Product Summary

The STK404-140S-E is an audio power amplifier hybrid IC that consists of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO’s unique insulated metal substrate technology (IMST). The adoption of a newly-developed low thermal resistance substrate allows the STK404-140S-E to be provided in miniature packages significantly more compact than earlier Sanyo products with similar specifications.

Parametrics

STK404-140S-E absolute maximum ratings: (1)Maximum supply voltage (No signal), VCC max(0): ±78 V; (2)Maximum supply voltage, VCC max: ±73 V when RL=6Ω; (3)Thermal sensor maximum voltage, Vp: 16 V Between pins 1 and 2; (4)Thermal sensor maximum current, Ip: 30 mA Between pins 1 and 2; (5)Thermal resistance, θ j-c: 1.2 °C/W Per power transist; (6)Junction temperature, Tj max: 150℃; (7)IC substrate operating temperature, Tc max: 125℃; (8)Thermal sensor operating temperature, Tp max: 145℃; (9)Storage temperature, Tstg: –30 to +125℃; (10)Allowable load shorted time, ts: 0.3 s.

Features

STK404-140S-E features: (1)Series of pin compatible power amplifiers ranging from 45W to 180W (10%/1kHz) devices.
