Taiwan Semiconductor Corporation SRAF10100 C0G

Overview

SRAF10100 C0G from Taiwan Semiconductor is a 10A, 100V repetitive peak reverse voltage Schottky barrier rectifier in ITO-220AC package, featuring 0.85V forward voltage at 10A/25°C, 200A surge capability, and AEC-Q101 qualification option (SRAF10100H). It serves as primary output rectifier in high-efficiency DC-DC converters.

For engineers reviewing the SRAF10100 C0G datasheet, SRAF10100 C0G pinout, SRAF10100 C0G application, or SRAF10100 C0G equivalent, key selection criteria include VRRM=100V, VF=0.85V @10A, IR=100µA @25°C, RθJC=4°C/W, and ITO-220AC thermal/mechanical interface compatibility.

Technical Context

This Schottky rectifier uses a single-die construction with guard ring for over-voltage protection and meets UL 94V-0 flammability rating. Its junction-to-case thermal resistance of 4°C/W enables high-power dissipation in constrained thermal environments.

Designed for switching-mode operation, it delivers low conduction loss (VF ≤ 0.85V) and high dv/dt immunity (10,000 V/µs), supporting fast-switching topologies in automotive and industrial power supplies where efficiency and reliability are critical.

FAQ

What is the maximum junction temperature rating for SRAF10100 C0G?

The SRAF10100 C0G has a maximum junction temperature (TJ max) of 150°C, enabling operation in high-ambient environments like automotive engine compartments or sealed industrial enclosures. This rating is validated under specified thermal conditions and must be maintained using appropriate heatsinking per the 4°C/W RθJC specification. The SRAF10100 C0G datasheet confirms this limit applies to all variants including standard and AEC-Q101-qualified SRAF10100H.

Does SRAF10100 C0G have AEC-Q101 qualification?

The SRAF10100 C0G itself is not AEC-Q101 qualified; however, the SRAF10100H variant - identical in electrical and thermal specs - is fully AEC-Q101 qualified. The "H" suffix denotes automotive-grade screening and test compliance. Engineers specifying SRAF10100 C0G for automotive use must select SRAF10100H to meet qualification requirements. Both share the same ITO-220AC package and marking code prefix.

What is the forward voltage of SRAF10100 C0G at 10A and 100°C junction temperature?

The SRAF10100 C0G forward voltage increases with temperature: while VF is 0.85V at 10A and 25°C, the datasheet does not specify a typ/max value at 100°C. However, based on typical Schottky characteristics and curve Fig.4, VF at 10A/100°C is estimated between 0.72V and 0.78V. For design-critical thermal analysis, engineers should reference the SRAF10100 C0G forward characteristic curves rather than extrapolate from room-temperature data.

Is the ITO-220AC package of SRAF10100 C0G electrically isolated?

Yes, the ITO-220AC package used for SRAF10100 C0G features an electrically isolated metal tab, allowing direct mounting to a grounded heatsink without additional insulation. This isolation is confirmed in the Mechanical Data section and package outline drawings. The tab is rated for dielectric strength per UL standards and supports safe thermal management in high-voltage secondary-side applications where creepage/clearance constraints exist.

What is the reverse leakage current of SRAF10100 C0G at 100V and 125°C?

At 100V reverse voltage and 125°C junction temperature, the SRAF10100 C0G exhibits a maximum reverse leakage current (IR) of 5 mA, as specified in the Electrical Specifications table. This value reflects worst-case behavior under elevated thermal stress and is critical for standby power budgeting in always-on systems. The SRAF10100 C0G maintains lower leakage (100 µA) at 25°C, demonstrating strong temperature stability relative to silicon alternatives.
