/LF1R

Single Zener Diodes Overview

The BZX84-B13/LF1R is a voltage regulator diode manufactured by NXP USA Inc. It operates within the BZX84 series, utilizing a SOT-23 (TO-236AB) surface-mount plastic package. The device provides a nominal Zener voltage of 13 V with a tolerance of ±2%. Key electrical characteristics include a maximum power dissipation of 250 mW and a maximum reverse leakage current of 100 nA at the test current of 5 mA. The component supports a junction temperature range up to 150 °C and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in low-power applications
• Utilizes compact SOT-23 surface-mount packaging for space-constrained designs
• Offers precise voltage tolerance for reliable reference functions

Single Zener Diodes Applications

• General voltage regulation circuits
• Voltage reference sources
• Over-voltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific suffix LF1R against official NXP documentation to confirm tape-and-reel packaging details and exact manufacturing lot codes. Ensure compatibility with existing PCB footprints designated for SOT-23 packages. Confirm RoHS compliance status for the specific production batch prior to integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a 13 V reference is required in a small form factor. The ±2% tolerance offers higher precision than standard general-purpose diodes. Consider the 250 mW power dissipation limit for thermal management in dense layouts. Verify that the operating temperature range meets the environmental requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the BZX84 family of low-power Zener diodes from NXP. The series includes various breakdown voltages ranging from 2.4 V to 75 V. The BZX84-B variant specifically denotes the ±2% tolerance class, distinguishing it from the wider tolerance A and C series variants within the same package type.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Nexperia BZX84-B13 and NXP BZX84B13VL. These alternatives share identical pinouts, package dimensions, and electrical specifications, ensuring direct interchangeability in existing designs without circuit modification.
