Product details
Overview
SK16BHR5G 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 SK16BHR5G datasheet, SK16BHR5G pinout, SK16BHR5G application, or SK16BHR5G equivalent, key selection criteria include its 60V VRRM rating, 30A IFSM surge capability, 125°C maximum junction temperature, and SMB package compatibility with automated placement systems.
Technical Context
This Schottky rectifier uses a single-die construction optimized for low forward voltage drop and fast switching, enabling high-frequency operation without minority-carrier recovery delay. Its guard ring structure provides overvoltage protection while maintaining stable reverse leakage up to 125°C.
The device meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance, with matte tin-plated leads solderable per J-STD-002. Thermal resistance from junction to lead is 25°C/W, supporting reliable power dissipation in compact layouts.

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) at 1A; slightly lower IR (200µA @ 25°C) | Identical SMB package; identical thermal resistance; preferred where lowest possible VF is critical | Select SS16-E3/5AT when optimizing for ultra-low conduction loss in battery-powered systems |
| SB160 (ON Semiconductor) | 60V VRRM, 1A IF, VF = 0.75V (max) at 1A; IR = 500µA (max) at 25°C - matches SK16BHR5G specs exactly | DO-214AA package; same pinout and footprint; RoHS/halogen-free compliant | SB160 is a direct form-fit-function alternative with identical electrical and mechanical specifications |
Compared with SS16-E3/5AT and SB160, the SK16BHR5G offers identical baseline performance to SB160 and slightly higher VF than SS16-E3/5AT, making it optimal for cost-sensitive industrial adapters where spec margin and supply chain diversity matter more than sub-10mV VF reduction.

FAQ
What is the maximum junction temperature rating for SK16BHR5G?
The SK16BHR5G has a maximum junction temperature (TJ max) of 125°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision M2212. This rating applies under continuous DC forward current conditions and enables operation in enclosed power supplies without active cooling. Derating begins above 25°C ambient, following the forward current derating curve shown in Figure 1 of the SK12B–SK115B datasheet. The SK16BHR5G must not be operated beyond this limit to ensure long-term reliability.
Does SK16BHR5G meet RoHS and halogen-free requirements?
Yes, the SK16BHR5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor SK12B–SK115B datasheet (Version M2212). The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminals use matte tin plating without lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE. These compliance statements apply directly to the SK16BHR5G variant.
What is the forward voltage of SK16BHR5G at 1A and 25°C?
The forward voltage (VF) of SK16BHR5G is 0.75 V maximum at IF = 1 A and TJ = 25°C, per the "ELECTRICAL SPECIFICATIONS" table in the Taiwan Semiconductor SK12B–SK115B datasheet (Version M2212). This value is measured under pulse test conditions (PW = 0.3 ms), and typical VF may be lower. The SK16BHR5G's VF remains stable across its rated temperature range, supporting predictable power loss calculation in thermal design.
Is SK16BHR5G compatible with lead-free reflow soldering processes?
Yes, SK16BHR5G features matte tin-plated leads qualified per J-STD-002 for solderability, and its DO-214AA (SMB) package is rated for lead-free reflow profiles including peak temperatures up to 260°C. The device meets J-STD-020 moisture sensitivity level 1, meaning it can be placed directly after dry storage without baking. These attributes make SK16BHR5G fully compatible with standard SAC305 and SAC405 reflow processes used in modern electronics assembly lines.
What is the reverse leakage current of SK16BHR5G at rated voltage and 100°C?
At VR = 60 V and TJ = 100°C, the reverse leakage current (IR) of SK16BHR5G is 5 mA maximum, as specified in the "ELECTRICAL SPECIFICATIONS" table of the Taiwan Semiconductor SK12B–SK115B datasheet (Version M2212). This value is measured using a 30 ms pulse test. The SK16BHR5G's IR increases predictably with temperature, remaining within specification up to 125°C, where IR reaches 10 mA - critical for standby power budgeting in always-on adapters.
