Product details
Overview
HS3F V7G from Taiwan Semiconductor is a 3A, 300V high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.0V max forward voltage at 3A, 150A peak surge current, and 50ns reverse recovery time - deployed in switching-mode power supplies for telecom infrastructure.
For engineers reviewing the HS3F V7G datasheet, HS3F V7G pinout, HS3F V7G application, or HS3F V7G equivalent, key selection criteria include repetitive peak reverse voltage (300V), thermal resistance (60°C/W), junction temperature range (–55°C to +150°C), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for high-frequency operation. Its low-profile DO-214AB (SMC) package supports automated placement and meets UL 94V-0 flammability requirements with matte tin-plated leads.
The HS3F V7G delivers fast recovery (trr ≤ 50 ns) and low forward voltage drop (VF ≤ 1.0 V @ 3A, 25°C), enabling high efficiency in DC-DC converters and freewheeling paths where switching losses must be minimized at frequencies up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines safe operating window in 24–48V input SMPS front-end rectification. |
| IF | 3 A continuous - Rated average forward current under specified thermal conditions; supports compact heatsinking in space-constrained 30–60W adapters. |
| IFSM | 150 A (8.3ms half-sine) - Peak non-repetitive surge capability; withstands inrush currents during cold-start of industrial power modules. |
| VF | ≤1.0 V @ 3A, 25°C - Low conduction loss reduces power dissipation by ~30% vs. standard 1N54xx series, improving thermal margin in sealed enclosures. |
| trr | ≤50 ns - Fast reverse recovery minimizes switching loss and EMI generation in 100–500 kHz flyback and forward converter topologies. |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance on standard FR-4 PCB with 1-inch² copper pad; enables derating to 2.1A at 70°C ambient without forced air. |
| TJ Range | –55°C to +150°C - Wide operating junction temperature range supports deployment in automotive under-hood auxiliary supplies and outdoor telecom equipment. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-indicated by molded band, matte tin-plated leads, JESD201 Class 2 whisker compliant, weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return); requires adequate copper area for thermal relief. |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Connected to output rail or capacitor positive; cathode band orientation must match PCB silkscreen to prevent assembly error. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in humid environments (e.g., base station cabinets), eliminating need for conformal coating in IPC Class 2 applications. |
| Low profile SMC package | Height ≤ 2.6 mm enables use in ultra-thin AC-DC adapters and PoE-powered devices where Z-height is constrained by mechanical housing. |
| J-STD-020 Level 1 MSL | Zero bake requirement before reflow; compatible with standard lead-free reflow profiles (peak 260°C), reducing manufacturing cost and process complexity. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; suitable for export to EU, Japan, and South Korea without substance-of-concern reporting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH03-M3/54 | Same DO-214AB package, 3A/300V, VF = 1.05V @ 3A, trr = 55ns, RθJA = 65°C/W | Slightly higher VF and trr; lower thermal performance limits continuous current in high-ambient designs. | Preferred where Vishay supply chain alignment or dual-sourcing is required; verify layout thermal relief matches 65°C/W derating curve. |
| ON Semiconductor MUR330 | DO-201AD (Axial), 3A/300V, VF = 1.15V @ 3A, trr = 50ns, RθJA = 75°C/W | Through-hole package incompatible with SMT lines; higher VF increases conduction loss by ~150mW at 3A. | Only suitable for legacy through-hole designs or prototyping; not recommended for new SMT production due to assembly incompatibility and thermal penalty. |
Compared with VS-3EYH03-M3/54 and MUR330, the HS3F V7G offers superior thermal resistance (60°C/W), lower forward voltage (≤1.0V), and native SMT compatibility - making it optimal for high-density, thermally constrained telecom and industrial power modules requiring long-term reliability without rework.

FAQ
What is the maximum junction temperature rating for HS3F V7G?
The HS3F V7G has a maximum junction temperature (TJ MAX) of +150°C, with a minimum operating temperature of –55°C. This wide range supports deployment in harsh environments such as outdoor telecom base stations and under-hood automotive electronics. The device's thermal performance (RθJA = 60°C/W) allows reliable operation at full 3A current up to 70°C ambient when mounted on a standard 1-inch² copper pad.
Does HS3F V7G meet RoHS and halogen-free requirements?
Yes, HS3F V7G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating materials meet EU RoHS Directive 2011/65/EU restrictions. This makes HS3F V7G suitable for export to regulated markets including the EU, Japan, and South Korea without additional substance declarations.
What is the reverse recovery time (trr) specification for HS3F V7G?
The HS3F V7G has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic minimizes switching loss and EMI in high-frequency converters operating above 100 kHz. The value is confirmed in the official Taiwan Semiconductor K2102 datasheet and applies specifically to the HS3F variant within the HS3x family.
Is HS3F V7G pin-compatible with other devices in the HS3x series?
Yes, all HS3x devices - including HS3A, HS3B, HS3D, HS3F, HS3G, HS3J, HS3K, and HS3M - share identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout. The only differences are rated VRRM (50V to 1000V) and associated VF/trr values. This allows design reuse across voltage grades without PCB revision.
What packaging format is used for HS3F V7G?
HS3F V7G is supplied in tape-and-reel format with 3,000 units per reel, compatible with standard SMT pick-and-place equipment. The DO-214AB (SMC) package features matte tin-plated leads that comply with J-STD-002 solderability requirements and JESD201 Class 2 whisker testing. Moisture sensitivity level is J-STD-020 Level 1, meaning no dry-pack or baking is required prior to reflow.
