Taiwan Semiconductor Corporation TS10K100H

Overview

TS10K100H from Taiwan Semiconductor is a 10A, 1000V standard quad bridge rectifier in TS4K package, with 150A surge rating, 2.3°C/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive-grade reliability. It delivers low forward voltage (1.1V @ 10A, 25°C) and ultra-low reverse leakage (<10µA @ 25°C), used in high-efficiency AC/DC front-ends of industrial SMPS and automotive infotainment power supplies.

For engineers reviewing the TS10K100H datasheet, TS10K100H pinout, TS10K100H application, or TS10K100H equivalent, key selection criteria include peak reverse voltage margin, surge current handling under 8.3ms half-sine stress, thermal performance in convection-cooled PCB layouts, and AEC-Q101 compliance for under-hood deployment.

Technical Context

This device integrates four silicon diodes in a single-phase bridge configuration, enabling full-wave rectification without external interconnects. Its TS4K package features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Rated for continuous operation up to 150°C junction temperature, it supports derated forward current down to ~7.5A at 100°C case temperature per the forward current derating curve. Reverse recovery is not specified - confirming non-fast-recovery, standard switching behavior suitable for line-frequency and low-kHz SMPS topologies.

FAQ

What is the maximum junction temperature rating for TS10K100H?

The TS10K100H has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows continuous operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. Derating curves confirm usable forward current down to ~7.5A at 100°C case temperature. Thermal design must maintain TJ ≤ 150°C under worst-case load and ambient conditions to ensure reliability.

Does TS10K100H have AEC-Q101 qualification, and what does that cover?

Yes, TS10K100H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code and confirmed in the Mechanical Data section. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating suitability for automotive electronic modules. The TS10K100H qualification applies specifically to the TS4K package variant and supports use in infotainment, body control, and ADAS power supplies.

What is the forward voltage drop of TS10K100H at rated current?

The TS10K100H exhibits a maximum forward voltage (VF) of 1.1 V at 10 A and 25°C junction temperature, per the Electrical Specifications table. At elevated temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics. This value directly determines conduction loss: at 10 A, dissipation is ~11 W, making thermal management via PCB copper area or heatsinking essential for sustained operation.

How does the TS4K package of TS10K100H compare to TO-220AC in thermal performance?

The TS4K package of TS10K100H achieves a junction-to-case thermal resistance (RθJC) of 2.3°C/W, outperforming typical TO-220AC bridge rectifiers like VS-10B100 (3.0°C/W). This 23% improvement enables lower temperature rise for the same power dissipation, allowing denser PCB layouts or reduced heatsink size. The TS4K's molded plastic case also supports automated SMT placement, unlike TO-220AC which requires through-hole or manual mounting.

Is TS10K100H halogen-free, and which standard does it meet?

Yes, TS10K100H is halogen-free per IEC 61249-2-21, as stated in the Features section. This means total bromine and chlorine content is below 900 ppm each, and total halogens (Br + Cl) are below 1500 ppm - satisfying strict environmental requirements for consumer electronics sold in the EU, Japan, and other regulated markets. This specification applies to the molding compound and is verified by material certification.
