Product details
Overview
SBRFP10U45D1-13 from Diodes Incorporated is a 10A, 45V field-plated super barrier rectifier (SBR) in TO252 (DPAK) package, optimized for ultra-low forward voltage drop (0.44 V @ 10A, +25°C) and low reverse leakage (200 µA @ 45V, +25°C). It serves as a high-efficiency polarity protection diode and flyback/re-circulating diode in DC/DC converters and AC/DC adapters, enabling cooler operation and improved system reliability.
For engineers reviewing the SBRFP10U45D1-13 datasheet, SBRFP10U45D1-13 pinout, SBRFP10U45D1-13 application, or SBRFP10U45D1-13 equivalent, key selection criteria include its 190A non-repetitive surge rating, 590 mJ avalanche energy (4A, 50mH), 2°C/W junction-to-case thermal resistance, and robust TO252 thermal performance with heatsink support.
Technical Context
This SBR leverages patented Super Barrier Rectifier technology to achieve lower VF than standard Schottky diodes while maintaining superior reverse blocking stability at high temperature. Its field-plated structure enhances electric field distribution, reducing leakage drift and improving avalanche ruggedness.
The device operates across –55°C to +150°C, with verified IR stability up to 125°C (55 µA @ 45V), and supports high-frequency switching applications due to its 55 ns reverse recovery time and 450 pF junction capacitance at 45V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse voltage; defines safe DC blocking capability in polarity protection and flyback circuits. |
| IO (Avg) | 10 A - Continuous average forward current; supports high-current DC/DC output stages without forced cooling. |
| VF Max | 0.50 V @ 10A, +25°C - Ultra-low conduction loss; reduces power dissipation by ~30% vs. comparable Schottkys in 12V–24V systems. |
| IR Max | 200 µA @ 45V, +25°C - Tight leakage spec ensures minimal standby loss in always-on power rails. |
| tRR | 55 ns - Fast recovery enables use in 100–500 kHz DC/DC topologies without excessive switching loss. |
| EAS | 590 mJ @ IAS = 4A, L = 50mH - High single-pulse avalanche energy protects against inductive kickback in motor drive recirculation paths. |
| RθJC | 2 °C/W - Low junction-to-case thermal resistance allows direct PCB copper pour or heatsink mounting for sustained 10A operation. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, thermally enhanced plastic case with exposed drain pad (Pin 2). Molded compound meets UL 94V-0; terminals are matte tin, solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Forward current entry point; electrically connected to Pin 3 on PCB per datasheet requirement. |
| Pin 2 | Cathode / Drain Pad | Main current return path and primary thermal interface; must be soldered to large copper area for thermal management. |
| Pin 3 | Anode (tie to Pin 1) | Redundant anode connection; mandatory PCB tie to Pin 1 to ensure current sharing and reduce bond wire stress. |
Key Features
| Feature | Design Value |
|---|---|
| Field-plated SBR® structure | Enables 0.44 V VF at 10A while suppressing leakage rise at 125°C-critical for automotive under-hood reliability. |
| 590 mJ avalanche energy | Withstands >4A inductive transients without failure-eliminates need for external snubbers in flyback and buck-boost designs. |
| TO252 thermal performance | RθJC = 2°C/W with heatsink yields <10°C junction rise at 10A-enables compact, fanless industrial power supplies. |
| RoHS 3 & Halogen-free | Meets EU Directive 2015/863; Br+Cl <1500 ppm, Sb <1000 ppm-compliant for green consumer and medical end equipment. |
Applications
| Polarity Protection | DC/DC Converter Output |
|---|---|
Use Scenario: Reverse-voltage protection on 12V/24V input rails of industrial controllers and IoT gateways. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during battery misconnection or hot-swap events. Use Value: 0.44 V VF minimizes voltage drop and heat generation-preserves >98% input voltage at full load without heatsink. | Use Scenario: Freewheeling diode in synchronous buck converter output stage for telecom power modules. IC Role / Device Role / Timing Role: Recirculating current path during low-side switch off-time; handles peak currents up to 190A surge. Use Value: 55 ns tRR and low CJ enable stable operation at 300 kHz with <1% efficiency penalty vs. ideal diode. |
| AC/DC Adapter Secondary | Flyback Snubber Diode |

IC Role / Device Role / Timing Role: Transient voltage clamp absorbing leakage inductance energy during MOSFET turn-off. Use Value: 590 mJ EAS rating absorbs worst-case 50mH inductive spikes-replaces discrete TVS + Zener combinations with single component. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH04-M3 | 40V VRRM, 0.47V VF @ 10A, TO252, but only 300 mJ EAS | Limited to ≤40V systems; lower avalanche margin requires snubber redesign in high-inductance flyback. | Choose when 40V rating suffices and cost sensitivity outweighs surge robustness. |
| ON Semiconductor NRVB1045CTT4G | 45V VRRM, dual common-cathode configuration, 0.52V VF @ 10A, TO263 | Requires larger footprint; higher VF increases conduction loss in high-duty-cycle DC/DC outputs. | Prefer for dual-output designs needing shared cathode; avoid where thermal budget is tight. |
Compared with VS-10EWH04-M3 and NRVB1045CTT4G, SBRFP10U45D1-13 delivers superior thermal efficiency (0.44 V VF), higher avalanche resilience (590 mJ), and TO252 footprint compatibility-making it optimal for space-constrained, high-reliability 45V power rails.

FAQ
What is the maximum continuous junction temperature for SBRFP10U45D1-13?
The device is rated for TJ = –55°C to +150°C. At 10A DC with RθJA = 18°C/W (heatsink), junction temperature remains below 125°C in typical 25°C ambient conditions-well within safe operating limits. Derating curves confirm 10A is sustainable up to +85°C ambient with proper PCB copper area.
Is SBRFP10U45D1-13 qualified for automotive applications?
No AEC-Q101 qualification is stated in the datasheet. While the device operates across –55°C to +150°C and features robust avalanche performance, Diodes Incorporated explicitly notes that automotive-grade versions require PPAP-capable manufacturing and IATF 16949 certification-available only under separate part numbers with explicit AEC-Q101 marking.
Why must Pins 1 and 3 be connected on the PCB?
Pins 1 and 3 are internally bonded anode connections. The datasheet mandates external PCB tie to balance current distribution across both bond wires, prevent localized heating, and ensure rated 10A current handling. Omitting this connection risks premature bond wire failure under sustained load.
How does the field-plated structure improve reliability versus standard Schottky diodes?
The field plate redistributes electric field at the metal-semiconductor junction edge, suppressing leakage current acceleration at high temperature and voltage. This results in stable IR up to 125°C (55 µA) and eliminates thermal runaway risk-unlike conventional Schottkys, which often exhibit exponential IR increase above 100°C.
