Product details
Overview
SBR0330CW-7 from Diodes Incorporated is a 0.3A, 30V Super Barrier Rectifier in SOT323 package, featuring ultra-low reverse leakage (≤5 µA at 30V, 25°C), low forward voltage (530 mV typical at 300 mA), and soft fast switching for high-efficiency DC/DC conversion in space-constrained portable power supplies.
For engineers reviewing the SBR0330CW-7 datasheet, SBR0330CW-7 pinout, SBR0330CW-7 application, or SBR0330CW-7 equivalent, this device serves as a high-reliability, low-loss rectifier for battery-powered IoT sensors, USB-C power path management, and compact AC/DC adapter secondary-side rectification where thermal performance and leakage stability at elevated temperatures are critical.
Technical Context
This Super Barrier Rectifier replaces Schottky diodes in low-voltage, high-efficiency applications by combining lower forward voltage than standard PN diodes and significantly reduced reverse leakage versus conventional Schottkys-especially above 85°C. Its patented SBR® structure achieves VF/IR trade-off optimization without gold-doped lifetime control.
Designed for single-phase, half-wave rectification with 8.3 ms non-repetitive surge capability (1 A), it operates across –65°C to +150°C and delivers stable performance under capacitive load conditions when derated by 20% per datasheet guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 5 V–12 V output rails. |
| IF(AV) | 0.3 A - Average forward current rating; supports continuous operation in low-power SMPS outputs up to ~1.5 W. |
| VF @ 300 mA | 530 mV typ - Low conduction loss enables >94% efficiency in 3.3 V buck converter synchronous rectifier replacement. |
| IR @ 30 V, 25°C | 5 µA max - Ultra-low leakage preserves battery runtime in always-on sensor nodes and standby power stages. |
| RθJA (FR-4) | 445 °C/W - Thermal resistance on minimum pad layout; requires careful PCB copper area planning for >150 mW dissipation. |
| TJ Range | –65°C to +150°C - Enables deployment in automotive cabin modules and industrial edge controllers without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT0330WQ-7 | Same SBR architecture but AEC-Q101 qualified; 1000 h HTOL tested at 150°C. | Required for automotive body electronics; not needed for commercial-grade portable devices. | Select when ISO/TS 16949 production traceability and extended reliability validation are mandated. |
| APL3030WQ-7 | Lower IF(AV) = 0.2 A; VF = 480 mV @ 200 mA; IR = 10 µA @ 30 V, 25°C. | Suitable only for sub-1 W loads; insufficient surge rating (IFS M = 0.6 A) for peak-current-sensitive adapters. | Choose only if board space allows larger footprint and thermal budget permits higher VF-induced losses. |
Compared with SBRT0330WQ-7, SBR0330CW-7 offers identical electrical specs at lower cost and qualification overhead; versus APL3030WQ-7, it delivers 50% higher surge tolerance and 2× lower leakage-making it preferable for robust, medium-power consumer and industrial rectification.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR0330CW-7 has a specified operating junction temperature range of –65°C to +150°C. For continuous DC operation, the absolute maximum TJ is +150°C. Derating is required above +125°C ambient depending on PCB copper area and airflow; thermal resistance on FR-4 is 445°C/W with minimum recommended pads.
Can SBR0330CW-7 replace a standard Schottky diode in a 5 V buck converter output stage?
Yes-it is designed as a direct upgrade: same 30 V VRRM and SOT323 footprint, but with lower IR at high temperature and comparable VF. At 300 mA and +85°C, its leakage remains ≤18 µA versus >100 µA for typical Schottkys, reducing standby loss significantly.
Is the SOT323 package lead-free and RoHS compliant?
Yes-the SBR0330CW-7 uses matte tin annealed over Alloy 42 leadframe and meets EU RoHS Directive 2011/65/EU. It is also halogen- and antimony-free ("Green"), with Br+Cl < 1500 ppm and Sb < 1000 ppm, certified per Diodes Incorporated's AP02001 and AP02002 standards.
Does the dual-anode configuration require separate PCB traces?
No-Anode 1 and Anode 2 are internally shorted per the top-view diagram and mechanical drawing. Both pins must be soldered to the same net (e.g., input voltage rail); splitting traces provides no electrical benefit and risks uneven current sharing or thermal stress.
