Product details
Overview
S15KLW RVG from Taiwan Semiconductor is a 1.5A, 800V repetitive peak reverse voltage standard surface-mount silicon rectifier diode in SOD-123W package, featuring 50A surge current capability, 1.10V max forward voltage at 1.5A/25°C, and 175°C maximum junction temperature - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the S15KLW RVG datasheet, S15KLW RVG pinout, S15KLW RVG application, or S15KLW RVG equivalent, key selection criteria include VRRM=800V, IF=1.5A, IFSM=50A, VF≤1.10V @1.5A, and thermal resistance RθJA=85°C/W under standard PCB mounting conditions.
Technical Context
The S15KLW RVG is a single-die, unidirectional standard recovery rectifier optimized for high-efficiency AC/DC and DC/DC conversion stages. Its 800V VRRM rating supports 560V RMS input applications, and its 1.5A average forward current is derated linearly above 25°C ambient per the published derating curve.
Thermal performance is defined with reference to a 5mm × 5mm copper pad test board: RθJL = 29°C/W and RθJC = 31°C/W confirm efficient heat transfer to PCB leads and case, while moisture sensitivity level 1 (per J-STD-020) enables standard reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports 560 VRMS bridge input or 800 V transient clamping in flyback snubbers |
| IF(AVG) | 1.5 A - continuous conduction mode operation up to 175°C junction temperature |
| IFSM | 50 A - withstands 8.3 ms half-sine surge, enabling robust startup and fault handling |
| VF(max) | 1.10 V @ 1.5A, 25°C - contributes ≤1.65 W conduction loss at full rated current |
| IR(max) | 100 µA @ 125°C - ensures low leakage in high-temperature hold-up or standby circuits |
| RθJA | 85 °C/W - requires ≥5 mm × 5 mm Cu pad for thermal compliance at full load |
| CJ | 10 pF @ 4 V - minimizes capacitive coupling noise in high-frequency switching nodes |

Applications
| DC–DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24 V/48 V telecom or industrial DC–DC modules operating at 100–500 kHz. IC Role / Device Role / Timing Role: Standard recovery rectifier conducting forward current during transformer secondary positive half-cycle; blocks reverse voltage during flyback phase. Use Value: 800 V VRRM provides margin against reflected transients; 1.10 V VF limits power loss to ≤1.65 W at full load. | Use Scenario: Freewheeling or anti-parallel diode in 3-phase motor drive inverters with 600 V DC bus. IC Role / Device Role / Timing Role: Unidirectional conduction path for inductive kickback energy return; blocks reverse voltage during active switching intervals. Use Value: 50 A IFSM handles motor stall currents; 175°C TJ max supports operation in enclosed, thermally constrained enclosures. |
| AC–DC Adapters | Industrial Power Supplies |
Use Scenario: Output rectification in compact 65 W laptop adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Conducts during secondary winding positive voltage swing; blocks reverse voltage when primary switch is on. Use Value: SOD-123W package fits tight spacing constraints; 1.5 A rating supports continuous 5 V/12 A or 20 V/3.25 A outputs. | Use Scenario: Input bridge leg or auxiliary supply rectification in programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Converts AC line or intermediate DC rail to stable DC bias for control circuitry or gate drivers. Use Value: RθJA = 85°C/W allows thermal design with minimal heatsinking; 100 µA IR at 125°C prevents leakage-induced reset faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR1580 | 800 V VRRM, 1.5 A IF, but faster recovery (trr ≈ 75 ns vs. standard ~2 µs); higher VF (1.25 V typ) | Better suited for high-frequency PFC or ZVS circuits where reverse recovery loss dominates | Select MUR1580 only if trr reduction justifies higher conduction loss and cost premium |
| Vishay VS-1N5819HM3/85A | 40 V VRRM, 1 A IF - significantly lower voltage/current rating; Schottky construction, no reverse recovery | Limited to low-voltage (<30 V), low-power (<10 W) applications; unsuitable for 800 V systems | Not interchangeable; use only in legacy 5–12 V auxiliary rails where VRRM < 50 V suffices |
Compared with MUR1580 and VS-1N5819HM3/85A, the S15KLW RVG delivers optimal balance of 800 V blocking, 1.5 A current, and standard-recovery robustness for cost-sensitive 10–100 W industrial and adapter designs - without over-specifying speed or under-specifying voltage.

FAQ
What is the maximum junction temperature rating for the S15KLW RVG?
The S15KLW RVG has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings table. This allows operation in thermally demanding environments such as enclosed power supplies or high-ambient industrial settings. Derating begins linearly above 25°C ambient, and thermal design must ensure RθJA × Ploss + TA ≤ 175°C. The S15KLW RVG achieves this with its 85°C/W RθJA on a 5 mm × 5 mm Cu pad.
Does the S15KLW RVG have a halogen-free construction?
Yes, the S15KLW RVG is halogen-free in accordance with IEC 61249-2-21, and is also RoHS compliant. This is confirmed in the official product documentation under "Features" and "Mechanical Data." The molding compound and plating meet environmental compliance requirements for export and end-equipment certification. The S15KLW RVG carries no brominated flame retardants or chlorine-based additives.
What is the forward voltage specification for the S15KLW RVG at full rated current?
The S15KLW RVG has a maximum forward voltage (VF) of 1.10 V at 1.5 A and 25°C, per electrical specifications table. At 125°C junction temperature, VF drops to ≤1.05 V due to negative temperature coefficient of silicon. This value directly determines conduction loss: at 1.5 A, worst-case loss is 1.65 W. The S15KLW RVG maintains this performance across its qualified temperature range.
Is the S15KLW RVG suitable for automated SMT assembly?
Yes, the S15KLW RVG is explicitly designed for automated placement, as stated in its "Features" list. Its SOD-123W package meets J-STD-002 for solderability, has moisture sensitivity level 1 (no pre-bake required), and uses matte tin-plated leads compatible with standard reflow profiles. The S15KLW RVG is supplied in 10,000-piece tape-and-reel packaging for pick-and-place compatibility.
What does the "RVG" suffix indicate in S15KLW RVG?
The "RVG" suffix in S15KLW RVG denotes Taiwan Semiconductor's internal revision and packaging code, indicating compliance with RoHS, halogen-free, and moisture sensitivity level 1 requirements. It is not a functional variant - all electrical and thermal parameters match the base S15KLW designation. The S15KLW RVG shares identical VRRM=800 V, IF=1.5 A, and SOD-123W package with other S15KLW-marked units in the same production lot.
