The 1.5KE56A-E3/54: This tight window ensures the protected circuit sees a predictable clamp level before the diode conducts fully.
Housed in a DO-201AA (DO-27) axial-lead package, the diode is through-hole mounted and suited for point-of-use transient suppression on power entry boards or distribution panels. The 1.5KE series footprint is standard across the family, so a single PCB layout accommodates multiple voltage ratings.
It is a unidirectional TVS diode for general-purpose transient voltage suppression on 48 V DC rails, clamping overvoltages up to 77 V at 19.5 A peak pulse current.
