OptiMOS™ TOLG/TOLT packages for high current designs

With the goal of addressing the increased demand for high current rating, ruggedness, and extended lifetime in the market, Infineon introduces innovative packages building on its well-established TO-Leadless package. With Infineon’s TOLG and TOLT power MOSFET packages customers will achieve highest efficiency and power density in high current designs.

TOLG - TO-Leaded with Gullwing package:
Infineon's TOLG is the package encompassing the best features from both TO-Leadless and D²PAK 7-pin. It has the same footprint and excellent electrical performance as TOLL. The advantage of TOLG is the flexibility enabled by the gullwing leads featuring excellent solder joint reliability on the Aluminum-IMS board. Thanks to this feature TOLG achieves two times higher Thermal Cycling on Board (TCoB) performance compared to IPC-9701 standard requirements.

•  Features:
• •  Gullwing leads
• •  High current rating >300 A
• •  Low ringing and voltage overshoot
• •  60% space board reduction compared to D²PAK 7-pin

•  Benefits:
• •  High performance capability
• •  High system reliability
• •  High efficiency and lower EMI
• •  Optimized board utilization
• •  High TCoB

TOLT - TO-Leaded top side cooling package:
Infineon's TOLT package offers the same high current low profile benefits as the TOLL package with the additional advantage of top-side cooling for optimum thermal performance. With bottom-side cooling packages, like the TOLL or the D²PAK, the heat is dissipated via the PCB to the heatsink resulting in high power losses. With top-side cooling, the drain is exposed at the surface of the package allowing for 95% of the heat to be dissipated directly to the heatsink, achieving 20% better R_thJA and 50% improved R_thJC compared to the TOLL package.

•  Features:
• •  Low R_DS(on)
• •  High current rating >300 A
• •  Top-side cooling
• •  Negative stand-off
• •  Sn-free exposed pad

•  Benefits:
• •  Increased system efficiency enabling extended battery life time
• •  High power density
• •  Superior thermal performance
• •  Saving in cooling system
• •  Minimized thermal resistance to heatsink

•  TOLT/TOLG Target Applications:
• •  E-scooters / E-bikes
• •  Light electric vehicles
• •  Power tools
• •  Battery management systems
• •  Robots and Drones
