Active production, 1500 W bidirectional TVS
The 1.5KE91CA-TP: The DO-201AE axial-lead package suits through-hole assembly for industrial power supplies, telecom rectifiers, and motor drive DC buses where high surge capability is needed. The bidirectional configuration protects lines that see both positive and negative transients, such as AC inputs or data lines referenced to a floating ground.
Clamp voltage and temperature range
At the 125 V clamp, the diode handles peak pulse current Ipp derived from the 1500 W rating — roughly 12 A for a 10/1000 µs surge. The 86.5 V minimum breakdown ensures the device does not conduct at the 77.8 V standoff, leaving margin for nominal rail variations.
Sourcing posture for the BOM line
For a BOM line requiring a 77.8 V bidirectional TVS in DO-201AE, this part is a direct fit.
