Taiwan Semiconductor Corporation TS15P04G

Overview

TS15P04G from Taiwan Semiconductor is a 15A, 400V repetitive peak reverse voltage (V_RRM) quad-configuration standard bridge rectifier with glass-passivated junctions, 240A peak surge capability (I_FSM), 0.8°C/W junction-to-case thermal resistance, and UL Recognized File #E-326243 - used in AC/DC front-end stages of industrial SMPS.

For engineers reviewing the TS15P04G datasheet, TS15P04G pinout, TS15P04G application, or TS15P04G equivalent, key selection criteria include V_RRM = 400V, I_F = 15A, TS-6P package mounting torque limit (0.92 N·m), and AEC-Q101 qualification availability (TS15P04GH variant).

Technical Context

The TS15P04G integrates four silicon diodes in a single-phase full-wave bridge configuration within a TS-6P molded package, enabling direct AC input rectification without external interconnects. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.

Thermal performance is defined by R_θJC = 0.8°C/W, supporting continuous 15A conduction at case temperatures up to 100°C when properly heatsinked. The device operates across -55°C to +150°C junction range and meets JESD201 Class 2 whisker resistance.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for TS15P04G?

The TS15P04G has a maximum junction temperature (T_J) of +150°C, with an operational range from -55°C to +150°C. This rating allows reliable operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. Thermal design must ensure that actual junction temperature stays within this limit using the specified R_θJC = 0.8°C/W and appropriate heatsinking. TS15P04G maintains stable electrical parameters across this full range.

Does TS15P04G have AEC-Q101 qualification?

The base TS15P04G is not AEC-Q101 qualified; however, the TS15P04GH variant is explicitly qualified per AEC-Q101. Both share identical electrical and thermal specifications, with the 'H' suffix indicating automotive-grade stress testing including HTGB, HTRB, and temperature cycling. For automotive body electronics or ADAS auxiliary power modules, TS15P04GH is the designated qualified version.

What is the forward voltage drop of TS15P04G at full rated current?

At I_F = 15 A and T_J = 25°C, the TS15P04G exhibits a maximum forward voltage drop of 1.1 V per diode - meaning the total bridge drop is ~2.2 V under worst-case conduction. This value is measured under pulsed conditions (PW = 0.3 ms) and remains stable up to 125°C. Lower V_F directly reduces conduction losses and improves system efficiency compared to alternatives like GBPC1504.

How does the TS-6P package of TS15P04G differ from standard GBPC packages?

The TS-6P package used by TS15P04G is a surface-mount, 6-terminal molded outline with a thermally enhanced metal slug, whereas GBPC packages are through-hole with larger creepage distances and higher R_θJC. TS-6P enables automated SMT assembly, occupies less PCB area, and achieves lower thermal resistance (0.8°C/W vs. ≥1.2°C/W). Polarity marking and lead finish (matte tin) also comply with J-STD-002, unlike many legacy GBPC variants.

What is the reverse leakage current specification for TS15P04G at elevated temperature?

At T_J = 125°C and rated reverse voltage, TS15P04G specifies a maximum reverse leakage current (I_R) of 500 µA per diode - significantly lower than industry-standard thresholds for 15A bridges. This low leakage preserves efficiency in standby modes and prevents unintended biasing in high-impedance feedback networks. The value is verified under 30 ms pulse test conditions and reflects stable glass-passivated junction behavior.
