Product details
Overview
HS3B V7G from Taiwan Semiconductor is a 100 V, 3 A surface-mount high-efficiency fast recovery rectifier in DO-214AB (SMC) package, featuring 1.0 V forward voltage at 3 A and 50 ns reverse recovery time, used for freewheeling and high-frequency rectification in switching-mode power supplies.
For engineers reviewing the HS3B V7G datasheet, HS3B V7G pinout, HS3B V7G application, or HS3B V7G equivalent, key selection criteria include peak repetitive reverse voltage (100 V), surge current capability (150 A), thermal resistance (60 °C/W), junction temperature range (−55 to +150 °C), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for high-frequency switching applications. Its low forward voltage drop and fast reverse recovery time (50 ns) minimize conduction and switching losses in DC-DC converters and inverters.
The DO-214AB (SMC) package supports automated placement and provides robust thermal performance with 60 °C/W junction-to-ambient resistance. Polarity is marked by a cathode band, and terminals are matte tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage; defines safe blocking capability in flyback or boost topologies |
| IF | 3 A - average forward current; determines continuous power-handling capacity at rated case temperature |
| IFSM | 150 A - non-repetitive peak surge current; withstands inrush and fault transients without failure |
| VF @ 3A | 1.0 V - forward voltage drop at rated current; directly impacts conduction loss and thermal design |
| trr | 50 ns - reverse recovery time; enables efficient operation up to several hundred kHz switching frequencies |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance; guides heatsinking requirements on standard PCB copper |
| TJ Range | −55 to +150 °C - operating junction temperature range; supports industrial and telecom environments |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, low-profile, moisture sensitivity level 1 (per J-STD-020), UL 94V-0 molding compound, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Current entry point during forward conduction | Connected to lower-potential side of load or switch node in buck/flyback configurations |
| Cathode | Current exit point during forward conduction; polarity-marked terminal | Connected to output rail or ground return; critical for correct orientation in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances reliability and leakage stability under humid or high-bias stress conditions |
| Low VF (1.0 V @ 3 A) | Reduces power dissipation by ~0.3 W vs. typical 1.3 V diodes at same current, easing thermal management |
| Fast trr (50 ns) | Enables clean commutation in 200–500 kHz SMPS designs without excessive ringing or EMI |
| DO-214AB (SMC) package | Supports high-density automated assembly and delivers 3 A current handling in < 50 mm² board area |
| RoHS & halogen-free | Meets IEC 61249-2-21 and global environmental compliance mandates for commercial/industrial shipments |
Applications
| Switch-Mode Power Supply Output Rectification | Freewheeling Diode in DC-DC Converters |
|---|---|
Use Scenario: Used as secondary-side rectifier in 12 V/3 A isolated flyback or forward converter supplying CPU core rails. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; conducts only when anode > cathode. Use Value: 1.0 V VF and 50 ns trr reduce conduction loss and switching tail energy, improving efficiency by ~1.2% over slower 1N5822-class diodes. | Use Scenario: Placed across inductive windings in synchronous buck controllers to clamp inductive kickback during low-side FET turn-off. IC Role / Device Role / Timing Role: Freewheeling path for inductor current; must recover before next switching cycle to prevent cross-conduction. Use Value: 50 ns trr ensures full recovery within 100 ns dead-time windows common in 300–500 kHz controllers, preventing shoot-through risk. |
| Telecom DC-DC Brick Rectification | Industrial Motor Drive Snubber Network |
Use Scenario: Rectifies 48 V intermediate bus in telecom half-brick DC-DC modules delivering 5 V/10 A to line cards. IC Role / Device Role / Timing Role: High-current output rectifier handling continuous 3 A load with transient surges up to 150 A. Use Value: 150 A IFSM rating accommodates startup surges and short-circuit foldback events without degradation. | Use Scenario: Integrated into RC snubber networks across IGBTs in 24 V BLDC motor drives to absorb turn-off energy. IC Role / Device Role / Timing Role: Clamping diode conducting brief high-di/dt reverse recovery current during IGBT turn-off. Use Value: Low CJ (80 pF) minimizes capacitive loading on gate drivers while enabling fast clamping response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A IF, VF = 1.15 V @ 3 A, trr = 35 ns, DO-214AB | Higher voltage rating suits 48 V bus systems with elevated transients; faster recovery but higher VF | Prefer when system requires >300 V blocking or sub-40 ns trr; verify thermal margin due to higher VF |
| MBR3100CT | Dual common-cathode configuration, 100 V VRRM per diode, VF = 0.85 V @ 3 A, DO-214AB | Offers dual-diode integration for center-tapped or synchronous rectification; lower VF but shared cathode limits topology flexibility | Select when dual-diode function is needed; not suitable as direct single-diode replacement without circuit revision |
Compared with STTH3L06S and MBR3100CT, the HS3B V7G provides optimal balance of 100 V rating, 1.0 V VF, and 50 ns trr for cost-sensitive 12–48 V SMPS outputs where ultra-fast recovery is unnecessary and dual-diode integration is not required.

FAQ
What is the peak repetitive reverse voltage rating of the HS3B V7G?
The HS3B V7G has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2102), where HS3B is explicitly listed with VRRM = 100 V. The HS3B V7G maintains this rating across its full operating temperature range and is intended for use in circuits where reverse voltage does not exceed this limit.
What is the forward voltage drop of the HS3B V7G at 3 A and 25°C?
The forward voltage drop (VF) of the HS3B V7G is 1.0 V at 3 A and TJ = 25°C, as specified in the Electrical Specifications table under "Forward voltage(1)" for HS3B. This value is measured under pulse conditions (PW = 0.3 ms) and represents the typical conduction loss at rated current. The HS3B V7G maintains this VF performance across its qualified temperature range.
Does the HS3B V7G have a defined reverse recovery time, and what is its value?
Yes, the HS3B V7G has a specified reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is documented in the Electrical Specifications table for HS3A–HS3G variants. The HS3B V7G shares this trr specification, confirming its suitability for high-frequency switching applications up to several hundred kHz.
What package type is used for the HS3B V7G, and what are its key mechanical features?
The HS3B V7G uses the DO-214AB (SMC) surface-mount package. Key mechanical features include a low-profile outline, matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 (per J-STD-020), UL 94V-0 flammability-rated molding compound, and cathode polarity indicated by a visible band. These attributes are confirmed in the Mechanical Data and Package Outline Dimensions sections of the HS3A–HS3M datasheet.
Is the HS3B V7G RoHS and halogen-free compliant?
Yes, the HS3B V7G is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. This compliance is explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version K2102). The HS3B V7G meets both environmental directives without requiring special handling or exemptions.
