IRGB5B120KDPBF

IRGB5B120KDPBF Description

The IRGB5B120KDPBF from Infineon Technologies is a high-performance NPT (Non-Punch Through) IGBT designed for robust switching applications. Rated for 1200V collector-emitter breakdown voltage and 12A continuous collector current (24A pulsed), it delivers 89W maximum power dissipation, making it suitable for medium-power circuits. Key attributes include a low Vce(on) of 3V @ 15V, 6A, ensuring efficient conduction losses, and a gate charge of 25nC for optimized drive requirements. The device features a reverse recovery time (trr) of 160ns and balanced switching energies (390µJ on, 330µJ off), striking a trade-off between speed and thermal performance. Packaged in a TO-220AB through-hole format, it is ideal for designs requiring reliable thermal management.

IRGB5B120KDPBF Features

• High Voltage & Current Handling: 1200V/12A rating with 24A pulsed capability.
• Low Conduction Losses: 3V Vce(on) at 6A reduces power dissipation.
• Optimized Switching: 22ns/100ns turn-on/off delays (td) and moderate trr for efficient operation.
• Robust Construction: NPT technology enhances thermal stability and durability.
• Standard Drive Compatibility: 15V gate voltage simplifies driver design.
• Through-Hole Mounting: TO-220AB package facilitates heat sinking for high-power applications.
