BZX79-B2V4,143

Single Zener Diodes Overview

The BZX79-B2V4,143 is a single Zener diode manufactured by Nexperia USA Inc. It operates in the SOD27 (DO-35) hermetically sealed glass package with axial leads for through-hole mounting. The device provides a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%. It features a maximum power dissipation of 500 mW and a low leakage current of 50 nA at reverse voltage. The component supports an operating temperature range from -65 °C to +200 °C and has a test current of 5 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction ensures long-term reliability
• Tight voltage tolerance allows for precise regulation applications
• Low differential resistance improves stability under load variations
• Extended thermal capability supports high-temperature environments

Single Zener Diodes Applications

• General purpose voltage regulation circuits
• Voltage reference sources in analog systems
• Low voltage stabilizers for sensitive components

Single Zener Diodes Procurement Notes

Verify the specific suffix '143' corresponds to the required packaging format, as it indicates Ammo Pack delivery. Confirm RoHS compliance status via the official datasheet before integration. Ensure the ±2% tolerance series matches the design requirements rather than the standard ±5% variant. Check lead time estimates directly with authorized distributors for accurate scheduling.

Single Zener Diodes Selection Notes

Select this component when a precise 2.4 V reference is required with minimal voltage drift. The ±2% tolerance distinguishes it from the C-series variants offering wider tolerances. Consider the 500 mW power rating against expected circuit dissipation. The DO-35 package suits automated through-hole assembly processes requiring robust mechanical anchoring.

Single Zener Diodes Part Context

This part belongs to the BZX79 series of low-power voltage regulator diodes. The series includes 37 types covering nominal voltages from 2.4 V to 75 V. The B-series specifically denotes the normalized E24 ±2% tolerance range, providing higher precision compared to the standard commercial grade options within the same package family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX79-B2V4 parts from different manufacturers or equivalent 2.4 V Zener diodes in DO-35 packages. Verify pinout compatibility and thermal characteristics before substitution.
