Product details
Overview
HS3FB from Taiwan Semiconductor is a 3A, 300V repetitive peak reverse voltage surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A and 50ns max reverse recovery time, used for high-efficiency AC/DC conversion in compact power adapters.
For engineers reviewing the HS3FB datasheet, HS3FB pinout, HS3FB application, or HS3FB equivalent, key selection criteria include its 300V VRRM, 100A IFSM, 60°C/W RθJA, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance for industrial-grade SMPS design.
Technical Context
The HS3FB is a single-die, glass-passivated, fast-recovery rectifier optimized for switching-mode power supplies operating up to 150°C junction temperature. Its 50ns trr and low 1.0V VF at 3A enable reduced conduction and switching losses in high-frequency flyback and forward converters.
Designed with matte tin-plated leads compliant with J-STD-002 and moisture sensitivity level 1 per J-STD-020, the HS3FB supports automated SMT placement and reflow without preconditioning, while its UL 94V-0 molding compound ensures flame-retardant reliability in space-constrained consumer electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum non-repetitive reverse blocking voltage; defines usable input voltage range in bridge or single-diode rectification stages |
| IF | 3 A - Continuous average forward current; determines thermal derating margin in 75°C ambient adapter designs |
| VF @ 3A | ≤1.0 V - Forward voltage drop at rated current; directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| trr | ≤50 ns - Reverse recovery time; enables stable operation at >100 kHz switching frequencies with minimal switching noise |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; sets minimum PCB copper area requirement for 3A continuous load at 70°C ambient |
| IFSM | 100 A - Non-repetitive surge current rating; withstands inrush currents during cold-start of 100W-class power supplies |
| CJ | 80 pF @ 4V - Junction capacitance; influences EMI generation and snubber sizing in high-dv/dt applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR330 | Same 3A/300V rating, but 35ns trr and 1.2V VF; TO-220AC package vs SMB | Requires through-hole assembly and heatsink; unsuitable for ultra-thin adapters | Select when lower trr outweighs SMT compatibility and board space constraints |
| Vishay VS-3EY30 | 3A/300V, 60ns trr, 1.15V VF, same DO-214AA package, but not halogen-free | Lacks IEC 61249-2-21 compliance; restricted in EU medical/consumer shipments | Select only for cost-sensitive non-regulated markets where halogen-free is not mandated |
Compared with MUR330 and VS-3EY30, the HS3FB uniquely combines SMB SMT compatibility, 1.0V low VF, halogen-free compliance, and moisture level 1-making it optimal for high-volume, space-constrained, globally shipped power adapters.

FAQ
What is the maximum junction temperature rating for HS3FB?
The HS3FB has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version L2102. This allows reliable operation in enclosed power adapters with limited airflow, provided PCB thermal design maintains junction temperature below this limit during continuous 3A load. Derating curves confirm usable current down to 1.5A at 125°C ambient.
Does HS3FB support lead-free reflow soldering?
Yes, HS3FB supports lead-free reflow soldering per J-STD-002. Its matte tin-plated leads are qualified for peak temperatures up to 260°C, and its moisture sensitivity level 1 eliminates bake preconditioning. The DO-214AA (SMB) package is compatible with standard IPC-7095 SMT profiles, and the UL 94V-0 molding compound resists delamination during thermal cycling.
What is the reverse leakage current specification for HS3FB at elevated temperature?
Per the Electrical Specifications table in the Taiwan Semiconductor datasheet, HS3FB exhibits ≤250 μA reverse current (IR) at rated VR and TJ = 100°C. At 25°C, leakage is ≤10 μA. This low leakage preserves efficiency in high-impedance bias networks and reduces standby power loss in energy-efficient adapters complying with DOE Level VI or EU CoC Tier 2 standards.
Is HS3FB pin-compatible with other devices in the HS3x family?
Yes, all HS3x devices-including HS3AB, HS3BB, HS3DB, HS3FB, HS3GB, HS3JB, HS3KB, and HS3MB-share identical DO-214AA (SMB) package dimensions, pinout, and thermal pad layout. Voltage ratings differ only in die construction; mechanical mounting, solder stencil, and PCB footprint are fully interchangeable across the family for BOM flexibility and design reuse.
How does HS3FB's junction capacitance affect EMI performance in high-frequency SMPS?
HS3FB's typical junction capacitance is 80 pF at 4V reverse bias, measured at 1 MHz. This value directly influences high-frequency ringing amplitude and EMI filter attenuation requirements. In 200–500 kHz flyback converters, this CJ contributes to snubber network design and helps suppress dv/dt-induced common-mode noise-especially when paired with its 50 ns trr to minimize abrupt current collapse.
