** For the tight control of the pinch-off voltage range, we divide TC2591 into 3 model numbers to fit customer design requirement
(1)TC2591P1519 : Vp = -1.5V to -1.9V (2)TC2591P1620 : Vp = -1.6V to -2.0V (3)TC2591P1721 : Vp = -1.7V to -2.1V
If required, customer can specify the requirement in purchasing document. For special Vp requirement, please contact factory for details.
