Product details
Overview
SK15BHR5G from Taiwan Semiconductor is a 1A, 50V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.75V forward voltage at 1A and 5mA reverse current at 100°C, designed for high-efficiency DC/DC converters and AC/DC adapters.
For engineers reviewing the SK15BHR5G datasheet, SK15BHR5G pinout, SK15BHR5G application, or SK15BHR5G equivalent, this device offers verified thermal resistance of 25°C/W, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 - critical for automated SMT assembly and industrial power supply reliability.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 10,000 V/µs dV/dt rating supports fast-switching topologies.
Rated for junction temperatures up to +150°C and storage from –55°C to +150°C, SK15BHR5G delivers stable performance under transient surge conditions (30A IFSM, 8.3ms half-sine) and meets UL 94V-0 flammability requirements in its molded plastic case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 1 A continuous - supports compact 1A-output SMPS designs without forced cooling |
| Peak Reverse Voltage (VRRM) | 50 V - suitable for 36V nominal bus systems with 20% margin |
| Forward Voltage (VF) | 0.75 V max @ 1A, 25°C - reduces conduction loss vs. standard PN diodes |
| Surge Current (IFSM) | 30 A @ 8.3ms - withstands inrush and transient overload in adapter inputs |
| Junction-to-Lead Thermal Resistance (RθJL) | 25 °C/W - enables direct PCB copper pour heat sinking in SMB footprint |
| Reverse Current (IR) | 5 mA max @ 50V, 100°C - low leakage preserves efficiency in high-temp operation |
| Operating Junction Temp | –55°C to +150°C - qualified for extended industrial temperature range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS15H | Same DO-214AA package, 50V VRRM, but VF = 0.85V @ 1A (25°C); IR = 100 µA @ 25°C | Higher VF increases conduction loss; lower IR improves light-load efficiency | Prefer SK15BHR5G where thermal management is constrained and 100°C operation is required |
| SB150 | DO-214AA, 50V VRRM, VF = 0.72V @ 1A (25°C), but TJ max = +125°C only | Limited high-temp capability; no guard ring or JESD201 Class 2 qualification | Choose SK15BHR5G for designs requiring >125°C operation or enhanced surge robustness |
Compared with SS15H and SB150, SK15BHR5G uniquely combines 150°C junction rating, guard ring protection, and JESD201 Class 2 whisker resistance - making it optimal for thermally demanding, high-reliability industrial power stages where long-term solder joint integrity and transient immunity are mandatory.

FAQ
What is the maximum junction temperature rating for SK15BHR5G?
The SK15BHR5G has a maximum junction temperature (TJ) rating of +150°C, validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version M2212. This allows uninterrupted operation in enclosed industrial environments where board-level temperatures exceed 100°C. The SK15BHR5G maintains specified electrical parameters up to this limit when thermal design respects the 25°C/W RθJL value.
Does SK15BHR5G have a guard ring structure?
Yes, SK15BHR5G incorporates a guard ring for overvoltage protection, explicitly stated in the "FEATURES" section of the Taiwan Semiconductor datasheet. This structure enhances edge termination robustness, improving resistance to repetitive voltage transients - especially valuable in flyback converter outputs and unregulated DC bus rectification where voltage spikes occur regularly.
What is the forward voltage of SK15BHR5G at 1A and 100°C?
The forward voltage of SK15BHR5G is not explicitly specified at 100°C in the datasheet, but the typical VF curve (Fig.4) shows ~0.65V at 1A and 100°C for SK15B–SK16B variants. At 25°C, VF is ≤0.75V (max), and the device's positive temperature coefficient ensures VF decreases with rising temperature - a key Schottky characteristic confirmed in the "ELECTRICAL SPECIFICATIONS" table.
Is SK15BHR5G suitable for lead-free reflow soldering?
Yes, SK15BHR5G is qualified for lead-free reflow soldering per J-STD-002. Its matte tin-plated leads and moisture sensitivity level 1 (per J-STD-020) mean it can be placed directly into standard Pb-free reflow profiles (peak ~260°C) without baking. The DO-214AA package also complies with JEDEC standards for thermal shock resistance during repeated reflow cycles.
What packaging format is available for SK15BHR5G?
SK15BHR5G is supplied in tape-and-reel packaging: 3,000 units per reel, compatible with high-speed pick-and-place equipment. The ordering code SK15BHR5G follows Taiwan Semiconductor's standard nomenclature where "HR5G" denotes halogen-free, RoHS-compliant, green compound variant - confirmed in the "ORDERING INFORMATION" section of the datasheet.
