Product details
Overview
S3M V7G from Taiwan Semiconductor is a 3A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15V max forward voltage at 3A/25°C, 100A non-repetitive surge current, and 150°C maximum junction temperature - deployed in high-voltage AC/DC front-end stages of industrial SMPS and LED drivers.
For engineers reviewing the S3M V7G datasheet, S3M V7G pinout, S3M V7G application, or S3M V7G equivalent, key selection criteria include repetitive peak reverse voltage (1000V), thermal resistance (RθJL = 13°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for automated SMT assembly in high-reliability power converters.
Technical Context
This device is a single-die, glass-passivated standard recovery rectifier optimized for line-frequency and low-frequency switching applications up to 60 Hz. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs favoring low conduction loss over fast switching.
Designed for operation across -55°C to +150°C junction range, it delivers stable 3A average forward current with derating above 75°C ambient and supports 8.3 ms half-sine surge peaks up to 100A - suitable for input rectification where EMI filtering and thermal management are prioritized over ultra-fast recovery.
Key Specifications

| IF | 3 A - Continuous average forward current rating at TL = 75°C with proper PCB copper area |
| IFSM | 100 A - Handles 8.3 ms surge events (e.g., cold-start inrush) without permanent damage |
| VF | ≤1.15 V @ 3A/25°C - Minimizes conduction loss and self-heating in high-current rectifier bridges |
| TJ max | +150 °C - Enables operation in enclosed, high-ambient industrial enclosures with limited airflow |
| RθJL | 13 °C/W - Allows direct thermal path to PCB copper pour for efficient heat dissipation without heatsink |
| CJ | 60 pF @ 1 MHz / 4 V - Limits high-frequency noise coupling in EMI-sensitive offline supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10 | Same 3A/1000V rating, but TO-277 package (smaller footprint, higher RθJA = 60°C/W) | Preferred where board space is constrained but thermal budget allows higher ambient rise | Select VS-3EWH10 only if PCB layout permits tighter pad spacing and thermal simulation confirms safe TJ |
| ON Semiconductor MUR3100CT | Ultrafast recovery (trr = 75 ns), dual common-cathode configuration, TO-220AC package | Used in higher-frequency PFC or resonant converters requiring faster switching and lower EMI | Choose MUR3100CT when trr < 200 ns is required; not drop-in due to different package and pinout |
Compared with VS-3EWH10 and MUR3100CT, the S3M V7G offers superior thermal transfer via DO-214AB's low RθJL, lower cost in tape-and-reel volume, and simpler single-diode integration - making it optimal for cost-sensitive, thermally demanding, low-frequency rectification where fast recovery is unnecessary.

FAQ
What is the maximum junction temperature rating for the S3M V7G?
The S3M V7G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial enclosures where ambient temperatures exceed 85°C, provided PCB thermal design maintains junction temperature below this limit. Derating curves in the S3M V7G datasheet specify allowable forward current reduction above 75°C lead temperature.
Does the S3M V7G meet RoHS and halogen-free requirements?
Yes, the S3M V7G is RoHS compliant and halogen-free, as confirmed in the "Features" section of the official Taiwan Semiconductor documentation. It satisfies EU Directive 2011/65/EU and meets IPC-1752A material declaration standards, making it suitable for export-controlled and environmentally regulated end products such as commercial lighting and industrial automation equipment.
What is the reverse recovery time (trr) of the S3M V7G and how does it affect circuit design?
The S3M V7G has a reverse recovery time (trr) of 1500 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This relatively slow recovery indicates it is intended for line-frequency or low-frequency (<10 kHz) rectification, not high-frequency switching. Designers should avoid using the S3M V7G in PFC or resonant topologies where trr < 500 ns is required to minimize switching losses and EMI.
Is the S3M V7G suitable for use in a full-wave bridge configuration?
Yes, the S3M V7G is a single-die, single-diode rectifier rated for 3 A average forward current and 1000 V peak reverse voltage, making it appropriate for discrete full-wave bridge implementations - for example, four S3M V7G devices mounted on a thermally enhanced PCB. Its DO-214AB package supports automated placement and its 13°C/W junction-to-lead thermal resistance enables effective heat spreading without additional heatsinking in properly designed layouts.
What packaging and reel quantity is offered for the S3M V7G?
The S3M V7G is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, as specified in the "Ordering Information" section of the Taiwan Semiconductor datasheet. The reel complies with EIA-481-D standards and includes MSL Level 1 handling instructions - meaning no dry-pack or baking is required prior to surface-mount reflow processing.
