Product details
Overview
SK110BHR5G from Taiwan Semiconductor is a 1 A, 100 V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.85 V forward voltage at 1 A and 100 µA reverse leakage at rated VR and 25°C, used in switching mode power supplies and DC-DC converters where low conduction loss and fast recovery are required.
For engineers reviewing the SK110BHR5G datasheet, SK110BHR5G pinout, SK110BHR5G application, or SK110BHR5G equivalent, key selection criteria include peak reverse voltage rating (100 V), thermal resistance (25 °C/W), surge current capability (30 A), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial and adapter designs.
Technical Context
This device implements a single-die Schottky junction with guard ring structure for enhanced overvoltage robustness and meets JESD201 Class 2 whisker resistance. Its 10,000 V/µs critical dV/dt rating supports stable operation in high-speed switching environments.
Designed for surface-mount assembly, SK110BHR5G uses matte tin-plated leads compliant with J-STD-002 solderability and carries moisture sensitivity level 1 per J-STD-020 - eliminating bake requirements prior to reflow.

Use Value: 0.85 V VF reduces conduction loss by ~35% vs. comparable 100 V PN diodes, improving efficiency at full load. | Use Scenario: Secondary-side rectification in universal-input wall adapters. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated DC to USB or low-voltage logic rails. Use Value: 100 µA IR at 25°C minimizes no-load input power, aiding Energy Star Tier 2 compliance. |
| LED Driver Converter | Industrial DC-DC Module |
Use Scenario: Constant-current regulation loop output stage in isolated LED drivers. IC Role / Device Role / Timing Role: Synchronous rectifier alternative in quasi-resonant topologies. Use Value: 150°C TJ max allows operation in enclosed luminaires with ambient temperatures up to 85°C. | Use Scenario: Input protection and output rectification in 12 V/24 V industrial DC-DC modules. IC Role / Device Role / Timing Role: Reverse-polarity and backfeed protection diode on input rail. Use Value: 10,000 V/µs dV/dt rating prevents false turn-on during fast transients in motor drive or PLC I/O circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS110H from Diodes Inc. | Same 100 V VRRM, 1 A IF, but VF = 0.87 V (max) at 1 A; RθJL = 28 °C/W | Slightly higher thermal resistance limits power density in compact layouts | Preferred when legacy SS110H footprint compatibility is required |
| SB1100 from ON Semiconductor | 100 V VRRM, 1 A IF, VF = 0.82 V (typ) at 1 A; IR = 200 µA at 100 V/25°C | Higher leakage may impact light-load efficiency in battery-backed systems | Selected where lower forward drop outweighs leakage sensitivity |
Compared with SK110BHR5G, SS110H offers identical voltage/current ratings but slightly higher thermal resistance, while SB1100 delivers lower typical VF at the cost of doubled reverse leakage - requiring trade-off analysis between conduction loss and standby power in final system validation.
