Taiwan Semiconductor Corporation TS4K100H

Overview

TS4K100H from Taiwan Semiconductor is a 4A, 1000V rated standard quad bridge rectifier in TS4K package, featuring 120A surge capability, <10µA reverse current at 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as the primary AC-to-DC conversion stage in high-voltage offline power supplies.

For engineers reviewing the TS4K100H datasheet, TS4K100H pinout, TS4K100H application, or TS4K100H equivalent, key selection criteria include peak reverse voltage (1000V), forward current rating (4A), thermal resistance (5.5°C/W), AEC-Q101 compliance status, and TS4K mechanical footprint compatibility with PCB mount requirements.

Technical Context

This device integrates four silicon diodes in a single-phase bridge configuration with common-cathode and common-anode terminals externally accessible. Its 1000V V_RRM supports universal input (85–265V_AC) SMPS designs operating up to 150°C junction temperature.

The TS4K100H delivers 120A non-repetitive surge current (8.3ms half-sine) and maintains ≤1.1V forward voltage at 4A/25°C, enabling efficient rectification with minimal conduction loss and low thermal impedance (R_θJC = 5.5°C/W).

Key Specifications

Pinout & Package

TS4K100H uses the TS4K molded plastic package (UL 94V-0), measuring 22.0 × 17.5 × 5.5 mm, with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

FAQ

What is the maximum junction temperature rating for TS4K100H?

The TS4K100H has a maximum junction temperature (T_J) of +150°C, allowing operation in thermally demanding environments such as enclosed power supplies and automotive under-hood applications. This rating is validated per AEC-Q101 stress testing and supported by its 5.5°C/W junction-to-case thermal resistance. The TS4K100H must be mounted on a heatsink or copper pour to sustain continuous 4A current at elevated ambient temperatures.

Does TS4K100H meet automotive reliability standards?

Yes, TS4K100H is explicitly AEC-Q101 qualified, as confirmed in the ordering code suffix "H" and documented in Taiwan Semiconductor's F2101 datasheet revision. This qualification covers temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-making TS4K100H suitable for automotive infotainment, display, and body control modules where long-term reliability is mandatory.

What is the reverse leakage current specification for TS4K100H at 125°C?

At T_J = 125°C and rated reverse voltage, the TS4K100H exhibits a maximum reverse current (I_R) of 500 µA per diode, as specified in the Electrical Specifications table. This value is measured using a 30ms pulse test and reflects real-world performance in high-temperature power supply operation. The TS4K100H maintains low leakage to minimize standby power loss even under thermal stress.

Is TS4K100H pin-compatible with other TS4K-series rectifiers like TS4K40H or TS4K60H?

Yes, all TS4K-series rectifiers-including TS4K40H, TS4K60H, TS4K80H, and TS4K100H-share identical TS4K package dimensions, pinout, and terminal configuration. Only the peak reverse voltage rating differs (400V to 1000V). This allows direct substitution in existing layouts when higher voltage margin is required, provided thermal and surge requirements remain within design margins for the TS4K100H.

What safety certifications does TS4K100H hold?

TS4K100H is UL Recognized under file #E-326243 and complies with RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. These certifications apply to the device itself and support end-product safety listings (e.g., UL/EN 62368-1) without requiring additional component-level retesting. The TS4K100H is not intended for medical or life-sustaining applications.
