An automotive-grade TVS diode for CAN bus protection with a higher power rating in the same SOT-23 package.
Best Alternatives to PESD2CANFD24V-K
PESD2CANFD24V-K is a 24V bidirectional TVS diode in a SOT-23 package, designed for protecting CAN bus data lines. Several functional alternatives and upgrades with higher power ratings are available from various manufacturers.
AI replacement insight
Electrical risklow
Most candidates match or exceed key electrical ratings like voltage, power, and current.
Package riskmedium
While the SOT-23 package matches, pinout must be verified to ensure I/O and ground lines are connected correctly.
Sourcing risklow
Multiple alternatives are available from different manufacturers, reducing sourcing dependency.
Can it be replaced directly?
There are several strong functional alternatives for PESD2CANFD24V-K, such as ESD2CAN24T2Q and PSOT24C-LF-T7. While they share the same package and key electrical ratings, pinout verification is required for a direct drop-in replacement.
Best replacement path
ESD2CAN24T2Q is the strongest alternative as it is also designed for CAN bus, is AEC-Q101 qualified, and has a higher power rating. PSOT24C-LF-T7 is also a very good upgrade.
Main risk
The primary risk is an incorrect pinout. Although SOT-23 TVS diodes often follow a standard pin configuration (Pin 1/2: I/O, Pin 3: GND), it must be verified from the datasheet to ensure proper protection.
