Best Alternatives to PESD2CAN

Package: SOT-23GOODWORKTransient Voltage Suppressors (TVS)Device type: Dual bidirectional TVS diodeReverse working peak voltage: 24 VReverse breakdown voltage: 26.7 to 30.5 V at IT = 1 mAPeak pulse power: 230 W at 8/20 usPeak pulse current: 4 A

PESD2CAN replacements should be selected as 24V bidirectional CAN TVS arrays in SOT-23. Pinout, surge rating, and AEC-Q101 need review.

AI replacement insight

Electrical riskmedium

best candidate is 350W vs 420W target

Package risklow

kept parts show SOT-23, 3 pins

Can it be replaced directly?

No verified pin-compatible replacement is confirmed from the provided evidence.

Best replacement path

Review CDSOT23-T24CAN-Q first, then CDSOT23-T24CAN if lower surge power is acceptable.

Main risk

Lower peak pulse power and unverified pinout.
