Taiwan Semiconductor Corporation TS25P04G C2G

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 and lighting ballasts requiring high-reliability AC/DC conversion.

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

Technical Context

The TS25P04G integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced moisture and contamination resistance. Its 0.6°C/W junction-to-case thermal resistance supports conduction-cooled operation up to 150°C junction temperature under 25A DC forward current.

Electrical behavior is defined by two critical operating points: forward voltage ≤1.0V at 12.5A/25°C and ≤1.1V at 25A/25°C; reverse current ≤10μA at rated 400V V_RRM and 25°C, rising to ≤500μA at 125°C - confirming stable blocking performance across automotive-grade temperature ranges.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in power rectifiers, TVS diodes, MOSFETs, and IGBTs since 1979.

The TS25P series was developed specifically for high-current, high-reliability AC/DC front-end rectification in industrial, lighting, and automotive applications - emphasizing thermal robustness, low leakage, and mechanical ruggedness in TS-6P packaging.

FAQ

What is the maximum junction temperature rating for TS25P04G?

The TS25P04G has a maximum junction temperature (T_J) 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 define safe I_F limits above 75°C case temperature. The TS25P04G maintains specified electrical parameters within this range, provided thermal design respects R_θJC = 0.6°C/W and system-level R_θCA.

Does TS25P04G have AEC-Q101 qualification?

The TS25P04G itself is not AEC-Q101 qualified; however, the pin-compatible TS25P04GH variant is explicitly qualified per AEC-Q101 Rev D. Both share identical electrical specs and TS-6P packaging. For automotive under-hood use, TS25P04GH must be selected - the "H" suffix denotes qualification. No layout change is needed when upgrading from TS25P04G to TS25P04GH.

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 - meaning total bridge drop is ~2.2V under worst-case conduction. This value is measured under pulse conditions (PW = 0.3ms) and defines conduction loss for thermal modeling. At elevated junction temperatures, V_F decreases slightly due to negative temperature coefficient.

How does TS25P04G compare to TS25P03G in terms of voltage rating and application suitability?

The TS25P04G has a 400V V_RRM, while TS25P03G is rated at 200V. Both share identical I_F = 25A, I_FSM = 350A, and TS-6P packaging. TS25P04G is suited for universal-input (90–264VAC) or 230VAC-only systems with higher line transients; TS25P03G fits 120VAC-only or low-transient designs. Selecting TS25P04G provides additional margin against voltage spikes in industrial mains environments.

What is the marking code and date code format on TS25P04G devices?

TS25P04G devices are marked with "TS25P04G" followed by "G" (green compound), a 2-digit year + 2-digit week (YWW) date code, and a factory code (e.g., "F"). Marking appears on the top surface of the TS-6P package per the official outline drawing. The "G" suffix confirms halogen-free molding compound compliant with IEC 61249-2-21 - a requirement traceable via the device marking.
