Product details
Overview
SFAF508GHC0G from Taiwan Semiconductor is a 5A, 600V super fast rectifier diode in ITO-220AC package, featuring 1.700V forward voltage at 5A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the SFAF508GHC0G datasheet, SFAF508GHC0G pinout, SFAF508GHC0G application, or SFAF508GHC0G equivalent, key selection criteria include peak reverse voltage (600V), surge current capability (125A), thermal resistance (5°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 compliance for harsh-environment deployment.
Technical Context
This device is a single-die, glass-passivated super fast recovery rectifier optimized for high-efficiency DC–DC conversion and switching-mode inverters. Its 35ns trr and low VF enable reduced switching losses and improved thermal performance in high-frequency topologies.
The ITO-220AC package provides robust thermal conduction (RθJC = 5°C/W) and mechanical stability under vibration, while matte tin-plated leads ensure reliable solderability per J-STD-002. Polarity is marked on the case, and UL recognition (E-326243) confirms safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback or boost output stages |
| IF | 5 A - Continuous average forward current; determines heatsink sizing and steady-state power handling |
| IFSM | 125 A - Peak surge current (8.3 ms half-sine); supports inrush and transient overload without failure |
| VF | 1.700 V @ 5A, 25°C - Forward voltage drop directly impacts conduction loss and efficiency at rated load |
| trr | 35 ns - Reverse recovery time; critical for minimizing switching loss and EMI in >100 kHz converters |
| RθJC | 5 °C/W - Junction-to-case thermal resistance; enables precise thermal design with known mounting interface |
| TJ max | +150 °C - Maximum junction temperature; sets upper boundary for derating curves and reliability modeling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06S | 600V VRRM, 5A IF, 35ns trr, but VF = 1.85V @ 5A; TO-220AC package, no AEC-Q101 | Not qualified for automotive; higher VF increases conduction loss by 0.15V at full load | Preferred for cost-sensitive industrial SMPS where AEC-Q101 is not required |
| ON Semi MUR560 | 600V VRRM, 5A IF, VF = 1.75V @ 5A, trr = 50ns; TO-220AC, AEC-Q101 optional (MUR560G) | Slower recovery (50ns vs. 35ns) increases switching loss in >250 kHz designs; AEC-Q101 version requires separate ordering | Acceptable for lower-frequency (<200 kHz) automotive applications where tighter trr tolerance is not critical |
Compared with STTH5L06S and MUR560G, SFAF508GHC0G delivers the lowest combined conduction–switching loss profile at 600V/5A while guaranteeing AEC-Q101 qualification in the base part number-no suffix or variant selection needed.

FAQ
What is the maximum junction temperature rating for SFAF508GHC0G?
The SFAF508GHC0G has a maximum junction temperature (TJ) of +150°C, with an operational range from –55°C to +150°C. This rating allows use in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define allowable forward current versus case temperature, and the 5°C/W junction-to-case thermal resistance enables accurate thermal modeling when mounted to a heatsink.
Is SFAF508GHC0G pin-compatible with other devices in the SFAF501G–SFAF508G family?
Yes, all SFAF501G–SFAF508G variants-including SFAF508GHC0G-share identical ITO-220AC packaging, pinout, and mechanical dimensions. The only differences are VRRM (50V to 600V) and corresponding forward voltage (VF), so PCB layout and mounting remain unchanged across the family. Polarity marking and thermal tab connection are consistent.
Does SFAF508GHC0G meet halogen-free and RoHS requirements?
Yes, SFAF508GHC0G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This ensures compatibility with environmentally regulated end equipment and supports lead-free reflow soldering processes.
What is the reverse recovery time (trr) specification for SFAF508GHC0G and how is it tested?
SFAF508GHC0G has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per JEDEC standards. This value reflects its super fast recovery performance, enabling efficient operation in high-frequency switching converters. The test circuit and waveform definitions are documented in Figure 6 of the official datasheet.
How does the "H" suffix in SFAF508GHC0G indicate AEC-Q101 qualification?
The "H" in SFAF508GHC0G explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code convention. Unlike standard SFAF508G, the "H" version undergoes additional stress testing-including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-to validate reliability for automotive applications. No separate qualification report is needed-the "H" suffix is the certified indicator.
