Product details
Overview
S1J R3G from Taiwan Semiconductor is a 1 A, 600 V surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, 1.1 V max forward voltage at 1 A, 1 µA max reverse leakage at 25°C, and 1500 ns reverse recovery time - used in DC-DC converters and snubber circuits.
For engineers reviewing the S1J R3G datasheet, S1J R3G pinout, S1J R3G application, or S1J R3G equivalent, key selection criteria include peak repetitive reverse voltage (600 V), surge current capability (40 A), thermal resistance (27 °C/W junction-to-lead), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This standard recovery rectifier employs a single-die silicon PN junction with glass passivation for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its 1500 ns reverse recovery time and 12 pF junction capacitance at 4 V bias reflect optimized trade-offs between switching speed and low-loss conduction.
The device operates across -55°C to +175°C junction temperature range, with thermal resistance of 27 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), enabling stable performance in compact, high-density PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in 600 V-rated power rails |
| IF | 1 A continuous - average forward current rating; supports sustained 1 A load in thermally managed designs |
| VF (max) | 1.1 V @ 1 A, 25°C - forward drop directly impacts conduction loss and thermal budget in rectification stages |
| IR (max) | 1 µA @ 25°C - low leakage ensures minimal standby power loss in high-impedance bias networks |
| trr | 1500 ns - reverse recovery time affects switching losses and EMI in medium-frequency SMPS (≤100 kHz) |
| RθJL | 27 °C/W - enables direct thermal path to PCB copper; critical for derating above 75°C ambient |
| Package | DO-214AC (SMA) - industry-standard surface-mount outline with cathode band polarity marking |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case meeting UL 94V-0, matte tin-plated leads solderable per J-STD-002, cathode indicated by band, weight ≈ 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or filter capacitor positive; blocks 600 V reverse |
Key Features
| Feature | Design Value |
|---|---|

| 175°C max junction temperature | Enables operation in high-ambient environments (e.g., enclosed power supplies, LED drivers) |
| 40 A non-repetitive surge rating | Withstands inrush currents during cold-start or transient overloads without failure |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V at ≤1 A. IC Role / Device Role / Timing Role: Unidirectional current steering and AC-to-DC conversion; not timing-critical but must sustain 600 V reverse during MOSFET off-time. Use Value: Low VF minimizes conduction loss; 1500 ns trr avoids excessive switching loss at ≤100 kHz switching frequencies. | Use Scenario: Clamp voltage spikes across switching transistors in motor drives or SMPS primary side. IC Role / Device Role / Timing Role: Transient energy absorption via controlled reverse conduction; acts as passive clamping element. Use Value: 600 V VRRM safely handles reflected spikes; 40 A IFSM absorbs short-duration surge energy without degradation. |
| Lighting Driver | Switching Inverter |
Use Scenario: Input rectification stage in constant-current LED drivers for commercial lighting fixtures. IC Role / Device Role / Timing Role: AC line rectification feeding bulk capacitor; operates in continuous conduction mode. Use Value: 175°C TJ max allows reliable operation near heat-generating LED arrays; RoHS/halogen-free meets lighting safety standards. | Use Scenario: Output rectification in low-power inverters converting 12/24 V DC to 110/220 V AC square-wave output. IC Role / Device Role / Timing Role: Full-wave or half-wave DC reconstruction; must block reverse voltage during polarity reversal. Use Value: 600 V VRRM exceeds peak AC output voltage; DO-214AC footprint simplifies automated assembly on double-sided boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | Ultrafast recovery (75 ns), higher VF (1.3 V), same 1 A/600 V rating, DO-41 through-hole | Requires PCB layout change; better for >100 kHz switching but less efficient at low frequency | Select when faster recovery is needed and through-hole mounting is acceptable |
| Vishay VS-1N4007-M3/54 | General-purpose 1 A/1000 V, 30 µA IR @ 25°C, 2 µs trr, DO-41 | Higher leakage and slower recovery; lower cost but reduced efficiency in regulated supplies | Choose for non-critical, low-frequency, cost-sensitive applications where 600 V margin is sufficient |
Compared with MUR160 and VS-1N4007-M3/54, the S1J R3G offers optimal balance of low VF (1.1 V), moderate trr (1500 ns), surface-mount DO-214AC packaging, and J-STD-020 Level 1 handling - making it preferred for automated, high-volume, mid-frequency industrial power supplies.

FAQ
What is the maximum junction temperature rating for the S1J R3G?
The S1J R3G has a maximum junction temperature (TJ) rating of +175°C, allowing operation in high-ambient environments such as enclosed power supplies or LED driver modules. This rating is validated under specified thermal conditions and must be maintained using appropriate PCB copper area and airflow. Derating curves in the S1J R3G datasheet define allowable current versus ambient temperature to ensure TJ remains within limit.
Is the S1J R3G RoHS and halogen-free compliant?
Yes, the S1J R3G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms this compliance in the official S1A–S1M datasheet (Version S2102), and the device carries no restricted substances above threshold limits. This makes the S1J R3G suitable for export to EU, China, and other regulated markets requiring environmental conformity.
What does the "R3G" suffix indicate in S1J R3G?
The "R3G" suffix in S1J R3G denotes Taiwan Semiconductor's internal packaging and environmental code: "R" indicates tape-and-reel packaging (7,500 units per reel), "3" specifies green molding compound (halogen-free), and "G" identifies the manufacturing site and date code format. It does not alter electrical specifications - all S1J devices share identical VRRM = 600 V, IF = 1 A, and trr = 1500 ns parameters.
Can the S1J R3G replace a 1N4007 in a new design?
The S1J R3G can functionally replace a 1N4007 in many applications due to its higher VRRM (600 V vs. 1000 V) and superior thermal performance, but it is not a direct drop-in replacement because of differing packages: S1J R3G uses DO-214AC (SMA), while 1N4007 uses DO-41. Layout redesign is required. Also, S1J R3G has lower IR (1 µA vs. ~5 µA) and faster trr (1500 ns vs. ~2 µs), improving efficiency in switching circuits.
What is the reverse recovery time (trr) specification for the S1J R3G?
The S1J R3G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official Taiwan Semiconductor datasheet. This value reflects its standard recovery behavior - suitable for line-frequency and medium-frequency (<100 kHz) switching applications but not ultrafast topologies. The trr contributes directly to switching loss and EMI generation in SMPS designs using the S1J R3G.
