CPH3337-T-TL-E-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a compact load switch circuit, where the battery voltage is only a dozen volts, but you need precise on/off control of negative current. Ordinary PMOS either lacks sufficient withstand voltage or has excessive conduction voltage drop. VBsemi CPH3337-T-TL-E-VB is designed for this—it packs -20V withstand voltage, -4A current capacity, and an on-resistance as low as 60mΩ into the compact SOT23-3 package, making low-voltage P-channel control simpler and more efficient.
