Taiwan Semiconductor Corporation TS25P05G-K

Overview

TS25P05G-K from Taiwan Semiconductor is a 25A, 600V standard quad bridge rectifier in TS-6P package, featuring glass-passivated junctions, <10µA reverse current at 25°C, and 350A surge capability - deployed in AC/DC front-end stages of industrial SMPS.

For engineers reviewing the TS25P05G-K datasheet, TS25P05G-K pinout, TS25P05G-K application, or TS25P05G-K equivalent, key selection criteria include V_RRM = 600V, I_F = 25A, R_θJC = 1.3°C/W, and TS-6P mechanical compatibility with high-density PCB layouts.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration, optimized for line-frequency and high-efficiency switching-mode power conversion. Its glass-passivated junction ensures stable leakage performance (I_R ≤ 10 µA @ 25°C) and robustness against humidity and contamination.

The TS-6P package provides low thermal resistance (R_θJC = 1.3°C/W) and matte tin-plated leads compliant with J-STD-002 solderability. Polarity is marked on the case, and mounting torque must not exceed 0.92 N·m to avoid internal bond damage.

FAQ

What is the maximum junction temperature rating for TS25P05G-K?

The TS25P05G-K has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This rating applies under continuous forward conduction at I_F = 25A with proper thermal management. Operation beyond this limit risks irreversible degradation of the glass-passivated junction. Derating curves in the datasheet specify allowable I_F reduction above 100°C case temperature. The TS25P05G-K must be mounted with torque ≤0.92 N·m to preserve internal thermal paths.

Is TS25P05G-K pin-compatible with other TS-6P bridge rectifiers?

Yes, TS25P05G-K uses the standardized TS-6P footprint and pinout (AC1, AC2, +, –), matching industry-standard quad bridge layouts. It shares identical lead pitch, body dimensions, and polarity marking orientation with TS25P06G-K and TS25P07G-K. However, voltage-rated variants differ in V_RRM only - all share identical thermal, electrical, and mechanical specs except reverse voltage rating. No PCB changes are needed when substituting within the TS25P-xG-K family.

Does TS25P05G-K meet UL safety certification requirements?

Yes, TS25P05G-K is UL Recognized under File #E-326243, confirming compliance with UL 60747-4 for semiconductor devices. This certification covers construction, flammability (UL 94V-0 molding compound), and electrical insulation integrity. It supports end-equipment safety approvals for Class I and II power supplies in North America. The TS25P05G-K marking includes "G" for green compound and date code per TSC's TS-6P marking diagram.

What is the typical forward voltage drop of TS25P05G-K at rated current?

At I_F = 12.5A per diode and T_J = 25°C, the TS25P05G-K exhibits a typical forward voltage (V_F) of ≤1.1V - measured under pulse test (PW = 0.3ms). At elevated junction temperature (125°C), V_F drops to ≤1.0V due to negative temperature coefficient of silicon diodes. This low V_F contributes to reduced conduction losses in high-efficiency SMPS designs using the TS25P05G-K.

How does the thermal resistance of TS25P05G-K impact heatsink selection?

With R_θJC = 1.3°C/W, the TS25P05G-K transfers heat efficiently from junction to case, enabling compact thermal solutions. For example, at 25A continuous load and 1.1V V_F, power dissipation is ~27.5W; combined with R_θJA ≈ 25°C/W (board-mounted, no heatsink), junction rise would exceed 150°C. A heatsink adding ≤2.0°C/W R_θSA keeps T_J within spec. The TS25P05G-K's low R_θJC makes it suitable for chassis-mount conduction cooling in space-constrained adapters.
