Product details
Overview
SS110HR3G from Taiwan Semiconductor is a 1 A, 100 V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring 0.80 V forward voltage at 1 A and 100 μA reverse leakage at rated VR and 25°C, optimized for high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the SS110HR3G datasheet, SS110HR3G pinout, SS110HR3G application, or SS110HR3G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), forward surge capability (40 A), thermal resistance (28 °C/W junction-to-lead), and RoHS/halogen-free compliance for industrial and consumer power designs.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its low VF and high IFSM support high-frequency switching topologies where conduction loss and transient robustness are critical.
Rated for TJ = –55°C to +150°C operation, it delivers stable performance across wide temperature ranges, with RθJA = 88 °C/W and RθJL = 28 °C/W enabling reliable thermal management in compact layouts without forced airflow.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS110HE3/5BT | Same VRRM (100 V), IF (1 A), and DO-214AC package; VF = 0.80 V at 1 A, but IR = 200 μA at 25°C (vs. 100 μA for SS110HR3G) | Slightly higher leakage may affect ultra-low-power standby circuits | Select SS110HE3/5BT when cost priority outweighs minimal leakage difference |
| SB1100-TB | 100 V, 1 A, DO-214AC; VF = 0.85 V at 1 A; IR = 100 μA at 25°C; RθJL = 30 °C/W (vs. 28 °C/W) | Marginally higher conduction loss and thermal resistance reduce efficiency in thermally constrained designs | Choose SB1100-TB only if SS110HR3G is unavailable and layout allows extra 2 °C/W thermal margin |
Compared with SS110HE3/5BT and SB1100-TB, SS110HR3G offers the lowest combination of forward voltage (0.80 V), reverse leakage (100 μA), and junction-to-lead thermal resistance (28 °C/W), making it optimal for thermally sensitive, high-reliability power conversion stages.

FAQ
What is the maximum junction temperature rating for SS110HR3G?
The SS110HR3G has a maximum junction temperature (TJ max) of +150°C, verified per TSC's R2305 datasheet revision. This rating allows operation in high-ambient environments such as enclosed power supplies or automotive cabin-mounted modules. Derating curves confirm usable current capacity down to 0.5 A at 125°C ambient with standard PCB copper. The SS110HR3G must not exceed this limit to maintain reliability and parametric stability.
Does SS110HR3G meet RoHS and halogen-free requirements?
Yes, SS110HR3G is RoHS compliant and halogen-free, as explicitly stated in the "FEATURES" section of the official TSC datasheet (Version R2305). It contains no brominated flame retardants or chlorine-based compounds, satisfying IEC 61249-2-21 and JEDEC J-STD-020 standards. This makes SS110HR3G suitable for export to EU, Japan, and other regulated markets requiring strict material declarations.
What is the forward voltage of SS110HR3G at 1 A and 100°C junction temperature?
Per the Electrical Specifications table in the TSC SS12–SS115 datasheet (R2305), the SS110HR3G exhibits a typical forward voltage of 0.70 V at IF = 1 A and TJ = 100°C. This value reflects reduced conduction loss at elevated temperatures compared to room-temperature operation (0.80 V), supporting stable performance across thermal transients in real-world power applications.
Is SS110HR3G suitable for use in high-frequency switching circuits?
Yes, SS110HR3G is well-suited for high-frequency switching circuits due to its Schottky architecture, which eliminates minority-carrier storage delay. With a critical rate of rise of off-state voltage (dv/dt) rated at 10,000 V/μs and low junction capacitance (<100 pF at 4 V), the SS110HR3G supports clean turn-off in PWM frequencies up to 1 MHz, especially in flyback and resonant converter topologies.
What packaging format is used for SS110HR3G, and how many units are supplied per reel?
SS110HR3G is supplied in DO-214AC (SMA) package on 7,500-unit tape-and-reel format, as confirmed in the Ordering Information section of the TSC datasheet (R2305). The reel complies with EIA-481-D standards, and the device marking includes "SS110" plus date and factory codes. This packaging supports high-speed pick-and-place placement with zero manual handling required.
