2SK1959-T1-AZ-VB Product details
Back to previous pageProduct introduction：
**Product Introduction** Are you designing a compact fast charger or battery management module, with limited PCB space but needing to handle 6.8A current output with low heat generation? Ordinary MOS transistors are either too large in package or have high conduction losses. VBsemi 2SK1959-T1-AZ-VB is designed for this—it integrates 30V withstand voltage, 6.8A current capability, and an on-resistance as low as 22mΩ into a SOT89 package, making high-density low-voltage power design more effortless.
