Product details
Overview
S12JC R7G from Taiwan Semiconductor is a 12A, 600V glass-passivated surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage drop (≤1.1 V at 12 A), high surge capability (300 A IFSM), and J-STD-020 Level 1 moisture sensitivity - deployed in AC/DC front-end stages of industrial SMPS and LED drivers.
For engineers reviewing the S12JC R7G datasheet, S12JC R7G pinout, S12JC R7G application, or S12JC R7G equivalent, key selection criteria include verified 600 V repetitive peak reverse voltage, thermal resistance (RθJL = 9 °C/W), RoHS/halogen-free compliance, and DO-214AB mechanical compatibility with automated SMT lines.
Technical Context
This single-die standard recovery rectifier operates with junction temperature range –55 °C to +150 °C and supports continuous 12 A average forward current. Its 300 A non-repetitive surge rating (8.3 ms sine wave) enables robust input rectification under line transients.
Electrical behavior is characterized by ≤1 µA reverse leakage at 25 °C and ≤250 µA at 125 °C, plus 78 pF junction capacitance at 1 MHz and 4 V reverse bias - parameters critical for EMI filtering and switching loss estimation in high-frequency converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe AC input voltage derating margin in bridge or single-phase rectifier designs |
| IF | 12 A - continuous average forward current at TA = 75 °C; determines heatsink sizing in convection-cooled power supplies |
| IFSM | 300 A - peak non-repetitive surge current (8.3 ms); validates immunity to cold-start inrush and lightning-induced surges |
| VF | ≤1.1 V @ 12 A, 25 °C - forward voltage drop directly impacts conduction loss and thermal rise in high-current rectification paths |
| RθJL | 9 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour thermal design without external heatsink in many 12 A applications |
| CJ | 78 pF @ 1 MHz, 4 V - junction capacitance affects high-frequency reverse recovery noise and snubber sizing |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode-indicating band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point during forward conduction | Connected to AC line or transformer secondary; requires adequate trace width for 12 A RMS current |
| Cathode (Lead 2) | Output current exit point during forward conduction | Connected to bulk capacitor or DC bus; polarity marking ensures correct orientation in full-wave layouts |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments |
| J-STD-020 Level 1 moisture sensitivity | Enables direct placement without baking; reduces manufacturing overhead in high-volume SMT lines |
| UL 94V-0 molding compound | Meets flame-retardancy requirements for end equipment safety certifications (e.g., UL 62368-1) |
| RoHS and halogen-free compliance | Supports global environmental compliance (EU RoHS, JEITA-MITI) and avoids corrosive outgassing in sealed enclosures |
Applications
| Industrial SMPS Front-End | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 230 VAC mains input in 100–300 W open-frame power supplies for factory automation controllers. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC to pulsating DC before PFC stage. Use Value: 600 V VRRM provides 2× safety margin over 230 VAC peak (325 V), while 300 A IFSM withstands repeated cold-start surges. | Use Scenario: Input rectification in constant-current LED drivers for street lighting operating in outdoor ambient (–40 °C to +85 °C). IC Role / Device Role / Timing Role: Single-phase bridge leg component delivering stable DC bus for buck converter regulation. Use Value: –55 °C to +150 °C TJ rating ensures operation across full industrial temperature range without derating. |
| AC/DC Adapter Secondary | DC-DC Converter Input Protection |
Use Scenario: Output rectification in universal-input (90–264 VAC) 65 W laptop adapters with high-efficiency topology. IC Role / Device Role / Timing Role: High-current output diode in synchronous or quasi-resonant flyback secondary side. Use Value: ≤1.1 V VF minimizes conduction loss at 12 A load, improving efficiency above 90% at full load. | Use Scenario: Reverse-polarity and overvoltage protection at input of isolated 48 V to 12 V DC-DC modules in telecom shelf systems. IC Role / Device Role / Timing Role: Standby-blocking diode preventing backfeed from downstream capacitors during hot-swap events. Use Value: 250 µA max IR at 125 °C ensures minimal standby leakage, preserving hold-up time during brownouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1206D (STMicroelectronics) | 600 V VRRM, 12 A IF, but faster recovery (trr = 65 ns vs. standard recovery >1 µs); higher VF (1.7 V) | Better suited for high-frequency PFC where reverse recovery loss dominates; less optimal for cost-sensitive SMPS with <100 kHz switching | Select S12JC R7G when conduction loss and BOM cost are prioritized over ultra-fast switching noise control |
| GBU12J (ON Semiconductor) | Same DO-214AB package and 600 V rating, but GBU-series uses molded case with different leadframe geometry; slightly higher RθJA (50 °C/W) | Compatible footprint but requires revalidation of thermal performance in thermally constrained layouts | Choose S12JC R7G when lower junction-to-ambient thermal resistance (44 °C/W) is required for natural-convection cooling |
Compared with STTH1206D and GBU12J, the S12JC R7G delivers superior thermal efficiency (RθJL = 9 °C/W) and lower forward voltage, making it optimal for space-constrained, convection-cooled industrial power supplies where conduction loss dominates system efficiency.

FAQ
What is the maximum junction temperature rating for the S12JC R7G?
The S12JC R7G has a maximum junction temperature (TJ) rating of +150 °C, with operational range from –55 °C to +150 °C. This allows reliable use in enclosed industrial enclosures without forced airflow. The S12JC R7G's thermal resistance values (RθJL = 9 °C/W, RθJA = 44 °C/W) enable accurate junction temperature prediction under real-world PCB layout conditions.
Does the S12JC R7G meet RoHS and halogen-free requirements?
Yes, the S12JC R7G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms this in the official datasheet revision D2102. These compliance attributes are verified for the S12JC R7G and documented in its material declaration - essential for export to EU, Japan, and other regulated markets.
What does the 'R7G' suffix indicate in S12JC R7G?
The 'R7G' suffix in S12JC R7G denotes tape-and-reel packaging (R7 = 3,000 pcs/reel) and green molding compound (G). It does not affect electrical specifications. All S12JC variants - including S12JC R7G - share identical absolute maximum ratings, electrical characteristics, and DO-214AB mechanical dimensions per the D2102 datasheet.
Can the S12JC R7G replace S12KC or S12MC in a design?
No - the S12JC R7G is rated for 600 V VRRM, whereas S12KC and S12MC are rated for 800 V and 1000 V respectively. Substituting S12JC R7G in a circuit designed for higher reverse voltage risks premature breakdown. Always verify reverse voltage stress margins before interchanging S12GC–S12MC family members; the S12JC R7G is only suitable where 600 V blocking is sufficient.
Is the S12JC R7G suitable for automated SMT assembly?
Yes, the S12JC R7G is optimized for automated placement: it carries J-STD-020 Level 1 moisture sensitivity (no bake required), matte tin-plated leads compliant with J-STD-002, and DO-214AB (SMC) package geometry validated for pick-and-place accuracy. These features ensure high first-pass yield in high-volume SMT lines using the S12JC R7G.
