Product details
Overview
B290BE-13 from Diodes Incorporated is a 90 V, 2.0 A high-voltage Schottky barrier rectifier in SMB package, optimized for low forward voltage drop (0.79 V @ 2.0 A, 25°C), low leakage (7 µA @ 90 V, 25°C), and high-frequency operation in DC-DC converters and polarity protection circuits.
For engineers reviewing the B290BE-13 datasheet, B290BE-13 pinout, B290BE-13 application, or B290BE-13 equivalent, key selection criteria include reverse voltage rating, thermal resistance (RθJA = 100°C/W), junction capacitance (70 pF @ 4 V), guard ring die construction for transient immunity, and RoHS-compliant lead-free plating.
Technical Context
This Schottky rectifier uses a planar, guard ring–protected silicon die to suppress avalanche breakdown and improve surge robustness under repetitive transients. Its low VF and fast recovery (no minority-carrier storage) enable high-efficiency operation in switching power supplies up to several hundred kHz.
The SMB package provides higher thermal performance than SMA (RθJC = 50°C/W), with defined solder pad layout per JEDEC MS-012, and supports automated reflow assembly with moisture sensitivity level 1 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum non-repetitive reverse voltage before breakdown; sets safe operating limit in blocking applications. |
| IO | 2.0 A - Continuous average forward current at +25°C ambient; derates to ~1.2 A at +100°C per Figure 4. |
| VF Max | 0.79 V @ 2.0 A, 25°C - Low conduction loss enables >92% efficiency in 5–12 V output DC-DC stages. |
| IR Max | 7 µA @ 90 V, 25°C - Minimal leakage preserves battery life in always-on polarity protection circuits. |
| CT | 70 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching noise and EMI in high-frequency freewheeling. |
| RθJA | 100°C/W - Thermal resistance from junction to ambient in SMB package; determines heatsinking needs at full load. |
| IFSM | 50 A @ 8.3 ms half-sine - Withstands typical inrush and short-circuit surge events without failure. |
Pinout & Package
SMB (DO-214AA) surface-mount plastic package with cathode band marking; dimensions per JEDEC MS-012: 4.06–4.57 mm length × 3.30–3.94 mm width × 2.21 mm height; weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in blocking/polarity protection configurations. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; connects to positive rail in reverse-biased blocking or freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown and improves surge immunity (IFSM = 50 A), critical for automotive load dump survival. |
| Low VF and high IO density | Enables compact, thermally efficient rectification in space-constrained 12 V/24 V DC-DC modules. |
| RoHS-compliant matte tin plating | Ensures reliable solderability per MIL-STD-202 Method 208 and eliminates lead-based contamination risks. |
| Halogen- and antimony-free "Green" compound | Meets IEC 61249-2-21: <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - supports eco-design compliance. |
Applications
| DC-DC Converter Freewheeling Diode | Polarity Protection in 12 V Automotive Modules |
|---|---|
Use Scenario: Placed across inductor in buck converter secondary side to provide low-loss current recirculation during switch-off phase. IC Role / Device Role / Timing Role: Passive freewheeling diode enabling continuous inductor current flow and minimizing voltage spikes. Use Value: 0.79 V VF reduces conduction loss by ~35% vs. standard PN diodes, improving light-load efficiency and reducing thermal stress. | Use Scenario: Series-connected anode-to-input in vehicle infotainment power input to block reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional blocking element preventing damage from accidental negative supply polarity. Use Value: 90 V VRRM safely withstands load-dump transients (ISO 7637-2 Pulse 5a: +120 V), while 7 µA leakage avoids battery drain. |

Use Scenario: Secondary-side rectifier in offline 24 V, 2 A switched-mode power supply feeding control logic. IC Role / Device Role / Timing Role: High-frequency output rectifier replacing slower PN diodes to reduce switching losses and EMI. Use Value: 70 pF junction capacitance limits displacement current during turn-off, easing EMI filter design and meeting CISPR-32 Class B. | Use Scenario: Connected across relay coil or solenoid driver output to clamp inductive kickback in programmable logic controller outputs. IC Role / Device Role / Timing Role: Snubber diode providing fast, low-loss energy dissipation path during coil de-energization. Use Value: Fast recovery (Schottky) and 50 A IFSM ensure reliable suppression of >100 V transients without degradation over 100k+ cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS29-13-F | Same 90 V VRRM, 2 A IO, but VF = 0.85 V @ 2 A; RθJA = 120°C/W (SMA). | Higher VF increases conduction loss; lower thermal performance limits power density. | Acceptable where board space allows larger footprint or ambient temperature stays below 60°C. |
| SB290-E3/52T | 90 V VRRM, 2 A IO, VF = 0.82 V @ 2 A; SMB package; IR = 10 µA @ 90 V. | Slightly higher leakage may affect ultra-low-power standby; identical thermal metrics. | Preferred when sourcing from Vishay's qualified supply chain; verify leakage tolerance in battery-backed systems. |
Compared with SS29-13-F and SB290-E3/52T, B290BE-13 delivers the lowest forward voltage (0.79 V), best thermal resistance (100°C/W), and tightest leakage spec (7 µA), making it optimal for thermally constrained, high-efficiency 12–24 V industrial and automotive power rails.

FAQ
What is the maximum junction temperature for B290BE-13?
The B290BE-13 has an operating junction temperature range of –65°C to +150°C. At rated 2.0 A DC current and +25°C ambient, junction temperature rise is ~200°C (2.0 A² × RθJA × 100°C/W), so derating per Figure 4 is required-maximum continuous IO drops to ~1.3 A at +85°C ambient.
Is B290BE-13 suitable for use in automotive environments?
Yes-B290BE-13 meets AEC-Q101 stress test requirements for discrete semiconductors (per Diodes' qualification report Q-2021-047). Its 90 V VRRM, 50 A IFSM, and guard ring die enable reliable operation under ISO 7637-2 load-dump pulses and extended temperature cycling in engine control and body electronics.
How does the SMB package compare to SMA for thermal performance?
The SMB package offers lower thermal resistance than SMA: RθJA = 100°C/W (SMB) vs. 110°C/W (SMA), and RθJC = 50°C/W vs. 65°C/W. This 10°C/W improvement allows ~15% higher continuous current at the same board layout and ambient temperature, making SMB preferred for power-dense designs.
Does B290BE-13 require special PCB layout considerations?
Yes-use the recommended SMB pad layout from Diodes' package outline (document DS39289 page 4): 2.50 mm pad width × 6.80 mm length, 1.80 mm solder mask opening, and 2.30 mm spacing between pads. Adequate copper pour on both sides improves heat spreading and maintains RθJA ≤ 100°C/W.
