Product details
Overview
B290-13-F from Diodes Incorporated is a 2.0A, 90V peak repetitive reverse voltage Schottky barrier rectifier in SMB package, featuring 0.79V max forward voltage at 2.0A/25°C, 50A non-repetitive surge rating, and guard ring die construction for transient protection-used in low-voltage, high-frequency inverters and polarity protection circuits.
For engineers reviewing the B290-13-F datasheet, B290-13-F pinout, B290-13-F application, or B290-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (15°C/W junction-to-terminal), reverse leakage at elevated temperature, surge capability, and SMB package compatibility with automated SMT assembly.
Technical Context
This discrete Schottky diode employs a guard ring die structure to enhance transient voltage immunity and reduce avalanche-induced failure risk. Its low VF (≤0.79V @ 2.0A, 25°C) and low CT (75pF @ 4V, 1MHz) support high-efficiency, high-switching-frequency operation in DC-DC converters and freewheeling paths.
Thermal performance is defined by RθJT = 15°C/W (junction-to-terminal), enabling 2.0A average forward current at terminal temperature ≤125°C. The device operates across –65°C to +150°C and meets J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum peak repetitive reverse voltage; sets upper limit for blocking capability in rectification or polarity protection |
| IF(AV) | 2.0 A - average forward current at TT = +125°C; defines continuous conduction capability under thermal-limited conditions |
| VF | 0.79 V max @ 2.0A, 25°C - low forward drop reduces conduction loss and improves system efficiency in power conversion stages |
| IFSM | 50 A @ 8.3ms half-sine - surge rating enables robustness against inrush and fault transients without catastrophic failure |
| IR | 7.0 µA max @ 90V, 25°C - low leakage preserves battery life and minimizes standby power loss in low-power systems |
| RθJT | 15 °C/W - thermal resistance from junction to terminal; critical for estimating junction temperature rise under PCB trace cooling |
| CT | 75 pF @ 4V, 1MHz - low capacitance limits switching losses and EMI generation in high-frequency applications |
Pinout & Package

Applications
| DC-DC Converter Output Rectification | Automotive Polarity Protection |
|---|---|
Use Scenario: Secondary-side synchronous rectification replacement in 12V-input, 3.3V/5V-output buck converters. IC Role / Device Role / Timing Role: Uncontrolled rectifier providing low-loss unidirectional current path during freewheeling phase.

IC Role / Device Role / Timing Role: Series-blocking element preventing damage during accidental battery cable reversal. Use Value: 90V VRRM withstands load-dump transients up to ISO 7637-2 Pulse 5a, while 50A IFSM handles jump-start surges. |
| High-Frequency Inverter Freewheeling | Industrial Power Supply Input Stage |

Use Value: 2.0A IF(AV) and 15°C/W RθJT allow reliable operation without heatsink in thermally constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB290-E3/52T (Vishay) | Same SMB package, 90V VRRM, but VF = 0.85V max @ 2A/25°C; RθJT = 18°C/W | Slightly higher conduction loss and thermal resistance; less suitable for thermally dense 2.0A continuous designs | Select when Vishay's qualification pedigree or long-term availability is prioritized over minimal VF/RθJT |
| SS29 (ON Semiconductor) | SMB package, 90V VRRM, VF = 0.82V max @ 2A/25°C; IR = 10µA @ 90V/25°C (vs. 7µA) | Higher leakage may impact ultra-low-power standby performance; otherwise functionally aligned | Prefer for ON Semi–qualified platforms where cross-manufacturer validation is restricted |
Compared with SB290-E3/52T and SS29, B290-13-F delivers the lowest forward voltage and best thermal resistance in the SMB 2A/90V class-critical for minimizing board-level temperature rise and maximizing efficiency in space-constrained power supplies.

FAQ
What is the maximum junction temperature for B290-13-F?
The absolute maximum junction temperature is +150°C, with continuous operation limited to terminal temperature ≤125°C to sustain 2.0A average forward current. Derating curves in DS30021 Rev. 13–2 show linear reduction to zero current at +150°C terminal temperature.
Is B290-13-F suitable for automotive applications?
Yes-B290-13-F meets AEC-Q101 stress test requirements when qualified as B290Q-13-F (separate automotive-grade part number). Standard B290-13-F is widely used in non-safety-critical automotive subsystems including infotainment, lighting, and body electronics.
How does the guard ring die construction improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, suppressing premature edge breakdown during reverse-biased transients. This extends operational lifetime under repetitive surge conditions like load dump or inductive kickback in automotive and industrial environments.
Can B290-13-F replace a standard PN rectifier in existing designs?
Yes-its SMB footprint and cathode-band polarity match common PN diodes. However, verify that reverse leakage (7µA max @ 25°C) and lower reverse voltage margin (90V vs. typical 100V+ PN diodes) meet system requirements before substitution.
