Product details

Overview

S3D V7G from Taiwan Semiconductor is a 200 V, 3 A surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 100 A surge capability, 1.15 V max forward voltage at 3 A, and 10 µA max reverse leakage at 25°C - used in AC/DC front-end rectification for compact switch-mode power supplies.

For engineers reviewing the S3D V7G datasheet, S3D V7G pinout, S3D V7G application, or S3D V7G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (R_θJL = 13 °C/W), junction capacitance (60 pF), reverse recovery time (1500 ns), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

The S3D V7G is a single-die, glass-passivated standard recovery rectifier optimized for high-current, medium-voltage DC output stages. Its 200 V V_RRM, 3 A average forward current, and 100 A non-repetitive surge rating support robust operation under transient load conditions in offline SMPS designs.

Thermal performance is defined by R_θJL = 13 °C/W and R_θJA = 47 °C/W, enabling reliable conduction at T_J up to +150°C. Reverse recovery time of 1500 ns reflects standard recovery behavior suitable for <100 kHz switching topologies without requiring snubbers in many implementations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse blocking voltage; defines safe AC input voltage derating margin for 115/230 VAC systems.
I_F	3 A - Continuous average forward current at T_L = 75°C; determines heatsink-free power handling in compact adapters.
I_FSM	100 A - Peak non-repetitive surge current (8.3 ms sine); supports inrush current tolerance during cold start.
V_F	≤1.15 V @ 3 A, 25°C - Forward drop directly impacts conduction loss and thermal rise in high-duty-cycle operation.
R_θJL	13 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour thermal coupling for passive cooling.
C_J	60 pF @ 4 V, 1 MHz - Junction capacitance affects EMI generation and snubber design in flyback/foward converters.
t_rr	1500 ns - Reverse recovery time influences switching loss and ringing in hard-switched topologies below 100 kHz.

Pinout & Package

DO-214AB (SMC) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Weight: 0.210 g.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L02	200 V, 3 A, 1.1 V V_F, 1200 ns t_rr, TO-220AC package	Through-hole mounting; higher thermal mass but larger footprint and manual assembly required	Select when board-level thermal management favors vertical heatsinking or legacy through-hole production lines
MBR3200CT	200 V, dual 3 A Schottky; 0.85 V V_F, no t_rr, DO-214AB package	Lower conduction loss but limited to ≤125°C operation; unsuitable for 150°C junction environments	Select only if operating T_J stays below 125°C and efficiency gain justifies reduced temperature margin

Compared with STTH3L02 and MBR3200CT, the S3D V7G uniquely balances surface-mount compatibility, 150°C junction rating, and cost-effective standard recovery performance - making it optimal for thermally constrained, high-volume AC/DC adapters where Schottky leakage or through-hole assembly are unacceptable.

FAQ

What is the maximum junction temperature rating for the S3D V7G?

The S3D V7G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows sustained operation in enclosed power supplies where ambient temperatures exceed 70°C. The S3D V7G maintains electrical integrity up to this limit when thermal design respects R_θJL = 13 °C/W and proper PCB copper area is allocated.

Does the S3D V7G have a specified reverse recovery time, and how does it affect circuit design?

Yes, the S3D V7G specifies a reverse recovery time (t_rr) of 1500 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This standard recovery characteristic means the S3D V7G is best suited for switching frequencies below 100 kHz. Designers should include RC snubbers in flyback transformers or account for increased switching loss when using the S3D V7G in quasi-resonant topologies above 65 kHz.

Is the S3D V7G RoHS compliant and halogen-free?

Yes, the S3D V7G is fully RoHS compliant and halogen-free, as confirmed in the "Features" section of the Taiwan Semiconductor S3A–S3M datasheet (Version O2301). This ensures compliance with EU Directive 2011/65/EU and IPC-1752A material declarations, supporting use in consumer, industrial, and medical-adjacent equipment where substance restrictions apply.

What packaging and reel quantity is offered for the S3D V7G?

The S3D V7G is supplied in DO-214AB (SMC) package on 3,000-unit tape-and-reel format, per the "Ordering Information" section of the official datasheet. This configuration supports automated SMT placement at high throughput and aligns with industry-standard feeder compatibility for Fuji, Yamaha, and ASM Pacific platforms.

How does the S3D V7G compare to the S3G V7G in terms of voltage rating and application suitability?

The S3D V7G is rated for 200 V V_RRM, while the S3G V7G is rated for 400 V V_RRM. Both share identical current (3 A), thermal (R_θJL = 13 °C/W), and package (DO-214AB) specifications. Use the S3D V7G in 115 VAC-only or doubler-fed inputs; select the S3G V7G for universal-input (90–264 VAC) designs requiring higher reverse margin, especially in regions with unstable grid voltage.
