Taiwan Semiconductor Corporation TS25P04G

Overview

TS25P04G from Taiwan Semiconductor is a 25A, 400V repetitive peak reverse voltage (V_RRM) quad-configuration standard bridge rectifier in TS-6P package, featuring glass-passivated junctions, <0.1μA typical reverse leakage at 25°C, and 350A peak surge current capability - used in industrial SMPS front-end AC/DC conversion stages.

For engineers reviewing the TS25P04G datasheet, TS25P04G pinout, TS25P04G application, or TS25P04G equivalent, key selection factors include V_RRM = 400V, I_F = 25A, R_θJC = 0.6°C/W, AEC-Q101 qualification availability (TS25P04GH), and TS-6P mechanical compatibility with high-density PCB layouts.

Technical Context

The TS25P04G integrates four silicon diodes in a single-phase full-wave bridge configuration, optimized for high-efficiency AC/DC rectification in continuous conduction mode. Its glass-passivated junction ensures stable reverse blocking up to 400V and low IR drift across -55°C to +150°C junction temperature range.

Thermally, it delivers 0.6°C/W junction-to-case resistance, enabling reliable operation at full 25A average forward current with appropriate heatsinking. The device supports 8.3ms half-sine surge events up to 350A without fusing, validated by I²t = 508.37 A²s rating.

FAQ

What is the maximum junction temperature rating for TS25P04G?

The TS25P04G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments when paired with appropriate heatsinking. Derating curves in the datasheet confirm usable current capacity down to 0A at 150°C case temperature. Thermal design must maintain T_J ≤ 150°C under worst-case load and ambient conditions to ensure reliability of the TS25P04G.

Does TS25P04G have AEC-Q101 qualification?

The standard TS25P04G is not AEC-Q101 qualified, but the pin-compatible variant TS25P04GH is explicitly qualified per AEC-Q101 Rev D for automotive applications. The "H" suffix denotes qualification, including stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress test. For automotive designs requiring AEC-Q101, TS25P04GH - not TS25P04G - must be specified and sourced.

What is the forward voltage drop of TS25P04G at full rated current?

At I_F = 25A and T_J = 25°C, the TS25P04G exhibits a maximum forward voltage drop (V_F) of 1.1V per diode, measured under pulse conditions (PW = 0.3ms). This value increases with junction temperature - at 125°C, V_F remains ≤1.15V. Conduction loss calculation for the full bridge uses two diodes in series per half-cycle, so total V_F ≈ 2.2V at 25A.

How does the TS-6P package of TS25P04G compare thermally to TO-220AC alternatives?

The TS25P04G's TS-6P package achieves R_θJC = 0.6°C/W, significantly lower than typical TO-220AC bridge rectifiers (e.g., 1.0–1.2°C/W). This 40% improvement enables higher power density and reduced heatsink size. The TS-6P's metal baseplate provides direct thermal interface to heatsinks, whereas TO-220AC relies on lead-frame conduction - making TS25P04G more effective in thermally constrained layouts.

Is TS25P04G suitable for use in lighting applications with high ambient temperatures?

Yes - the TS25P04G is widely deployed in LED driver designs operating up to +85°C ambient, supported by its -55°C to +150°C storage and operating junction range. Its low reverse leakage (<0.1μA at 25°C, <500μA at 125°C) prevents excessive standby loss, and the UL 94V-0 molding compound withstands prolonged thermal exposure. Real-world lighting applications validate TS25P04G reliability at 70°C case temperature under full 25A load.
