Taiwan Semiconductor Corporation TSSA5U60H

Overview

TSSA5U60H from Taiwan Semiconductor is a 60 V, 5 A trench Schottky surface-mount rectifier in DO-214AC (SMA) package, optimized for high-frequency DC/DC converters and LED lighting supplies with low forward voltage (0.53 V typ. @ 5 A, 25°C) and high surge capability (75 A IFSM). It operates up to 150°C junction temperature and is AEC-Q101 qualified for automotive-grade reliability.

For engineers reviewing the TSSA5U60H datasheet, TSSA5U60H pinout, TSSA5U60H application, or TSSA5U60H equivalent, key selection criteria include its 60 V VRRM rating, 0.56 V max VF at 5 A/25°C, thermal resistance (RθJL = 28 °C/W), DO-214AC mechanical compatibility, and AEC-Q101 qualification status for harsh-environment power conversion.

Technical Context

This device is a single-die, unidirectional Schottky barrier rectifier using trench MOS structure to reduce forward voltage and leakage while maintaining fast switching and low reverse recovery charge. Its design targets high-efficiency, compact SMPS where conduction loss minimization and thermal management are critical.

The TSSA5U60H delivers 75 A non-repetitive peak forward surge current (8.3 ms half-sine), supports operation from –55°C to +150°C, and features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance - essential for automotive and industrial reflow assembly.

FAQ

What is the maximum junction temperature rating for the TSSA5U60H?

The TSSA5U60H has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision B2307. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves confirm usable current capacity down to –55°C ambient, and thermal resistance values (RθJL = 28 °C/W) support accurate thermal modeling for PCB layout. The TSSA5U60H must be operated within this limit to maintain AEC-Q101 qualification integrity.

Is the TSSA5U60H pin-compatible with the TSSA5U50H?

Yes, the TSSA5U60H is mechanically and electrically pin-compatible with the TSSA5U50H - both use identical DO-214AC (SMA) packaging, anode/cathode pinout, and marking orientation. The only functional difference is VRRM: 60 V for TSSA5U60H versus 50 V for TSSA5U50H. No PCB layout change is required when upgrading, but system-level reverse voltage margin must be validated. Both share identical thermal, surge, and qualification specifications per Taiwan Semiconductor documentation.

What is the typical forward voltage of the TSSA5U60H at 5 A and 125°C?

The typical forward voltage (VF) of the TSSA5U60H is 0.49 V at 5 A and 125°C, per electrical specifications in the Taiwan Semiconductor datasheet (B2307, page 2). This value reflects reduced VF at elevated temperature due to Schottky barrier physics and confirms stable performance across automotive operating ranges. The maximum VF under those conditions is 0.52 V, supporting predictable loss budgeting in thermal-aware designs. This data is measured using pulse test conditions (PW = 0.3 ms).

Does the TSSA5U60H meet AEC-Q101 reliability standards?

Yes, the TSSA5U60H is explicitly AEC-Q101 qualified, as stated in the "FEATURES" section of the Taiwan Semiconductor datasheet (B2307, page 1). Qualification includes stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock - all performed per AEC-Q101-001 Rev D. This certification validates suitability for automotive powertrain, chassis, and body electronics applications where zero-failure reliability is mandatory.

What is the moisture sensitivity level (MSL) of the TSSA5U60H?

The TSSA5U60H has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow. This simplifies manufacturing logistics and eliminates floor-life tracking requirements. The qualification is confirmed in the "FEATURES" list of the Taiwan Semiconductor datasheet (B2307, page 1), and applies to the DO-214AC (SMA) molded package with UL 94V-0 rated compound.
