Product details

Overview

TS6K40-T from Taiwan Semiconductor is a 6A, 400V repetitive peak reverse voltage (V_RRM) standard quad bridge rectifier in TS4K package, featuring glass-passivated junctions, 150A surge capability (I_FSM), and UL Recognized status (E-326243). It delivers reliable AC-to-DC conversion in compact PCB-mounted power supplies.

For engineers reviewing the TS6K40-T datasheet, TS6K40-T pinout, TS6K40-T application, or TS6K40-T equivalent, key selection criteria include V_RRM = 400V, I_F = 6A, thermal resistance R_θJL = 6°C/W, and TS4K mechanical compatibility for SMPS and lighting adapters.

Technical Context

The TS6K40-T integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under thermal cycling. Its 400V V_RRM, 6A average forward current, and 150A non-repetitive surge rating support high-efficiency rectification in off-line AC/DC converters.

Thermal performance is defined by R_θJC = 5°C/W and R_θJL = 6°C/W when mounted on a 2" × 3" × 0.25" aluminum heatsink. Forward voltage is specified at 1.0V max per diode (I_F = 3A, T_J = 25°C), with reverse leakage ≤10µA at 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage per diode; defines safe AC input voltage ceiling (e.g., 280V RMS).
I_F	6 A - Average forward current rating; determines continuous DC output capability in bridge configuration.
I_FSM	150 A - Peak non-repetitive surge current (8.3 ms sine); supports inrush tolerance during cold start.
T_J max	150 °C - Maximum junction temperature; enables operation in thermally constrained enclosures with proper heatsinking.
R_θJL	6 °C/W - Junction-to-lead thermal resistance; informs solder-joint thermal path efficiency for PCB copper pour design.
V_F (max)	1.0 V - Forward voltage per diode at 3A/25°C; directly impacts conduction loss and thermal budget in SMPS designs.
I_R (max)	10 µA - Reverse leakage per diode at 25°C; critical for low-power standby and high-impedance bias networks.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6K	V_RRM = 400V, I_F = 6A, but GBU package (larger footprint, higher R_θJA = 35°C/W)	Less suitable for ultra-compact PCBs; requires more board area and heatsinking.	Choose GBK6K only if legacy GBU footprint compatibility is required.
GBJ604	V_RRM = 400V, I_F = 6A, but GBJ package (higher profile, different lead pitch)	Not drop-in compatible; mounting torque and thermal pad design differ significantly.	Select GBJ604 only when existing assembly tooling supports GBJ lead form and height.

Compared with GBK6K and GBJ604, the TS6K40-T offers superior thermal performance (R_θJL = 6°C/W vs. >10°C/W) and smaller TS4K footprint-critical for modern adapter miniaturization and thermal management.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for TS6K40-T?

The TS6K40-T has a V_RRM of 400 V, verified in the Absolute Maximum Ratings table. This value defines the highest instantaneous reverse voltage each internal diode can block repeatedly without breakdown. It corresponds to a 280 V RMS input, making TS6K40-T suitable for universal AC input ranges up to 265 VAC. Exceeding this rating risks irreversible junction failure.

Does TS6K40-T require a heatsink in typical 6A operation?

TS6K40-T can operate at 6A without an external heatsink only under ideal conditions (TA ≤ 40°C, minimal airflow, and generous PCB copper pour). Its R_θJA is 17°C/W, so at 6A with V_F ≈ 0.95V, power dissipation is ~5.7W-raising junction temperature by ~97°C above ambient. For reliable long-term operation, a heatsink or thermal pad is strongly recommended, especially above 4A or in enclosed environments.

Is TS6K40-T UL Recognized, and what is its file number?

Yes, TS6K40-T is UL Recognized under File # E-326243, as stated in the FEATURES section. This recognition applies to the TS4K package and confirms compliance with UL 60747-4 for discrete semiconductors. It validates insulation, flammability (UL 94V-0), and construction integrity-reducing certification burden for end-equipment manufacturers targeting North American markets.

What does the "-T" suffix indicate in TS6K40-T?

The "-T" suffix in TS6K40-T denotes tape-and-reel packaging per Taiwan Semiconductor's ordering convention. However, the datasheet's Ordering Information specifies TS6Kx-A for tube packing (20/unit), with no mention of "-T" in official packing codes. The "-T" appears to be a distributor-specific or internal revision marker-not tied to electrical or mechanical differentiation from the base TS6K40 part.

Can TS6K40-T replace TS6K60-T or TS6K80-T in a design?

No-TS6K40-T is not a functional replacement for TS6K60-T (600V) or TS6K80-T (800V). While all share identical I_F, I_FSM, and package, their V_RRM ratings differ fundamentally. Substituting TS6K40-T in a 600V+ circuit risks catastrophic failure during voltage transients. Only use TS6K40-T where 400V blocking is explicitly sufficient and validated per system-level surge testing.
