Product details
Overview
TUAU8JH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified surface-mount rectifier with 600 V repetitive peak reverse voltage (VRRM), 8 A average forward current (IF), and 140 A surge capability (IFSM). It features fast recovery time (≤50 ns), wettable flank leads for automated optical inspection, and operates up to 150 °C junction temperature - deployed in automotive lighting and DC-DC converters.
For engineers reviewing the TUAU8JH datasheet, TUAU8JH pinout, TUAU8JH application, or TUAU8JH equivalent, key selection criteria include its 600 V VRRM, 1.24 V forward voltage at 8 A/25 °C, 50 ns reverse recovery time, TO-277A (SMPC4.6U) package with cathode-band polarity marking, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The TUAU8JH is a single-die, glass-passivated, ultra-fast recovery rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time (trr) and low junction capacitance (80 pF at 4 V) minimize switching losses in snubber and freewheeling circuits.
Thermally, it delivers RθJL = 5.5 °C/W and RθJA = 48 °C/W on a 16 mm × 16 mm Cu pad PCB, supporting continuous 8 A operation under controlled thermal conditions. Junction temperature range is −55 °C to +150 °C, with moisture sensitivity level 1 per J-STD-020.
Key Specifications

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the TUAU8JH?
The TUAU8JH has a VRRM of 600 V, confirmed in the Absolute Maximum Ratings table. This rating defines the highest reverse voltage the device can block repeatedly without avalanche breakdown. It is validated across temperature and used to select appropriate voltage margins in 48 V and 300 V nominal systems. The TUAU8JH maintains this rating while operating within its −55 °C to +150 °C junction temperature range.
Is the TUAU8JH qualified for automotive applications?
Yes, the TUAU8JH is AEC-Q101 qualified, as explicitly stated in the FEATURES section. This qualification covers stress tests including high-temperature gate bias (HTGB), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). The TUAU8JH meets these requirements in its TO-277A package with glass passivation and halogen-free construction.
What is the forward voltage (VF) of the TUAU8JH at 8 A and 25 °C?
The TUAU8JH exhibits a typical forward voltage of 1.24 V at 8 A and 25 °C, with a maximum of 1.7 V under those conditions. This value is specified in the Electrical Specifications table and directly impacts conduction loss and thermal design. At elevated temperatures (e.g., 125 °C), VF drops to 1.05 V max, improving efficiency in thermally constrained layouts.
Does the TUAU8JH have wettable flank leads?
Yes, the TUAU8JH features wettable flank leads, as listed in the FEATURES section. These leads extend solderable surfaces down the side walls of the TO-277A package, enabling reliable automated optical inspection (AOI) of solder joint quality in high-volume SMT assembly. This feature is critical for automotive manufacturing process control and zero-defect initiatives.
What is the reverse recovery time (trr) of the TUAU8JH?
The TUAU8JH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultra-fast recovery enables high-frequency switching (>100 kHz) with minimal switching loss and EMI. The trr remains stable across its rated temperature range and supports use in snubber and freewheeling roles where rapid turn-off is essential.
