Is there a pin-compatible replacement for LESD5Z5.0CT1G-HXY?

Yes, parts like TPPESD5V0S1BB are available in the same SOD-523 package, making them pin-compatible. However, you must verify that their electrical characteristics, like the slightly higher clamping voltage, are acceptable for your design.

What risks should I check before replacing LESD5Z5.0CT1G-HXY?

Before replacing, check three main risks: 1) Polarity: Ensure the replacement is also bi-directional. 2) Clamping Voltage: A higher value offers less protection. 3) Capacitance: A higher value can degrade high-speed signals.

LESD5Z5.0CT1G-HXY Alternatives, Datasheet & Cross Reference | HXY MOSFET

Find and compare replacements for the LESD5Z5.0CT1G-HXY, a 5V bi-directional TVS diode in a SOD-523 package. This guide helps you evaluate alternatives based on critical electrical and mechanical parameters.

AI replacement insight

Electrical risklow

Candidates have slightly higher clamping voltage and capacitance. This is a low risk but requires verification for sensitive applications.

Package risklow

Candidates use the same SOD-523 package, ensuring form and fit compatibility.

Can it be replaced directly?

No direct drop-in replacement has been verified. However, several functional alternatives exist in the same SOD-523 package that should be reviewed by an engineer.

Best replacement path

Review TPPESD5V0S1BB or TPESD5B5.0ST1G from TECH PUBLIC. Both match the package and key electricals but require checking the impact of slightly higher clamping voltage and capacitance.

Main risk

The primary risk is a slight reduction in protection level due to candidates having a higher clamping voltage (9V vs. target's 8V).

Recommended alternatives

A form-fit alternate with matching polarity and voltage, but requires review of its higher clamping voltage and capacitance.
