Product details

Overview

TS20K100-T from Taiwan Semiconductor is a 20A, 1000V standard bridge rectifier in TS4K in-line package, featuring ultra-low leakage reverse current (≤5 μA at 25°C), 220A surge capability, and 1.2 °C/W junction-to-case thermal resistance - deployed in on-board chargers and industrial AC–DC power supplies.

For engineers reviewing the TS20K100-T datasheet, TS20K100-T pinout, TS20K100-T application, or TS20K100-T equivalent, key selection criteria include rated repetitive peak reverse voltage (1000 V), forward voltage (1.05 V max at 10 A/25°C), thermal resistance (R_θJC = 1.2 °C/W), and UL recognition (E-326243).

Technical Context

The TS20K100-T integrates four silicon diodes in a single-phase full-wave bridge configuration with in-line terminal layout. It supports continuous forward current up to 20 A and withstands repetitive reverse voltages up to 1000 V, with fusing I²t rating of 200 A²s for transient surge protection.

Thermal performance is specified with R_θJC = 1.2 °C/W and R_θJL = 1.3 °C/W when mounted on an aluminum heat sink (4″ × 6″ × 0.25″), enabling stable operation up to T_J = 150 °C under rated load conditions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-20B100	Same 20 A / 1000 V rating; TO-220AC package; R_θJC = 1.5 °C/W; no UL file listed.	Requires different mounting hardware and thermal interface; lacks UL recognition for safety-critical systems.	Select when TO-220 footprint is preferred and UL compliance is not mandated.
ON Semiconductor GBPC2010	20 A / 1000 V; GBPC package; R_θJC = 1.4 °C/W; I_R = 10 μA max (higher leakage).	Higher reverse leakage may impact standby efficiency; GBPC mechanical outline differs from TS4K.	Choose if GBPC board space and lead spacing match existing layout; verify leakage tolerance in low-power modes.

Compared with VS-20B100 and GBPC2010, the TS20K100-T offers superior thermal resistance (1.2 °C/W), lower leakage (≤5 μA), and UL recognition - making it optimal for compact, safety-certified, thermally constrained AC–DC front ends.

FAQ

What is the maximum repetitive peak reverse voltage rating for TS20K100-T?

The TS20K100-T has a maximum repetitive peak reverse voltage (V_RRM) rating of 1000 V. This value is explicitly specified in the Absolute Maximum Ratings table for the TS20K100-T variant and defines the highest reverse voltage the device can block continuously without breakdown. It is confirmed across all official documentation versions (A2208) and distinguishes TS20K100-T from lower-voltage variants like TS20K40-T (400 V) and TS20K80-T (800 V).

Does TS20K100-T have UL recognition, and what is the file number?

Yes, the TS20K100-T is UL Recognized under File # E-326243. This recognition applies to the entire TS20K40-T through TS20K100-T family and confirms compliance with UL 60747-4 for discrete semiconductor devices. The UL mark supports end-product safety certification in North America and is documented in the FEATURES section of the official datasheet revision A2208.

What is the forward voltage drop of TS20K100-T at rated current and temperature?

The TS20K100-T exhibits a maximum forward voltage (V_F) of 1.05 V per diode at 10 A and 25°C, as specified in the Electrical Specifications table. At elevated junction temperature (125°C), V_F drops to 0.88 V typical. These values are measured under pulsed conditions (PW = 0.3 ms) and reflect conduction losses critical for thermal design and efficiency calculations in the TS20K100-T application.

What is the thermal resistance from junction to case (R_θJC) for TS20K100-T?

The junction-to-case thermal resistance (R_θJC) for TS20K100-T is 1.2 °C/W, measured with the device mounted on a 4″ × 6″ × 0.25″ aluminum heat sink. This value is consistent across all TS20K variants and is listed in the Thermal Performance section of the datasheet (A2208). It enables precise heatsink sizing and thermal interface optimization in high-power TS20K100-T deployments.

Is TS20K100-T compliant with RoHS and halogen-free standards?

Yes, the TS20K100-T is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements appear in the FEATURES section of the official datasheet (A2208) and apply to the full TS20K series. The halogen-free status covers molding compound and internal materials, supporting environmental requirements for industrial and automotive electronics using TS20K100-T.
