Product details
Overview
SBRT15M50AP5-7 from Diodes Incorporated is a 50 V, 15 A Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, featuring 0.54 V max forward voltage at 15 A/25°C, 0.15 mA max reverse leakage at 50 V/25°C, and 2 °C/W junction-to-case thermal resistance. It serves as a high-efficiency, low-leakage rectifier or freewheeling diode in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the SBRT15M50AP5-7 datasheet, SBRT15M50AP5-7 pinout, SBRT15M50AP5-7 application, or SBRT15M50AP5-7 equivalent, key selection criteria include high-temperature IR stability, ultra-low profile (<1.1 mm), thermally optimized lead-frame design, and RoHS-compliant green packaging for space-constrained power stages.
Technical Context
This Trench SBR uses proprietary trench-based super barrier technology to achieve lower forward voltage and superior reverse leakage performance versus conventional Schottky and standard PN rectifiers. Its 50 V VRRM rating targets secondary-side synchronous rectification and input rectification in sub-50 V systems.
The POWERDI®5 package integrates a thermally efficient copper lead-frame with bottom-side heat sink capability, enabling 15 A continuous conduction with RθJC = 2 °C/W and RθJL = 4 °C/W - critical for high-density, thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum blocking voltage for secondary-side rectification in ≤50 V output supplies. |
| IO (AV) | 15 A - Continuous average forward current at TA = 25°C with 1-inch² FR4 copper pad, supporting high-current adapter outputs. |
| VF (MAX) | 0.54 V @ 15 A, 25°C - Low conduction loss enabling >95% efficiency in 12–24 V DC/DC outputs. |
| IR (MAX) | 0.15 mA @ 50 V, 25°C - Stable leakage under full-rated voltage, minimizing standby power loss. |
| RθJC | 2 °C/W - Enables direct thermal coupling to PCB copper, reducing junction temperature rise by ~30°C vs. SO-8 equivalents. |
| Junction Temp | −55 to +150°C - Supports operation in automotive cabin and industrial ambient environments without derating. |
Pinout & Package
Package: POWERDI®5 - surface-mount, thermally enhanced, 2-pin lead-frame package with bottom-side thermal pad; 1.1 mm max height, 4.0 mm × 6.6 mm footprint; UL 94V-0 molded compound; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; electrically connected to PCB anode trace and internal die anode bond. |
| Right Pin | Cathode | Current return path and thermal interface; directly bonded to internal cathode metallization and external PCB copper pour. |
| Bottom Surface | Thermal Pad / Cathode Extension | Integral part of cathode terminal; must be soldered to ≥1-inch² copper area for rated 15 A operation and thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Trench SBR Technology | Combines low VF of Schottky with high-temperature IR stability of PN diodes - eliminates trade-off between conduction loss and leakage. |
| POWERDI®5 Thermal Performance | RθJC = 2 °C/W enables 15 A operation with <25°C junction rise on standard FR4 - no heatsink required in most applications. |
| Ultra-Low Profile | 1.1 mm max height allows integration into <1.6 mm total board thickness designs, e.g., slim wall adapters and USB-PD modules. |
| Green Compliance | Halogen- and antimony-free, RoHS-compliant, lead-free finish - meets IPC-1752A Class 2 reporting and EU environmental mandates. |
Applications
| AC/DC Adapters & Chargers | DC/DC Converters |
|---|---|
Use Scenario: Secondary-side rectification in 12–24 V, >10 W wall adapters with tight height constraints. IC Role / Device Role / Timing Role: High-efficiency output rectifier replacing Schottky diodes to reduce conduction loss and improve thermal margin. Use Value: 0.54 V VF at 15 A lowers dissipation by ~0.8 W vs. typical 0.75 V Schottky, enabling smaller heatsinks or higher power density. |
Use Scenario: Freewheeling diode in buck converter output stage for telecom and server POL supplies. IC Role / Device Role / Timing Role: Fast-recovery, low-leakage flyback path during high-frequency (300–1 MHz) switching cycles. Use Value: 0.15 mA IR at 25°C and stable leakage up to 125°C minimizes standby current and improves light-load efficiency. |
| Polarity Protection | Industrial Power Supplies |
Use Scenario: Reverse-voltage protection at main DC input of programmable logic controllers and sensor nodes. IC Role / Device Role / Timing Role: Series-connected input protection diode ensuring system survival during accidental battery reversal. Use Value: 50 V VRRM and 290 A IFSM withstand transient surges and sustained reverse faults without latch-up or thermal runaway. |
Use Scenario: Output rectification in DIN-rail mounted 24/48 V industrial PSUs operating continuously at 60–85°C ambient. IC Role / Device Role / Timing Role: Primary output rectifier delivering stable 15 A with minimal thermal drift across temperature. Use Value: IR increases only 300× (to 45 mA) at 125°C - far less than Schottky alternatives - preserving system reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15M50CT-13 | Same die, TO-220AC package - higher RθJA (40 °C/W), requires heatsink for 15 A. | Suitable where mechanical mounting and heatsinking are available; unsuitable for ultra-thin PCBs. | Select when thermal mass and airflow allow TO-220 mounting; avoid when board height <1.6 mm. |
| SS15P5 | 15 A, 50 V Schottky in SMA package - VF ≈ 0.52 V but IR = 1.5 mA @ 25°C, rising to >100 mA @ 125°C. | Better for cost-sensitive, low-temp applications; fails leakage-critical high-temp use cases. | Prefer only in ambient <60°C environments; reject for industrial or automotive under-hood deployments. |
Compared with SBRT15M50CT-13 and SS15P5, the SBRT15M50AP5-7 uniquely delivers 15 A capability in <1.1 mm height with IR stability up to 150°C - making it the sole choice for thermally dense, high-reliability, low-profile power conversion.

FAQ
What is the maximum continuous forward current for SBRT15M50AP5-7 at 85°C ambient?
At TA = 85°C with a 1-inch² copper pad on FR4, the SBRT15M50AP5-7 supports 10.5 A continuous forward current, per Figure 4's derating curve. This reflects a linear reduction from 15 A at 25°C due to thermal resistance limits and junction temperature ceiling of 150°C.
Does SBRT15M50AP5-7 require a heatsink for 15 A operation?
No heatsink is required. With its RθJC = 2 °C/W and bottom-side thermal pad soldered to ≥1-inch² copper, the device achieves safe junction temperatures at 15 A and 25°C ambient. Heatsinking becomes unnecessary unless ambient exceeds 60°C or PCB copper area is reduced below specification.
How does the reverse leakage compare between 25°C and 125°C?
IR is 0.15 mA max at 50 V and 25°C, rising to 45 mA max at 50 V and 125°C - a 300× increase. This remains significantly lower than Schottky alternatives (e.g., SS15P5 reaches >100 mA at 125°C), confirming superior high-temperature stability.
Is SBRT15M50AP5-7 compatible with lead-free reflow profiles?
Yes. The device is qualified for standard JEDEC J-STD-020 Level 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. Its lead-free finish and green molding compound comply with IPC/JEDEC standards for Pb-free assembly processes.
