60V-600V N-Channel Depletion Mode MOSFET

Infineon is one of the few semiconductor manufacturers worldwide to offer N-channel depletion mode MOSFETs. Compared to enhancement mode transistors, known as normally-off, depletion MOSFETs are in an on-state at zero voltage of gate-to-source (V_GS), normally-on. This makes N-channel depletion mode MOSFETs a perfect constant current source.

Areas of application include power supply startup power, over-voltage protection, in-rush-current limiter and off-line voltage reference. With one single component it is possible to realize a simple current regulator. All products are suitable for automotive applications. In order to meet special requirements, N-channel depletion mode MOSFETs are available with V_GS(th) indicator on reel.
