Product details
Overview
SBRT15U100SP5-13 from Diodes Incorporated is a 15A, 100V Trench Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring ultra-low forward voltage (0.7 V max @ 15 A, +25°C), low reverse leakage (0.20 mA max @ 100 V, +25°C), and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or polarity protection diode in DC/DC converters and motor drive power stages.
For engineers reviewing the SBRT15U100SP5-13 datasheet, SBRT15U100SP5-13 pinout, SBRT15U100SP5-13 application, or SBRT15U100SP5-13 equivalent, key selection criteria include thermal resistance (RθJC = 1 °C/W), junction-to-case cooling capability, high-temperature reverse leakage stability (≤30 µA @ 125°C), and compact 1.1 mm profile for space-constrained PCB layouts.
Technical Context
This SBR rectifier employs patented trench-based super barrier architecture to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability-unlike conventional Schottkys, it avoids thermal runaway above 100°C. Its structure enables simultaneous optimization of forward conduction loss and reverse blocking robustness.
The PowerDI5 package integrates a thermally enhanced bottom-side heat sink with dual-pin anode/cathode terminals electrically connected at PCB level. This configuration supports high-current handling (15 A avg, 250 A surge) with minimal thermal impedance (RθJA = 15 °C/W with heatsink).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe DC blocking capability in 12–48 V bus systems. |
| IO (avg) | 15 A - Continuous average forward current rating at TA = +25°C; derates to ~8 A at TC = +125°C per Figure 4. |
| VF (max) | 0.70 V @ 15 A, +25°C - Enables <10.5 W conduction loss at full load; critical for efficiency in high-current buck or flyback outputs. |
| IR (max) | 0.20 mA @ 100 V, +25°C - Low leakage preserves standby power integrity; remains ≤30 µA up to +125°C for thermal margin. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct mounting to copper pour or heatsink for high-power dissipation control. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive under-hood applications including temperature cycling and HTRB. |
Pinout & Package
Package: PowerDI5 - Surface-mount, thermally optimized plastic package with exposed copper heat sink on bottom side; 1.1 mm maximum height, 3.966 mm × 6.504 mm footprint; RoHS-compliant, halogen-free, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; must be soldered to PCB copper pour for thermal conduction and electrical connection. |
| Right Pin | Cathode | Current exit terminal; electrically tied to left pin via PCB trace or plane to complete low-inductance path. |
| Bottom Side (Exposed Pad) | Thermal Heat Sink / Cathode Tie | Electrically connected to cathode; provides primary thermal path to PCB; requires solder mask defined thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.56 V typ @ 15 A, +25°C - Reduces I²R losses by >30% vs. standard FRD in 12 V input converters. |
| Trench SBR® Technology | Patented barrier engineering - Delivers Schottky-like VF with PN-junction-level reverse leakage control up to +150°C. |
| PowerDI5 Thermal Efficiency | RθJC = 1 °C/W - Enables >2× higher power density than SO-8 or TO-252 equivalents at same current rating. |
| Thin Profile | Max height 1.1 mm - Fits beneath low-clearance shields or connectors in automotive ADAS ECUs and infotainment modules. |
Applications
| Automotive DC/DC Converters | Industrial Motor Drive Freewheeling |
|---|---|
Use Scenario: High-efficiency 12 V → 3.3 V/5 V buck converter in body control module (BCM) with ambient up to +105°C. IC Role / Device Role / Timing Role: Output rectifier replacing Schottky diode to reduce conduction loss and eliminate thermal runaway risk. Use Value: Cuts diode power loss by 1.2 W at 10 A load, lowering case temperature rise by ~12°C and extending system lifetime. | Use Scenario: Flyback snubber and freewheeling path in 24 V BLDC gate driver power supply. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode across inductive load during PWM off-time. Use Value: 0.7 V VF minimizes energy dissipation during flyback cycle; stable IR prevents thermal drift in enclosed enclosures. |

Use Scenario: Secondary-side synchronous rectification assist in 45 W USB-C PD adapter with tight thermal budget. IC Role / Device Role / Timing Role: Auxiliary rectifier paralleled with SR MOSFET to handle reverse recovery tail current. Use Value: Low VF and soft recovery reduce EMI generation and improve efficiency over 90% at full load. | Use Scenario: Input polarity guard in -48 V telecom rectifier board where reverse connection must be blocked without fuse blow. IC Role / Device Role / Timing Role: Series-connected reverse-blocking diode protecting downstream DC-DC modules. Use Value: 100 V VRRM and AEC-Q101 qualification ensure fail-safe operation under sustained reverse bias and thermal stress. |
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 |
|---|---|---|---|
| SBRT15U100CT-13 | Same die, TO-220AC package - RθJC = 1.5 °C/W, taller (9.1 mm), through-hole mount. | Suitable for legacy through-hole designs or forced-air-cooled industrial supplies; lacks surface-mount thermal pad. | Choose when mechanical mounting or airflow cooling dominates over PCB space constraints. |
| MBR15100CTG | Standard Schottky, TO-220AB - VF ≈ 0.85 V @ 15 A, IR rises to >1 mA at +125°C. | Acceptable in lower-temp environments (<85°C ambient); higher leakage risks thermal instability in sealed enclosures. | Choose only if cost sensitivity outweighs thermal reliability requirements and peak temperature stays below 85°C. |
Compared with SBRT15U100CT-13 and MBR15100CTG, the SBRT15U100SP5-13 delivers superior thermal performance in space-limited SMT designs, maintains leakage stability at elevated temperatures, and enables thinner end-equipment form factors-making it optimal for modern automotive and portable power systems.

FAQ
What is the maximum junction temperature for continuous operation?
The SBRT15U100SP5-13 has an operating junction temperature range of –65°C to +150°C. For reliable long-term operation, maximum continuous junction temperature should be limited to +150°C, with derating applied above +125°C per Figure 4. Thermal design must ensure RθJA and power dissipation keep TJ within this limit under worst-case ambient and load conditions.
Is the PowerDI5 package lead-free and RoHS compliant?
Yes. The SBRT15U100SP5-13 features a lead-free finish and is fully compliant with EU RoHS Directive 2011/65/EU. It also meets Diodes Incorporated's "Green" definition: <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony, verified per JESD22-A112 test standards.
How does the SBR® technology differ from standard Schottky diodes?
SBR® uses a trench-isolated super barrier structure that combines low forward voltage (comparable to Schottky) with dramatically reduced high-temperature reverse leakage-unlike Schottky diodes, which suffer exponential IR increase above 85°C. This eliminates thermal runaway risk in sealed or high-ambient environments.
Can SBRT15U100SP5-13 be used in synchronous rectification topologies?
No-it is a unidirectional rectifier, not a synchronous MOSFET controller or driver. However, it is frequently used alongside synchronous rectifiers as a clamp or auxiliary path to manage reverse recovery energy and improve EMI performance in high-frequency flyback or LLC converters.
