Product Overview
V175LA20AP is a 20 mm Littelfuse LA-series MOV intended for AC-line and general-purpose transient suppression. The 175 V grade is specified for 175 VAC RMS or 225 VDC continuous operation and provides substantially more surge-current capability than smaller-disc members of the same voltage family.
The part is useful where a radial leaded surge suppressor is required and the circuit can accommodate the 20 mm disc footprint.
Technical Specifications
| Parameter | Confirmed Information |
|---|---|
| VAC continuous | 175 V RMS |
| VDC continuous | 225 V |
| Energy rating | 90 J |
| Peak surge current | 6,500 A, 8/20 µs |
| Varistor voltage at 1 mA | 243 V to 297 V |
| Maximum clamping voltage | 455 V at 100 A |
| Typical capacitance | 1400 pF |
| Disc diameter | 20 mm |
Selection Considerations
The V175 designation refers to continuous AC rating, not nominal clamp voltage. For replacement sourcing, keep the complete V175LA20AP code because LA-series devices with the same voltage grade are available in smaller discs and lower surge ratings.
