Product details
Overview
S1K-13-F from Diodes Incorporated is a 1.0A surface-mount glass passivated silicon rectifier diode with 800V peak repetitive reverse voltage (VRRM), 30A non-repetitive surge rating, and 1.1V max forward voltage at 1.0A - used in AC/DC input stage rectification for industrial power supplies, LED drivers, and auxiliary power rails.
For engineers reviewing the S1K-13-F datasheet, S1K-13-F pinout, S1K-13-F application, or S1K-13-F equivalent, key selection criteria include VRRM derating at elevated temperature, thermal resistance (RθJT = 30°C/W), reverse recovery time (trr ≤ 3.0 µs), and SMA package compatibility with automated reflow assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz. It exhibits low reverse leakage (≤5.0 µA at 25°C, ≤100 µA at 125°C) and fast switching behavior with trr ≤ 3.0 µs, enabling efficient operation in offline SMPS front-end stages.
The glass passivated junction ensures high reliability and moisture resistance (J-STD-020 Level 1), while the SMA package supports high-density PCB layouts and automated placement. Thermal performance is defined with 5.0 mm² copper pad heat sinking per Diodes' AP02001 layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands transient line surges up to 800V in AC mains input circuits without breakdown. |
| IO @ TT=100°C | 1.0 A - Continuous average forward current rating when terminal temperature is held at 100°C. |
| IFSM (8.3ms) | 30 A - Survives single half-sine surge events common during cold-start or lightning-induced transients. |
| VFM @ IF=1.0A | ≤1.1 V - Limits conduction loss to ≤1.1W at rated DC output current, reducing thermal stress. |
| trr | ≤3.0 µs - Enables use in higher-frequency rectification (e.g., 100 kHz PFC boost outputs) with minimal switching loss. |
| RθJT | 30 °C/W - Junction-to-terminal thermal resistance measured on 5.0 mm² copper pad; defines heatsinking requirement for thermal design. |
| IRM @ 125°C | ≤100 µA - Low high-temp leakage preserves efficiency and stability in thermally constrained enclosures. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking, and 0.064 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Industrial Power Supply Input Rectification | LED Driver Auxiliary Rectification |
|---|---|
Use Scenario: Full-wave bridge rectification of 230VAC mains input in DIN-rail mounted 24V/5A industrial PSUs. IC Role / Device Role / Timing Role: Discrete rectifier diode in bridge configuration; handles 1.0A average output current with 800V VRRM margin. Use Value: Glass passivation and 30A surge rating ensure field reliability across wide ambient temperature ranges (−40°C to +85°C operating). | Use Scenario: Output rectification in isolated flyback LED drivers powering streetlight modules (36–72V, 0.7A). IC Role / Device Role / Timing Role: Secondary-side freewheeling diode; leverages low trr to minimize switching loss at 65kHz operation. Use Value: 1.1V VFM reduces conduction loss by ~12% vs. legacy 1N4007, lowering thermal load on compact PCB layouts. |
| AC-DC Adapter Bulk Capacitor Charging | Smart Meter Power Supply Front-End |
Use Scenario: Half-wave rectification feeding 470µF bulk capacitor in Class II 12V/1A wall adapters. IC Role / Device Role / Timing Role: Single diode in capacitive-input rectifier; conducts only during positive half-cycles. Use Value: RθJT = 30°C/W enables direct mounting on copper pour without heatsink, simplifying mechanical design. | Use Scenario: Mains-powered utility smart meter with dual 5V/3.3V rails and anti-tamper detection circuitry. IC Role / Device Role / Timing Role: Primary-side rectifier in auxiliary 5V supply; must survive 10kV ESD and 6kV surge per IEC 61000-4-5. Use Value: 30A IFSM and glass passivation provide validated surge endurance without adding MOVs or TVS devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR180 | Ultrafast recovery (trr ≈ 75 ns), higher VRRM (800V), but higher VFM (1.7V @ 1A) | Better for high-frequency PFC; less suitable for thermally constrained linear-regulated aux supplies | Prefer when trr < 100 ns is mandatory; accept higher conduction loss and cost. |
| Vishay VS-1K80 | Same VRRM (800V), same IO (1.0A), but SMB package (larger footprint, higher RθJA) | Requires larger PCB area; better thermal dissipation in free-air, worse in dense layouts | Choose only if SMB footprint already standardized in existing design or manual assembly is used. |
Compared with MUR180 and VS-1K80, S1K-13-F delivers optimal balance of surge robustness, thermal performance in SMA, and cost-efficiency for general-purpose 800V rectification - especially where trr ≤ 3.0 µs suffices and board space is constrained.

FAQ
What is the maximum allowable junction temperature for S1K-13-F?
The absolute maximum junction temperature is +150°C, but continuous operation above +125°C requires derating IO below 1.0A per the forward current derating curve in Figure 1. At terminal temperature (TT) = +100°C, IO remains rated at 1.0A; at TT = +125°C, IO drops to approximately 0.75A.
Can S1K-13-F be used in place of a 1N4007?
Yes, S1K-13-F replaces 1N4007 in most applications with advantages: higher VRRM (800V vs. 1000V), lower VFM (1.1V vs. 1.1V typ but tighter spec), faster trr (≤3.0 µs vs. ≥30 µs), and RoHS/Green compliance. However, its 1.0A IO rating matches 1N4007, and it lacks the latter's through-hole mounting.
Is the SMA package of S1K-13-F compatible with standard reflow profiles?
Yes - the matte tin finish and J-STD-020 Level 1 moisture sensitivity rating confirm compatibility with standard Pb-free reflow profiles (peak 260°C). Diodes' recommended profile includes ramp rate ≤3°C/s, preheat 150–200°C for 60–120s, and time above liquidus 60–90s at 235–245°C.
Does S1K-13-F require a heatsink in typical applications?
No external heatsink is required if the PCB provides adequate copper area: Diodes specifies 5.0 mm² of 0.013 mm thick copper pad per terminal to achieve RθJT = 30°C/W. In enclosed, still-air environments above +70°C ambient, additional copper pour or thermal vias are recommended to maintain TJ < 125°C.
