Product details
Overview
TSU2M60H from Taiwan Semiconductor is a 2 A, 60 V Trench Schottky surface-mount rectifier in Micro SMA package, featuring AEC-Q101 qualification, low forward voltage (0.72 V @ 2 A, 25°C), and 175°C max junction temperature-designed for high-efficiency automotive DC/DC converters.
For engineers reviewing the TSU2M60H datasheet, TSU2M60H pinout, TSU2M60H application, or TSU2M60H equivalent, key selection criteria include its 30 A surge rating, 19°C/W junction-to-lead thermal resistance, J-STD-020 Level 1 moisture sensitivity, and RoHS/halogen-free compliance for automotive-grade reliability.
Technical Context
The TSU2M60H employs patented Trench Schottky technology to achieve low conduction loss and fast switching with no reverse recovery charge-critical for high-frequency SMPS and on-board DC/DC converters. Its single-die configuration and cathode-band polarity marking support automated placement and unambiguous orientation on PCBs.
Thermal performance is specified with 19°C/W RθJL and 68°C/W RθJA (on 5 mm × 5 mm Cu pad), enabling compact thermal design in space-constrained automotive modules. Reverse leakage remains ≤5 mA at 125°C, supporting stable operation across extended temperature ranges.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY60HM3/52 | Same 2 A / 60 V rating, but TO-277A package (larger footprint, higher RθJA = 85°C/W) | Less suitable for ultra-compact automotive modules due to 30% larger board area | Prefer TSU2M60H where Micro SMA footprint and thermal performance are critical |
| ON Semiconductor SB260 | 2 A / 60 V, DO-214AA package, VF = 0.85 V @ 2 A - 18% higher conduction loss | Higher power dissipation requires derating above 85°C ambient | TSU2M60H preferred for high-temp automotive or high-efficiency lighting designs |
Compared with VS-2EY60HM3/52 and SB260, the TSU2M60H delivers superior thermal efficiency (19°C/W RθJL), AEC-Q101 qualification, and halogen-free compliance-making it the optimal choice for space- and reliability-constrained automotive and industrial power stages.

FAQ
What is the maximum junction temperature rating for the TSU2M60H?
The TSU2M60H has a maximum junction temperature (TJ) of +175°C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive applications and enclosed industrial power supplies where ambient temperatures exceed 105°C. The TSU2M60H maintains stable electrical parameters-including low reverse leakage-up to this limit when mounted per recommended PCB thermal pads.
Is the TSU2M60H pin-compatible with standard SMA packages?
No-the TSU2M60H uses the Micro SMA package, which is smaller than standard SMA (DO-214AC). Its dimensions and pad layout differ significantly; the recommended land pattern is provided in TSC's Package Outline Dimensions document. Using a standard SMA footprint would cause solder joint reliability issues and thermal performance degradation for the TSU2M60H.
Does the TSU2M60H have a specified reverse recovery time?
No-the TSU2M60H is a Schottky rectifier using Trench technology and exhibits no minority-carrier storage; therefore, it has effectively zero reverse recovery time (trr ≈ 0 ns). This eliminates switching losses and associated EMI in high-frequency SMPS designs, a key advantage confirmed in the device's Electrical Specifications and Characteristics Curves.
What is the marking code printed on the TSU2M60H device body?
The TSU2M60H is marked with the code "Z4" on its top surface, as specified in the Absolute Maximum Ratings table. This 2-character marking identifies the device variant and is used for traceability and visual inspection during assembly. No date code or additional symbols are part of the standard TSU2M60H marking per Version B2208 documentation.
How does the TSU2M60H's thermal resistance compare to conventional SMA Schottky diodes?
The TSU2M60H achieves RθJL = 19°C/W-significantly lower than typical SMA-packaged Schottkys (often >35°C/W)-due to optimized leadframe design and die attach. This enables higher current capability without heatsinks in constrained layouts. Measured on a 5 mm × 5 mm Cu pad, its RθJA = 68°C/W also outperforms legacy SMA equivalents by ~15%, directly improving power density in the TSU2M60H.
