Product details
Overview
HS5B R7G from Taiwan Semiconductor is a 5A, 100V glass-passivated surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage drop (1.00 V at 5A, 25°C), 150A surge rating, and 50 ns reverse recovery time. It serves as a high-efficiency freewheeling diode in switching-mode power supplies for telecom and computing applications.
For engineers reviewing the HS5B R7G datasheet, HS5B R7G pinout, HS5B R7G application, or HS5B R7G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (60 °C/W), junction temperature range (–55 to +150 °C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This single-die, unidirectional silicon rectifier uses a glass-passivated PN junction to achieve stable reverse blocking and fast recovery. Its DO-214AB (SMC) package supports automated placement and provides UL 94V-0 rated molding compound with matte tin-plated leads compliant with J-STD-002 solderability.
The device operates across –55°C to +150°C junction temperature, with typical junction capacitance of 80 pF at 1 MHz and 4.0 V reverse bias. Reverse leakage remains ≤10 µA at 25°C and ≤250 µA at 125°C under rated reverse voltage.
Key Specifications

| IFSM | 150 A - non-repetitive surge current capability (8.3 ms half-sine), critical for inrush protection |
| VF @ 5A, 25°C | 1.00 V - forward voltage drop determining conduction loss and thermal load in DC/DC converters |
| trr | 50 ns - reverse recovery time affecting switching losses and EMI in high-frequency SMPS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06D (STMicroelectronics) | 600 V VRRM, 1.75 V VF @ 5 A, 60 ns trr, TO-277 package | Higher voltage rating suits 400 V bus designs; larger footprint than SMC | Choose when >100 V reverse margin required and board space allows TO-277 |
| MBR5100CT (ON Semiconductor) | 100 V VRRM, dual common-cathode Schottky, 0.85 V VF @ 5 A, no trr spec | Lower VF reduces conduction loss but limited to ≤125°C TJ; not suitable for 150°C environments | Prefer for <125°C ambient applications where ultra-low VF outweighs temperature limit |
Compared with STTH5L06D and MBR5100CT, the HS5B R7G offers optimal balance of 100 V rating, 150°C operation, SMC footprint, and 50 ns trr-making it ideal for space-constrained, high-temperature telecom and server power stages where reliability and manufacturability are prioritized.

FAQ
What is the maximum junction temperature rating for HS5B R7G?
The HS5B R7G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in thermally demanding environments such as enclosed telecom power modules. Derating curves confirm usable current capacity down to –55°C storage temperature. The HS5B R7G must be mounted on PCBs with adequate copper area to maintain junction temperature within this limit under full 5 A load.
Does HS5B R7G have a specified reverse recovery time (trr)?
Yes, the HS5B R7G has a specified reverse recovery time (trr) of 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table for the HS5A–HS5G group. The HS5B R7G's 50 ns trr supports efficient operation in 300–500 kHz switching converters, reducing switching losses compared to slower rectifiers. No derating or conditional notes apply to this parameter at 25°C ambient.
Is HS5B R7G RoHS and halogen-free compliant?
Yes, HS5B R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These compliance attributes are certified for the DO-214AB (SMC) package variant shipped as HS5B R7G, with no exemptions or exceptions noted in official documentation.
What does the 'R7G' suffix indicate in HS5B R7G?
The 'R7G' suffix in HS5B R7G denotes Taiwan Semiconductor's internal date code and factory marking: 'R7' corresponds to week 7 of 2023 (or 2033), and 'G' identifies the fabrication facility. This coding aligns with the Marking Diagram on page 5 of the HS5A–HS5M datasheet (Version K2102). The base device remains electrically and mechanically identical to HS5B; R7G is a traceable production lot identifier-not a functional variant.
Can HS5B R7G replace HS5B without design changes?
Yes, HS5B R7G is a direct form-fit-function replacement for HS5B, sharing identical electrical specifications, DO-214AB (SMC) package dimensions, pinout, thermal performance, and compliance certifications. The 'R7G' suffix reflects only traceable manufacturing data-not a revision change. No PCB layout, thermal design, or schematic modification is required when substituting HS5B R7G for HS5B in existing designs.
