2SK315

The 2SK315 is a kind of N-channel junction silicon field-effect transistor. There are some features as follows: (1)ideal for FM tuners in radios, stereos, etc; (2)because it is completely packaged, sets can be made compact; (3)small crss (crss=0.08 pF typ); (4)high yfs (yfs=12.0 ms typ).

What comes next is the maximum ratings of 2SK315: (1)gate to drain voltage, VGDO: -20 V; (2)gate current, IG: 10 mA; (3)drain current, ID: 20 mA; (4)allowable power dissipation, pD: 200 mW; (5)junction temperature, Tj: 125; (6)storage temperature, Tstg: -55 to +125.

The following is the electrical characteristics of 2SK315 at Ta=25: (1)gate to drain breakdown voltage, V(BR)GDO: -20 V min at IG=-10A; (2)gate outoff current, IGSS: -10 nA at VGS=-0.5 V, VDS=0 V; (3)drain currrent, IDSS: 2.5 mA min and 24.0 mA at VDS=5 V, VGS=0 V; (4)cutoff voltage, VGS(off): -3.5 V at VDS=5 V, ID=10A; (5)input capacitance, ciss: 8.0 pF typ at VDS=5 V, VGS=0 V, f=1 MHz; (6)reverse transfer capacitance, crss: 0.08 pF typ and 0.3 pF max VDS=5 V, VGS=0 V, f=1 MHz; (7)output capacitance, coss: 6.5 dB typ at VDS=5 V, VGS=0 V, f=1 MHz.
