STK4191V

The STK4191V is a kind of AF power amplifier.

There are some STK4191V features as follows: (1)built-in muting circuit to cut off various kinds of pop noise; (2)creatly reduced heat sink due to substrate temperature 125 guaranteed; (3)distortion 0.08% due to current mirror circuit; (4)pin-compatible with the STK4101series. The STK4101V series use the same package and are available for output 6 W to 50 W; (5)excellent cost performance.

The following is about the STK4191V maximum ratings at Ta=25: (1)maximum supply voltage, VCC max: ±53 V; (2)thermal resistance, j-c: 1.8/W; (3)junction temperature, Tjmax: 150; (4)operating substrate temperature, TC: 125; (5)storage temperature, Tstg: -30 to +125; (6)available time for load short-circuit, ts: 2s when VCC=±35.5 V, RL=8, f=50 Hz, PO=50 W.
