Product details

Overview

S4D M6G from Taiwan Semiconductor is a 4A, 200V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤1.15 V at 4 A), high surge capability (100 A @ 8.3 ms), and 150°C max junction temperature. It serves as the primary output rectifier in offline AC/DC adapters and SMPS secondary-side circuits.

For engineers reviewing the S4D M6G datasheet, S4D M6G pinout, S4D M6G application, or S4D M6G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward current rating (4 A), thermal resistance (R_θJL = 13 °C/W), reverse recovery time (1500 ns), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

The S4D M6G is a single-die, standard-recovery silicon rectifier optimized for cost-sensitive, medium-frequency switching power supplies operating below 100 kHz. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect design trade-offs favoring low conduction loss over ultrafast switching.

Thermally, it relies on lead-frame conduction via its DO-214AB (SMC) package with R_θJL = 13 °C/W and R_θJA = 47 °C/W under standard PCB mounting. The cathode band marking and matte tin-plated leads ensure unambiguous polarity and J-STD-002-compliant solderability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH4L06S	4 A, 600 V, ultrafast recovery (t_rr = 50 ns), TO-277 package	Higher V_RRM and faster t_rr suit higher-frequency or higher-voltage designs	Preferred where <100 kHz switching or >200 V blocking is required; not drop-in due to different package and pinout
MBR4200CT	4 A per diode, 200 V, Schottky, dual common-cathode in TO-220AC	Lower V_F (~0.85 V) but limited to ≤125°C junction and no surge rating above 60 A	Used when efficiency at light load matters more than surge robustness; requires through-hole layout change

Compared with STTH4L06S and MBR4200CT, the S4D M6G offers optimal balance of surge ruggedness, thermal capability, and cost for 200 V-class SMPS rectification-without requiring ultrafast timing or Schottky-level conduction loss.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S4D M6G?

The S4D M6G has a V_RRM of 200 V, meaning it reliably blocks up to 200 V of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the Taiwan Semiconductor S4A–S4M datasheet (Version K2102). Exceeding this rating risks avalanche breakdown and permanent damage to the S4D M6G.

Does the S4D M6G have a specified reverse recovery time (t_rr)?

Yes, the S4D M6G has a typical reverse recovery time of 1500 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications table on page 2 of the official datasheet. The 1500 ns t_rr confirms the S4D M6G is a standard-recovery rectifier, not ultrafast.

What package type does the S4D M6G use, and what are its key mechanical features?

The S4D M6G uses the DO-214AB (SMC) surface-mount package. Key mechanical features include UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002, cathode polarity marked by a visible band, and a weight of approximately 0.210 g. These attributes are documented in the Mechanical Data section of the S4A–S4M datasheet.

Is the S4D M6G suitable for lead-free reflow soldering?

Yes, the S4D M6G supports lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device is rated for moisture sensitivity level 1 per J-STD-020-meaning it can be placed directly into reflow without pre-baking. This makes the S4D M6G compatible with standard Pb-free assembly processes used for the S4D M6G.

What is the forward voltage (V_F) specification for the S4D M6G at rated current?

The S4D M6G has a maximum forward voltage of 1.15 V at I_F = 4 A and T_J = 25°C, as specified in the Electrical Specifications table. This V_F value directly determines conduction losses in the application circuit. The S4D M6G's low V_F contributes to improved efficiency in power supplies operating near full load.
