1500 W bidirectional transient suppressor
The 1.5KE82CA-E3/73: With a peak pulse power rating of 1500 W (10/1000 µs waveform), it absorbs surge energy that would otherwise damage downstream silicon — a common fit for DC bus, telecom line, or industrial power supply protection. For a 70.1 V standoff rail, this means the TVS holds the transient below 113 V before the surge current reaches 13.3 A — enough margin for a 100 V-rated MOSFET or a 120 V-rated downstream capacitor in most 48 V or 60 V DC systems.
Through-hole DO-201AA package and temperature range
The single bidirectional channel protects both polarities from a single device — no need for two unidirectional diodes in anti-series.
Supplied in Tape & Box (TB) packaging, the -/73 suffix denotes the lead-free, RoHS-compliant finish and the TB reel format. The base product number is 1.5KE82; the full ordering code must include the suffix for correct package and environmental compliance.
