Combining low power, high speed (tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 40 W) and small physical size, the DG9262/9263 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG9262/9263 is built on Vishay Siliconix’s low voltage BCD-15 process. Minimum ESD protection, per Method 3015.7 is 2000 V. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG9262/9263. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
