HCPL-316J-500E – AVAGO

The HCPL-316J-500E is a single-channel, high common-mode transient immunity (CMTI) gate drive optocoupler in a 16-SOIC package. Manufactured by Avago Technologies (now Broadcom), it provides galvanic isolation of 5 kVrms per UL 1577 for one minute. The device integrates a GaAsP LED optically coupled to an integrated circuit with a power output stage, enabling direct driving of IGBTs and MOSFETs with collector currents up to 2.5 A peak. Internal features include undervoltage lockout (UVLO) protection with hysteresis, preventing turn-on of the power stage until sufficient gate drive voltage is available. The “-500E” suffix indicates compliance with RoHS requirements and specifies a specific tape and reel packaging option. Propagation delay is typically 250 ns, with a maximum skew of 150 ns, making it suitable for high-frequency switching applications.
