Littelfuse announced the PLA172P OptoMOS® Relay, 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.
This combination of high voltage rating, high temperature range, and surface-mountable packaging is recommended for applications including:
The PLA172P OptoMOS relay includes these key benefits:
Isolation current monitor circuits for higher voltage systems >400 V require high blocking voltage, low off-state leakage current relays with high input-to-output isolation rating to prevent potential lethal current conduction to the system chassis. The PLA172P relay’s 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, making it the ideal choice for high precision isolation current monitor applications.
PLA172P OptoMOS relays are available in tape and reel format in quantities of 1,000 as well as 50 per tube. Sample requests may be placed through authorized Littelfuse distributors worldwide.
