The A1458 (also identified as the HCPL-1458 or HCPL-A1458) is a high-speed, high-gain optocoupler manufactured primarily by Avago Technologies (now Broadcom Limited). It is designed to provide high-speed signal isolation and is often used as a gate driver for power transistors like IGBTs and MOSFETs in industrial environments. Key Technical Specifications
Low Input Current: It operates efficiently with low input drive currents, typically around 13 mA, making it compatible with most standard logic families. a1458 optocoupler datasheet
Mechanical Note: The distance between the LED and phototransistor inside the A1458 is precisely controlled to ensure a CTR consistency of ±20% from batch to batch. The A1458 (also identified as the HCPL-1458 or
Derating: Above 25°C, derate total power by approximately 2.5 mW/°C. At 100°C, P_tot drops to ~150 mW. typically around 13 mA
