Taiwan Semiconductor Corporation TS6KL60

Overview

TS6KL60 from Taiwan Semiconductor is a 6A, 600V standard quad bridge rectifier in KBJL package, featuring glass-passivated junctions, 150A surge capability, and UL recognition (E-326243), designed for compact switching-mode power supplies and lighting adapters.

For engineers reviewing the TS6KL60 datasheet, TS6KL60 pinout, TS6KL60 application, or TS6KL60 equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (6 A), thermal resistance (R_θJA = 7 °C/W), AEC-Q101 qualification availability, and KBJL mechanical compatibility in space-constrained industrial and consumer power designs.

Technical Context

The TS6KL60 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25°C) and high reliability under thermal cycling.

Rated for continuous operation up to 150°C junction temperature and capable of withstanding 150 A non-repetitive surge (8.3 ms half-sine), the device delivers robust performance in high-efficiency AC/DC conversion where low forward voltage drop (max 1.05 V at 3 A, 25°C) reduces conduction losses.

FAQ

What is the maximum junction temperature rating for the TS6KL60?

The TS6KL60 has a maximum junction temperature (T_J) rating of +150°C, allowing continuous operation in high-ambient environments such as enclosed power supplies or motor drive control boards. This rating is validated per absolute maximum ratings table in the E2104 datasheet and supports derating curves up to 150°C ambient when mounted on specified aluminum plate. Thermal design must respect R_θJA = 7 °C/W to avoid exceeding this limit.

Does the TS6KL60 have UL recognition, and what is the file number?

Yes, the TS6KL60 is UL Recognized under file #E-326243, confirming compliance with UL 60747-1 for discrete semiconductors. This recognition applies to the standard TS6KL60 and TS6KL60H variants and covers flammability (UL 94V-0), terminal solderability (J-STD-002), and whisker resistance (JESD 201 Class 2). The UL mark appears on official TSC packaging and documentation.

What is the forward voltage specification for the TS6KL60, and under what test conditions?

The TS6KL60 has a maximum forward voltage (V_F) of 1.05 V per diode at I_F = 3 A and T_J = 25°C, measured using a 0.3 ms pulse width. This value reflects worst-case conduction loss in one leg of the bridge and is critical for calculating total rectifier power dissipation. At elevated temperatures or higher currents, V_F increases slightly, as shown in Figure 4 of the E2104 datasheet.

Is the TS6KL60 available in an AEC-Q101 qualified version, and how is it identified?

Yes, the AEC-Q101 qualified version of the TS6KL60 is designated TS6KL60H. It undergoes additional stress testing per AEC-Q101 Rev D, including HTSL, TC, and UHAST, and carries the same KBJL package and electrical specifications. The "H" suffix in the ordering code explicitly identifies this automotive-grade variant, which is documented in the E2104 revision and supported by TSC's automotive product change notifications.

What is the surge current rating of the TS6KL60, and how does it compare across time durations?

The TS6KL60 supports 150 A peak forward surge current (I_FSM) for 8.3 ms (one half-cycle of 60 Hz), and 280 A for 1.0 ms. These values are defined in the Absolute Maximum Ratings table and reflect non-repetitive capability under short-duration overload. The corresponding I²t rating is 93.37 A²s, enabling precise fuse selection and overcurrent protection coordination in AC input stages.
