Product Overview

The HCPL-J312-000E is a high-performance high-speed optocoupler designed for industrial control and power electronics applications. It features high isolation voltage (3750Vrms) and fast signal transmission (500ns switching speed) to precisely drive IGBTs and MOSFETs, widely used in motor control, industrial inverters, and switching power supplies.

Key Features

• High Isolation & Anti-Interference:
  Provides 3750Vrms isolation voltage and 15kV/μs common-mode rejection (CMR) (VCM=1500V), effectively separating high-voltage circuits from low-voltage control signals for system stability.
• Wide Operating Range:
  15-30V wide input voltage and -40°C to 100°C industrial temperature range ensure reliable operation in harsh environments.
• Low Power & High Drive Capability:
  2.5A peak output current and 0.5V low-level output voltage directly drive 1200V/100A IGBTs without additional power stages.
• Intelligent Protection:
  Built-in undervoltage lockout (UVLO) automatically shuts down the output when the supply voltage drops below the threshold, preventing device damage.
• Fast Response & Precision Control:
  500ns switching speed and ±0.35μs channel delay difference meet real-time requirements for high-frequency switching applications.

Technical Specifications

Typical Applications

• Industrial Automation:
  Used in PLCs and sensor interfaces, the high isolation protects control systems from high-voltage interference, ensuring stable signal transmission.
• EV Drive Systems:
  Precisely drives IGBT modules in vehicle inverters, supporting wide temperature range and fast switching for improved motor efficiency and reliability.
• Medical Device Power Supplies:
  Provides electrical isolation to prevent current leakage while meeting low-power and high-precision control needs.
• Communication Base Station Power:
  Implements feedback control in switching power supplies, optimizing efficiency and noise immunity via low-level output voltage and high CMR.
• Smart Grid Systems:
  Applied in power monitoring equipment, adapting to complex grid environments through high-speed signal transmission and wide operating voltage.
