Taiwan Semiconductor Corporation TS4K60

Overview

TS4K60 from Taiwan Semiconductor is a 4A, 600V repetitive peak reverse voltage (V_RRM) standard quad bridge rectifier in TS4K package, with 120A surge capability (I_FSM), 5.5°C/W junction-to-case thermal resistance, and <10µA reverse current at 25°C - used in AC/DC front-end stages of switching mode power supplies.

For engineers reviewing the TS4K60 datasheet, TS4K60 pinout, TS4K60 application, or TS4K60 equivalent, key selection criteria include V_RRM = 600V, I_F = 4A continuous, thermal performance (R_θJC = 5.5°C/W), AEC-Q101 qualification availability, and TS4K through-hole package compatibility with high-surge SMPS designs.

Technical Context

The TS4K60 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. It operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge pulses up to 120A.

Its electrical behavior is defined by forward voltage ≤1.1V at 4A/25°C, reverse leakage ≤10µA per diode at rated V_R and 25°C, and fusing I²t rating of 60A²s - enabling robust operation in line-powered adapters and TV power supplies without external snubbing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with VS-GBPC406 and GBPC406, the TS4K60 offers superior surge robustness (120A vs. 100–100A) and lower thermal resistance (5.5°C/W vs. 7.0–6.5°C/W), enabling smaller PCB thermal relief in space-constrained 4A SMPS designs.

Availability

TS4K60 is available at Aetrix Electronics and suitable for switching mode power supplies, AC adapters, and television power modules requiring stable component supply and long-lifecycle support.

Supply support for TS4K60 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The TS4K series was designed specifically for high-reliability, high-surge AC/DC front-end rectification in cost-sensitive, high-volume power supplies - balancing thermal performance, safety certification, and manufacturability in TS4K through-hole format.

FAQ

What is the maximum junction temperature rating for TS4K60?

The TS4K60 has a maximum junction temperature (T_J) rating of +150°C, with an operating range from -55°C to +150°C. This rating is critical for thermal design in enclosed power supplies where ambient temperatures exceed 70°C. The TS4K60 must be mounted on adequate copper area or heatsink to maintain junction temperature within limits during 4A continuous conduction. Thermal derating curves in the TS4K60 datasheet define safe operating current versus case temperature.

Does TS4K60 support automotive applications?

Yes - the TS4K60H variant is AEC-Q101 qualified for automotive applications, while the standard TS4K60 is not. The TS4K60H undergoes rigorous stress testing including temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D. For under-dash or infotainment power supplies requiring automotive qualification, TS4K60H must be specified; the base TS4K60 remains suitable for industrial and consumer use only.

What is the forward voltage drop of TS4K60 at rated current?

The TS4K60 exhibits a maximum forward voltage (V_F) of 1.1 V per diode at I_F = 4A and T_J = 25°C, measured under pulse conditions (PW = 0.3ms). At higher junction temperatures (e.g., 125°C), V_F decreases slightly due to negative temperature coefficient. This V_F value directly determines conduction losses: at 4A, total bridge loss is ~4.4 W (4 × 1.1 V × 1 A per diode path), influencing thermal design and efficiency targets in SMPS.

How is polarity marked on the TS4K60 package?

The TS4K60 uses standardized bridge rectifier polarity marking: the cathode bar (–) is printed adjacent to the DC– terminal, and the "+" symbol appears near the DC+ terminal. The AC input terminals (~) are unmarked but located diagonally opposite each other on the package outline. This marking aligns with JEDEC MO-127 and ensures correct orientation during manual or automated placement. Misorientation results in reversed DC output polarity and potential system damage.

What packaging options are available for TS4K60?

The TS4K60 is supplied in 20-piece tubes (standard packing), with no tape-and-reel or bulk options listed in official Taiwan Semiconductor documentation. Each tube is labeled with date code (YWW), factory code (F), and green compound indicator (G). For high-volume SMT lines requiring automation, customers should verify tube-to-feeder compatibility; for hand-soldering or low-volume prototyping, the tube format supports easy access and static-safe handling.
