Taiwan Semiconductor Corporation SS110 R3G

Overview

SS110 R3G from Taiwan Semiconductor is a 1A, 100V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, optimized for high-efficiency DC/DC conversion with 0.80V forward voltage at 1A and 25°C, 100μA reverse leakage at rated VR and 25°C, and 40A peak surge current capability. It serves as a primary output rectifier in compact off-line SMPS and adapter designs.

For engineers reviewing the SS110 R3G datasheet, SS110 R3G pinout, SS110 R3G application, or SS110 R3G equivalent, key selection criteria include verified V_RRM = 100 V, I_F = 1 A continuous rating, T_J(max) = 150 °C operation, DO-214AC mechanical compatibility, and cathode-band polarity marking per JEDEC standard.

Technical Context

The SS110 R3G implements a single-die Schottky junction structure with guard ring overvoltage protection, enabling robust transient immunity without external clamping. Its low V_F and high dV/dt rating (10,000 V/µs) support high-frequency switching topologies up to several hundred kHz.

Thermal performance is defined by R_θJL = 28 °C/W and R_θJA = 88 °C/W, supporting 1A continuous conduction in standard PCB layouts with minimal copper area. Moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to reflow.

FAQ

What is the maximum junction temperature rating for SS110 R3G?

The SS110 R3G has a maximum junction temperature (T_J(max)) of +150°C, confirmed in the Absolute Maximum Ratings table. This rating allows the SS110 R3G to operate reliably in thermally constrained environments such as enclosed TV power supplies or sealed industrial DC/DC modules without forced cooling. The SS110 R3G maintains specified electrical parameters up to this limit when derated per its forward current derating curve.

Does SS110 R3G have a halogen-free and RoHS-compliant construction?

Yes, the SS110 R3G is both halogen-free and RoHS-compliant, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version R2305). These compliance attributes are verified per IEC 61249-2-21 and EU Directive 2011/65/EU, making the SS110 R3G suitable for export to EU, Japan, and other regulated markets requiring full substance declarations.

What is the forward voltage of SS110 R3G at 1A and 100°C junction temperature?

The SS110 R3G exhibits a typical forward voltage of 0.70 V at 1A and 100°C junction temperature, per the ELECTRICAL SPECIFICATIONS table. This value is critical for thermal modeling in high-ambient applications like monitors or industrial controls, where elevated operating temperatures reduce V_F versus room-temperature measurements-confirming lower conduction loss under real-world conditions.

Is SS110 R3G suitable for use in automotive infotainment power supplies?

The SS110 R3G is not qualified for automotive applications per AEC-Q101, and Taiwan Semiconductor's documentation explicitly states these devices are "not designed for use in medical, life-saving, or life-sustaining applications." While the SS110 R3G meets industrial temperature and reliability standards, it lacks automotive-grade qualification, traceability, and extended temperature validation required for infotainment systems operating across -40°C to +125°C ambient.

What packaging format is used for SS110 R3G, and how many units are included per reel?

The SS110 R3G is supplied in DO-214AC (SMA) package on 7,500-unit tape-and-reel format, as specified in the ORDERING INFORMATION section. This standard SMT packaging supports high-speed pick-and-place assembly and aligns with JEDEC-compliant feeders. The reel quantity enables efficient medium-to-high volume production runs without frequent changeovers.
