What the 1500 W peak pulse rating means for your protection design
The 1.5KE100A_R2_00001: This rating defines the device's ability to clamp a transient without exceeding its thermal limit — the 1500 W figure is the product of the clamping voltage (137 V max at Ipp) and the peak pulse current (11 A), integrated over the pulse duration. The minimum breakdown voltage is 95 V, ensuring the device does not conduct during normal operation but triggers before the protected circuitry sees damaging overvoltage. The operating temperature range spans -65°C to +175°C junction, covering military and industrial thermal environments. The DO-201AE axial-lead package supports through-hole mounting on boards where the lead bend and hole diameter follow the package drawing — the axial form factor is common in power-supply input stages and telecom line cards.
Lifecycle status and sourcing for an obsolete part
Panjit lists this part as Obsolete. The part is available in Tape & Reel (TR) or Cut Tape (CT) packaging, which affects handling in pick-and-place for through-hole axial components — the reel format suits automated insertion, while cut tape is typical for prototype or low-volume builds.
