Taiwan Semiconductor Corporation TS20P01G C2G

Overview

TS20P01G from Taiwan Semiconductor is a 20A, 50V standard quad bridge rectifier in TS-6P package, featuring glass-passivated junctions, <0.1μA typical reverse leakage at 25°C, 250A peak surge current capability, and UL recognition (E-326243), designed for high-reliability AC/DC conversion in compact power adapters.

For engineers reviewing the TS20P01G datasheet, TS20P01G pinout, TS20P01G application, or TS20P01G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward current rating (20 A), thermal resistance (0.8 °C/W), AEC-Q101 qualification availability, and TS-6P mechanical compatibility with PCB-mounting requirements.

Technical Context

The TS20P01G integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology. Its glass-passivated junction ensures stable reverse characteristics across temperature, while the TS-6P thermally optimized package enables efficient heat transfer to heatsinks or PCB copper planes.

Rated for 150°C maximum junction temperature and compliant with JESD201 Class 2 whisker resistance, the device supports high-density board layouts in switching mode power supplies where low forward voltage (≤1.1 V @ 20 A) and minimal reverse leakage (<10 μA @ 25°C) directly impact efficiency and standby power performance.

FAQ

What is the maximum junction temperature rating for TS20P01G?

The TS20P01G has a maximum junction temperature (T_J) rating of +150°C, allowing reliable operation in enclosed or high-ambient-temperature environments such as LED drivers and industrial power modules. This rating is validated under specified thermal conditions and must be maintained via appropriate heatsinking or PCB copper area to prevent exceeding TJ MAX during 20 A continuous conduction. The TS20P01G datasheet specifies derating curves confirming safe operation down to –55°C storage temperature.

Is TS20P01G pin-compatible with other TS-6P bridge rectifiers like TS20P02G or TS20P03G?

Yes, TS20P01G shares identical TS-6P package dimensions, pinout, and terminal configuration with all members of the TS20P01G–TS20P07G family, including TS20P02G and TS20P03G. The only difference is the rated repetitive peak reverse voltage (V_RRM): 50 V for TS20P01G, 100 V for TS20P02G, and 200 V for TS20P03G. Mechanical and electrical interface compatibility enables direct substitution in layouts where voltage margin permits.

Does TS20P01G meet automotive reliability standards?

TS20P01G itself is not AEC-Q101 qualified; however, the TS20P01GH variant (same electrical specs, "H" suffix) is AEC-Q101 qualified and UL recognized. The base TS20P01G uses the same glass-passivated die and TS-6P construction but lacks the extended test program required for automotive qualification. For automotive aftermarket or under-hood applications, TS20P01GH is the designated qualified version of TS20P01G.

What is the typical forward voltage drop of TS20P01G at rated current?

The TS20P01G exhibits a typical forward voltage drop of 1.0 V per diode at 10 A and 25°C junction temperature, rising to a maximum of 1.1 V per diode at 20 A and 25°C (pulse test, PW = 0.3 ms). This low VF contributes to reduced conduction losses in high-current rectification stages, especially critical in energy-efficient adapters and LED drivers where thermal management is constrained.

How does the thermal resistance of TS20P01G compare to industry-standard bridge packages?

TS20P01G achieves a junction-to-case thermal resistance (R_θJC) of 0.8 °C/W, significantly lower than standard GBU (1.5 °C/W) or KBPC (2.0 °C/W) packages. This 47% improvement enables higher power density and relaxed heatsink requirements. The TS-6P package's optimized internal leadframe and mold compound directly contribute to this performance, making TS20P01G suitable for thermally aggressive applications where conventional bridges would require derating or active cooling.
