2SK1470-TD-E-VB Product details
Back to previous pageProduct introduction：
2SK1470-TD-E-VB is a Single N-MOS deeply optimized for low-voltage power switching scenarios. Trench technology balances low switching loss and high reliability, while the SOT89 package achieves a good balance between heat dissipation and board area. The combination of 60V withstand voltage, 5.5A current capability, and 76mΩ on-resistance makes it an ideal cost-effective upgrade option to replace traditional DPAK or SOP-8 packages, especially suitable for high-density, high-volume applications.

VDS=60V: Suitable for 12V/24V/48V systems, leaving sufficient margin for voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 3.3V~12V logic levels, can directly connect to MCU/PMIC, eliminating level-shifting circuits.
Vth=1.7V (typical): Can enter full conduction region even with low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=76mΩ @ VGS=10V, 88mΩ @ VGS=4.5V: Low on-resistance reduces conduction losses, controllable temperature rise at full load, can reduce heat dissipation copper area.
ID=5.5A: Ample continuous current margin, can handle peak demands of most portable and automotive auxiliary loads.
Package SOT89: Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and assembly cost, better heat dissipation than conventional packages of the same size.
