Is there a pin-compatible replacement for BZV55-C5V1,115?

BZV55-C5V6,115 is pin-compatible as it uses the same SOD80C package. However, its Zener voltage is 5.6V, not 5.1V, which requires electrical validation for your application.

What risks should I check before replacing BZV55-C5V1,115?

Key risks include: 1) Zener voltage mismatch, which changes the regulation point. 2) Package differences, requiring a PCB layout change. 3) Lower power or temperature ratings, which could lead to component failure under stress.

BZV55-C5V1,115 Alternatives, Datasheet & Cross Reference | Nexperia USA Inc.

BZV55-C5V1,115 is a popular 5.1V, 500mW Zener diode from Nexperia in a SOD80C package. Finding a direct drop-in replacement requires matching the Zener voltage, power rating, and Mini-MELF package.

AI replacement insight

Electrical riskhigh

Zener voltage differences in same-package parts require circuit validation.

Package riskhigh

Voltage-matched parts are often in different packages, requiring a PCB redesign.

Sourcing risklow

Zener diodes are common, but finding an exact match for this combination is the challenge.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found. Alternatives require compromises on either Zener voltage or package type.

Best replacement path

For minimal board changes, evaluate BZV55-C5V6,115, but verify if the 5.6V regulation is acceptable. For a 5.1V match, a board redesign for a part like PDZ5.1B,115 is necessary.

Main risk

The primary risk is finding a part that matches both the 5.1V Zener voltage and the SOD80C package. Most alternatives fail on one of these critical parameters.

Recommended alternatives

A parametric alternative in the same SOD80C package, but with a 5.6V Zener voltage instead of 5.1V.
