AI summary

EX3400B product

EX3400B is a compact 30 V N-channel SOT-23 MOSFET suited to low-voltage switching where a 10 V gate drive is available.

Best for

Low-voltage DC/DC switching
Load-switch functions
Compact power-management circuits

Avoid if

Drain voltage can exceed 30 V including transients
Thermal design cannot support SOT-23 dissipation
A fully characterized low-gate-drive MOSFET is required

Check before use

Gate drive level and RDS(on) at operating voltage
PCB thermal layout and ambient temperature
Inductive switching transient suppression

Key specifications

Drain-source voltage: 30 V
Maximum on-resistance: 26 mΩ at VGS = 10 V
Continuous drain current: 5.8 A at TA = 25°C
Package: SOT-23
