Product details

Overview

HS3G V7G from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 3 A average forward current, surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.3 V max forward voltage at 3 A and 50 ns max reverse recovery time-used for high-frequency freewheeling and output rectification in switching-mode power supplies.

For engineers reviewing the HS3G V7G datasheet, HS3G V7G pinout, HS3G V7G application, or HS3G V7G equivalent, key selection criteria include its 400 V V_RRM, 150 A I_FSM, 60 °C/W R_θJA, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance.

Technical Context

This device is a single-die, glass-passivated, standard recovery silicon rectifier optimized for high-efficiency DC output stages in SMPS and telecom converters. Its 50 ns trr and low VF support reduced conduction and switching losses at frequencies up to several hundred kHz.

The DO-214AB (SMC) package enables automated placement and provides robust thermal dissipation with 60 °C/W junction-to-ambient resistance. Cathode polarity is marked by a visible band, and terminals are matte tin-plated per J-STD-002 solderability standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum non-repetitive reverse blocking voltage; defines safe operating range in bridge or flyback output rectifiers
I_F	3 A - continuous average forward current at T_A = 75 °C; sets baseline conduction capability for 24–48 V output rails
I_FSM	150 A - peak surge current (8.3 ms half-sine); supports inrush and transient overload tolerance
V_F @ 3 A	≤1.3 V - forward voltage drop at rated current; directly impacts conduction loss and thermal rise in high-current paths
t_rr	≤50 ns - reverse recovery time; enables stable operation in 100–500 kHz switching topologies without excessive ringing
R_θJA	60 °C/W - thermal resistance from junction to ambient; determines heatsinking requirements on standard FR-4 PCBs

Pinout & Package

DO-214AB (SMC) surface-mount package with cathode-indicated band; 2-terminal configuration (anode and cathode), matte tin-plated leads, UL 94V-0 molding compound, and 0.210 g typical weight.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to input/switching node side of rectifier path; must withstand full surge current and reverse voltage stress
Cathode	Forward current exit point / polarity reference	Marked by visible band; ties to output filter capacitor or load return; defines direction of unidirectional conduction

Key Features

Feature	Design Value
Glass passivated junction	Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments
Moisture sensitivity level 1	Allows unlimited floor life before reflow; eliminates bake preconditioning and simplifies SMT line integration
JESD201 Class 2 whisker resistance	Prevents tin whisker growth under mechanical stress and temperature cycling-critical for automotive and telecom infrastructure
Halogen-free per IEC 61249-2-21	Meets RoHS and environmental compliance mandates for export to EU, Japan, and Korea without material declaration overhead

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-3EJH04-M3/5AT	Same DO-214AB package, 400 V V_RRM, but 1.5 V V_F @ 3 A and 75 ns t_rr	Higher conduction loss and slower recovery limit use in >250 kHz designs	Preferred where cost sensitivity outweighs efficiency targets and layout space allows minor thermal margin increase
ON Semiconductor MUR340G	Ultrafast recovery (35 ns), same 400 V rating, but TO-220AC package-not surface-mount compatible	Requires through-hole assembly and larger board area; unsuitable for high-density SMT-only production	Select only when legacy TO-220 footprint reuse or higher surge robustness (200 A I_FSM) is prioritized over automation and size

Compared with VS-3EJH04-M3/5AT and MUR340G, the HS3G V7G delivers superior high-frequency efficiency via lower V_F and faster t_rr, while maintaining full SMT compatibility and JEDEC-compliant moisture handling-making it optimal for next-gen telecom and server power modules.

FAQ

What is the maximum junction temperature rating for HS3G V7G?

The HS3G V7G has a maximum junction temperature (T_J) rating of +150 °C, consistent across the entire HS3x series. This allows reliable operation in thermally constrained environments such as sealed telecom enclosures or high-power density server VRMs, provided the thermal design maintains junction temperature below this limit under worst-case load and ambient conditions. The HS3G V7G's 60 °C/W R_θJA enables direct estimation of allowable power dissipation on standard PCB layouts.

Does HS3G V7G meet RoHS and halogen-free requirements?

Yes, the HS3G V7G is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms both certifications apply to this specific part number and its DO-214AB (SMC) packaging. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to J-STD-002 standards-ensuring full regulatory alignment for export to EU, Japan, and Korea without additional material declarations.

What does the "V7G" suffix indicate in HS3G V7G?

The "V7G" suffix in HS3G V7G denotes Taiwan Semiconductor's internal revision and green compound coding: "V7" indicates version K2102 per the official datasheet revision history, and "G" specifies halogen-free green molding compound. This marking aligns with TSC's standardized ordering nomenclature and appears on the device body as part of the full marking code, confirming compliance with environmental and manufacturing specifications stated in the HS3x datasheet.

Can HS3G V7G replace HS3F or HS3J in an existing design?

HS3G V7G can replace HS3F (300 V) if the circuit's peak reverse voltage remains ≤400 V, but not HS3J (600 V) due to insufficient V_RRM margin. Forward voltage increases from 1.0 V (HS3F) to 1.3 V (HS3G), raising conduction loss slightly; reverse recovery time remains identical at ≤50 ns. Thermal and package compatibility is maintained-same DO-214AB footprint and soldering profile-so no PCB changes are required for HS3F substitution.

Is HS3G V7G suitable for use in automotive applications?

The HS3G V7G is not qualified to AEC-Q101 or automotive-grade reliability standards, and Taiwan Semiconductor explicitly states these devices are not designed for medical, life-saving, or life-sustaining applications-including automotive safety-critical systems. While its 150 °C T_J and JESD201 Class 2 whisker resistance support harsh environments, formal automotive qualification requires additional testing and documentation not provided for HS3G V7G.
