Product details
Overview
SFF10L04GH from Taiwan Semiconductor is an AEC-Q101-qualified 10A, 200V super fast rectifier in ITO-220AB package with dual-die configuration, 0.94V typical forward voltage at 5A/25°C, 35ns reverse recovery time, and 2°C/W junction-to-lead thermal resistance-used in automotive-grade DC-DC converters and freewheeling circuits.
For engineers reviewing the SFF10L04GH datasheet, SFF10L04GH pinout, SFF10L04GH application, or SFF10L04GH equivalent, key selection criteria include VRRM=200V, IFSM=125A (8.3ms), TJ(max)=150°C, RθJL=2°C/W, and AEC-Q101 qualification for under-hood power conversion reliability.
Technical Context
This super fast rectifier employs optimized silicon epitaxial structure and low-Qrr design to achieve 35ns trr while maintaining low VF (0.94V typ @ 5A/25°C) and high surge capability (125A IFSM). Its dual-die ITO-220AB construction supports parallel conduction paths with shared thermal interface.
The device operates across -55°C to +150°C junction temperature range, features UL 94V-0 molding compound, matte tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance-enabling use in thermally demanding automotive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling clamp circuits |
| IF | 10 A - Continuous forward current rating at case temperature ≤75°C; determines heatsink sizing in 12V–48V DC-DC outputs |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); enables robustness against load dump or startup transients |
| VF @ 5A/25°C | 0.94 V (typ), 0.98 V (max) - Directly impacts conduction loss and thermal rise in high-frequency switching topologies |
| trr | 35 ns (max) - Critical for minimizing switching losses and EMI in >100kHz SMPS designs |
| RθJL | 2 °C/W - Enables efficient heat transfer to PCB copper or heatsink; supports compact thermal design in space-constrained modules |
| IR @ 200V/25°C | 10 µA (max) - Low leakage preserves efficiency in high-impedance bias networks and standby power paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | VRRM=400V, VF=0.92V@5A, trr=30ns, TO-220AC package (non-isolated tab) | Higher voltage rating but non-isolated tab requires insulating hardware; not AEC-Q101 qualified | Select when isolation is unnecessary and 400V blocking is required; verify thermal interface compatibility |
| ON Semi MUR1020CT | VRRM=200V, IF=10A, trr=35ns, VF=0.95V@5A, TO-220AB package (isolated tab), no AEC-Q101 | Same voltage/current/recovery specs but lacks automotive qualification and UL recognition | Use in industrial/commercial designs where AEC-Q101 and UL are not mandated; lower cost alternative |
Compared with STTH10R04DJF and MUR1020CT, the SFF10L04GH uniquely combines 200V VRRM, AEC-Q101 qualification, UL recognition, and ITO-220AB isolation-making it the only drop-in solution for automotive 12V/48V DC-DC converters requiring zero-insulation-gap mounting and full compliance traceability.

FAQ
What is the maximum junction temperature rating for the SFF10L04GH?
The SFF10L04GH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood environments where case temperatures may reach 125°C, provided thermal design maintains junction temperature within this limit using the specified RθJL=2°C/W path.
Is the SFF10L04GH pin-compatible with standard TO-220AB rectifiers?
Yes-the SFF10L04GH uses the ITO-220AB package, which shares identical mechanical footprint, lead pitch, and mounting hole location with TO-220AB. However, its electrically isolated tab requires no insulating washer, unlike standard TO-220AB parts, simplifying heatsink integration in the SFF10L04GH design.
Does the SFF10L04GH meet UL safety standards?
Yes-the SFF10L04GH is UL Recognized under File #E326243, confirming compliance with UL 94V-0 flammability rating for the molding compound and validated electrical insulation performance. This certification supports use in safety-critical power supplies requiring third-party safety agency approval.
What is the reverse recovery time specification for the SFF10L04GH?
The SFF10L04GH has a maximum reverse recovery time (trr) of 35ns, measured at IF=0.5A, IR=1.0A, and Irr=0.25A. This value is confirmed across the full -55°C to +150°C operating temperature range and enables efficient operation in high-frequency switching converters above 100kHz.
How does the dual-die configuration of the SFF10L04GH improve thermal performance?
The dual-die configuration in the SFF10L04GH distributes current and heat across two parallel silicon dies within one ITO-220AB package, lowering effective thermal resistance (RθJL=2°C/W) and reducing localized hot spots. This improves long-term reliability in sustained 10A operation compared to single-die 10A rectifiers with higher RθJL.
