Taiwan Semiconductor Corporation TS20P03G D2G

Overview

TS20P03G from Taiwan Semiconductor is a 20A, 200V 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 250A peak surge current capability - used in AC/DC front-end stages of industrial SMPS and LED drivers.

For engineers reviewing the TS20P03G datasheet, TS20P03G pinout, TS20P03G application, or TS20P03G equivalent, key selection criteria include V_RRM = 200V, I_F = 20A continuous, thermal resistance R_θJC = 0.8°C/W, AEC-Q101 qualification availability (TS20P03GH), and TS-6P mechanical compatibility with PCB-mount high-current rectification.

Technical Context

The TS20P03G integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology, optimized for line-frequency and high-frequency switching rectification. Its glass-passivated junction ensures stable reverse characteristics across -55°C to +150°C junction temperature range.

Designed for surface-mount-compatible through-hole installation, the device supports 250A non-repetitive surge (8.3ms half-sine) and delivers ≤1.1V forward voltage at 20A/25°C, enabling efficient thermal management in compact power supplies where case-to-heatsink conduction is critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the TS20P03G?

The TS20P03G has a V_RRM of 200 V, confirmed in the Absolute Maximum Ratings table. This value defines the highest sinusoidal reverse voltage the device can block repeatedly without breakdown - corresponding to ~140V_RMS AC input. It is distinct from the TS20P04G (400V) and TS20P02G (100V) variants in the same family.

Does the TS20P03G have AEC-Q101 qualification?

The TS20P03G itself is not AEC-Q101 qualified; however, the TS20P03GH variant - identical electrically and mechanically but with enhanced process controls and test screening - is AEC-Q101 qualified. The "H" suffix denotes this automotive-grade version, documented in the Ordering Information section.

What is the forward voltage drop (V_F) of the TS20P03G at rated current?

At I_F = 20 A and T_J = 25°C, the TS20P03G exhibits a maximum forward voltage of 1.1 V per diode, as specified in the Electrical Specifications table. This results in ~2.2 V total drop across the bridge under full-load conduction, directly impacting conduction loss and thermal design.

Can the TS20P03G be mounted directly to a heatsink?

Yes - the TS-6P package features an electrically isolated metal baseplate designed for direct thermal interface to heatsinks. With R_θJC = 0.8°C/W, mounting torque must not exceed 0.92 N·m to avoid package damage, and thermal interface material is recommended for optimal conduction.

What is the reverse leakage current (I_R) of the TS20P03G at elevated temperature?

At T_J = 125°C and rated V_R, the TS20P03G specifies a maximum reverse leakage current of 500 µA per diode (pulse test, 30 ms). This is significantly higher than the <0.1 µA typical value at 25°C, reflecting expected silicon behavior and informing standby-loss calculations in high-ambient designs.
