Product details
Overview
SFF10L05G from Taiwan Semiconductor is a 10A, 300V super fast rectifier diode in ITO-220AB package with dual-die configuration, 125A surge rating, 1.04V typical forward voltage at 5A/25°C, and 35ns reverse recovery time - deployed in switching-mode DC-DC converters requiring high-efficiency freewheeling.
For engineers reviewing the SFF10L05G datasheet, SFF10L05G pinout, SFF10L05G application, or SFF10L05G equivalent, key selection criteria include VRRM=300V, IFSM=125A, TJ(max)=150°C, RθJC=3°C/W, and AEC-Q101 qualification availability (SFF10L05GH variant).
Technical Context
This super fast rectifier uses epitaxial planar construction with optimized carrier lifetime control to achieve 35ns trr while sustaining 300V blocking capability and 10A continuous forward current. Its dual-die ITO-220AB configuration enables parallel conduction paths for thermal and current sharing.
The device operates across -55°C to +150°C junction temperature range, with RθJC=3°C/W enabling effective heat transfer to external heatsinks, and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

FAQ
What is the maximum junction temperature rating for the SFF10L05G?
The SFF10L05G has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This rating is validated under specified thermal conditions using the ITO-220AB package mounted on a heatsink per TSC's thermal performance note. Derating curves in the datasheet define safe operating current limits above 25°C ambient.
Does the SFF10L05G have AEC-Q101 qualification?
The base SFF10L05G is not AEC-Q101 qualified, but the SFF10L05GH variant - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified. This qualification covers stress testing for temperature cycling, humidity bias, and mechanical shock, making SFF10L05GH suitable for automotive power electronics applications.
What is the forward voltage specification for the SFF10L05G at elevated temperature?
At IF = 5A and TJ = 125°C, the SFF10L05G exhibits a typical forward voltage of 0.89V and a maximum of 0.96V. This reduced VF at high temperature reflects positive temperature coefficient behavior, aiding current sharing in parallel configurations and improving thermal stability during sustained load conditions.
How does the dual-die configuration of the SFF10L05G affect its electrical performance?
The dual-die configuration in the SFF10L05G provides two independent anode terminals sharing a common cathode and thermal tab. This enables symmetrical current splitting, improved thermal distribution across the die area, and redundancy - particularly valuable in high-reliability freewheeling paths where single-point failure mitigation is required.
What is the reverse recovery time (trr) test condition for the SFF10L05G?
The SFF10L05G reverse recovery time is measured under the condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, with a maximum value of 35ns. This standardized test reflects real-world switching behavior in hard-commutated circuits and is used to calculate switching losses in SMPS design calculations.
