Taiwan Semiconductor Corporation TS25P01G

Overview

TS25P01G from Taiwan Semiconductor is a 25A, 50V standard quad bridge rectifier in TS-6P package, featuring glass passivated junctions, <0.1μA typical reverse leakage at 25°C, 350A peak surge capability, and UL Recognized (E-326243) construction - used in AC/DC front-end stages of compact SMPS and LED drivers.

For engineers reviewing the TS25P01G datasheet, TS25P01G pinout, TS25P01G application, or TS25P01G equivalent, key selection criteria include rated VRRM (50V), IF(25A), IFSM(350A), RθJC(0.6°C/W), and TS-6P mechanical compatibility with high-density PCB layouts.

Technical Context

The TS25P01G integrates four silicon diodes in a single-phase full-wave bridge configuration within a molded TS-6P case. Its glass passivated junction ensures stable reverse blocking and low IR drift over temperature.

Designed for conduction-limited thermal management, it delivers 25A average forward current with 0.6°C/W junction-to-case thermal resistance and supports 8.3ms half-sine surge events up to 350A without fusing (I²t = 508.37 A²s).

Key Specifications

Pinout & Package

TS-6P is a through-hole, 6-terminal molded package with integrated quad bridge topology. Pin assignments follow standard bridge rectifier layout: AC1, AC2 (AC inputs), + (anode common output), – (cathode common output), and two internal tie points (typically unused or internally connected).

Key Features

Applications

Equivalent & Alternatives

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

Compared with VS-25BQ050 and GBPC2505, the TS25P01G offers lower thermal resistance (0.6°C/W), tighter VF spec (≤1.1 V), and TS-6P packaging optimized for high-density through-hole assembly - making it preferable where board space, thermal performance, and safety certification are jointly critical.

FAQ

What is the maximum junction temperature rating for TS25P01G?

The TS25P01G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable operation in high-ambient environments such as enclosed power supplies or industrial enclosures. Thermal design must ensure that actual junction temperature stays within this limit under worst-case load and ambient conditions using the specified RθJC of 0.6°C/W.

Is TS25P01G UL Recognized, and what is its file number?

Yes, TS25P01G is UL Recognized under File # E-326243. This certification applies to the device's construction, flammability rating (UL 94V-0 molding compound), and terminal plating - supporting end-equipment safety approvals for commercial and industrial power supplies without requiring additional component-level testing.

Does TS25P01G meet AEC-Q101 qualification?

The base TS25P01G is not AEC-Q101 qualified; however, the variant TS25P01GH (with "H" suffix) is explicitly listed as AEC-Q101 qualified in the ordering information. For automotive applications requiring stress-tested reliability, TS25P01GH must be selected instead of TS25P01G.

What is the forward voltage specification for TS25P01G at full rated current?

At IF = 25.0 A and TJ = 25°C, the TS25P01G has a maximum forward voltage (VF) of 1.1 V per diode. This value is measured under pulse conditions (PW = 0.3 ms) and represents the upper bound of conduction loss - critical for calculating efficiency and thermal rise in high-current rectifier designs.

How is polarity marked on the TS25P01G package?

Polarity on the TS25P01G is marked on the top surface of the TS-6P case: the "+" and "–" symbols are laser-etched adjacent to their respective output terminals, and AC input pins are labeled "~" or implied by physical position per standard bridge orientation. The marking diagram in the datasheet confirms AC1/AC2 symmetry and unambiguous +/– identification.
