The internal photodetector includes an internal Faraday shield. This shield provides high common-mode rejection (CMR), decoupling the input side from harsh transient noise on the output side.
manufactured by Broadcom (formerly Avago/Agilent). It is designed specifically for applications requiring reliable signal isolation in harsh environments, such as industrial control and medical equipment. 1. Key Specifications & Performance High-Speed Operation:
Minimum of 15,000 V/μs at 1500 V peak, ensuring the device remains immune to high-voltage transients. Supply Voltage ( VCCcap V sub cap C cap C end-sub 1458 optocoupler datasheet
For the 4N35 at I_F = 10mA, V_CE = 10V:
In power electronics, such as solar inverters and industrial motor drives, the alternative variant HCPL-A1458 is frequently deployed as a gate driver helper. It safely conveys switching logic from low-voltage controllers to high-voltage IGBT or MOSFET stages. Vital Design and Layout Guidelines Supply Voltage ( VCCcap V sub cap C
Optimized for low-power and low-voltage systems, it features a wide VCCcap V sub cap C cap C end-sub range of 3.0V to 5.5V.
Access to the phototransistor base (on specific options) used for adjustment or tuning frequency responses. Pin 8 ( VCCcap V sub cap C cap C end-sub the 1458 is frequently used in:
The emitter and detector are physically separated by a transparent dielectric insulation barrier, ensuring no direct electrical path exists between the input and output. 2. Pin Configuration and Package Dimensions
Emitter terminal of the Channel 1 phototransistor.
: Designed for applications where signal amplification and isolation are needed simultaneously.
Because of its hermetic sealing and high-speed operation, the 1458 is frequently used in:
