Taiwan Semiconductor Corporation TS20P01G D2G

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, and UL recognition (E-326243). It is designed for high-reliability AC/DC conversion in compact PCB-mounted power supplies.

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 through-hole mounting.

Technical Context

The TS20P01G integrates four diodes in a single-phase bridge configuration with common-cathode/common-anode topology, enabling full-wave rectification without external interconnection. Its glass-passivated chip junction ensures stable reverse characteristics across temperature and long-term reliability under repeated surge stress.

Thermal performance is defined by a low junction-to-case thermal resistance of 0.8 °C/W, supporting continuous 20A operation up to 150°C junction temperature when properly heatsinked. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for molded compound.

Key Specifications

Pinout & Package

TS-6P is a 6-terminal through-hole package with integrated quad bridge topology. Terminals are arranged as AC1, AC2, +DC (common cathode), –DC (common anode), and two internal tie points (typically unused externally but structurally part of the bridge die assembly).

FAQ

What is the maximum junction temperature rating for TS20P01G?

The TS20P01G has a maximum junction temperature (TJ max) of +150 °C, verified per absolute maximum ratings in the official datasheet. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or automotive under-hood auxiliary circuits. Derating curves in Figure 1 confirm 20 A average forward current is sustainable up to 100 °C case temperature when mounted on an appropriate heatsink. The TS20P01G must not exceed this limit to maintain long-term reliability and avoid parametric shift.

Does TS20P01G have AEC-Q101 qualification?

The base TS20P01G is not AEC-Q101 qualified; however, the variant TS20P01GH is explicitly listed in the ordering information as AEC-Q101 qualified. This distinction is marked by the "H" suffix in the part number and confirmed in the datasheet's ordering code table. For automotive applications requiring AEC-Q101 compliance, TS20P01GH-not TS20P01G-must be specified and sourced. Both share identical electrical and thermal specifications except for qualification status and associated test documentation.

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

The TS20P01G exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 20 A and TJ = 25 °C, as specified in the Electrical Specifications table. This value is measured under pulse conditions (PW = 0.3 ms) to avoid self-heating effects. At lower currents (e.g., 10 A), VF drops to ≤1.0 V. These values directly impact conduction losses in rectifier stage design and must be used with thermal resistance data (RθJC = 0.8 °C/W) to model total power dissipation in the TS20P01G.

How does the TS-6P package of TS20P01G differ from standard GBPC packages?

The TS-6P package of TS20P01G is a proprietary 6-pin through-hole outline with tighter dimensional control and optimized thermal path versus legacy GBPC packages. Key differences include lower junction-to-case thermal resistance (0.8 °C/W vs. ≥1.2 °C/W for most GBPC variants), matte tin-plated leads compliant with J-STD-002, and 0.92 N·m maximum mounting torque specification. Unlike GBPC, TS-6P uses internal tie pins (Pins 5–6) that are not electrically functional but reinforce mechanical integrity during wave soldering.

What is the reverse leakage current specification for TS20P01G?

The TS20P01G specifies a maximum reverse current (IR) of 10 μA per diode at TJ = 25 °C and rated VR, with a worst-case value of 500 μA at TJ = 125 °C. These values are measured using a 30 ms pulse per note 2 in the datasheet. Low IR improves no-load efficiency and reduces standby power in energy-sensitive applications like LED drivers and IoT power supplies. The TS20P01G's typical IR is less than 0.1 μA at 25 °C, significantly below the max spec.
