Product details
Overview
SRAF8100 C0G from Taiwan Semiconductor is an 8 A, 100 V repetitive peak reverse voltage Schottky barrier rectifier in ITO-220AC package, featuring 0.85 V forward voltage at 8 A and 100 µA reverse current at rated VR, used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the SRAF8100 C0G datasheet, SRAF8100 C0G pinout, SRAF8100 C0G application, or SRAF8100 C0G equivalent, key selection factors include its 100 V VRRM, 150 A surge rating, 5 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (SRAF8100H), and ITO-220AC mechanical compatibility with heatsink mounting.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring over-voltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 100 V VRRM and 0.85 V VF at 8 A enable low conduction loss in mid-voltage switching topologies.
Thermal performance is defined by RθJC = 5 °C/W and maximum junction temperature of +150 °C, supporting operation under sustained load in compact power modules where thermal management is critical.
Key Specifications

| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines usable input range in 48 V–72 V DC-DC stages |
| IF | 8 A - Continuous forward current rating; supports output stages up to ~100 W at high efficiency |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients |
| VF @ 8 A, 25°C | 0.85 V - Low forward drop reduces conduction loss and heat generation vs. silicon diodes |
| IR @ 100 V, 25°C | 100 µA - Low leakage preserves efficiency in standby and light-load conditions |
| RθJC | 5 °C/W - Enables direct heatsink mounting for thermal dissipation without forced air |
| TJ max | +150 °C - Extended junction temperature rating allows operation in high-ambient industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3 | Same ITO-220AC package, 8 A / 100 V, but VF = 0.79 V typ @ 8 A; no AEC-Q101 option | Lower forward drop improves light-load efficiency; lacks automotive qualification | Select when automotive compliance is not required and sub-0.8 V VF is prioritized |
| ON Semiconductor SB8100E | ITO-220AC, 8 A / 100 V, VF = 0.87 V typ @ 8 A; AEC-Q101 qualified (SB8100EH); RθJC = 5.5 °C/W | Slightly higher thermal resistance; same automotive qualification path | Choose when cross-supplier qualification alignment is needed and 0.5 °C/W RθJC margin is acceptable |

FAQ
What is the maximum junction temperature rating for the SRAF8100 C0G?
The SRAF8100 C0G has a maximum junction temperature (TJ) rating of +150 °C, enabling reliable operation in high-ambient industrial and automotive under-hood environments. This rating is validated per the absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision K2105 and applies to both standard and AEC-Q101-qualified (SRAF8100H) versions of the SRAF8100 C0G.
Does the SRAF8100 C0G have AEC-Q101 qualification?
The base SRAF8100 C0G is not AEC-Q101 qualified; however, the SRAF8100H variant is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening and testing. Designers requiring automotive compliance must specify SRAF8100H-not SRAF8100 C0G-when sourcing for powertrain or body electronics applications.
What is the forward voltage of the SRAF8100 C0G at 8 A and 25°C?
The forward voltage (VF) of the SRAF8100 C0G is 0.85 V maximum at 8 A and 25°C, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is measured under pulse test conditions (PW = 0.3 ms) and reflects typical conduction loss in high-frequency switching applications using the SRAF8100 C0G.
Is the metal tab of the SRAF8100 C0G electrically isolated?
Yes, the metal tab of the SRAF8100 C0G is electrically isolated from the semiconductor die and terminals, consistent with the ITO-220AC package definition. This isolation allows direct mounting to a grounded heatsink without requiring an insulating pad, simplifying thermal design while maintaining electrical safety in the SRAF8100 C0G layout.
What is the reverse leakage current of the SRAF8100 C0G at rated voltage and 25°C?
The reverse leakage current (IR) of the SRAF8100 C0G is 100 µA maximum at 100 V VRRM and 25°C, per the Electrical Specifications table. This low leakage supports high efficiency in standby and light-load conditions, especially in energy-sensitive applications such as telecom rectifiers and server auxiliary supplies using the SRAF8100 C0G.
