Taiwan Semiconductor Corporation S5J

Overview

S5J from Taiwan Semiconductor is a 5A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15 V at 5 A), high surge current capability (100 A), and 150°C maximum junction temperature - used in AC/DC front-end rectification for industrial SMPS and lighting converters.

For engineers reviewing the S5J datasheet, S5J pinout, S5J application, or S5J equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (13 °C/W junction-to-lead), reverse recovery time (1500 ns), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

The S5J is a single-die, standard recovery silicon rectifier optimized for cost-sensitive, medium-voltage power conversion where fast recovery is not required. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect design trade-offs favoring low conduction loss over switching speed.

Thermally, it delivers 13 °C/W junction-to-lead resistance and 47 °C/W junction-to-ambient resistance under standard mounting conditions, enabling reliable 5 A continuous operation with appropriate PCB copper area and ambient cooling.

Equivalent & Alternatives

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

Compared with STTH5L06 and MUR560, the S5J offers superior surge robustness (100 A) and SMD manufacturability in DO-214AB, but trades off recovery speed - making it optimal for line-frequency rectification where conduction loss dominates.

Availability

S5J is available at Aetrix Electronics and suitable for industrial SMPS, LED driver input stages, AC/DC adapters, and DC-DC converter input protection requiring stable component supply across multi-year production cycles.

Supply support for S5J 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, specializing in power devices, rectifiers, TVS diodes, and MOSFETs since 1979.

The S5J belongs to TSC's S5x series of general-purpose surface-mount rectifiers, engineered for high-reliability, cost-optimized AC/DC power conversion in industrial and lighting applications.

FAQ

What is the maximum repetitive peak reverse voltage rating for the S5J?

The S5J has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, verified per Taiwan Semiconductor's F2102 datasheet. This rating ensures safe operation with 420 V_RMS AC input lines plus standard safety margins. The S5J must not be operated beyond this voltage under repetitive conditions to prevent avalanche breakdown or premature failure.

Does the S5J have a specified reverse recovery time, and how does it impact circuit design?

Yes, the S5J has a typical reverse recovery time (t_rr) of 1500 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This relatively long recovery time indicates the S5J is intended for line-frequency or low-switching-frequency applications - using it in high-frequency converters (>50 kHz) may increase switching losses and EMI. Designers should verify dead-time margins in synchronous rectified topologies.

What is the thermal resistance from junction to lead for the S5J, and why does it matter?

The S5J has a junction-to-lead thermal resistance (R_θJL) of 13 °C/W, measured under standard test conditions. This value reflects efficient heat transfer from the silicon die directly through the leadframe to the PCB copper. It enables designers to estimate temperature rise without a heatsink - for example, at 5 A with 1.15 V forward drop, power dissipation is ~5.75 W, resulting in ~75°C rise above lead temperature - critical for layout and reliability validation.

Is the S5J compliant with RoHS and halogen-free standards?

Yes, the S5J is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor documentation. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated per J-STD-002. These qualifications make the S5J suitable for export to EU, China, and other regulated markets requiring strict environmental compliance.

What packaging and moisture sensitivity level does the S5J use?

The S5J is supplied in DO-214AB (SMC) package and shipped in tape-and-reel format (3,000 units per reel). Its moisture sensitivity level is rated MSL 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH and requires no baking prior to reflow soldering - simplifying SMT line integration and reducing process risk for high-volume manufacturing.
