Surge protection for a 24 V DC rail
The 1.5KE24A-G: Its 20.5 V reverse standoff voltage sits below the rail's steady-state level, so the diode does not conduct during normal operation, while the 22.8 V minimum breakdown and 33.2 V maximum clamp at 45.18 A define the window that absorbs the surge before it reaches the downstream load.
Package and board integration
Housed in a DO-201AA (DO-27) axial leaded package with a DO-201 supplier device code, the 1.5KE24A-G mounts through-hole. The axial form factor allows point-to-point wiring or insertion into a PTH board; the cathode band must be oriented toward the rail being protected, because the unidirectional design clamps only on the forward-biased polarity. The -G suffix in the 1.5KE-G series indicates a green/RoHS-compliant build. Tape & Box (TB) packaging is standard for through-hole axial parts — the parts are sequenced in a box rather than on a reel, which suits hand-insertion or vibratory-bowl feeding but not standard SMD pick-and-place.
No AEC-Q or military qualification is listed — the part is rated for General Purpose applications, so it fits commercial and industrial equipment where automotive or defense screening is not required.
