Taiwan Semiconductor Corporation S10JC

Overview

S10JC from Taiwan Semiconductor is a 10A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 1.1V max forward voltage at 10A/25°C, and 250A peak surge capability - used in AC/DC front-end rectification for industrial SMPS and LED drivers.

For engineers reviewing the S10JC datasheet, S10JC pinout, S10JC application, or S10JC equivalent, key selection criteria include verified VRRM = 600V, IFSM = 250A, R_θJL = 10°C/W thermal resistance, and DO-214AB mechanical compatibility with automated SMT placement.

Technical Context

The S10JC is a single-die, standard recovery rectifier optimized for high-efficiency switching power supplies operating at 50–100 kHz. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <250 µA @ 125°C) and robust surge tolerance under repetitive 8.3 ms half-sine stress.

Thermally, it delivers R_θJL = 10°C/W to lead and R_θJA = 47°C/W in free air, enabling 10A continuous conduction without forced cooling when mounted on ≥1 in² 2-oz copper. Polarity is marked by cathode band per JEDEC DO-214AB outline.

Compared with VS-10EWH06-M3 and MUR1060CT, the S10JC offers lower VF and identical DO-214AB SMT compatibility, making it optimal for high-density, thermally constrained board layouts where minimizing conduction loss and avoiding manual assembly are priorities.

Availability

S10JC is available at Aetrix Electronics and suitable for industrial switch-mode power supplies, LED driver front-end rectification, and AC/DC adapter designs requiring stable component supply and long-term manufacturability.

Supply support for S10JC includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and consumer markets since 1979.

The S10JC belongs to TSC's S10x series of high-current surface-mount rectifiers, engineered specifically for reliable, cost-effective AC/DC conversion in high-volume power electronics where thermal robustness and SMT process compatibility are critical.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) rating for the S10JC?

The S10JC has a VRRM rating of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version D2102). This value is specific to the S10JC variant and differs from S10GC (400V), S10KC (800V), and S10MC (1000V) within the same family. The 600V rating ensures safe operation with sufficient margin against 265VAC line peaks.

Does the S10JC require moisture-sensitive handling prior to reflow soldering?

No, the S10JC is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking or dry-pack requirements. This simplifies manufacturing logistics and eliminates yield risk from moisture-induced popcorning during SMT assembly of the S10JC.

What is the forward voltage drop (VF) specification for the S10JC at rated current?

The S10JC has a maximum forward voltage drop of 1.1 V at IF = 10 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal modeling. At elevated junction temperatures, VF decreases slightly, but system design should use the 1.1 V max value for worst-case loss calculation.

Is the S10JC pin-compatible with other devices in the S10x series such as S10GC or S10MC?

Yes, all S10x series devices - including S10GC, S10JC, S10KC, and S10MC - share identical DO-214AB (SMC) package dimensions, pinout, and mechanical markings. They differ only in VRRM rating and corresponding device marking code; thus, the S10JC can be substituted on the same footprint provided the 600V rating meets system requirements.

What thermal resistance values are specified for the S10JC, and how do they impact PCB layout?

The S10JC specifies R_θJL = 10°C/W (junction-to-lead) and R_θJA = 47°C/W (junction-to-ambient, free air). These values mean that effective thermal design requires generous copper pour connected to both leads - especially the cathode - to leverage the low R_θJL. Layouts using the S10JC should avoid narrow traces and prioritize thermal vias under the leads to maintain TJ ≤ 150°C at 10A continuous.
