Product details

Breakdown window and rail protection

The 1.5KE39A-G: The 27.8 A peak pulse current rating (Ipp at 10/1000 µs) means it can sink a substantial surge without failing short. The -55°C to 150°C junction temperature range covers industrial cabinets and outdoor telecom enclosures — no derating concern at the hot end of a sealed power supply.

Through-hole axial package, field-swappable

Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), this is a through-hole part that a technician can swap on site with a soldering iron and a desoldering pump — no hot-air station needed. The Tape & Box packaging suits hand-insertion runs or kitting for MRO stock. No power line protection (: No) means this is designed for DC signal or low-voltage DC rails, not AC mains — keep it on the secondary side of the supply.
