Product details
Overview
SBRT15U50SP5-7D from Diodes Incorporated is a 15A, 50V Trench Super Barrier Rectifier (SBR) in POWERDI®5 package, featuring ultra-low 0.47V max forward voltage at 15A/25°C and 0.5mA max reverse leakage at 50V/125°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC-DC adapters and DC-DC converters.
For engineers reviewing the SBRT15U50SP5-7D datasheet, SBRT15U50SP5-7D pinout, SBRT15U50SP5-7D application, or SBRT15U50SP5-7D equivalent, key selection criteria include thermal resistance (RθJL = 4°C/W), low-profile 1.1mm height, AEC-Q101 qualification, RoHS/Green compliance, and stable IR performance up to +150°C junction temperature.
Technical Context
This TrenchSBR uses advanced trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability-unlike conventional Schottkys, it avoids catastrophic thermal runaway at elevated temperatures. Its RθJL of 4°C/W enables efficient heat transfer to the cathode pad, supporting high-current operation on thermally enhanced PCBs.
The POWERDI®5 package integrates a low-inductance, dual-cathode terminal structure optimized for high-frequency switching topologies. With CJ = 440pF at 25V, it supports fast transient response in synchronous rectification and buck converter freewheeling paths without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; ensures safe operation in 36V nominal DC-DC outputs and 50V clamp circuits. |
| IO (AV) | 15 A - Average rectified current rating at TA=25°C with recommended PCB layout; supports >10W adapter output stages. |
| VF (MAX) | 0.47 V @ 15A, 25°C - Ultra-low forward drop reduces conduction loss by ~30% vs. standard Schottky alternatives at same current. |
| IR (MAX) | 0.5 mA @ 50V, 125°C - Stable leakage enables reliable operation in automotive under-hood environments without thermal runaway. |
| RθJL | 4 °C/W - Junction-to-lead thermal resistance; allows direct thermal coupling to copper pour for high-power density designs. |
| CJ | 440 pF @ 25V - Low junction capacitance minimizes switching loss and EMI in high-frequency (>300kHz) converters. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to switch node or input rail; designed for low-inductance routing in high-dI/dt applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U50SP5-13D | Identical die and package; differs only in tape-and-reel quantity (5,000 vs. 1,500 units) and reel size (13″ vs. 7″). | No functional difference; selected based on production volume and line feed requirements. | Choose -13D for high-volume automated assembly; -7D suits low-to-mid volume or prototyping runs. |
| SBRT10U50SP5-7D | Same POWERDI®5 package and 50V rating, but rated for 10A average current and lower VF (0.45V max @ 10A). | Lower current capability limits use to ≤10W adapters or 12V→3.3V converters with <10A loads. | Select when thermal budget or cost constraints justify reduced current rating without sacrificing VF or IR performance. |
Compared with SBRT10U50SP5-7D, the SBRT15U50SP5-7D delivers 50% higher current capacity with identical thermal and electrical behavior per ampere, while the -13D variant offers no electrical distinction-only packaging logistics differ.

FAQ
What is the maximum junction temperature rating for SBRT15U50SP5-7D?
The SBRT15U50SP5-7D has an operating junction temperature range of –65°C to +150°C, validated per AEC-Q101 stress testing. Its thermal design supports sustained operation at TJ = 150°C when mounted on aluminum substrate PCBs with heatsink, as confirmed by RθJL = 4°C/W and IR stability data up to 125°C.
Is SBRT15U50SP5-7D pin-compatible with standard Schottky diodes in POWERDI®5?
Yes-SBRT15U50SP5-7D shares identical POWERDI®5 mechanical dimensions, pad layout (per AP02001), and terminal configuration (anode + dual cathode) with industry-standard Schottky diodes in the same package. No PCB redesign is required for drop-in replacement where VF and IR improvements are beneficial.
Does SBRT15U50SP5-7D require a thermal pad connection for rated current operation?
Yes-the exposed cathode tab must be soldered to a minimum 30mm × 30mm, 2oz copper pad (per datasheet Note 7) to achieve the rated 15A IO and maintain TJ ≤ 150°C. Without this thermal pad, RθJA rises to 101°C/W, limiting continuous current to ~4.5A on standard FR-4.
How does SBRT15U50SP5-7D differ from conventional Schottky rectifiers in reliability?
Unlike conventional Schottkys, SBRT15U50SP5-7D uses trench super barrier technology to suppress thermal runaway-its IR increases only 3.5× from 25°C to 125°C (vs. >100× for typical Schottkys). This enables robust operation in automotive and industrial environments where ambient temperatures exceed 85°C without derating.
