MD621 - Optically Coupled MOSFET Driver

General Description

The MD621 consists of an input drive LED optically coupled to a photodiode array output designed to drive highly capacitive loads, including the gate of a power MOSFET.

The active discharge circuit of the PDA assures quick discharge of MOSFETs, providing fast turn-off times.

Key Features

  • Compact 6 pin DIP/SMD package.
  • Built in active discharge circuit for fast turn-off.
  • Fast Turn-On.
  • 12V Gate Drive Voltage.
  • High Input-to-Output Isolation (up to 5kVRMS).
  • Long Life / High Reliability.
  • RoHS / Pb-Free / REACH Compliant Agency Approvals UL/C-UL: VDE: File # E201932 File # 40035191 (EN 60747-5-2) Absolute Maximum Ratings The values indicated are absolute stress ratings. Functional operation of the device is not implied at these or any conditions.
