Taiwan Semiconductor Corporation TS4K60H

Overview

TS4K60H from Taiwan Semiconductor is a 4A, 600V 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 AC-to-DC front-end rectification stage in compact power supplies.

For engineers reviewing the TS4K60H datasheet, TS4K60H pinout, TS4K60H application, or TS4K60H equivalent, key selection criteria include repetitive peak reverse voltage (600V), forward current rating (4A), thermal resistance (5.5°C/W), AEC-Q101 compliance status, and TS4K mechanical footprint compatibility.

Technical Context

The TS4K60H integrates four silicon diodes in a single-phase bridge configuration with common-cathode/common-anode topology. Its 600V V_RRM and 120A I_FSM support high-energy transient handling in offline SMPS inputs.

Thermal performance is defined by a junction-to-case resistance of 5.5°C/W and a maximum junction temperature of +150°C, enabling operation under sustained 4A average forward current with appropriate heatsinking.

FAQ

What is the peak repetitive reverse voltage rating for TS4K60H?

The TS4K60H has a peak repetitive reverse voltage (V_RRM) rating of 600 V. This value is specified per diode within the quad bridge configuration and defines the maximum AC input voltage the device can block reliably during normal operation. It provides sufficient margin for universal-input SMPS designs operating from 90–264V_RMS, where peak line voltage reaches approximately 373V.

Is TS4K60H qualified for automotive applications?

Yes, TS4K60H is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification confirms that the device has passed stress tests for temperature cycling, humidity, mechanical shock, and other conditions defined in the AEC-Q101 standard for discrete semiconductors used in automotive electronics. TS4K60H is suitable for engine control units, body electronics, and infotainment power supplies.

What is the forward voltage drop of TS4K60H at rated current?

At 4A forward current and 25°C junction temperature, the TS4K60H exhibits a maximum forward voltage drop (V_F) of 1.1 V per diode. This value is measured under pulsed conditions (PW = 0.3ms) and directly impacts conduction losses in the rectifier stage. At lower currents (e.g., 2A), V_F drops to ≤1.0 V, improving efficiency in light-load operation.

Does TS4K60H have UL recognition?

Yes, TS4K60H carries UL Recognition under file number E-326243. This certification verifies compliance with UL 60950-1 and UL 62368-1 safety standards for information technology and audio/video equipment. UL recognition supports faster end-product safety certification and is required for many commercial and industrial power supply approvals.

What is the thermal resistance from junction to case for TS4K60H?

The junction-to-case thermal resistance (R_θJC) of TS4K60H is 5.5°C/W, measured under standard test conditions. This parameter enables accurate thermal modeling when the device is mounted to a heatsink or metal chassis. Combined with its +150°C maximum junction temperature, it supports reliable operation at full 4A load with proper mechanical thermal interface design.
