Taiwan Semiconductor Corporation TS6K80H

Overview

TS6K80H from Taiwan Semiconductor is a 6A, 800V rated standard quad bridge rectifier in TS4K package, with 150A surge capability, 1.1V max forward voltage at 6A/25°C, and <5µA reverse leakage at 25°C - used for AC-DC conversion in compact SMPS and TV power supplies.

For engineers reviewing the TS6K80H datasheet, TS6K80H pinout, TS6K80H application, or TS6K80H equivalent, key selection criteria include peak reverse voltage (800V), thermal resistance (3°C/W), AEC-Q101 qualification, RoHS/halogen-free compliance, and TS4K mechanical compatibility with PCB-mounting constraints.

Technical Context

This device integrates four silicon diodes in a single-phase bridge configuration, enabling full-wave rectification without external interconnects. Its 800V V_RRM supports universal input (85–265VAC) designs, while the 3°C/W R_θJC enables efficient heat transfer to heatsink or PCB copper.

The TS6K80H meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements, with matte tin-plated leads solderable per J-STD-002. Polarity is marked on the case, and mounting torque must not exceed 8.17 in-lbs.

FAQ

What is the maximum junction temperature rating for TS6K80H?

The TS6K80H has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in sealed enclosures or high-ambient environments such as LED drivers and industrial power supplies. The TS6K80H maintains specified electrical performance within this range, and derating curves in the datasheet define safe current limits above 25°C ambient.

Does TS6K80H require a heatsink in typical 6A applications?

At 6A continuous current and 25°C ambient, the TS6K80H dissipates approximately 6.6W (based on V_F ≤1.1V). With its 3°C/W junction-to-case thermal resistance, a 20°C temperature rise occurs without heatsinking - acceptable only if case temperature remains below 130°C. For sustained operation above 40°C ambient or in enclosed spaces, a heatsink or copper pour is recommended to maintain TS6K80H junction temperature within limits.

Is TS6K80H pin-compatible with other TS6Kx variants?

Yes, all TS6Kx (x = 40, 60, 80, 100) variants share identical TS4K package dimensions, pinout, and terminal assignments. The only difference is rated V_RRM: TS6K80H is 800V, while TS6K100H is 1000V. This allows design reuse across input voltage ranges without layout changes - provided the selected variant meets the system's peak reverse voltage requirement.

What does the "H" suffix indicate in TS6K80H?

The "H" suffix in TS6K80H denotes full AEC-Q101 qualification, including stress testing for temperature cycling, high-temperature reverse bias (HTRB), and high-temperature gate bias (HTGB). This distinguishes it from standard TS6K80 (non-H), which lacks automotive reliability validation. TS6K80H is intended for automotive cabin electronics, ADAS auxiliary supplies, and industrial equipment requiring extended lifetime under thermal and electrical stress.

How does TS6K80H compare to TS6K80 in terms of electrical performance?

TS6K80H and TS6K80 share identical absolute maximum ratings, electrical specifications (V_F, I_R, I_FSM, etc.), and thermal characteristics. The sole functional difference is AEC-Q101 qualification: TS6K80H undergoes additional reliability screening per automotive standards, while TS6K80 is intended for commercial/industrial use. No electrical parameter deviation exists between the two versions.
