Product details
Overview
B150BE-13 from Diodes Incorporated is a 50 V, 1 A surface-mount Schottky barrier rectifier in SMB package with 0.65 V max forward voltage at 1 A and 0.1 mA max reverse leakage at 50 V and +25°C, used for boost, blocking, and recirculating diode functions in DC-DC converters and power supplies.
For engineers reviewing the B150BE-13 datasheet, B150BE-13 pinout, B150BE-13 application, or B150BE-13 equivalent, key selection criteria include forward voltage drop at rated current, high-temperature reverse leakage stability, thermal resistance (90°C/W junction-to-ambient), SMB package footprint compatibility, and RoHS/Green compliance for industrial and consumer power designs.
Technical Context
This Schottky rectifier uses a planar epitaxial construction to achieve low VF and stable IR across temperature. Its 50 V VRRM rating supports standard 3.3 V–24 V input rails with margin, while the 30 A non-repetitive surge rating enables robustness against transient overcurrent events in switching topologies.
The device exhibits 45 pF typical junction capacitance at 4.0 V and 1 MHz, supporting moderate-frequency rectification up to ~500 kHz. Thermal performance is defined for FR-4 PCB mounting with 0.2" × 0.25" copper pad, delivering 90°C/W RθJA and 40°C/W RθJC in SMB package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit for 36 V nominal bus applications. |
| IO(AV) | 1 A - Average forward current rating; defines continuous conduction capability under thermal derating per Figure 4. |
| VF(max) | 0.65 V @ 1 A, +25°C - Low forward drop reduces conduction loss and improves efficiency in 12 V/24 V DC-DC stages. |
| IR(max) | 0.1 mA @ 50 V, +25°C - Tight leakage spec ensures minimal standby power loss and thermal stability at ambient temperatures. |
| RθJA | 90 °C/W - Junction-to-ambient thermal resistance on standard FR-4 board; determines temperature rise under 1 A load. |
| CT(typ) | 45 pF @ 4 V, 1 MHz - Junction capacitance affects high-frequency switching noise and EMI in buck/boost converters. |
Pinout & Package
Package: SMB (Surface Mount Small Outline) - 4.06 mm × 4.57 mm body, 1.96 mm × 2.21 mm height, cathode band marking, matte tin-plated copper leadframe, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost, source in synchronous rectifier). |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by band; ties to output rail or higher-potential node; blocks reverse current during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at 1 A | 0.65 V max enables ≥2% efficiency gain vs. standard PN rectifiers in 12 V output converters. |
| Stable high-temp IR | 0.1 mA @ +25°C and <8.0 mA @ +125°C prevents thermal runaway in enclosed power modules. |
| SMB package thermal performance | 90°C/W RθJA and 40°C/W RθJC support 1 A operation without heatsink on standard PCB layout. |
| RoHS & Green compliant | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); meets EU Directive 2011/65/EU and IPC-1752A. |
Applications
| Boost Diode in DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Placed in the high-side path of a step-up converter to prevent reverse current flow when the switch is off. IC Role / Device Role / Timing Role: Unidirectional current valve enabling energy transfer from input inductor to output capacitor during off-time. Use Value: 0.65 V VF minimizes power loss at 1 A peak currents; 50 V rating covers 36 V solar array inputs with safety margin. | Use Scenario: Isolates battery from PV panel during night or low-light conditions to prevent discharge. IC Role / Device Role / Timing Role: Reverse-biased blocking element that conducts only when panel voltage exceeds battery voltage. Use Value: 0.1 mA IR at +25°C ensures negligible nighttime battery drain; SMB footprint fits compact outdoor-rated enclosures. |
| Recirculating Diode in Relay Drivers | Output Rectifier in AC-DC Adapters |
Use Scenario: Provides freewheeling path for inductive kickback when relay coil is de-energized. IC Role / Device Role / Timing Role: Clamp diode absorbing stored magnetic energy within microseconds after switch turn-off. Use Value: 30 A IFSM withstands short-duration coil transients; low VF avoids excessive heating during repeated actuation. | Use Scenario: Converts transformer secondary AC to regulated DC in offline flyback or forward converters. IC Role / Device Role / Timing Role: Secondary-side unidirectional conduction element synchronized with transformer polarity reversal. Use Value: 45 pF CT limits high-frequency ringing; 90°C/W RθJA allows natural convection cooling in sealed adapter housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB150-E3/54 (Vishay) | Same 50 V VRRM, 1 A IO, but VF = 0.75 V max @ 1 A; RθJA = 95°C/W in SMA. | Higher VF increases conduction loss; SMA package has larger footprint than SMB. | Select if SMA board space available and legacy Vishay sourcing preferred. |
| SS15 (ON Semiconductor) | 50 V VRRM, 1 A IO, VF = 0.55 V typ but IR = 0.5 mA @ 50 V, +25°C - 5× higher leakage. | Lower VF improves efficiency but elevated IR risks thermal instability above 85°C ambient. | Select for cooler ambient environments where leakage-driven losses are acceptable. |
Compared with SB150-E3/54 and SS15, B150BE-13 delivers optimal balance of low VF (0.65 V), ultra-low IR (0.1 mA), and compact SMB thermal performance (90°C/W), making it preferred for space-constrained, thermally demanding 1 A rectification tasks.

FAQ
What is the maximum junction temperature for continuous operation of B150BE-13?
The B150BE-13 has an operating junction temperature range of –55°C to +150°C. For reliable long-term operation at 1 A average current, thermal design must ensure TJ remains ≤150°C under worst-case ambient and power dissipation conditions, using its 90°C/W RθJA and 40°C/W RθJC values on specified PCB layout.
Does B150BE-13 have a cathode band marking, and how is polarity identified?
Yes, B150BE-13 features a visible cathode band on the SMB package body, aligned with the cathode terminal. The band corresponds to the end of the package where the cathode lead exits; this matches standard diode polarity conventions and is verified in Diodes' DS39267 Rev. 3–2, page 2 (top view diagram).
Can B150BE-13 replace B150AE-13 in existing designs?
B150BE-13 (SMB) and B150AE-13 (SMA) share identical electrical specs (50 V, 1 A, 0.65 V VF, 0.1 mA IR) but differ mechanically: SMB is larger (4.57 mm length) than SMA (2.92 mm), requiring PCB pad redesign. Thermal resistance also differs (90°C/W vs. 95°C/W), affecting thermal margin.
Is B150BE-13 suitable for automotive applications per AEC-Q101?
No, B150BE-13 is not AEC-Q101 qualified. It is rated for industrial temperature range (–55°C to +150°C) and RoHS/Green compliance, but lacks automotive-specific qualification testing such as HTOL, TCT, and ESD per AEC-Q101. Use only in non-safety-critical automotive subsystems with customer validation.
