Taiwan Semiconductor Corporation TS20P01GHD2G

Overview

TS20P01GHD2G from Taiwan Semiconductor is a 20A, 50V AEC-Q101-qualified standard bridge rectifier in TS-6P package with quad configuration, glass passivated junction, <0.1μA typical reverse leakage at 25°C, and 250A peak surge current capability-used in automotive-grade SMPS and lighting adapters.

For engineers reviewing the TS20P01GHD2G datasheet, TS20P01GHD2G pinout, TS20P01GHD2G application, or TS20P01GHD2G equivalent, key selection factors include repetitive peak reverse voltage (50 V), forward current rating (20 A), thermal resistance (0.8 °C/W), AEC-Q101 qualification status, and TS-6P mechanical compatibility for high-reliability board-level power conversion.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling AC-to-DC conversion without external interconnects. Its glass passivated junction ensures stable reverse characteristics across temperature, while the TS-6P case supports high thermal dissipation via case mounting.

The TS20P01GHD2G operates with a maximum junction temperature of 150°C and exhibits 1.0 V typical forward voltage per diode at 10 A/25°C, rising to 1.1 V at 20 A/25°C-critical for conduction loss estimation in compact power supplies.

FAQ

What does the 'H' suffix in TS20P01GHD2G indicate?

The 'H' in TS20P01GHD2G denotes AEC-Q101 qualification-verified by Taiwan Semiconductor for automotive-grade reliability under temperature cycling, mechanical shock, and humidity testing. This distinguishes TS20P01GHD2G from standard TS20P01G variants and confirms its suitability for vehicle-mounted power systems where failure modes must be rigorously controlled. TS20P01GHD2G maintains identical electrical specs and TS-6P packaging as the base part.

Is TS20P01GHD2G pin-compatible with other TS-6P bridge rectifiers?

Yes-TS20P01GHD2G uses the standardized TS-6P footprint with AC1, AC2, +, and – terminals in fixed positions per the official Taiwan Semiconductor package drawing. It shares mechanical and soldering compatibility with all TS20PxG and TS20PxGH variants, enabling voltage-scaling design reuse (e.g., swapping TS20P01GHD2G for TS20P04GHD2G) without PCB revision. Mounting torque must not exceed 0.92 N·m.

What is the maximum allowable case temperature for TS20P01GHD2G during operation?

The maximum case temperature for TS20P01GHD2G is derived from its 150°C maximum junction temperature and 0.8 °C/W junction-to-case thermal resistance. Under 20 A DC load with 1.1 V forward drop, power dissipation is ~22 W; thus, case temperature must remain ≤132°C to maintain safe junction margin. Actual limit depends on heatsinking-designers should verify using measured R_θCA and ambient conditions.

Does TS20P01GHD2G meet creepage and clearance requirements for reinforced insulation?

TS20P01GHD2G's TS-6P package provides ≥5.0 mm creepage and ≥4.0 mm clearance between AC1/AC2 and +/– terminals per IEC 60664-1, validated by UL Recognition File E-326243. These distances satisfy reinforced insulation requirements for 230 VAC input systems up to Pollution Degree 2. Layout must preserve minimum spacing on PCB; conformal coating may be added for Pollution Degree 3 environments.

How does the glass passivation in TS20P01GHD2G improve long-term reliability?

Glass passivation in TS20P01GHD2G forms a hermetic barrier over the silicon junction, preventing moisture ingress and ion migration that cause parametric drift or premature reverse leakage increase. This extends operational life in humid or thermally cycled environments-especially critical for automotive and outdoor lighting applications where field failures must be minimized over 10+ years. Data shows <10% IR shift after 1000 hrs at 85°C/85% RH.
