Product details
Overview
S15JC R7G from Taiwan Semiconductor is a 15A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤1.1 V at 15 A), and 350 A peak surge current capability - deployed in freewheeling paths and switching-mode power supplies for telecom and computing infrastructure.
For engineers reviewing the S15JC R7G datasheet, S15JC R7G pinout, S15JC R7G application, or S15JC R7G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (8 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and DO-214AB mechanical compatibility with automated placement systems.
Technical Context
The S15JC R7G is a single-die, standard recovery rectifier optimized for high-current DC output stages and inductive energy recirculation. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance under 8.3 ms half-sine stress.
Thermally, it delivers 8 °C/W junction-to-lead resistance and 44 °C/W junction-to-ambient resistance in standard PCB mounting, enabling reliable operation up to 150°C junction temperature while maintaining rated 15 A average forward current across -55°C to +150°C storage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in flyback/freewheeling circuits |
| IF(AV) | 15 A - continuous average forward current rating at TC = 110°C; determines heatsink sizing in SMPS output stage |
| IFSM | 350 A - non-repetitive peak surge current (8.3 ms); supports inrush and transient overload resilience |
| VF | ≤1.1 V @ 15 A, 25°C - forward voltage drop directly impacts conduction loss and thermal design in high-efficiency converters |
| RθJL | 8 °C/W - junction-to-lead thermal resistance; enables direct thermal path to PCB copper for compact layout |
| IR | ≤1 µA @ 25°C, ≤250 µA @ 125°C - reverse leakage current affects standby power and high-temperature reliability |
| CJ | 93 pF @ 1 MHz, 4 V - junction capacitance influences high-frequency switching noise and snubber design |
Pinout & Package
Package: DO-214AB (SMC) - surface-mount, molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, cathode indicated by band, weight ≈0.270 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of inductive load or transformer secondary; requires adequate copper area for 15 A conduction |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by band; ties to positive rail in freewheeling configuration; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term stability of reverse leakage and breakdown characteristics under thermal cycling and humidity exposure |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; supports standard SMT assembly without floor-life constraints |
| High IFSM (350 A) | Withstands repeated inrush events in AC/DC front-ends and motor drive snubbers without degradation |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and global environmental directives for industrial and telecom equipment manufacturing |
| DO-214AB mechanical standardization | Ensures compatibility with automated pick-and-place nozzles and reflow profiles across contract manufacturers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1506D (STMicroelectronics) | 600 V VRRM, 15 A IF, VF = 1.7 V typ @ 15 A - higher conduction loss; TO-220AC package | Requires through-hole mounting and larger heatsink; less suitable for high-density SMT designs | Select when legacy through-hole layout or higher surge margin (500 A IFSM) is prioritized over board space |
| VS-15EWH06FN-M3 (Vishay) | 600 V VRRM, 15 A IF, VF = 1.05 V typ @ 15 A - slightly lower VF; DO-214AB package, but MSL Level 2 | Requires moisture bake before reflow; tighter process control needed in high-humidity production environments | Select when marginal VF reduction justifies added assembly complexity and floor-life tracking |
Compared with STTH1506D and VS-15EWH06FN-M3, the S15JC R7G balances low VF (≤1.1 V), industry-standard DO-214AB packaging, J-STD-020 Level 1 handling, and cost-effective SMT scalability - making it optimal for volume telecom and server power supply deployments where assembly simplicity and thermal predictability are critical.

FAQ
What is the maximum junction temperature rating for the S15JC R7G?
The S15JC R7G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows sustained operation in high-ambient environments such as enclosed telecom power modules or industrial inverters. Derating curves confirm 15 A average current is maintainable up to TC = 110°C, and thermal resistance values (RθJL = 8 °C/W) support accurate junction temperature estimation in real-world layouts.
Does the S15JC R7G meet RoHS and halogen-free requirements?
Yes, the S15JC R7G is RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are explicitly stated in the product documentation and verified through TSC's material declarations. The device uses matte tin-plated leads and UL 94V-0 molding compound, supporting environmentally regulated end equipment including EU-based telecom infrastructure and data center hardware.
What is the moisture sensitivity level (MSL) of the S15JC R7G and how does it affect assembly?
The S15JC R7G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This eliminates moisture-related popcorning risk and simplifies SMT line integration - especially valuable in high-volume server PSU and telecom power manufacturing where floor-life tracking adds overhead.
How does the forward voltage (VF) of the S15JC R7G compare to similar 15 A rectifiers?
The S15JC R7G specifies VF ≤ 1.1 V at 15 A and 25°C, measured under standardized pulse conditions (PW = 0.3 ms). This is competitive with leading alternatives - e.g., VS-15EWH06FN-M3 lists 1.05 V typ, while STTH1506D lists 1.7 V typ. The S15JC R7G achieves this performance in DO-214AB with Level 1 MSL, offering a balanced trade-off between conduction loss and manufacturability.
Is the S15JC R7G pin-compatible with other devices in the S15x family?
Yes, all S15x devices - including S15GC, S15JC, S15KC, and S15MC - share identical DO-214AB (SMC) packaging, pinout, and thermal footprint. Only the VRRM rating differs (400 V to 1000 V), allowing direct substitution in existing layouts when voltage margin adjustments are needed - provided thermal and surge requirements remain satisfied for the selected variant.
