Product details
Overview
SBR0220LP-7 from Diodes Incorporated is a 0.2A Super Barrier Rectifier (SBR®) in X1-DFN1006-2 package, designed for low-voltage, high-efficiency DC/DC conversion and reverse polarity protection. It delivers 20V peak repetitive reverse voltage, 0.38V typical forward voltage at 0.1A/25°C, and <1.3µA leakage at 20V/150°C - enabling compact, thermally stable power rail protection in space-constrained portable electronics.
For engineers reviewing the SBR0220LP-7 datasheet, SBR0220LP-7 pinout, SBR0220LP-7 application, or SBR0220LP-7 equivalent, key selection criteria include ultra-low VF at high temperature, soft-switching behavior to reduce EMI, +150°C junction rating for automotive under-hood use, and DFN1006 footprint compatibility with automated assembly on dense PCBs.
Technical Context
This SBR rectifier uses patented Super Barrier technology to achieve lower forward voltage and higher temperature stability than standard Schottky diodes, without the high reverse leakage typical of conventional Schottkys. Its 0.33V VF at 0.2A/150°C and 1.3µA IR at 20V/150°C confirm robust performance across automotive and industrial thermal profiles.
The device operates up to +150°C junction temperature with RθJA = 304°C/W on FR-4 (2oz Cu), and its soft, fast switching minimizes ringing and EMI during transient load changes in buck converter freewheel paths and USB power switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Blocks up to 20V reverse voltage, suitable for 5V–12V rail protection and USB PD input stages. |
| IF(AV) | 0.2 A - Supports continuous output current in low-power DC/DC converters and battery charging circuits. |
| VF @ 0.1A/25°C | 0.38 V - Reduces conduction loss by ~30% vs. comparable Schottkys, improving efficiency in always-on power rails. |
| IR @ 20V/150°C | 1.3 µA - Enables reliable reverse blocking in hot environments (e.g., automotive cabin modules) without thermal runaway risk. |
| TJ max | +150°C - Qualified for under-hood automotive applications per JEDEC reliability standards. |
| RθJA | 304 °C/W - Requires minimal copper area (per Diodes' recommended pad layout) for thermal management in DFN1006 footprint. |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT0220L-7 | Same SBR die, but in SOD-123FL package (2.7mm × 1.7mm); RθJA = 220°C/W; VF = 0.42V @ 0.2A/25°C. | Preferred where manual rework or visual inspection is required; less suited for ultra-dense layouts. | Select when board-level thermal mass is limited but hand-solderability or optical verification is prioritized. |
| NSR0220HT1G | Standard Schottky; VF = 0.45V @ 0.2A/25°C; IR = 100µA @ 20V/150°C - 77× higher leakage than SBR0220LP-7. | Acceptable in room-temperature consumer devices; unsuitable for automotive or extended-temperature industrial use. | Choose only if cost is primary constraint and thermal environment stays below 85°C ambient. |
Compared with SBRT0220L-7 and NSR0220HT1G, SBR0220LP-7 uniquely balances ultra-low VF, sub-µA high-temp leakage, and 1.0mm × 0.6mm footprint - making it optimal for thermally aggressive, space-constrained applications where reliability trumps marginal cost savings.

FAQ
What is the maximum allowable PCB pad size for thermal performance?
The recommended pad layout for SBR0220LP-7 specifies a 0.70mm × 0.70mm cathode thermal pad (X1 dimension) with 0.40mm × 0.30mm solder mask opening (X and G). Using this layout achieves the published RθJA of 304°C/W on 2oz FR-4; larger pads improve thermal performance but may compromise solder joint reliability due to tombstoning risk.
Is SBR0220LP-7 qualified for automotive applications?
SBR0220LP-7 is qualified to JEDEC reliability standards referenced in AEC-Q200 and manufactured in IATF 16949-certified facilities. While not AEC-Q101 stress-tested itself, its thermal, electrical, and process qualifications align with automotive-grade requirements - and Diodes offers the automotive-qualified SBR0220Q-7 variant for PPAP-controlled programs.
How does soft switching reduce EMI in buck converters?
Soft switching in SBR0220LP-7 limits di/dt during turn-off by avoiding abrupt carrier collapse, thereby suppressing high-frequency ringing above 100MHz. This eliminates the need for external RC snubbers in 1–3MHz buck converters, reducing bill-of-materials count and PCB area while meeting CISPR-32 Class B conducted emissions limits.
Can SBR0220LP-7 replace a standard Schottky in existing designs?
Yes - SBR0220LP-7 is a direct footprint replacement for X1-DFN1006-2 Schottkys (e.g., RB520S-30), offering identical mounting and soldering processes. However, its lower VF and drastically reduced high-temp leakage improve efficiency and long-term reliability, especially in thermally demanding applications where standard Schottkys exhibit thermal runaway.
