Features
1. Small SOP4-pin package The device es in a super-miniature SO package 4-pin type measuring (W) 4.3×(L) 4.4×(H) 2.1 mm (W) .169×(L) .173×(H) .083 inch 2. Low on-resistance The AQ❍4 series (normally closed type) has a low on-resistance. This has been achieved thanks to the built-in MOSFET processed by our proprietary method, DSD (Doublediffused and Selective Doping) method.
