SSM3J145TU,LXHF

Single FETs, MOSFETs Overview

The SSM3J145TU,LXHF is a single-channel P-Channel enhancement-mode MOSFET manufactured by Toshiba Semiconductor and Storage. It utilizes U-MOSVI technology in a compact UFM-3 surface-mount package. Key electrical parameters include a drain-source breakdown voltage (Vdss) of -20 V, a continuous drain current (Id) of -3 A at Ta=25°C, and a maximum on-resistance (Rds(on)) of 103 mΩ at Vgs=-4.5 V. The device features a gate-source voltage range of -8 V to +6 V, a threshold voltage (Vgs(th)) of 1 V, and a total gate charge (Qg) of 4.6 nC. It supports a maximum power dissipation of 500 mW at ambient temperature and operates up to a junction temperature of +150°C. The component holds AEC-Q101 qualification for automotive reliability.

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact packaging options such as reel or cut tape quantities. Confirm that the AEC-Q101 automotive qualification status matches the project requirements. Ensure the UFM-3 footprint dimensions align with the PCB layout specifications before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component when a small-form-factor P-Channel switch is required for 20 V systems. The 103 mΩ on-resistance offers a balance between conduction loss and switching speed. Consider the 4.6 nC gate charge for drive circuit compatibility. Verify thermal management capabilities given the 500 mW power dissipation limit in the UFM-3 package.

Single FETs, MOSFETs Part Context

This part belongs to the SSM3J145TU series within Toshiba's U-MOSVI lineup. It shares the UFM-3 package form factor with other devices in the family but differs in current handling and resistance characteristics. The series targets applications requiring reliable switching in constrained spaces.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes within the same series include SSM3J140TU,LXHF and SSM3J144TU,LXHF. These alternatives share the UFM-3 package and automotive qualification but offer different current ratings and on-resistance values. Verify pinout compatibility and electrical limits before substitution.
