Product details
Overview
S1KB-13-F from Diodes Incorporated is a 1.0A, 800V peak repetitive reverse voltage (VRRM), glass passivated surface-mount silicon rectifier diode in the SMB package. It delivers 30A non-repetitive peak forward surge current (IFSM), exhibits ≤1.1V forward voltage (VFM) at 1.0A, and features 3.0μs maximum reverse recovery time (trr), making it suitable for AC/DC input rectification in compact power supplies.
For engineers reviewing the S1KB-13-F datasheet, S1KB-13-F pinout, S1KB-13-F application, or S1KB-13-F equivalent, key selection criteria include its 800V blocking capability, thermal resistance of 30°C/W (junction-to-terminal), RoHS-compliant matte tin plating, and SMB package compatibility with automated assembly processes.
Technical Context
This SMB-packaged rectifier operates as a single-phase, half-wave silicon junction diode optimized for general-purpose AC line rectification and DC power conversion. Its glass passivated die construction ensures high reliability under repeated surge stress, while the 30A IFSM rating supports transient overload conditions typical in offline switch-mode power supply (SMPS) front-ends.
The device's 3.0μs max trr and 10pF typical junction capacitance support moderate-frequency operation up to ~100kHz without excessive switching loss. Its derated average forward current drops to 0.4A at +100°C terminal temperature, requiring appropriate PCB copper pad heatsinking per AP02001 layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse voltage the diode blocks reliably in repetitive operation; defines AC input voltage range compatibility (e.g., 380–400VAC RMS systems). |
| IO @ TT=100°C | 1.0 A - Average forward current rating at 100°C terminal temperature; requires ≥5.0 mm² copper pad for thermal management. |
| VFM @ IF=1.0A | ≤1.1 V - Forward voltage drop determining conduction loss (1.1W max at 1A); impacts efficiency and thermal design in linear or low-frequency rectifiers. |
| IFSM (8.3ms) | 30 A - Non-repetitive surge current capacity; enables survival during cold-start inrush or lightning-induced transients. |
| trr (max) | 3.0 μs - Reverse recovery time limiting usable switching frequency; suitable for 50/60Hz–100kHz applications but not high-frequency synchronous rectification. |
| RθJT | 30 °C/W - Junction-to-terminal thermal resistance; used with PCB copper area to calculate junction temperature rise under load. |
| IRM @ 125°C | 100 μA - Maximum reverse leakage at elevated temperature; affects standby power loss in high-impedance hold-up circuits. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case meeting UL 94V-0 flammability rating; polarity indicated by cathode band on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary low-side; must route with adequate trace width for 1A continuous current. |
| Cathode | Forward current exit / reverse voltage reference | Connected to bulk capacitor positive rail; cathode band marking aligns with PCB silkscreen polarity indicator. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates need for hermetic sealing; provides stable parameter performance and >1000-hour HTRB reliability under bias at 125°C. |
| Lead-free, RoHS-compliant finish | Matte tin plating meets MIL-STD-202 solderability requirements and supports lead-free reflow profiles (J-STD-020 Level 1). |
| Automated assembly optimized | SMB footprint and 0.093g weight ensure stable placement and minimal tombstoning risk on high-speed pick-and-place equipment. |
| Halogen & antimony free | Complies with "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb); satisfies stringent environmental compliance for industrial and consumer end markets. |
Applications
| AC/DC Adapter Input Rectification | Industrial Power Supply Front-End |
|---|---|
Use Scenario: Converts 100–240VAC universal input to pulsating DC before bulk capacitor filtering in wall-plug adapters. IC Role / Device Role / Timing Role: Unidirectional current valve enabling half-wave or full-wave bridge operation; no timing function. Use Value: 800V VRRM safely handles 240VAC + 30% line surge; 30A IFSM withstands capacitor-charging inrush without degradation. | Use Scenario: Rectifies 3-phase or high-voltage single-phase AC in programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Discrete power semiconductor performing mains-level energy conversion; operates in linear conduction mode only. Use Value: UL 94V-0 package and -65°C to +150°C operating range support harsh industrial ambient conditions and long-term field reliability. |
| LED Driver Bulk Rectification | Appliance Control Board Power Input |
Use Scenario: Provides DC bus for constant-current LED driver ICs in commercial lighting fixtures. IC Role / Device Role / Timing Role: Primary rectifier in isolated flyback or non-isolated buck-derived topologies; zero timing dependency. Use Value: Low 1.1V VFM minimizes conduction loss at 350mA–1A drive currents, improving system efficiency over lower-voltage alternatives. | Use Scenario: Supplies unregulated DC to microcontroller and sensor power rails in washing machine or HVAC control boards. IC Role / Device Role / Timing Role: Mains interface protection and conversion element; interfaces directly with EMI filter and fuse. Use Value: SMB package allows dense layout near IEC inlet; cathode band marking ensures consistent polarity during automated assembly and field service replacement. |
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 MUR180EB | 800V VRRM, 1.0A IO, but ultrafast trr = 75ns; higher cost; TO-277 package (3-lead, anode-cathode-anode). | Designed for high-frequency SMPS where fast recovery reduces switching loss; unsuitable for space-constrained SMB layouts. | Select only if trr <100ns is required and board redesign accommodates TO-277 footprint and dual-anode configuration. |
| Vishay VS-1KBB80 | 800V VRRM, 1.0A IO, SMB package, but trr = 4.0μs (slower), IRM = 5.0μA @25°C (lower leakage). | Better leakage performance at room temperature; marginally slower recovery limits use in higher-frequency designs. | Prefer when low standby current dominates design priority and operating frequency remains below 50kHz. |
Compared with MUR180EB and VS-1KBB80, S1KB-13-F offers the optimal balance of surge robustness (30A IFSM), SMB footprint compatibility, and cost-effective general-purpose rectification-without over-specifying speed or leakage for standard 50/60Hz applications.

FAQ
What is the maximum allowable junction temperature for S1KB-13-F?
The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent parametric shift or catastrophic failure. Derating curves show that average forward current must be reduced to 0.4A at +100°C terminal temperature, assuming 5.0 mm² copper pad heatsinking per datasheet Note 5.
Can S1KB-13-F replace S1KB-13 in existing designs?
Yes-S1KB-13-F is the RoHS-compliant, lead-free version of S1KB-13, with identical electrical specifications, SMB package dimensions, and thermal performance. The "-F" suffix denotes matte tin plating and halogen/antimony-free construction; no layout or thermal redesign is required for drop-in replacement.
Is S1KB-13-F suitable for use in a full-wave bridge configuration?
Yes-four S1KB-13-F diodes can be assembled into a discrete full-wave bridge rectifier. Each device handles one quadrant; the 800V VRRM rating ensures safe operation with 400VAC input. Ensure matched thermal mounting and symmetrical PCB copper pour to avoid current imbalance under load.
Does S1KB-13-F require snubber circuitry in 60Hz rectifier applications?
No-snubbers are not required for standard 60Hz half-wave or full-wave rectification due to the device's 3.0μs trr and inherent soft recovery behavior. Snubbers may be added only if ringing is observed during capacitor charging transients or in conjunction with highly inductive loads exceeding datasheet surge ratings.
