Product details
Overview
SK16B R5G from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.75V forward voltage at 1A and 5µA reverse current at 25°C, designed for high-efficiency DC/DC converters and AC/DC adapters.
For engineers reviewing the SK16B R5G datasheet, SK16B R5G pinout, SK16B R5G application, or SK16B R5G equivalent, key selection criteria include its 60V VRRM rating, 30A IFSM surge capability, 125°C maximum junction temperature, and SMB package compatibility with automated SMT assembly lines.
Technical Context
The SK16B R5G implements a single-die Schottky junction optimized for low forward voltage drop and fast switching recovery, enabling high-frequency operation in switch-mode power supplies without minority-carrier storage delay. Its guard ring structure provides overvoltage protection while maintaining stable reverse leakage up to 125°C.
Thermal performance is defined by a 25°C/W junction-to-lead thermal resistance, supporting continuous 1A conduction under typical PCB copper land patterns. The device meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance requirements.

| IR @ 60V, 25°C | 5 µA - Ultra-low reverse leakage preserves standby power budget in energy-sensitive adapters |
| IFSM (8.3ms) | 30 A - Withstands inrush surges during cold-start of LED drivers and industrial power modules |
| TJ max | 125 °C - Enables operation in sealed enclosures without forced airflow in lighting applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16-E3/5AT (Vishay) | Same 60V VRRM, 1A IF, but VF = 0.72V typ; slightly lower IR (2µA @ 25°C) | Better leakage performance at elevated temperature; tighter VF distribution for binning-critical designs | Preferred when <3µA IR at 100°C is required; same SMB footprint |
| SB160-TB (ON Semiconductor) | 60V VRRM, 1A IF, VF = 0.78V typ; higher IR (10µA @ 25°C); TJ max = 125°C | Higher conduction loss increases thermal stress in sealed enclosures | Acceptable for cost-sensitive industrial controls where 0.03V VF delta is tolerable |
Compared with SS16-E3/5AT and SB160-TB, the SK16B R5G offers balanced VF/IR trade-off and guaranteed guard ring protection-critical for unregulated adapter inputs-while maintaining full SMB mechanical compatibility and J-STD-020 level-1 handling.

FAQ
What is the maximum junction temperature rating for SK16B R5G?
The SK16B R5G has a maximum junction temperature (TJ max) of 125°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet M2212. This rating applies under continuous 1A forward current with proper PCB thermal design. Exceeding 125°C risks irreversible degradation of the Schottky junction and increased reverse leakage in the SK16B R5G.
Does SK16B R5G have a guard ring structure?
Yes, the SK16B R5G incorporates a guard ring for overvoltage protection, explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet M2212. This structure enhances ruggedness against transient voltage spikes in AC/DC adapters and improves long-term reliability of the SK16B R5G without requiring external snubbers.
What is the forward voltage of SK16B R5G at 1A and 25°C?
The forward voltage (VF) of SK16B R5G is 0.75V maximum at IF = 1A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table in the M2212 datasheet. This value is measured under pulse test conditions (PW = 0.3ms) and defines conduction loss behavior in the SK16B R5G during normal operation.
Is SK16B R5G compliant with RoHS and halogen-free standards?
Yes, SK16B R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the FEATURES section of the Taiwan Semiconductor M2212 datasheet. These certifications apply to the molding compound and plating system used in the SK16B R5G, supporting environmental compliance for export to EU and other regulated markets.
What packaging format is used for SK16B R5G?
The SK16B R5G is supplied in DO-214AA (SMB) package with tape-and-reel packaging: 3,000 units per reel, as specified in the ORDERING INFORMATION section of the M2212 datasheet. This format ensures compatibility with standard SMT pick-and-place equipment and supports automated assembly of the SK16B R5G in high-volume production.
