Taiwan Semiconductor Corporation TSF20H60C

Overview

TSF20H60C from Taiwan Semiconductor is a dual common-cathode trench Schottky rectifier rated for 60 V reverse voltage, 20 A total forward current (10 A per diode), and 200 A surge capability at 8.3 ms; it delivers low forward voltage (0.56 V typ. @ 10 A, 25°C) and operates up to 150°C junction temperature in SMPS secondary-side rectification.

For engineers reviewing the TSF20H60C datasheet, TSF20H60C pinout, TSF20H60C application, or TSF20H60C equivalent, key selection factors include thermal resistance (R_θJC = 3.4 °C/W per diode), high-temperature reverse leakage (29 mA @ 125°C), dual-die configuration in ITO-220AB, and RoHS/halogen-free compliance for industrial power designs.

Technical Context

The TSF20H60C integrates two independent Schottky die in a single ITO-220AB package with shared cathode terminal, enabling synchronous or interleaved rectification topologies. Its trench-based structure ensures stable VF across temperature and low R_θJC for efficient heat transfer to heatsinks.

Designed for high-frequency switching applications, it exhibits 754 pF junction capacitance at 4 V reverse bias and supports pulse surge currents up to 600 A (1 ms), making it suitable for transient-heavy DC/DC outputs and adapter secondary rails where low conduction loss and fast recovery are critical.

FAQ

What is the maximum junction temperature rating for the TSF20H60C?

The TSF20H60C has a maximum junction temperature (T_J) of +150°C, verified across its full operating range from –55°C to +150°C. This rating is supported by its trench Schottky structure and low R_θJC of 3.4 °C/W per diode. The TSF20H60C maintains stable forward voltage and leakage performance up to this limit, making it suitable for enclosed or high-ambient environments such as LED drivers and industrial power modules.

Does the TSF20H60C have insulated leads for chassis mounting?

Yes, the TSF20H60C uses the ITO-220AB package, which provides electrical isolation between the metal tab (cathode) and the two anode leads. This insulation eliminates the need for separate insulating washers or pads when mounting directly to a grounded heatsink or chassis. The TSF20H60C's ITO-220AB construction meets UL 94V-0 flammability standards and supports safe, simplified mechanical integration in Class I power supplies.

What is the forward voltage of the TSF20H60C at 10 A and 125°C?

The TSF20H60C exhibits a typical forward voltage of 0.52 V and a maximum of 0.62 V at 10 A and 125°C per diode, as specified in its electrical characteristics table. This low, temperature-stable VF is enabled by its patented trench Schottky technology. The TSF20H60C's performance at elevated temperature ensures consistent efficiency in thermally stressed applications like server PSUs or outdoor LED drivers.

Can the TSF20H60C replace two separate 10 A Schottky diodes?

Yes, the TSF20H60C integrates two independent 10 A Schottky dies in a single ITO-220AB package with a shared cathode, allowing direct replacement of two discrete 10 A Schottky diodes. Its dual-anode layout preserves circuit flexibility while reducing PCB area, solder joints, and thermal interface complexity. The TSF20H60C maintains individual die ratings (I_F = 10 A per diode, I_FSM = 200 A per diode), ensuring functional equivalence without derating.

Is the TSF20H60C compliant with halogen-free and RoHS requirements?

Yes, the TSF20H60C is both RoHS-compliant and halogen-free in accordance with IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating meeting J-STD-002 solderability standards. These certifications are confirmed in the official Taiwan Semiconductor datasheet for TSF20H60C and support compliance for CE, UL, and other regional safety marks.
