Kt Kingtronics Bridge Rectifiers Naming Rules

Usually the bridge rectifier named in three or four digits, the first or first two number represents the rated current, the latter two figures represent the rated voltage (digital * 100V)

KBL407 : KBL = package; IR (current) = 4A; VRRM (voltage) = 700V.
KBPC2510 : KBPC = package; IR (current) = 25A; VRRM (voltage) = 1000V.
