Product details
Overview
S5KB-13 from Diodes Incorporated is a 5A, 800V peak repetitive reverse voltage surface-mount standard recovery rectifier in SMB package, featuring 1.15V max forward voltage at 5.0A, 250µA max reverse leakage at +125°C, and 150A non-repetitive surge rating (8.3ms), used in AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the S5KB-13 datasheet, S5KB-13 pinout, S5KB-13 application, or S5KB-13 equivalent, key selection criteria include VRRM=800V, IO=5.0A @ TT=+120°C, thermal resistance RθJA=60°C/W, SMB package footprint compatibility, and automotive-grade qualification readiness per AEC-Q101.
Technical Context
This standard recovery rectifier operates with a 1.15V forward voltage drop at rated 5.0A DC output current, enabling efficient power conversion in line-frequency rectification stages. Its 800V VRRM rating supports universal-input (85–265VAC) SMPS designs without derating.
The device exhibits 250µA reverse leakage at +125°C and 28pF junction capacitance at 1MHz/4V, limiting high-frequency switching noise and EMI generation. Thermal performance is defined by RθJC=10°C/W and RθJL=8°C/W when mounted on specified copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak reverse voltage in bridge or single-phase rectifier configurations without breakdown. |
| IO | 5.0 A @ TT = +120°C - Continuous average output current capability under thermally managed PCB layout. |
| VFM | 1.15 V @ IF = 5.0A - Low conduction loss reduces heat generation in high-current linear rectification paths. |
| IFSM | 150 A (8.3ms) - Survives inrush surges during cold-start of AC-powered equipment. |
| IRM | 250 µA @ TA = +125°C - Low leakage preserves efficiency and stability in high-temperature environments. |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance defines required PCB copper area for thermal management. |
| CT | 28 pF @ 1MHz, 4V - Limits capacitive coupling and high-frequency noise in EMI-sensitive applications. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case per UL 94V-0, cathode indicated by band or notch, lead-free matte tin plating, 0.09g weight.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Industrial AC/DC Power Supply | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 50/60Hz AC mains into DC for 24V/48V industrial control systems. IC Role / Device Role / Timing Role: Standard recovery rectifier in single-phase bridge configuration. Use Value: 800V VRRM ensures margin over 265VAC peak (375V), while 5A IO sustains continuous load without forced cooling. | Use Scenario: Input rectification for constant-current LED drivers powering streetlights or signage. IC Role / Device Role / Timing Role: Primary-side diode in non-isolated buck-derived topology. Use Value: Low 1.15V VFM minimizes conduction loss at 3–5A typical LED string current, improving system efficiency. |

Use Scenario: AC input rectification for BLDC motor controllers in HVAC blowers or washing machine drives. IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier feeding DC link capacitor. Use Value: 150A IFSM withstands compressor startup surges; SMB package enables compact board layout. | Use Scenario: Bidirectional rectifier/inverter stage in line-interactive UPS with battery backup. IC Role / Device Role / Timing Role: Standard recovery diode handling bidirectional energy flow during transfer switching. Use Value: 250µA IRM at +125°C maintains low standby loss during extended battery mode operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06S | 600V VRRM, TO-277 package, 1.1V VFM @ 5A | Lower voltage rating; larger footprint; higher thermal mass | Select when lower cost and higher surge tolerance outweigh voltage margin needs. |
| ON Semi MUR580 | 800V VRRM, DO-214AC (SMA), 1.75V VFM @ 5A | Higher forward drop increases conduction loss; same voltage rating but different thermal profile | Choose only if SMA footprint is mandatory and thermal budget allows +0.6V extra drop. |
Compared with S5KB-13, STTH5L06S offers better surge resilience but sacrifices 200V blocking margin, while MUR580 matches VRRM but degrades efficiency due to higher VFM-making S5KB-13 optimal for space-constrained, thermally sensitive 800V rectification.

FAQ
What is the maximum junction temperature for S5KB-13?
The S5KB-13 has an operating junction temperature range of –65°C to +150°C. Its thermal design must ensure TJ does not exceed +150°C under worst-case ambient and power dissipation conditions, using RθJA=60°C/W and measured PCB copper thermal mass.
Is S5KB-13 qualified for automotive use?
S5KB-13 is not pre-qualified to AEC-Q101, but Diodes Incorporated offers automotive-grade variants (e.g., S5KBQ-13) with PPAP documentation and IATF 16949 manufacturing. Customers requiring automotive qualification should contact Diodes directly for change-controlled versions.
Can S5KB-13 replace a fast recovery diode in a PFC circuit?
No. S5KB-13 is a standard recovery rectifier (trr > 2 µs), unsuitable for active PFC boost stages where fast recovery (trr < 75 ns) or ultrafast diodes are required to minimize switching losses and EMI. It is intended for line-frequency rectification only.
What is the recommended PCB pad layout for SMB package?
Diodes specifies a suggested pad layout with dimensions C=4.30mm, G=1.80mm, X=2.50mm, X1=6.80mm, Y=2.30mm. Use 5.0 mm² copper pads (0.013 mm thick) for thermal relief, per RθJL=8°C/W test condition in the datasheet.
