BSS126 E6906

Single FETs, MOSFETs Overview

The Infineon BSS126 is a SIPMOS N-channel depletion mode small-signal transistor housed in a PG-SOT-23 package. It features a drain-source breakdown voltage of 600 V and a continuous drain current of 21 mA at 25 °C. The device supports a reverse diode dv/dt rating of 6 kV/µs and operates within a temperature range of -55 °C to 150 °C. Electrical characteristics include a gate threshold voltage banding system (J through N) for precise selection, with typical on-state resistance ranging from 280 Ω to 700 Ω depending on bias conditions.

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix to confirm the gate threshold voltage band required for your design. The datasheet indicates that reels contain transistors from a single band, identified by a letter code on the label. Ensure the selected band aligns with your circuit's threshold requirements, as individual bands cannot be ordered separately. Confirm package type and tape-and-reel specifications during procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a normally-on N-channel MOSFET with high voltage blocking capability is needed. Consider the specific gate threshold voltage band (J-N) to match control logic levels. Evaluate the thermal resistance and power dissipation limits relative to ambient temperature conditions. Verify compatibility with high dv/dt environments due to the robust reverse diode characteristics.
