A strong SOT-23 alternative with matching voltage and upgraded power (500W) and current (12A) ratings.
Searching for a replacement for the PESD24VS2UT TVS diode? This guide reviews several SOT-23 alternatives, comparing key electrical parameters like voltage, power, and current to help you find a suitable substitute.
Clamping voltage, capacitance, and I-V curve differences must be checked.
All viable candidates are in SOT-23 packages, but pinout must be verified.
No drop-in replacement has been verified. PSOT24C-LF-T7 is a strong functional alternative with upgraded power handling, but pinout and dynamic characteristics must be confirmed.
PSOT24C-LF-T7 or ESD2CAN24T2Q offer higher power ratings, making them potential upgrades. However, all alternatives require datasheet review.
The primary risk is mismatch in dynamic protection characteristics like clamping voltage at specific currents and device capacitance, which can affect signal integrity.
