For detailed electrical characteristics, test circuits, and thermal design, refer directly to the original Sanyo STK412-530 datasheet. Always verify pin compatibility when substituting in legacy designs.
Engineers often ask: How does the STK412-530 compare to similar models? stk412-530 datasheet
These values are measured at Vcc = ±27V, f = 1kHz, RL = 8Ω, Ta = 25°C (from the datasheet): These values are measured at Vcc = ±27V,
