Product details
Overview
SFF508GHC0G from Taiwan Semiconductor is a 600 V, 5 A super fast rectifier diode in ITO-220AB package with dual-die configuration, 1.70 V forward voltage at 2.5 A/25°C, 35 ns reverse recovery time, and AEC-Q101 qualification - used in high-efficiency DC-DC converters and automotive switching inverters.
For engineers reviewing the SFF508GHC0G datasheet, SFF508GHC0G pinout, SFF508GHC0G application, or SFF508GHC0G equivalent, key selection factors include its 600 V repetitive peak reverse voltage, 70 A surge capability, 5.5 °C/W junction-to-case thermal resistance, AEC-Q101 qualification status, and ITO-220AB mechanical mounting requirements.
Technical Context
This device is a single-package dual-die super fast recovery rectifier optimized for high-frequency switching applications. It delivers low conduction loss (VF = 1.70 V @ 2.5 A, 25°C) and fast switching (trr = 35 ns), enabling efficient operation in SMPS topologies where reduced reverse recovery charge minimizes switching losses.
The ITO-220AB package provides robust thermal performance (RθJC = 5.5 °C/W) and mechanical reliability per JESD201 Class 2 whisker testing. Its AEC-Q101 qualification confirms suitability for automotive under-hood power conversion systems requiring extended temperature operation (–55°C to +150°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input stages of 400 VAC rectification or 300 VDC bus systems with safety margin |
| IF | 5 A continuous - rated for sustained conduction in medium-power DC-DC outputs |
| IFSM | 70 A (8.3 ms half-sine) - withstands startup surges and transient overloads without failure |
| trr | 35 ns - enables operation up to ~3 MHz switching frequency with minimal tail current loss |
| VF | 1.70 V @ 2.5 A, 25°C - reduces conduction loss vs. standard fast rectifiers (e.g., 1N5408 VF ≈ 1.2 V but trr > 2 µs) |
| CJ | 50 pF @ 1 MHz, 4 V - limits capacitive coupling noise in high-dv/dt gate-drive or snubber circuits |
| RθJC | 5.5 °C/W - allows 9.1 W power dissipation at 50°C case temperature before reaching TJ max |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06H | 600 V, 5 A, trr = 30 ns, VF = 1.75 V @ 2.5 A, TO-220AC package (non-isolated tab) | Non-isolated tab requires insulating hardware; lacks AEC-Q101 qualification | Preferred where thermal interface simplicity outweighs automotive qualification needs |
| ON Semi MUR560HE3/A | 600 V, 5 A, trr = 35 ns, VF = 1.75 V @ 2.5 A, TO-220AC package, AEC-Q101 qualified | Same trr and qualification, but non-isolated tab and higher VF increases conduction loss by 3% | Valid alternative if isolation is handled externally and 0.05 V VF penalty is acceptable |
Compared with STTH5L06H and MUR560HE3/A, SFF508GHC0G uniquely combines AEC-Q101 qualification, electrically isolated ITO-220AB tab, and 1.70 V VF - making it optimal for space-constrained automotive modules requiring no external insulation or thermal derating.

FAQ
What is the maximum junction temperature rating for SFF508GHC0G?
The SFF508GHC0G has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating range from –55°C to +150°C. This rating is supported by thermal characterization data showing RθJC = 5.5 °C/W and confirmed in the Absolute Maximum Ratings table of the official TSC datasheet Version I2105. Operation above this limit risks permanent degradation of the silicon die.
Is SFF508GHC0G pin-compatible with standard TO-220 rectifiers?
No, SFF508GHC0G uses the ITO-220AB package, which features an electrically isolated metal tab - unlike standard TO-220AC/AB packages. While outline dimensions match TO-220, the isolation requires different mounting hardware and PCB layout. The pinout remains Anode1–Cathode–Anode2–Cathode with common cathodes, but thermal pad isolation must be accounted for in layout.
Does SFF508GHC0G meet automotive qualification standards?
Yes, SFF508GHC0G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the Features section of the TSC datasheet. This qualification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock - validating its use in automotive powertrain and body electronics applications.
What is the reverse recovery time (trr) specification for SFF508GHC0G?
The reverse recovery time (trr) for SFF508GHC0G is specified as 35 ns maximum under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured per JEDEC standard and applies across the full temperature range; typical trr at 25°C is consistent with the 35 ns max, enabling reliable operation in 200–500 kHz switching converters.
How does the dual-die configuration of SFF508GHC0G affect circuit implementation?
The dual-die configuration in SFF508GHC0G provides two independent anodes sharing a common cathode, allowing flexible topologies such as dual-output flyback, interleaved boost, or redundant freewheeling paths. Unlike single-die devices, it eliminates the need for external paralleling while maintaining matched thermal and electrical characteristics between dies - critical for balanced current sharing.
