The PLA172P OptoMOS® Relay is an 800 V, normally open, single-pole, 6-pin, solid-state relay (SSR). It is the first solid-state relay in the Littelfuse product portfolio that comes with guaranteed electrical parameters at 105°C ambient operating temperature. The 800-V load voltage rating with 100-mA load current capability provides additional design margin compared to the more common 600-V rated SSRs, particularly on noisy AC power line applications and high-voltage battery applications. The 105°C specifications, including the low 5 µA maximum off-state leakage current rating in conjunction with the low on-resistance, make it the ideal choice for high precision isolation current monitor applications.
