Taiwan Semiconductor Corporation SRF10100

Overview

SRF10100 from Taiwan Semiconductor is a 10A, 100V repetitive peak reverse voltage Schottky barrier rectifier in ITO-220AB package with dual-die configuration, 4.0°C/W junction-to-case thermal resistance, and 120A surge capability - used in high-efficiency DC/DC converters and industrial SMPS.

For engineers reviewing the SRF10100 datasheet, SRF10100 pinout, SRF10100 application, or SRF10100 equivalent, key selection criteria include its 100V V_RRM, 0.90V max forward voltage at 5A/25°C, 100µA max reverse leakage at rated VR/25°C, AEC-Q101 qualification option (SRF10100H), and ITO-220AB mechanical compatibility with heatsink mounting.

Technical Context

This Schottky rectifier uses guard ring structure for overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its dual-die configuration enables balanced current sharing and thermal distribution across the ITO-220AB case.

Rated for TJ = –55°C to +150°C operation, it delivers stable performance under transient surge conditions (8.3ms half-sine, 120A) and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

FAQ

What is the maximum junction temperature rating for SRF10100?

The SRF10100 has a maximum junction temperature (T_J) rating of +150°C, validated across its full operating range from –55°C to +150°C. This extended rating supports reliable operation in sealed enclosures and high-ambient industrial environments. The SRF10100 maintains specified electrical parameters up to this limit when thermal design respects its 4.0°C/W R_θJC and appropriate heatsinking is applied.

Does SRF10100 have AEC-Q101 qualification?

The base SRF10100 is not AEC-Q101 qualified; however, the SRF10100H variant is fully AEC-Q101 qualified per Version L2105 documentation. The "H" suffix denotes automotive-grade stress testing including temperature cycling, humidity bias, and mechanical shock. For automotive applications requiring qualification, SRF10100H must be specified - it shares identical electrical and thermal specs with the standard part.

What is the forward voltage specification for SRF10100 at 10A?

The SRF10100 datasheet specifies forward voltage only at I_F = 5A (0.90V max at 25°C); no guaranteed V_F is provided at 10A. However, typical curves show V_F ≈ 1.05V at 10A/25°C. Designers should use derating curves and thermal modeling to ensure V_F remains within acceptable loss budgets at full 10A load and elevated case temperatures.

Is the cathode tab of SRF10100 electrically isolated?

No - the cathode is internally connected to the metal tab in the ITO-220AB package of the SRF10100. The tab serves as both the common cathode terminal and primary thermal path. If circuit topology requires cathode isolation (e.g., floating output), an insulating washer and shoulder washer must be used during heatsink mounting, and creepage/clearance must be verified per end-equipment safety standards.

How does SRF10100 compare to SRF1060 in terms of reverse leakage?

At rated V_R and 25°C, SRF10100 specifies max I_R = 100 µA, while SRF1060 (60V version) specifies 500 µA. This reflects higher barrier height tuning in the 100V device, reducing leakage at higher reverse bias. At 100°C, SRF10100's leakage rises to ≤5 mA, whereas SRF1060 is rated ≤10 mA - confirming tighter control in the higher-voltage variant despite greater intrinsic leakage tendency.
