Product details

Overview

HS3D V7G from Taiwan Semiconductor is a 200V, 3A surface-mount high-efficiency fast recovery rectifier in DO-214AB (SMC) package, featuring 1.0V max forward voltage at 3A and 50ns reverse recovery time. It serves as primary output rectifier in AC/DC adapters and freewheeling diode in DC/DC buck converters for telecom power supplies.

For engineers reviewing the HS3D V7G datasheet, HS3D V7G pinout, HS3D V7G application, or HS3D V7G equivalent, key selection criteria include V_RRM = 200V, I_F = 3A, t_rr = 50ns, V_F ≤ 1.0V @ 3A, and DO-214AB thermal resistance R_θJA = 60°C/W - all critical for high-frequency switching efficiency and thermal management in compact power designs.

Technical Context

The HS3D V7G uses a glass-passivated single-die silicon junction optimized for fast recovery (t_rr ≤ 50ns) and low conduction loss (V_F ≤ 1.0V @ 3A, 25°C). Its DO-214AB package supports automated placement and delivers 60°C/W junction-to-ambient thermal resistance.

Rated for repetitive peak reverse voltage of 200V and surge current up to 150A (8.3ms half-sine), it operates across -55°C to +150°C junction temperature range with moisture sensitivity level 1 per J-STD-020 - enabling reliable use in reflow-soldered industrial and telecom power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits
I_F	3 A continuous - average forward current rating at 75°C case temperature; sets steady-state power delivery capacity
t_rr	50 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables >100 kHz switching without excessive switching loss
V_F	≤1.0 V @ 3A, 25°C - low conduction drop reduces I²R losses and improves efficiency in 12–48V output rails
R_θJA	60 °C/W - thermal resistance from junction to ambient in standard PCB layout; determines heatsinking requirement for 3A operation
I_FSM	150 A - peak surge rating for 8.3ms half-sine; withstands inrush and transient overloads in SMPS startup

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-efficiency rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L02	V_RRM = 200V, I_F = 3A, t_rr = 35ns, V_F = 0.95V @ 3A - faster recovery but tighter V_F tolerance	Better suited for >300 kHz designs where Q_rr dominates loss; less margin for thermal derating at 100°C	Select STTH3L02 when minimizing reverse recovery loss is critical and board-level thermal design supports <100°C junction temp
MBR320	V_RRM = 200V, I_F = 3A, Schottky architecture, V_F = 0.52V @ 3A, no recovery time - but I_R = 200µA @ 125°C	Lower conduction loss ideal for 5–12V outputs; unsuitable for >85°C ambient due to leakage-driven inefficiency	Choose MBR320 for low-voltage, low-temperature applications where leakage-induced standby loss must be minimized

Compared with STTH3L02 and MBR320, the HS3D V7G delivers balanced performance: its 50ns t_rr and 1.0V V_F offer optimal trade-off between switching and conduction loss across 100–250 kHz telecom power stages, while its 150°C T_JMAX and robust leakage (250µA @ 125°C) ensure stable operation in thermally constrained enclosures.

FAQ

What is the maximum junction temperature rating for HS3D V7G?

The HS3D V7G has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet K2102. This rating allows continuous operation at full 3A current in ambient temperatures up to 75°C when mounted on a standard 1-inch² copper pad. Exceeding this limit risks permanent degradation of the glass-passivated junction in the HS3D V7G.

Does HS3D V7G have a halogen-free construction?

Yes, the HS3D V7G is halogen-free in accordance with IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor HS3A–HS3M datasheet (Version K2102). The molding compound and plating materials contain no bromine, chlorine, or other regulated halogens, supporting compliance for export to EU, Japan, and other regulated markets where HS3D V7G is deployed.

What is the reverse recovery time (t_rr) specification for HS3D V7G?

The HS3D V7G has a maximum reverse recovery time (t_rr) of 50 ns, measured under conditions I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A, per the Electrical Specifications table in the K2102 datasheet. This value is confirmed for all HS3A–HS3G variants, including HS3D V7G, and directly impacts switching loss in 100–500 kHz power topologies where HS3D V7G is commonly applied.

Is HS3D V7G compatible with lead-free reflow soldering processes?

Yes, the HS3D V7G is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated Class 1 per J-STD-020 - meaning it can be placed directly from dry pack without baking, even for peak reflow temperatures up to 260°C. This ensures robust intermetallic formation and joint integrity in HS3D V7G assembly.

What does the 'V7G' suffix indicate in HS3D V7G?

The 'V7G' suffix in HS3D V7G denotes Taiwan Semiconductor's internal date code and factory marking: 'V7' corresponds to week 7 of 2023, and 'G' identifies the fabrication facility. This marking appears on the device body per the "Marking Diagram" in the K2102 datasheet and does not affect electrical specifications - all HS3D units, including HS3D V7G, share identical V_RRM = 200V, I_F = 3A, and t_rr = 50ns performance.
