Product details

Overview

S3J R7G from Taiwan Semiconductor is a 3A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15V max forward voltage at 3A, 100A surge capability, and 150°C max junction temperature - used in AC/DC front-end rectification for industrial SMPS and lighting ballasts.

For engineers reviewing the S3J R7G datasheet, S3J R7G pinout, S3J R7G application, or S3J R7G equivalent, key selection criteria include repetitive peak reverse voltage (600V), thermal resistance (13°C/W junction-to-lead), reverse recovery time (1500ns), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance.

Technical Context

This single-die standard recovery rectifier operates with a 600V V_RRM, supports continuous 3A forward current, and delivers 100A non-repetitive surge current (8.3ms half-sine). Its 1500ns reverse recovery time and 60pF junction capacitance reflect trade-offs favoring cost-effective general-purpose rectification over ultra-fast switching.

Thermal performance is defined by R_θJL = 13°C/W and R_θJA = 47°C/W, enabling reliable operation up to 150°C junction temperature. The device uses glass-passivated junctions and matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum repetitive reverse blocking voltage; defines safe operating range in bridge or single-phase rectifier topologies
I_F	3 A - continuous average forward current; determines heatsink sizing and conduction loss in steady-state operation
I_FSM	100 A - peak non-repetitive surge current (8.3ms); enables robustness against line transients and inrush events
V_F	≤1.15 V @ 3A, 25°C - forward voltage drop; directly impacts conduction loss and thermal design in high-current paths
t_rr	1500 ns - reverse recovery time; influences switching losses and EMI in higher-frequency converters (e.g., 50–100 kHz SMPS)
R_θJL	13 °C/W - junction-to-lead thermal resistance; critical for estimating die temperature rise under PCB copper pad cooling
MSL	Level 1 - no floor life limitation; allows unlimited exposure to ambient conditions before reflow soldering

Pinout & Package

DO-214AB (SMC) surface-mount package with cathode-indicated band; molded plastic body meets UL 94V-0; matte tin-plated leads; weight ≈0.210g.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600V V_RRM, 3A I_F, 1.1V V_F, 1200ns t_rr, TO-277 package	Lower V_F and faster t_rr, but TO-277 requires different footprint and has higher R_θJA	Preferred where lower conduction loss and EMI matter more than layout reuse
ON Semi MUR360	600V V_RRM, 3A I_F, 1.25V V_F, 75ns t_rr, DO-201AD package	Ultrafast recovery enables >100kHz operation, but higher V_F increases loss; axial leaded form factor	Used when fast switching dominates over thermal efficiency and SMT is not required

Compared with STTH3L06S and MUR360, the S3J R7G offers optimal balance of cost, thermal performance (R_θJL = 13°C/W), and SMT manufacturability in DO-214AB - making it preferred for high-volume, space-constrained industrial rectifiers where 1500ns t_rr is acceptable.

FAQ

What is the maximum junction temperature rating for the S3J R7G?

The S3J R7G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial enclosures. Derating curves confirm usable current capacity down to 1.5A at 125°C ambient with adequate PCB copper area. The S3J R7G must be mounted on ≥1 cm² of 2-oz copper to sustain rated current at elevated temperatures.

Does the S3J R7G meet RoHS and halogen-free requirements?

Yes, the S3J R7G is fully RoHS compliant and halogen-free per Taiwan Semiconductor's O2301 specification. The molding compound contains no brominated flame retardants, and the matte tin plating on leads satisfies EU Directive 2011/65/EU and JEDEC JS709E. Certificate of Compliance is available upon request for S3J R7G shipments, covering all homogeneous materials in the DO-214AB package.

What is the reverse recovery time (t_rr) of the S3J R7G, and how does it affect circuit design?

The S3J R7G has a typical reverse recovery time (t_rr) of 1500 ns under IF = 0.5A, IR = 1.0A, and Irr = 0.25A test conditions. This places it in the standard recovery category, suitable for line-frequency and 50–100 kHz SMPS designs. In circuits above 100 kHz, designers should evaluate switching loss and EMI impact; the S3J R7G may require snubbers or gate drive optimization where fast recovery is critical.

Is the S3J R7G pin-compatible with other devices in the S3x family?

Yes, all S3A–S3M devices share identical DO-214AB (SMC) package dimensions, pinout, and thermal characteristics - including the S3J R7G. Anode and cathode terminals are fixed per JEDEC outline; only V_RRM and related parameters differ. This allows direct substitution within the same board layout when voltage rating changes are needed, provided thermal and surge margins remain sufficient for the new application.

What packaging and reel specifications apply to the S3J R7G?

The S3J R7G is supplied in tape-and-reel format: 3,000 units per 12mm-wide embossed carrier tape, complying with EIA-481-D standards. Reels are 330mm diameter with 13-inch core, labeled with Taiwan Semiconductor part marking "S3J" and date code "R7G". Moisture sensitivity level is MSL 1, so no dry pack or baking is required prior to SMT placement - simplifying logistics and line-side handling for the S3J R7G.
