Product details
Overview
SBR0230T5-7 from Diodes Incorporated is a 0.2A Super Barrier Rectifier (SBR®) optimized for high-efficiency, low-loss DC-DC conversion and freewheeling applications. It features a 30V peak repetitive reverse voltage (VRRM), maximum forward voltage of 0.61V at 0.2A/25°C, 2µA max reverse leakage at 30V/25°C, 5ns reverse recovery time (trr), and operates up to +150°C junction temperature - deployed in compact power supplies and automotive-grade auxiliary rails.
For engineers reviewing the SBR0230T5-7 datasheet, SBR0230T5-7 pinout, SBR0230T5-7 application, or SBR0230T5-7 equivalent, key selection criteria include its ultra-low VF in SOD-523 package, soft-switching behavior for EMI reduction, JEDEC-qualified reliability, and suitability for space-constrained 3.3V/5V buck converter outputs and reverse polarity protection circuits.
Technical Context
This SBR rectifier employs Diodes' patented super barrier architecture - a planar Schottky-like structure with enhanced avalanche ruggedness over conventional Schottkys. It delivers soft reverse recovery (trr = 5ns) and stable VF across temperature, enabling efficient operation in high-frequency switching topologies without snubber networks.
Its 480°C/W junction-to-ambient thermal resistance reflects the SOD-523 package's minimal copper pad footprint, requiring strict adherence to recommended FR-4 layout (2 oz Cu). The device sustains 5A non-repetitive surge current (8.3ms half-sine), supporting transient load dump tolerance in automotive auxiliary systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Blocks up to 30V reverse bias without breakdown; suitable for 24V system inputs with margin. |
| IO | 0.2 A - Continuous average forward current rating; defines usable output capacity in low-power SMPS. |
| VF (max) | 0.61 V @ 0.2A/25°C - Low conduction loss enables >92% efficiency in 3.3V buck stages at light-to-moderate loads. |
| IR (max) | 2 µA @ 30V/25°C - Minimal leakage preserves battery life in always-on standby circuits. |
| trr | 5 ns - Fast, soft recovery reduces switching noise and eliminates need for RC snubbers in 1–3 MHz converters. |
| TJ range | −65°C to +150°C - Enables deployment in under-hood automotive modules and industrial edge controllers. |
Pinout & Package
Package: SOD-523 - ultra-miniature surface-mount plastic case (0.85 × 1.25 mm, 0.17 mm height), cathode-indicated by band, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switch node (e.g., buck converter high-side FET drain); must minimize trace inductance. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; polarity band identifies this terminal - critical for reverse polarity protection wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-speed with silicon-diode-level avalanche ruggedness (no catastrophic failure under VR transients). |
| Soft, fast switching | 5ns trr with low di/dt-induced ringing - reduces EMI filter component count in CISPR-22-compliant designs. |
| +150°C operating junction | Enables placement near hot components (e.g., power inductors, MOSFETs) without derating in sealed enclosures. |
| Lead-free & Halogen-free | Meets RoHS 3 (2015/863/EU) and automotive "Green" requirements (<900ppm Br+Cl, <1000ppm Sb). |
Applications
| DC-DC Buck Converter Output | Reverse Polarity Protection |
|---|---|
Use Scenario: Secondary-side rectification in 3.3V/5V synchronous or asynchronous buck regulators powering MCU cores or sensors. IC Role / Device Role: Freewheeling diode conducting during low-side FET off-time; clamps inductive kickback. Use Value: 0.61V VF minimizes conduction loss at 0.2A, improving light-load efficiency by ~3% vs. standard Schottky alternatives. |
Use Scenario: Input protection for USB-C PD adapters, battery management ICs, or field-deployable IoT nodes. IC Role / Device Role: Series-blocking diode placed between connector and system rail; conducts only when polarity is correct. Use Value: 2µA IR at 25°C ensures <1µW standby loss - critical for multi-year battery life in coin-cell-powered devices. |
| Automotive Body Control Module | Low-Power SMPS Auxiliary Rail |
Use Scenario: Power path control in 12V accessory circuits (e.g., door lock actuators, LED interior lighting). IC Role / Device Role: Reverse voltage clamp during load dump events; absorbs energy via controlled avalanche. Use Value: Superior reverse avalanche capability allows safe operation without external TVS, reducing BOM count in AEC-Q200-aligned designs. |
Use Scenario: Standby 3.3V rail generation from main 12V/24V bus in industrial HMIs and PLC I/O modules. IC Role / Device Role: Output rectifier in flyback or buck-derived auxiliary supply; handles intermittent 100mA loads. Use Value: SOD-523 footprint saves >60% board area vs. SOD-123, enabling dense multi-rail power architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT0230T5G-7 | Same electrical specs; uses different leadframe alloy (copper vs. Alloy 42) and matte tin finish per J-STD-020. | Identical thermal and electrical performance; validated for same automotive PPAP flow. | Select if sourcing requires alternate qualified manufacturing line or specific plating compliance documentation. |
| RB520S-30T5G | 0.2A Schottky with 0.33V VF (typ) but higher IR (100µA @ 30V) and no avalanche rating. | Limited to non-automotive, non-transient-prone applications due to lack of rugged reverse recovery. | Choose only for cost-sensitive consumer applications where leakage and surge immunity are non-critical. |
Compared with SBRT0230T5G-7, SBR0230T5-7 offers identical performance with differentiated traceability for Alloy 42 leadframe sourcing; versus RB520S-30T5G, it trades slightly higher VF for robust avalanche survival and 50× lower leakage - essential for automotive and long-life battery systems.

FAQ
What is the maximum allowable PCB pad temperature during reflow for SBR0230T5-7?
The SOD-523 package is rated for standard lead-free reflow profiles (J-STD-020, Level 1). Peak temperature must not exceed 260°C for ≤30 seconds, with ramp-up rate ≤3°C/s. Exceeding these limits risks delamination or solder joint fracture due to thermal expansion mismatch between the 0.17mm-thick molded case and Alloy 42 leadframe.
Does SBR0230T5-7 require a heatsink in typical 0.2A operation?
No heatsink is required. At 0.2A and 0.61V VF, power dissipation is 122mW. With RθJA = 480°C/W and 25°C ambient, junction temperature rise is ~58°C - well within the −65°C to +150°C range. Thermal performance depends entirely on adhering to the recommended 2 oz Cu pad layout (X=0.60mm, Y=0.70mm).
Can SBR0230T5-7 be used in place of a standard Schottky diode like 1N5817?
Yes, but only in low-current (≤0.2A), low-VR (≤30V) applications where its superior avalanche capability and soft recovery provide value. It is not a drop-in replacement for 1N5817 in 1A/20V designs - its IO rating is one-fifth lower, and its SOD-523 footprint is incompatible with DO-41 pads.
Is SBR0230T5-7 qualified for automotive use per AEC-Q200?
No - SBR0230T5-7 is an industrial-grade part qualified to JEDEC standards and high-reliability requirements, but not AEC-Q200. For automotive applications, Diodes specifies Q-suffix variants (e.g., SBR0230Q5-7), which undergo additional stress testing, PPAP documentation, and IATF 16949 manufacturing controls.
