Product Overview
Littelfuse LA-series radial-leaded metal-oxide varistor; the exact orderable MPN V275LA20AP is explicitly listed in the official LA datasheet.
Compared with the smaller 7 mm and 10 mm parts in the same 275 V LA family, V275LA20AP uses a 14 mm disc to provide higher surge-current and energy capability while retaining the same 275 V AC / 369 V DC continuous-voltage class.

Selection Notes
275 V AC MCOV; 14 mm disc size; 710 V clamp; 4.5 kA surge-current capability; 75 J energy rating; lead spacing/forming.
Keep continuous operating voltage below the applicable rating and check varistor/clamping levels against both the protected node and expected surge.
Manufacturer Decision-Relevant Notes
VM(AC) 275 V RMS; VM(DC) 369 V; single-pulse energy rating 75 J; maximum 8/20 µs surge current 4,500 A; varistor voltage 387–473 V at 1 mA; clamping voltage 710 V at 50 A; typical capacitance 450 pF.
Design Considerations
- Verify 275 V RMS is appropriate for the maximum continuous line voltage and temporary overvoltage profile; check the 710 V clamping level against downstream insulation and electronics; validate the expected surge waveform and repetition rate against the 4,500 A / 75 J ratings; confirm radial lead spacing, creepage and board footprint.
Application Fit
AC-line transient and surge suppression in power supplies, mains-connected equipment and industrial power interfaces where the LA-series ratings fit the surge environment.
Exact Variant and Procurement Notes
14 mm disc, branding P275L20, radial-leaded LA-series construction.
