Excellent alternative from Bourns for CAN bus protection with a higher power rating.
ESDCAN24-2BLY is a 24V bi-directional TVS diode in a SOT-23 package for protecting two data lines. Several functional alternatives with higher power ratings are available from multiple manufacturers.
While the SOT-23 package matches, pinout configuration for 2-line TVS diodes can vary. Verification is mandatory.
Most candidates match key voltage specs and offer higher power ratings. Minor differences in leakage or capacitance should be checked for sensitive applications.
Multiple vendors (Bourns, Littelfuse, etc.) produce similar parts, improving availability.
Yes, several functional alternatives exist for ESDCAN24-2BLY, such as CDSOT23-T24CAN and SM24CANB-02HTG. They match the package, voltage, and configuration, often with improved power ratings.
CDSOT23-T24CAN from Bourns is an excellent choice, as it is designed for the same application by a major manufacturer and offers a higher power rating. SM24CANB-02HTG is also a very strong candidate.
The primary risk is pinout incompatibility. Although SOT-23 is a standard package, the internal configuration of the diodes must match. Always verify the pinout in the candidate's datasheet.
