Taiwan Semiconductor Corporation TS6K40H

Overview

TS6K40H from Taiwan Semiconductor is a 6A, 400V AEC-Q101-qualified standard quad bridge rectifier in TS4K package, with typical reverse leakage <0.1µA at 25°C, 150A surge capability, and 3°C/W junction-to-case thermal resistance-used in automotive-grade AC/DC front-end stages of SMPS and TV power supplies.

For engineers reviewing the TS6K40H datasheet, TS6K40H pinout, TS6K40H application, or TS6K40H equivalent, key selection criteria include its AEC-Q101 qualification, 400V repetitive peak reverse voltage, 6A average forward current rating, TS4K mechanical outline, and compatibility with J-STD-002 soldering processes.

Technical Context

The TS6K40H integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. Its design supports high-reliability operation up to 150°C junction temperature and meets JESD201 Class 2 whisker resistance requirements.

Thermal performance is defined by a 3°C/W junction-to-case resistance, enabling efficient heat transfer to heatsink-mounted PCBs. The device operates with ≤1.1V forward voltage at 6A/25°C and maintains <5µA reverse current at rated 400V reverse voltage and 25°C ambient.

Key Specifications

Pinout & Package

TS6K40H uses the TS4K molded plastic package (UL 94V-0 rated), with 4 external terminals: two AC inputs (±), one common anode (+), and one common cathode (–). Polarity is marked on the case per standard bridge orientation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with GBU6K and DF005M, TS6K40H uniquely combines AEC-Q101 qualification, ultra-low leakage (<5µA), and optimized surface-mount thermal path (3°C/W) - making it the preferred choice for next-generation automotive and high-reliability industrial rectification where space, efficiency, and qualification rigor intersect.

Availability

TS6K40H is available at Aetrix Electronics and suitable for automotive infotainment systems, industrial PLC power supplies, and flat-panel TV main boards requiring stable component supply, long-lifecycle assurance, and AEC-Q101-compliant sourcing.

Supply support for TS6K40H includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving automotive, industrial, and consumer markets since 1979.

The TS6K series was developed specifically for high-reliability AC/DC rectification in harsh-environment applications, emphasizing AEC-Q101 compliance, low leakage, and robust thermal performance in surface-mount packages.

FAQ

What is the marking code for TS6K40H?

The TS6K40H is marked "TS6K40" on the device body, followed by green compound indicator (G), date code (YWW), and factory code (F), per the official TS4K package marking diagram. This distinguishes it from other variants like TS6K60H or TS6K80H within the same family and confirms its 400V VRRM rating and AEC-Q101 qualification.

Does TS6K40H support lead-free reflow soldering?

Yes, TS6K40H features matte tin-plated leads qualified per J-STD-002 for lead-free soldering processes. Its terminals withstand peak reflow temperatures up to 260°C for 10 seconds, ensuring compatibility with standard Pb-free assembly lines while maintaining intermetallic integrity and whisker resistance per JESD201 Class 2.

What is the maximum mounting torque for TS6K40H?

The maximum recommended mounting torque for TS6K40H is 8.17 in-lbs (0.92 N·m), as specified in the Mechanical Data section. Exceeding this value risks cracking the TS4K molded case or damaging internal wire bonds, especially during heatsink attachment or mechanical stress testing in automotive or industrial environments.

How does TS6K40H differ from TS6K40 (non-H) version?

The "H" suffix in TS6K40H explicitly denotes AEC-Q101 qualification, including extended temperature cycling, high-temperature reverse bias, and accelerated life testing per automotive stress standards. The base TS6K40 lacks this qualification and is intended for commercial applications only - both share identical electrical specs and TS4K packaging.

Is TS6K40H compliant with halogen-free standards?

Yes, TS6K40H conforms to IEC 61249-2-21 for halogen-free printed wiring board materials, with bromine and chlorine content each below 900 ppm and total halogens below 1500 ppm. This supports environmentally responsible manufacturing and end-of-life processing in accordance with global regulatory frameworks.
