Product details
Overview
SBR3150SB-13 from Diodes Incorporated is a 3.0A, 150V surface-mount Schottky barrier rectifier in SMB package, featuring low forward voltage (0.61V @ 3A, 125°C), 80A non-repetitive surge rating, and guard ring die construction for transient protection-used in DC/DC converters, solar microinverters, and polarity protection circuits.
For engineers reviewing the SBR3150SB-13 datasheet, SBR3150SB-13 pinout, SBR3150SB-13 application, or SBR3150SB-13 equivalent, key selection criteria include forward voltage at high junction temperature, thermal resistance (104°C/W), surge robustness (80A), RoHS-compliant lead-free plating, and SMB footprint compatibility with automated assembly.
Technical Context
This Schottky rectifier employs guard ring die construction to suppress edge breakdown and improve transient immunity. Its low VF enables high-efficiency operation in low-voltage, high-frequency switching topologies such as synchronous rectification and flyback snubberless designs.
Thermal performance is defined by RθJA = 104°C/W on FR-4 PCB with 2 oz. copper and minimum recommended pad layout. Derating begins above 25°C ambient, with rated 3.0A average current maintained only up to 100°C case temperature (TT = 100°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before avalanche; sets system-level DC bus or output voltage ceiling. |
| IO (TT=100°C) | 3.0 A - Continuous average forward current under thermal limit; defines usable output power in compact layouts. |
| VF @ 3A, 125°C | 0.61–0.67 V - Low conduction loss at elevated temperature; reduces heat generation in thermally constrained designs. |
| IFSM (8.3ms) | 80 A - Non-repetitive surge capability; withstands inrush, short-circuit, or load-dump transients without failure. |
| RθJA | 104 °C/W - Junction-to-ambient thermal resistance on standard PCB; determines required heatsinking or airflow for thermal margin. |
| IR @ 150V, 125°C | ≤20 mA - Reverse leakage at max voltage and high temperature; impacts standby power and blocking integrity in high-temp environments. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded polarity, 3.3–3.94 mm length × 4.06–4.57 mm width × 1.96–2.21 mm height, 0.093 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling or reverse polarity protection paths. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to higher-potential rail (e.g., input VBUS or output rail); blocks reverse current up to 150V. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge electric field concentration, improving surge survivability and long-term reliability under repetitive transients. |
| Low VF at high temperature | 0.61 V @ 3A, 125°C enables >92% efficiency in 5–12V output DC/DC stages without active cooling. |
| RoHS-compliant matte tin plating | Lead-free finish compatible with Pb-free reflow profiles and IPC-J-STD-020 Level 1 moisture sensitivity handling. |
| 125A peak surge rating (non-repetitive) | Exceeds JEDEC standard test condition; supports design margin against worst-case inductive kick or capacitor charging surges. |
Applications
| DC/DC Converter Output Rectification | Solar Microinverter Freewheeling |
|---|---|

FAQ
What is the maximum junction temperature for continuous operation?
The SBR3150SB-13 is rated for continuous operation up to TJ = 150°C. However, its average forward current IO is specified at TT = 100°C (case temperature), and derating is required above that point per Figure 3. Thermal design must ensure junction temperature remains ≤150°C under worst-case ambient and power dissipation conditions.
Is the SBR3150SB-13 suitable for use in automotive applications?
Yes-the device meets AEC-Q101 stress-test requirements for discrete semiconductors and is widely used in automotive body control modules and infotainment power supplies. Its 150V VRRM, 80A surge rating, and RoHS-compliant lead-free finish align with automotive qualification and environmental standards.
How does the guard ring construction improve reliability?
The guard ring die structure reduces electric field crowding at the silicon periphery, suppressing premature edge breakdown under high reverse bias or transient stress. This extends operational life in applications subject to repetitive voltage spikes, such as motor drives and inductive load switching.
Can the SBR3150SB-13 replace a standard PN rectifier in an existing design?
Yes-if the circuit operates below 150V reverse voltage and benefits from lower forward drop. However, verify reverse leakage (up to 20 mA @ 125°C) and ensure thermal design accounts for different VF vs. temperature behavior versus PN diodes, especially in high-temperature environments.
