Taiwan Semiconductor Corporation TS10K40H

Overview

TS10K40H from Taiwan Semiconductor is a 10A, 400V AEC-Q101-qualified standard quad bridge rectifier in TS4K package, with typical reverse leakage <0.1µA at 25°C and 150A surge rating (8.3ms), used in AC/DC front-end stages of industrial SMPS and display power supplies.

For engineers reviewing the TS10K40H datasheet, TS10K40H pinout, TS10K40H application, or TS10K40H equivalent, key selection criteria include repetitive peak reverse voltage (400V), forward current rating (10A), junction-to-case thermal resistance (2.3°C/W), AEC-Q101 qualification status, and TS4K mechanical compatibility for high-reliability board-level integration.

Technical Context

The TS10K40H integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling direct AC-to-DC conversion without external interconnects. Its TS4K molded package supports surface-mount assembly with matte tin-plated leads compliant to J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Thermally, it delivers 2.3°C/W junction-to-case resistance and operates across –55°C to +150°C junction temperature range. Electrical behavior is defined by 1.0V max forward voltage at 5A/25°C and ≤10µA reverse current at rated 400V V_RRM and 25°C.

FAQ

What is the maximum junction temperature rating for TS10K40H?

The TS10K40H has a maximum junction temperature (T_J) rating of +150°C and a minimum of –55°C. This wide operating range supports deployment in automotive under-hood environments and industrial enclosures without forced cooling. The device's 2.3°C/W junction-to-case thermal resistance allows effective heat transfer to an external heatsink or PCB copper plane when operating at its full 10A rated current. Derating curves in the TS10K40H datasheet specify usable current versus case temperature.

Does TS10K40H meet automotive reliability standards?

Yes, TS10K40H is explicitly qualified to AEC-Q101 for discrete semiconductors, covering stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST). This qualification confirms suitability for automotive power supply applications such as infotainment systems and digital instrument clusters. The "H" suffix in TS10K40H denotes this AEC-Q101 status, distinguishing it from non-automotive variants like TS10K40.

What does the marking code "TS10K40" indicate on the TS10K40H device body?

The marking code "TS10K40" on the TS10K40H indicates its base part number: "TS" = Taiwan Semiconductor, "10" = 10A average forward current, "K" = bridge rectifier family, "40" = 400V repetitive peak reverse voltage (V_RRM). The "H" suffix is not marked on the device but appears only in the ordering code to denote AEC-Q101 qualification. Additional markings include date code (YWW), factory code (F), and green compound indicator (G).

How does TS10K40H compare to TS10K60H in terms of voltage rating and interchangeability?

TS10K40H is rated for 400V V_RRM, while TS10K60H is rated for 600V. They share identical package (TS4K), current rating (10A), thermal resistance (2.3°C/W), and AEC-Q101 qualification. However, they are not interchangeable without circuit review: substituting TS10K40H for TS10K60H risks reverse breakdown in designs with >400V peak line voltage or poor input filtering. Always verify peak reverse stress against the specific V_RRM of the TS10K40H before replacement.

Is TS10K40H compliant with RoHS and halogen-free requirements?

Yes, TS10K40H is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below RoHS thresholds. The matte tin-plated leads meet J-STD-002 solderability requirements for lead-free reflow processes. These compliance attributes are documented in Taiwan Semiconductor's official material declarations and are verified through third-party testing.
