Search the manufacturer prefix (e.g., "Sharp A1458" or "Vishay A1458") – the first three letters often reveal the true brand.

The HCPL-1458 from AVAGO/AGILENT manufacturer is a IC Chips with Hermetically Sealed, Low IF, Wide VCC, High Gain Optocouplers. Veswin Electronics HCPL-1458 | Original stock,Price - Ovaga Technologies

The (commonly referred to as the HCPL-1458 ) is a high-speed, logic-gate optocoupler designed for isolation in high-performance digital and power systems . It is primarily manufactured by brands such as Broadcom/Avago (formerly Agilent) . Key Technical Specifications Never exceed the forward current ( IFcap I

Motor drive inverters, renewable energy systems (solar/wind inverters), and factory automation. Digital Isolation:

): Often rated up to 35V or 70V depending on the specific variant. Usually ranges between 50mA and 100mA. Saturation Voltage (

As environment temperatures rise, the maximum allowable collector power dissipation falls, meaning maximum system current must be derated. 6. Applications of the A1458 Optocoupler Veswin Electronics HCPL-1458 | Original stock,Price - Ovaga

The device is commonly found in an or SO-8 package. While you should always verify with the official datasheet , a standard high-speed optocoupler pinout follows this logic:

If the A1458 datasheet shows a 6-pin DIP or SMD-4 package, verify pin 6 (base connection). A base pin allows external speed adjustment but is absent in cheaper 4-pin variants.
