Product details

Overview

S4J M6G from Taiwan Semiconductor is a 4A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass passivated junction, low forward voltage drop (≤1.15 V at 4 A), and high surge current capability (100 A, 8.3 ms). It serves as a primary AC/DC conversion element in offline switch-mode power supplies.

For engineers reviewing the S4J M6G datasheet, S4J M6G pinout, S4J M6G application, or S4J M6G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJL = 13 °C/W), junction temperature range (–55 to +150 °C), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

The S4J M6G is a single-die, standard recovery rectifier with 1500 ns reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions. Its 600 V V_RRM rating targets mid-voltage industrial and consumer offline converters.

Thermal performance is defined by R_θJL = 13 °C/W and R_θJA = 47 °C/W, supporting continuous 4 A conduction at ambient temperatures up to 75 °C on standard FR-4 PCBs with recommended pad layout per DO-214AB outline. Polarity is marked by cathode band.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification for 230 VAC mains with ≥2× safety margin
I_F	4 A continuous - sustains full-load output in 60–100 W SMPS designs
I_FSM	100 A (8.3 ms) - withstands cold-start inrush without failure
V_F	≤1.15 V @ 4 A, 25°C - limits conduction loss to ≤4.6 W at full load
T_J max	+150°C - enables operation in enclosed, thermally constrained enclosures
R_θJL	13 °C/W - allows direct heat transfer to copper pour or heatsink via cathode lead
trr	1500 ns - suitable for <100 kHz switching topologies; not for high-frequency ZVS/ZCS

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH4L06S	V_RRM = 600 V, I_F = 4 A, trr = 75 ns, VF = 1.7 V @ 4 A	Ultrafast recovery enables higher-frequency topologies; higher V_F increases conduction loss	Prefer STTH4L06S where EMI reduction or >100 kHz operation is required; S4J M6G preferred for cost-sensitive, thermally constrained 50–100 kHz designs
MBR460	V_RRM = 60 V, I_F = 4 A, VF = 0.75 V @ 4 A, Schottky construction	Lower V_F but insufficient for 230 VAC input; limited to low-voltage DC-DC inputs	MBR460 is unsuitable for line rectification; only applicable in secondary-side 48 V or lower DC inputs

Compared with STTH4L06S and MBR460, the S4J M6G delivers optimal balance of 600 V robustness, 1.15 V forward drop, and cost-effective standard recovery performance for mainstream offline SMPS - without requiring ultrafast timing or sacrificing voltage rating.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S4J M6G?

The S4J M6G has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, as specified in the absolute maximum ratings table of the Taiwan Semiconductor datasheet (Version K2102). This rating ensures reliable operation when rectifying 230 VAC mains with appropriate safety margins and transient suppression. The S4J M6G is part of the S4A–S4M family, where the letter "J" explicitly denotes the 600 V variant.

Does the S4J M6G have a RoHS-compliant and halogen-free construction?

Yes, the S4J M6G is RoHS compliant and halogen-free according to IEC 61249-2-21, as confirmed in the FEATURES section of the official Taiwan Semiconductor datasheet. Its molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads comply with J-STD-002 solderability standards. These attributes make the S4J M6G suitable for environmentally regulated markets including the EU and North America.

What is the thermal resistance from junction to lead (R_θJL) for the S4J M6G?

The junction-to-lead thermal resistance (R_θJL) of the S4J M6G is 13 °C/W, per the THERMAL PERFORMANCE table in the Taiwan Semiconductor datasheet. This value reflects efficient heat conduction from the die through the cathode lead to the PCB copper pour, enabling sustained 4 A operation without external heatsinking when using the recommended DO-214AB pad layout.

Is the S4J M6G suitable for high-frequency switching applications above 100 kHz?

No, the S4J M6G is not optimized for high-frequency switching above 100 kHz due to its 1500 ns reverse recovery time (trr), which is characteristic of standard recovery rectifiers. It is best suited for 50–100 kHz offline SMPS topologies. For frequencies beyond 100 kHz, consider ultrafast alternatives like STTH4L06S (trr = 75 ns), though with higher forward voltage. The S4J M6G datasheet does not specify performance above 100 kHz.

What marking code appears on the S4J M6G device body?

The S4J M6G is marked with "S4J" on the device body, as shown in the MARKING DIAGRAM section of the Taiwan Semiconductor datasheet. The "M6G" suffix in the ordering code corresponds to packaging and date code information (e.g., tape-and-reel, green compound, YW date code), not the visible top-side marking. The visible marking is strictly "S4J", confirming its 600 V rating within the S4A–S4M family.
