BSP129 Description

Short technical summary and product information.

The Infineon BSP129 is a SIPMOS® Small-Signal-Transistor featuring N-channel depletion mode operation. It is designed for various electronic applications requiring reliable switching and amplification.

 

Key electrical characteristics include a drain-source breakdown voltage of 240V and a gate threshold voltage ranging from -2.1V to -1V. The drain-source on-state resistance is specified at a maximum of 20W at VGS=0V, ID=25mA, and a typical 4.2W at VGS=10V, ID=0.35A. Dynamic characteristics such as input capacitance (Ciss) are typically 82pF, and output capacitance (Coss) is typically 12pF.

 

This MOSFET is qualified according to AEC Q101 and features Pb-free lead plating, making it RoHS compliant. It is supplied in a PG-SOT223 package, suitable for surface mounting. The device operates within a temperature range of -55°C to 150°C.

 

The BSP129 is also dv/dt rated and available with a VGS(th) indicator on reel, aiding in production and quality control. Its robust design and specifications make it a suitable component for demanding applications.
