The 1.5KE43CARL4 is a TVS diode from onsemi in the Circuit Protection category. Its lifecycle status is Obsolete, meaning onsemi has discontinued production and no further manufacturing is planned. ## Is the 1.5KE43CARL4 still available to buy? The 1.5KE43CARL4 is marked Obsolete — onsemi has stopped production. ## What is the replacement for the 1.5KE43CARL4? The closely related 1.5KE43CA (also onsemi) is a common search term but is itself obsolete. For a pin-compatible alternative in the same Circuit Protection family, check the 1.5KE series from onsemi or equivalent TVS diodes from Littelfuse, Vishay, or STMicroelectronics — confirm the breakdown voltage, peak pulse power, and package before substituting.","metaTitle":"1.5KE43CARL4 onsemi Obsolete TVS Diode – Replacement &","metaDescription":"1.5KE43CARL4 from onsemi is obsolete (L1).
