PESD15VL1BA-N is a 15V bidirectional TVS diode in a SOD-323 package. Key alternatives exist with similar or improved electrical characteristics, such as higher power ratings or lower capacitance.

AI replacement insight

Electrical risklow

Key voltage and power ratings are matched or improved in top candidates.

Package risklow

All top candidates use the same SOD-323 package.

Sourcing risklow

Multiple vendors offer suitable parts, but check regional availability.

Can it be replaced directly?

Yes, parts like TPSD3C151L and PSD15C-LF-T7 are strong candidates for replacing PESD15VL1BA-N, sharing the same package, voltage, and polarity.

Best replacement path

TPSD3C151L offers an upgrade with lower capacitance and better clamping voltage. PSD15C-LF-T7 is also a strong match but has higher capacitance.

Main risk

The main risk is ensuring the candidate's capacitance is suitable for the application's signal speed. Higher capacitance can degrade high-frequency signals.
