以前對 BTA/BTB 這幾種系列心中有疑問 後段電流電壓數字規格一樣,但為何區分BTA/BTB
後來在ST規格書第一頁Description注意到
The snubberless versions (BTA/BTB...W and T25 series) are specially recommended for use on inductive loads, thanks to their high commutation performances.
By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500VRMS) complying with UL standards (File ref.: E81734).
紅字這段是說: BTA系列 tab內置陶瓷絕緣2500VRMS
