Infineon BSS123I Series MOSFET, 100V Maximum Drain Source Voltage, 190mA Maximum Continuous Drain Current - BSS123IXTSA1


This MOSFET is a small-signal N-channel transistor designed for surface-mount applications, providing switching and amplification functions across a wide temperature range. It is intended for circuits requiring a depletion-mode device with modest current handling and moderate voltage capability, suitable for Compact assemblies where a SOT-223 package and conservative power handling are required.

Features and Benefits:


• 100 V drain-to-source rating delivers high-voltage switching capability
• 10 Ω maximum RDS(on) provides controlled on-state conduction
• 190 mA continuous drain current supports low-current loads
• 0.5 W power dissipation limits thermal stress in constrained layouts
• 0.63 nC typical gate charge enables modest switching energy demands
• ±20 V gate tolerance allows broad gate-drive flexibility

Applications


• Used for low-current high-voltage switching in control circuits
• Suitable for surface-mount power management on Compact boards
• Ideal for analogue signal attenuation or pull-down functions
• Can be used for level-shifting in mixed-voltage systems
• Used with driver stages needing depletion-mode characteristics

What ambient temperature range can it operate in?


It is specified to function correctly from -55°C up to 150°C.

What package should designers plan for when laying out the board?


The device comes in a SOT-223 surface-mount package with four pins for PCB footprint planning.

How does its gate charge affect switching performance?


A typical gate charge of 0.63 nC reduces required gate-drive energy and influences transition speed in switching topologies.

What limits the maximum continuous current in applications?


The specified continuous drain current of 190 mA defines thermal and conduction limits for sustained operation.

Is this intended as an automotive-grade component?


It is not classified to automotive standards and should not be assumed to meet automotive qualification.
