HCPL-3120-000E Gate Drive Optocoupler
2.5A Peak Output Current meets High CMR Noise Immunity – The Professional IGBT & MOSFET Driver Choice for Industrial Inverters.
The High-Isolation Gate Driving Advantage
The HCPL-3120-000E represents a premier flagship modular solution for space-constrained, high-power switching systems demanding absolute signal isolation and rugged gate drive capability. Engineered by Broadcom (Avago Technologies), this 2.5 Amp peak output current optocoupler drives motor control IGBTs and MOSFETs flawlessly without localized switching distortion. Housed in a standardized 8-pin dual-in-line package layout, it secures pure, deterministic signal transmission pathways and eliminates systemic feedback loops.
- 2.5A Maximum peak output current driving power transistors directly
- 15 kV/µs Minimum common-mode rejection (CMR) suppressing harsh transient noise
- Under-Voltage Lockout (UVLO) protection mechanism with hysteresis safeguards
