* For the tight control of the pinch-off voltage range, we divide TC2381 into 3 model numbers to fit customer design requirement
(1)TC2381P0710 : Vp = -0.7V to -1.0V (2)TC2381P0811 : Vp = -0.8V to -1.1V (3)TC2381P0912 : Vp = -0.9V to -1.2V
If required, customer can specify the requirement in purchasing document. For special Vp requirement, please contact factory for details.
