Product details

Overview

TS4K60-A from Taiwan Semiconductor is a 4A, 600V standard quad bridge rectifier with glass-passivated junctions, UL Recognized (E-326243), RoHS- and halogen-free compliant, designed for high-reliability AC/DC conversion in compact PCB layouts.

For engineers reviewing the TS4K60-A datasheet, TS4K60-A pinout, TS4K60-A application, or TS4K60-A equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (4 A), surge capability (120 A @ 8.3 ms), thermal resistance (R_θJL = 7 °C/W), and TS4K package compatibility with standard through-hole mounting.

Technical Context

The TS4K60-A integrates four silicon diodes in a single-phase full-wave bridge configuration, optimized for switching-mode power supplies requiring stable conduction at up to 4 A average forward current and 600 V peak reverse blocking. Its glass-passivated junction ensures long-term reliability under thermal cycling and humidity stress.

Thermal performance is defined with R_θJC = 6 °C/W and R_θJA = 18 °C/W when mounted on a 2" × 3" × 0.25" aluminum heatsink; forward voltage is specified at 1.0 V max per diode (IF = 2 A, TJ = 25°C) and drops to 0.9 V at 125°C, supporting efficient operation across industrial temperature range (–55°C to +150°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Peak reverse voltage rating; determines maximum AC input voltage the device can block safely in bridge topology.
I_F	4 A - Average forward current; defines continuous DC output capability in SMPS and adapter designs.
I_FSM	120 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during cold start.
R_θJL	7 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper or heatsink via leads.
V_F (per diode)	≤1.0 V @ 2 A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal design margin.
I_R (per diode)	≤10 µA @ 600 V, 25°C - Reverse leakage; critical for low-power standby efficiency and voltage hold-up stability.
T_J max	+150°C - Maximum junction temperature; allows operation in enclosed, high-ambient environments without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6K (ON Semiconductor)	Same 4 A / 600 V rating, GBU package (larger footprint, higher R_θJA = 25 °C/W)	Requires more PCB area; less suitable for ultra-compact adapters	Preferred where legacy GBU footprint exists and thermal margin is available.
KBU6K (Comchip)	Identical electrical specs; KBU package has different lead spacing and slightly higher I_FSM (130 A)	Compatible with same board thickness but requires revalidation of lead forming and solder joint geometry	Selected when dual-sourcing across multiple qualified suppliers is required.

Compared with TS4K60-A, GBU6K offers identical ratings but demands greater board real estate and exhibits higher thermal resistance, while KBU6K matches performance closely but uses a non-identical mechanical form factor-both require layout verification before substitution.

FAQ

What is the maximum repetitive peak reverse voltage rating for TS4K60-A?

The TS4K60-A has a maximum repetitive peak reverse voltage (V_RRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version D2103). It defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown, making TS4K60-A suitable for universal-input (85–265 VAC) applications where peak line voltage reaches ~375 V.

Does TS4K60-A meet RoHS and halogen-free requirements?

Yes, TS4K60-A is RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the FEATURES section of the datasheet (page 1). The halogen-free status applies to the molding compound and plating materials, supporting environmentally regulated end products including those sold in the EU and China.

What is the forward voltage drop specification for TS4K60-A at rated current?

TS4K60-A specifies a maximum forward voltage (V_F) of 1.0 V per diode at I_F = 2 A and T_J = 25°C, with a typical value of 0.9 V at 125°C. These values are listed in the Electrical Specifications table (page 2) and reflect conduction loss under standard test conditions using pulse-width-limited measurements (PW = 0.3 ms).

Can TS4K60-A be used as a direct replacement for TS4K40-A or TS4K80-A?

No-TS4K60-A is not a direct replacement for TS4K40-A or TS4K80-A due to differing V_RRM ratings (400 V and 800 V, respectively). While all share identical package (TS4K), pinout, and thermal characteristics, substituting across voltage grades requires validation of system-level surge immunity and safety margins. TS4K60-A must be selected based on actual peak reverse stress in the target application.

What is the junction-to-lead thermal resistance (R_θJL) of TS4K60-A?

The junction-to-lead thermal resistance (R_θJL) of TS4K60-A is 7 °C/W, as published in the Thermal Performance table (page 2). This value is measured under standardized conditions with proper lead mounting and reflects heat transfer efficiency from die to PCB-coupled leads-critical for estimating junction temperature rise in thermally constrained layouts.
