Product details
Overview
TSSE3U60H from Taiwan Semiconductor is a 60 V, 3 A low forward voltage trench Schottky rectifier in SOD-123HE package, featuring 0.49 V typical VF at 3 A / 25°C and 80 A peak surge capability; used for reverse battery protection and freewheeling in automotive lighting and DC/DC converters.
For engineers reviewing the TSSE3U60H datasheet, TSSE3U60H pinout, TSSE3U60H application, or TSSE3U60H equivalent, key selection criteria include its AEC-Q101 qualification, 150°C max junction temperature, J-STD-020 Level 1 moisture sensitivity, and cathode-band polarity marking on the SOD-123HE case.
Technical Context
This device implements a single-die trench Schottky structure optimized for low conduction loss and high thermal stability. Its 0.43 V typical forward voltage at 3 A and 125°C enables efficient operation in thermally constrained automotive environments.
The SOD-123HE package delivers 23°C/W junction-to-lead thermal resistance and supports reflow soldering per J-STD-002. Polarity is unambiguously indicated by a cathode band, and the device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
Key Specifications

Applications
| Reverse Battery Protection | Automotive LED Lighting |
|---|---|
Use Scenario: Prevents damage to vehicle electronics when battery terminals are accidentally reversed during jump-start or service. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power input rail. Use Value: 60 V VRRM provides 2× margin over 24 V nominal systems; 0.49 V VF minimizes voltage drop and heat generation at 3 A load. | Use Scenario: Powering high-brightness LED arrays in headlamps, DRLs, and interior lighting with PWM dimming. IC Role / Device Role / Timing Role: Freewheeling path for inductive current during MOSFET turn-off in buck/boost LED drivers. Use Value: Low 0.43 V VF at 125°C reduces thermal stress on adjacent driver ICs and improves lumen maintenance. |
| DC/DC Converter Output Rectification | Low-Voltage Inverter Freewheeling |
Use Scenario: Secondary-side rectification in isolated 12 V → 3.3 V or 5 V flyback converters for infotainment and ADAS modules. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive designs where gate drive complexity is avoided. Use Value: 3 A IF rating supports up to 15 W output; 70 °C/W RθJA enables natural convection cooling on 2-layer boards. | Use Scenario: Bidirectional current clamping in H-bridge motor inverters for HVAC actuators and seat controls. IC Role / Device Role / Timing Role: Freewheeling diode across each half-bridge leg to recirculate inductive energy. Use Value: 80 A IFSM handles repeated motor stall currents; SOD-123HE footprint fits tight layout constraints near gate drivers. |
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-3EY60HM3 | Same 60 V VRRM, 3 A IF, but TO-277A package (larger, higher RθJA = 90 °C/W) | Requires more board space; less suitable for ultra-thin automotive modules | Preferred when higher surge margin or legacy TO-277A footprint is mandated |
| ON Semiconductor NSR3G60NXT5G | 60 V VRRM, 3 A IF, SOD-123FL package; VF = 0.52 V max @ 3 A / 25°C (higher than TSSE3U60H's 0.49 V typ) | Marginally higher conduction loss; same AEC-Q101 qualification | Acceptable where 30 mV VF penalty is tolerable and dual-sourcing is required |
Compared with VS-3EY60HM3 and NSR3G60NXT5G, TSSE3U60H offers the lowest typical forward voltage in its class and best thermal performance in the compact SOD-123HE package - critical for space-constrained, high-efficiency automotive power stages.

FAQ
What is the maximum junction temperature rating for TSSE3U60H?
The TSSE3U60H has a maximum junction temperature (TJ max) of 150°C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood environments where ambient temperatures reach 105°C, provided thermal design maintains junction temperature below 150°C. The TSSE3U60H datasheet specifies derating curves confirming usable current down to ~1.7 A at 100°C ambient.
Is TSSE3U60H qualified for automotive applications?
Yes, TSSE3U60H is AEC-Q101 qualified and explicitly listed in TSC's automotive-grade product portfolio. It undergoes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - all aligned with automotive reliability requirements. The device is deployed in production car lighting and body control modules.
What does the marking code 'E3U60' indicate on TSSE3U60H?
The marking code 'E3U60' laser-etched on the TSSE3U60H case identifies the specific 60 V variant within the TSSE3UxxH family. It distinguishes TSSE3U60H from TSSE3U45H ('E3U45') and confirms the device's rated repetitive peak reverse voltage is 60 V, as defined in the Absolute Maximum Ratings table.
How does the forward voltage of TSSE3U60H compare at elevated temperature?
At 3 A and 125°C, TSSE3U60H exhibits a typical forward voltage of 0.43 V (max 0.52 V), which is lower than its 25°C value of 0.49 V (max 0.58 V). This negative temperature coefficient - inherent to Schottky diodes - improves thermal stability in high-load automotive applications, reducing risk of thermal runaway.
What is the moisture sensitivity level (MSL) of TSSE3U60H?
TSSE3U60H has a moisture sensitivity level of MSL 1 per J-STD-020, meaning it is not sensitive to moisture-induced damage during reflow soldering. No dry-packaging, baking, or floor-life tracking is required prior to assembly - simplifying manufacturing logistics for high-volume automotive PCB assembly.
