Taiwan Semiconductor Corporation TS35P05GH

Overview

TS35P05GH from Taiwan Semiconductor is a 35A, 600V AEC-Q101-qualified standard quad bridge rectifier in TS-6P package, featuring glass-passivated junctions, <0.1μA typical reverse leakage at 25°C, 350A peak surge capability, and UL Recognized File #E-326243. It is used in automotive-grade SMPS and lighting power supplies requiring high reliability under thermal stress.

For engineers reviewing the TS35P05GH datasheet, TS35P05GH pinout, TS35P05GH application, or TS35P05GH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (35 A), junction-to-case thermal resistance (0.6 °C/W), AEC-Q101 qualification status, and TS-6P mechanical compatibility with PCB-mounting torque limits (0.92 N·m max).

Technical Context

The TS35P05GH integrates four silicon diodes in a single-phase full-wave bridge configuration within a molded TS-6P case, enabling compact AC-to-DC conversion without external interconnects. Its glass-passivated junction ensures stable reverse characteristics across -55°C to +150°C operating range and supports high-reliability automotive applications.

Thermal performance is defined by R_θJC = 0.6 °C/W, allowing efficient heat transfer to heatsinks or PCB copper planes. The device sustains 350 A non-repetitive surge current (8.3 ms half-sine) and exhibits ≤1.1 V forward voltage per diode at 17.5 A and 25°C junction temperature.

FAQ

What does the "H" suffix in TS35P05GH signify?

The "H" suffix in TS35P05GH explicitly denotes AEC-Q101 qualification, confirming that the device has passed rigorous automotive-grade stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This distinguishes TS35P05GH from the non-automotive TS35P05G variant and validates its use in automotive power modules, onboard chargers, and ADAS subsystems where reliability is mission-critical. TS35P05GH retains identical electrical ratings and TS-6P packaging as TS35P05G.

Is TS35P05GH pin-compatible with other TS-6P bridge rectifiers?

Yes, TS35P05GH uses the standardized TS-6P footprint and terminal layout defined by Taiwan Semiconductor, matching mechanical and soldering dimensions of TS35P06GH and TS35P07GH. All share identical AC1/AC2/+/- pin assignments and 0.92 N·m maximum mounting torque. However, voltage ratings differ (600 V vs. 800 V vs. 1000 V), so substitution requires verification of reverse voltage margin in the target circuit. TS35P05GH is not pin-compatible with GBPC or KBPC packages.

What is the maximum allowable case temperature for continuous operation of TS35P05GH?

The TS35P05GH is rated for continuous operation with case temperature up to +150°C, aligned with its maximum junction temperature (TJ max = +150°C) and junction-to-case thermal resistance of 0.6 °C/W. To maintain this limit, the device must be mounted to a heatsink or copper plane capable of dissipating ≥25 W at ambient conditions. Derating curves in the datasheet specify reduced IF above 100°C case temperature; operation beyond 150°C case risks irreversible parametric shift and premature failure.

Does TS35P05GH require external snubbers or clamping circuits in typical SMPS designs?

TS35P05GH does not require external snubbers in standard flyback or forward converter topologies operating below 100 kHz, due to its low junction capacitance (<100 pF at 1 MHz) and robust 600 V VRRM margin over typical reflected voltages. However, in high-frequency resonant converters or systems subject to lightning-induced surges, a parallel RC snubber may be added to suppress ringing and reduce EMI. Designers should verify dv/dt stress using oscilloscope measurements at the AC terminals before finalizing snubber decisions for TS35P05GH.

How does the glass passivation in TS35P05GH improve long-term reliability?

Glass passivation in TS35P05GH forms a hermetic, chemically inert barrier over the silicon junction, preventing oxidation, metal ion migration, and moisture ingress that cause gradual IR increase and eventual thermal runaway. This structure extends operational lifetime in humid or chemically aggressive environments (e.g., outdoor LED fixtures, under-hood automotive locations) and maintains reverse leakage below 500 µA even after 10,000 hours at 125°C junction temperature-directly supporting TS35P05GH's AEC-Q101 qualification and UL recognition.
