Taiwan Semiconductor Corporation TS6KL60H

Overview

TS6KL60H from Taiwan Semiconductor is a 6A, 600V AEC-Q101-qualified standard bridge rectifier in KBJL package, featuring glass-passivated junctions, 150A surge capability, and UL Recognized File #E-326243 - used in compact switching-mode power supplies and automotive-grade AC/DC adapters.

For engineers reviewing the TS6KL60H datasheet, TS6KL60H pinout, TS6KL60H application, or TS6KL60H equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (6 A), junction-to-case thermal resistance (2 °C/W), AEC-Q101 qualification status, and KBJL mechanical compatibility with high-density PCB layouts.

Technical Context

The TS6KL60H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad arrangement, enabling direct AC-to-DC conversion without external interconnection. Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25°C) and robustness against humidity and contamination.

Thermal performance is defined for mounting on a 4" × 6" × 0.25" aluminum plate, delivering R_θJA = 7 °C/W and R_θJC = 2 °C/W - critical for sustained 6 A conduction in thermally constrained lighting and adapter designs where case temperature must remain below 150°C.

Key Specifications

Pinout & Package

FAQ

What is the peak repetitive reverse voltage rating for TS6KL60H?

The TS6KL60H has a peak repetitive reverse voltage (V_RRM) rating of 600 V. This value defines the maximum sinusoidal reverse voltage the device can block repeatedly without breakdown. It is measured under standard test conditions (T_A = 25°C) and forms the basis for selecting appropriate input voltage derating margins in AC line applications. The TS6KL60H is part of a family spanning 600 V to 1000 V, with TS6KL60H specifically designated for 600 V systems.

Is TS6KL60H suitable for automotive applications?

Yes, TS6KL60H is explicitly AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and electrostatic discharge per the AEC-Q101 standard. Its rated junction temperature range (−55°C to +150°C), UL Recognition #E-326243, and halogen-free construction make TS6KL60H suitable for automotive front-end rectification in modules such as on-board chargers and body control units.

What is the thermal resistance from junction to case for TS6KL60H?

The junction-to-case thermal resistance (R_θJC) of TS6KL60H is 2.0 °C/W, measured under standardized conditions using a 4" × 6" × 0.25" aluminum plate. This low value enables efficient heat transfer from the die to the PCB or heatsink, supporting continuous 6 A operation without excessive junction temperature rise. Designers must maintain proper mechanical mounting torque (≤0.56 N·m) to preserve this thermal performance in the TS6KL60H.

Does TS6KL60H have UL recognition?

Yes, TS6KL60H is UL Recognized under File #E-326243, confirming compliance with UL 60950-1 and UL 62368-1 standards for information technology and audio/video equipment. This recognition validates its suitability for use in end products requiring safety agency approval, reducing time and cost for system-level certification. The UL mark applies specifically to the TS6KL60H variant, not the entire TS6KLx family.

What does the "H" suffix indicate in TS6KL60H?

The "H" suffix in TS6KL60H denotes AEC-Q101 qualification - a mandatory requirement for discrete semiconductors used in automotive electronic systems. This distinguishes TS6KL60H from the non-qualified TS6KL60 variant. Both share identical electrical ratings (6 A, 600 V), package (KBJL), and thermal specs, but only TS6KL60H carries the AEC-Q101 validation required for automotive design-in and PPAP submission.
