Product details
Overview
SK13BHR5G from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.50V forward voltage at 1A/25°C, 30A surge capability, and guard ring overvoltage protection-designed for high-efficiency switching power supplies.
For engineers reviewing the SK13BHR5G datasheet, SK13BHR5G pinout, SK13BHR5G application, or SK13BHR5G equivalent, key selection criteria include its 30V VRRM, low VF, SMB thermal performance (RθJL = 25°C/W), and JESD201 Class 2 whisker resistance for reliable automated assembly in industrial adapters and lighting converters.
Technical Context
This discrete Schottky diode operates as a unidirectional power rectifier with single-die configuration and cathode-band polarity marking. Its junction temperature range spans –55°C to +150°C, supporting operation in thermally demanding converter stages where fast recovery and low conduction loss are critical.
The device delivers 30A non-repetitive surge current (8.3ms half-sine), exhibits 10,000 V/µs dV/dt rating, and maintains ≤500 µA reverse leakage at 30V/25°C-enabling stable performance in high-frequency SMPS front-end and DC-DC output rectification without snubber networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13-E3/5AT (Vishay) | Same 30V VRRM, 1A IF, but VF = 0.52V @ 1A; SMB package, no guard ring | Lacks guard ring; slightly higher VF increases conduction loss in high-duty-cycle converters | Acceptable where transient immunity is less critical and 20mV VF penalty is tolerable |
| SB130 (ON Semiconductor) | 30V VRRM, 1A IF, VF = 0.55V @ 1A; DO-214AA, no JESD201 Class 2 validation | No whisker resistance certification; may require process controls for long-life automotive-adjacent use | Suitable for cost-sensitive consumer designs with shorter lifecycle expectations |
Compared with SS13-E3/5AT and SB130, SK13BHR5G provides superior transient robustness via guard ring, lower VF, and verified whisker resistance-making it preferred for industrial adapters and lighting where reliability and thermal stability are prioritized over minimal BOM cost.

FAQ
What is the maximum junction temperature rating for SK13BHR5G?
The SK13BHR5G has a maximum junction temperature (TJ) of +150°C, allowing uninterrupted operation in thermally constrained environments such as enclosed LED drivers or industrial power modules. This rating is validated per TSC's M2212 specification and enables full 1A current delivery without derating up to 85°C ambient when mounted on adequate copper area. The SK13BHR5G's thermal design leverages its 25°C/W RθJL to maintain safe junction temperatures under continuous load.
Does SK13BHR5G have a guard ring structure, and why does it matter?
Yes, SK13BHR5G incorporates a guard ring for enhanced edge termination and overvoltage protection. This feature improves ruggedness against transient voltage spikes and localized electric field concentration at the die periphery-critical in SMPS applications with fast-switching MOSFETs. Unlike basic Schottky diodes, the guard ring in SK13BHR5G reduces risk of premature breakdown during line surges or hot-plug events, directly contributing to field reliability in adapters and lighting systems.
What is the forward voltage of SK13BHR5G at 1A and 100°C junction temperature?
The forward voltage (VF) of SK13BHR5G is not explicitly specified at 100°C in the M2212 datasheet; however, typical VF increases with temperature, and curves in Figure 4 show a rise from 0.50V at 25°C to approximately 0.42V at 100°C for SK12B–SK14B variants. Since SK13BHR5G belongs to this group, its VF at 1A/100°C is estimated at ~0.42V-lower than at room temperature due to Schottky's negative temperature coefficient. This behavior improves thermal stability in high-ambient applications.
Is SK13BHR5G compliant with JESD201 whisker testing?
Yes, SK13BHR5G meets JESD201 Class 2 whisker test requirements, confirming resistance to tin whisker growth under thermal-humidity stress. This qualification ensures long-term solder joint integrity in products subject to thermal cycling, such as outdoor lighting or industrial controllers. The matte tin plating and process controls applied to SK13BHR5G support reliable automated assembly and extended field life without whisker-induced short circuits.
What packaging and reel quantity is offered for SK13BHR5G?
SK13BHR5G is supplied in DO-214AA (SMB) package on 3,000-piece tape-and-reel format, optimized for high-speed pick-and-place assembly. The reel complies with EIA-481 standards, and the device marking "SK13B" is laser-etched on the cathode-end surface with green compound (G) and date code (YW) per TSC's M2212 revision. No alternate packaging (e.g., bulk or ammo pack) is specified for SK13BHR5G in official documentation.
