Product details
Overview
S5A M6G from Taiwan Semiconductor is a surface-mount general-purpose silicon rectifier diode with 5 A average forward current, 50 V repetitive peak reverse voltage (VRRM), and DO-214AB (SMC) package. It features low forward voltage drop (max 1.15 V at 5 A, 25°C), high surge capability (100 A IFSM), and operates up to 150°C junction temperature - used in AC/DC input stages of compact power adapters and offline SMPS.
For engineers reviewing the S5A M6G datasheet, S5A M6G pinout, S5A M6G application, or S5A M6G equivalent, key selection considerations include its 50 V VRRM rating, 1.15 V VF max at rated current, 10 µA IR at 25°C, 1500 ns trr, and DO-214AB mechanical compatibility with automated SMT assembly lines.
Technical Context
This single-die, single-phase standard recovery rectifier uses glass-passivated junction technology for robustness and moisture resistance (J-STD-020 Level 1). Its thermal design supports 13°C/W junction-to-lead resistance and 47°C/W junction-to-ambient resistance under natural convection.
The device exhibits typical junction capacitance of 60 pF at 1 MHz / 4 V and reverse recovery time of 1500 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions - suitable for non-critical switching applications below 100 kHz where soft recovery is not required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse voltage before breakdown; defines safe AC input voltage handling in bridge or single-diode configurations |
| IF(AV) | 5 A - continuous average forward current at TC = 110°C; determines heatsink sizing in linear-conduction applications |
| VF(max) | 1.15 V @ 5 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in power stage |
| IFSM | 100 A @ 8.3 ms - peak non-repetitive surge current capacity; critical for inrush and fault-current tolerance |
| trr | 1500 ns - reverse recovery time; limits usable frequency range and influences EMI in switching circuits |
| RθJL | 13 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour thermal path design without external heatsink |
| IR(max) | 10 µA @ 25°C - leakage current at rated VR; affects standby power and high-impedance bias networks |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode-indicating band on one end; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary side; must withstand full surge current and thermal cycling |
| Cathode | Forward current exit point | Marked by band; ties to DC bus or output capacitor; polarity-sensitive in bridge and clamp configurations |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reliability under humidity and thermal stress per J-STD-020 Level 1 |
| Low VF (1.15 V max) | Reduces conduction losses by ~15% vs. comparable 1N54xx series at 5 A, improving adapter efficiency |
| 100 A IFSM rating | Supports cold-start surges in universal-input 85–265 VAC adapters without derating |
| DO-214AB (SMC) footprint | Standardized 7.11 × 6.22 mm outline compatible with high-speed pick-and-place and reflow profiles |
| RoHS & halogen-free | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated markets |
Applications
| AC/DC Power Adapters | Offline Switch-Mode Power Supplies |
|---|---|
Use Scenario: Universal-input (85–265 VAC) wall adapters for consumer electronics. IC Role / Device Role / Timing Role: Input rectifier in single-phase bridge configuration. Use Value: 5 A rating and 100 A surge handle startup inrush; 1.15 V VF minimizes heat in sealed enclosures. | Use Scenario: Primary-side rectification in flyback or forward converters for industrial control modules. IC Role / Device Role / Timing Role: Output rectifier in secondary-side synchronous or diode-based topology. Use Value: 150°C TJ max allows operation near transformer windings; DO-214AB fits constrained board space. |
| LED Driver Circuits | DC-DC Converter Input Stages |
Use Scenario: Constant-current LED drivers for commercial lighting with AC mains input. IC Role / Device Role / Timing Role: Bridge rectifier element converting AC line to pulsating DC for bulk capacitor charging. Use Value: 10 µA IR at 25°C ensures minimal standby loss; glass passivation prevents humidity-induced leakage drift. | Use Scenario: Input rectification in isolated DC-DC modules accepting 24–48 VDC input with transient protection. IC Role / Device Role / Timing Role: Clamp or freewheeling diode in boost or buck-boost front-end stages. Use Value: 1500 ns trr acceptable for <100 kHz operation; RθJL = 13°C/W simplifies thermal pad layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR550 | Ultrafast recovery (75 ns trr), higher VF (1.7 V typ), same DO-214AB package | Better suited for high-frequency (>100 kHz) PFC or resonant topologies requiring faster switching | Select when trr < 200 ns is mandatory; accept higher conduction loss and cost premium |
| Vishay VS-5EWH05FN-M3 | Enhanced avalanche rating (EAS = 120 mJ), same 50 V VRRM and 5 A IF, same package | Preferred in automotive or industrial systems subject to load dump or inductive switching transients | Choose when system-level surge immunity beyond IFSM is required; no change to layout or thermal design |
Compared with MUR550 and VS-5EWH05FN-M3, the S5A M6G offers lower VF and cost-effective standard recovery performance ideal for cost-sensitive, thermally constrained 50–100 kHz AC/DC applications - trading speed for efficiency and ruggedness in non-resonant designs.

FAQ
What is the maximum junction temperature rating for the S5A M6G?
The S5A M6G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in thermally dense environments such as enclosed power adapters or LED drivers. Derating curves show usable current drops to ~3.5 A at TC = 110°C. The S5A M6G must be mounted on adequate copper area to maintain TJ ≤ 150°C under full load.
Does the S5A M6G have a specified reverse recovery time (trr)?
Yes, the S5A M6G has a specified reverse recovery time of 1500 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This value is confirmed in the Electrical Specifications table and applies directly to the S5A M6G variant. The S5A M6G is classified as a standard recovery rectifier, not ultrafast - making it appropriate for applications operating below 100 kHz.
Is the S5A M6G RoHS and halogen-free compliant?
Yes, the S5A M6G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements are explicitly documented in the FEATURES section of the official Taiwan Semiconductor datasheet (Version F2102). The S5A M6G uses matte tin-plated leads and UL 94V-0 molding compound.
What is the marking code for the S5A M6G on the device body?
The marking code for the S5A M6G is "S5A", printed on the cathode-banded end of the DO-214AB package. This matches the ordering code convention defined in the datasheet: "S5x" where "x" denotes voltage grade - "A" = 50 V. The S5A M6G does not include additional date or factory codes in its visible marking.
Can the S5A M6G replace a 1N5408 in a design?
The S5A M6G is not a direct replacement for the 1N5408 due to differing packages and ratings: 1N5408 is DO-201AD (axial lead) with 1000 V VRRM and 3 A IF, while S5A M6G is DO-214AB (SMD) with 50 V VRRM and 5 A IF. However, the S5A M6G can replace axial 1N5401–1N5404 variants in SMT designs requiring 50–200 V VRRM and higher current - provided layout and thermal design accommodate the SMC footprint and lower voltage rating.
