Product details
Overview
S5A V6G from Taiwan Semiconductor is a 5 A, 50 V 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), and high surge capability (100 A, 8.3 ms). It serves as a primary AC/DC input rectifier in compact off-line power supplies for consumer adapters and LED drivers.
For engineers reviewing the S5A V6G datasheet, S5A V6G pinout, S5A V6G application, or S5A V6G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (RθJL = 13 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
The S5A V6G is a single-die, standard recovery rectifier with a typical reverse recovery time of 1500 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions. Its junction-to-lead thermal resistance of 13 °C/W enables direct heat conduction to PCB copper, supporting continuous 5 A operation at ≤125 °C ambient when properly mounted.
Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band, and the DO-214AB (SMC) case meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 5 A - Continuous forward current rating at TA = 75°C with adequate PCB copper area |
| VRRM | 50 V - Maximum non-repetitive peak reverse voltage; defines safe AC input voltage headroom (e.g., 35 V RMS) |
| IFSM (8.3 ms) | 100 A - Surge withstand capability for cold-start inrush in SMPS input stages |
| VF (max) | 1.15 V @ 5 A, 25°C - Directly impacts conduction loss and thermal design in 5–12 W adapter designs |
| IR (max) | 10 µA @ 25°C, 50 V - Low leakage ensures minimal standby power loss in no-load conditions |
| RθJL | 13 °C/W - Enables efficient heat transfer from die to PCB pad without external heatsink |
| trr | 1500 ns - Standard recovery speed suitable for <100 kHz switching topologies (e.g., flyback, buck-derived) |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, dual-lead, cathode-banded case. Weight: 0.210 g. Molding compound: UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode (Lead 2, banded end) | DC output / bulk capacitor positive node | Delivers rectified output; requires thermal relief and ≥200 mil copper pour for 5 A handling |
Key Features
| Feature | Design Value |

| MSL Level 1 | Allows unlimited floor life and reflow without baking-reduces manufacturing overhead in high-volume SMT lines |
| RoHS + halogen-free | Meets IEC 61249-2-21 and global environmental compliance requirements for consumer and industrial end products |
| Matte tin plating | Guarantees consistent wetting and void-free solder joints per J-STD-002, critical for automated assembly yield |
Applications
| LED Lighting Driver | USB-C Wall Adapter |
|---|---|
Use Scenario: Rectifying 50/60 Hz or high-frequency AC from transformer secondary in constant-current LED driver modules. IC Role / Device Role / Timing Role: Primary input rectifier converting AC to pulsating DC before bulk capacitor and PWM controller stage. Use Value: 5 A rating supports up to 40 W output; 1.15 V VF minimizes self-heating in enclosed plastic housings. | Use Scenario: Input bridge or half-wave rectification in compact 18–30 W USB PD adapters with integrated flyback controllers. IC Role / Device Role / Timing Role: Front-end rectifier handling universal AC input (90–264 VAC) after EMI filter and before PFC or direct flyback stage. Use Value: MSL 1 and tape-and-reel packaging enable seamless SMT integration; DO-214AB footprint fits tight board spacing. |
| Industrial Sensor Power Supply | Smart Home Gateway AC/DC Module |
Use Scenario: Providing isolated 5 V/3.3 V bias rails for RS-485 transceivers and microcontrollers in factory-floor sensors. IC Role / Device Role / Timing Role: Secondary-side rectifier on small signal transformer outputs, operating at ≤100 kHz. Use Value: 1500 ns trr avoids excessive switching loss in low-power flybacks; 13 °C/W RθJL sustains operation at 70°C ambient. | Use Scenario: AC/DC conversion in space-constrained smart speaker or hub power modules requiring low standby consumption. IC Role / Device Role / Timing Role: Standby rectifier feeding auxiliary supply for MCU wake-up circuitry and communication ICs. Use Value: 10 µA max IR at 25°C limits no-load input power to <30 mW; halogen-free construction satisfies EU EcoDesign directives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 from STMicroelectronics | 600 V VRRM, 5 A IF, 1.7 V VF (max), TO-220AC package | Higher voltage rating but larger through-hole package; not SMT-compatible | Select only if >50 V reverse stress or legacy through-hole assembly is required |
| MBR540 from ON Semiconductor | 40 V VRRM, 5 A IF, 0.55 V VF (typ), Schottky architecture, DO-214AB | Lower VF reduces conduction loss but limited to ≤40 V circuits; higher IR at elevated temperature | Prefer for <40 V input systems where efficiency >5% matters; avoid in 50 V-rated designs due to derating margin |
Compared with STTH5L06 and MBR540, the S5A V6G provides optimal balance of 50 V rating, SMT compatibility, low-cost standard recovery performance, and MSL 1 manufacturability-making it ideal for cost-sensitive, volume-consumer AC/DC front ends where 1.15 V VF and 1500 ns trr are sufficient.

FAQ
What is the maximum junction temperature rating for the S5A V6G?
The S5A V6G has a maximum junction temperature (TJ) of +150°C, with an operating range from –55°C to +150°C. This allows reliable operation in enclosed environments such as sealed LED drivers or wall adapters, provided thermal design maintains junction temperature below this limit using the specified RθJL = 13 °C/W path to PCB copper. The S5A V6G must not exceed this rating during transient or steady-state conditions.
Is the S5A V6G suitable for use in RoHS-compliant and halogen-free designs?
Yes, the S5A V6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound and matte tin-plated leads meet these environmental standards without compromise to electrical or thermal performance. Designers can confidently specify the S5A V6G in consumer, medical, and industrial products requiring full substance compliance documentation. The S5A V6G carries no exemptions and supports full material declarations.
Does the S5A V6G have a defined moisture sensitivity level (MSL)?
Yes, the S5A V6G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard reflow profiles without pre-baking. This eliminates process steps in high-speed SMT lines and improves first-pass yield. The S5A V6G's MSL 1 classification is verified by TSC's qualification testing and applies to all units shipped in tape-and-reel packaging.
What is the reverse recovery time (trr) specification for the S5A V6G?
The S5A V6G has a typical reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value reflects its standard recovery behavior and is appropriate for operation in flyback, buck-derived, and line-frequency rectification circuits up to ~100 kHz. The S5A V6G is not intended for ultra-fast or soft-recovery applications where trr < 500 ns is required.
Can the S5A V6G replace higher-voltage S5x variants like S5G or S5J in a 50 V design?
No-the S5A V6G is specifically rated for 50 V VRRM and must not be substituted with higher-voltage variants unless the circuit's reverse stress remains within the S5A V6G's 50 V limit. While S5G (400 V) and S5J (600 V) share the same DO-214AB package and 5 A rating, their higher voltage capability does not improve performance at 50 V and may incur unnecessary cost or parameter trade-offs. The S5A V6G is the correct variant for 50 V applications.
