Is there a pin-compatible replacement for PESD1IVN27-A-ES?

Yes, several parts like PESD24VL1BA-N and GBLC24C use the same 2-pin SOD-323 package, making them pin-compatible. However, their electrical parameters differ, so they are not direct functional equivalents without review.

What risks should I check before replacing PESD1IVN27-A-ES?

Key risks include lower peak pulse power, higher clamping voltage, and different junction capacitance. These could compromise circuit protection or affect signal integrity on high-speed lines. Always verify these in your application's context.

Sourcing risklow

Many manufacturers produce similar 24V TVS diodes.

Can it be replaced directly?

No direct drop-in replacement has been identified. Several parts share the same package and voltage but have lower power ratings or different secondary characteristics requiring engineering review.

Best replacement path

Search for a 24V bidirectional TVS diode in a SOD-323 package with a peak pulse power rating of 350W or higher, and a clamping voltage at or below 42V.

Main risk

The primary risk is using a substitute with a lower power rating (e.g., 300W vs 350W) or higher clamping voltage, which may not provide adequate circuit protection.

Recommended alternatives

A parametric alternative in the same SOD-323 package. Review power rating and clamping voltage before use.
