Taiwan Semiconductor Corporation TSSA3U60H

Overview

TSSA3U60H from Taiwan Semiconductor is a 3A, 60V trench Schottky surface-mount rectifier in DO-214AC (SMA) package, featuring low forward voltage (0.54 V max at 3A/25°C), high surge capability (60 A IFSM), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in compact high-frequency SMPS for LED drivers and AC/DC adapters.

For engineers reviewing the TSSA3U60H datasheet, TSSA3U60H pinout, TSSA3U60H application, or TSSA3U60H equivalent, key selection criteria include VF vs. temperature performance, TJ max rating (150°C), reverse leakage at 125°C (30 mA), junction-to-lead thermal resistance (27°C/W), and compliance with JESD201 Class 2 whisker testing.

Technical Context

The TSSA3U60H employs a single-die trench Schottky barrier structure optimized for minimal conduction loss and fast switching. Its 25 ns reverse recovery time and 241 pF junction capacitance support operation in >100 kHz switch-mode topologies without significant switching loss penalties.

Thermal design is enabled by its DO-214AC package with 27°C/W junction-to-lead resistance when mounted on a 5 mm × 5 mm copper pad. The device operates across -55°C to +150°C junction temperature range and meets moisture sensitivity level 1 per J-STD-020.

FAQ

What is the maximum junction temperature rating for TSSA3U60H?

The TSSA3U60H has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in sealed enclosures or under-hood automotive environments where ambient temperatures exceed 100°C. Derating curves confirm usable current capacity down to 1.5 A at 125°C case temperature. Thermal design must respect the 27°C/W junction-to-lead resistance when using recommended 5 mm × 5 mm Cu pads.

Is TSSA3U60H suitable for automotive applications?

Yes, the TSSA3U60H is AEC-Q101 qualified and explicitly designed for automotive applications. Its qualification covers temperature cycling, mechanical shock, humidity bias, and highly accelerated stress test (HAST) per AEC-Q101 Rev D. The device is used in LED headlamp drivers, body control modules, and infotainment power supplies where -55°C to +150°C operation and vibration resilience are required. TSSA3U60H meets JESD201 Class 2 whisker resistance and moisture sensitivity level 1.

What is the forward voltage of TSSA3U60H at 3 A and 125°C?

At 3 A forward current and 125°C junction temperature, the TSSA3U60H exhibits a typical forward voltage (VF) of 0.43 V, with a maximum of 0.50 V per electrical specifications table. This low VF at elevated temperature directly improves system efficiency in thermally stressed applications such as enclosed LED drivers or automotive cabin modules. Pulse testing conditions (PW = 0.3 ms) ensure measurement accuracy under realistic switching conditions.

Does TSSA3U60H have a defined reverse recovery time?

Yes, the TSSA3U60H specifies a reverse recovery time (trr) of up to 25 ns under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. As a Schottky rectifier, it achieves this fast switching via majority-carrier conduction-eliminating minority-carrier storage delay. This enables clean commutation in high-frequency flyback and resonant converters, reducing EMI and voltage spikes compared to PN diodes. Measured at 1 MHz with VR = 4.0 V.

What packaging and reel quantity is offered for TSSA3U60H?

The TSSA3U60H is supplied in DO-214AC (SMA) package on 7,500-unit tape-and-reel format, per ordering information table. The reel complies with EIA-481-D standards and includes moisture barrier bag packaging with desiccant and humidity indicator card. Lead finish is matte tin per J-STD-002, supporting both leaded and lead-free reflow profiles. Marking code "3U60" is laser-etched on the cathode-banded surface.
