TM3B0039120A is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Coherent Corp. Its product description is SIC MOSFET. Review the specifications below when checking this part for your BOM.
The TM3B0039120A is an N-channel Silicon Carbide (SiC) MOSFET manufactured by Coherent Corp. It features a drain-source breakdown voltage of 1200 V and a continuous drain current of 60 A. The device is housed in a TO-247-4 through-hole package and supports operating temperatures up to +200°C. Key electrical parameters include a maximum gate-source voltage of ±20 V, a threshold voltage of 2.8 V, and a total gate charge of 172 nC. It is designed for high-efficiency power switching applications requiring robust thermal performance.
Verify the specific part number suffix against official Coherent documentation to ensure correct pinout and electrical ratings. Confirm that the TO-247-4 package variant matches your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards and RoHS directives before finalizing procurement orders.
Select this component when a 1200V rating and 60A continuous current capacity are required in a TO-247-4 package. Consider the 200°C maximum operating temperature for high-thermal environments. Ensure the driver circuit can handle the 172 nC gate charge and ±20V gate voltage limits. Compare on-resistance values if lower conduction losses are critical for the specific application design.
This SiC MOSFET belongs to Coherent's discrete power semiconductor portfolio, distinct from their optical networking products. It serves as a key component in modern power electronics, replacing traditional silicon devices to improve system efficiency and reduce cooling requirements in high-power density applications.
