Product details
Overview
SBRT20U100SLP from Diodes Incorporated is a 20A, 100V trench super barrier rectifier (SBR®) in PowerDI5060-8 package, featuring 0.70 V max forward voltage at 20 A/25°C, 0.3 mA max reverse leakage at 100 V/25°C, and 2 °C/W junction-to-case thermal resistance. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters and AC-DC adapters operating up to +150°C.
For engineers reviewing the SBRT20U100SLP datasheet, SBRT20U100SLP pinout, SBRT20U100SLP application, or SBRT20U100SLP equivalent, key selection criteria include ultra-low VF stability across temperature, <0.3 mA IR at 125°C, 180 A non-repetitive surge rating, and thermally optimized 8-pin PowerDI5060-8 footprint for high-power density designs.
Technical Context
This SBR device uses patented trench-based super barrier technology to achieve lower forward voltage than Schottky diodes while maintaining superior high-temperature reverse leakage performance versus standard PN rectifiers. Its 100 V VRRM and 20 A IO rating target secondary-side rectification in isolated flyback and LLC topologies.
The PowerDI5060-8 package integrates eight terminals-four anode and four cathode leads-enabling parallel current paths and low-inductance layout. Thermal design leverages 2 °C/W RθJC into a heatsink and 9 °C/W RθJA on 2 oz Cu board with auxiliary heatsink, supporting continuous 20 A operation at ≤85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands repetitive reverse voltage up to 100 V without breakdown in rectifier or blocking roles. |
| IO (AV) | 20 A - Continuous average forward current capability at TC = 115°C per JEDEC test condition. |
| VF (max) | 0.70 V @ 20 A, 25°C - Enables >92% efficiency in 12 V output DC-DC stages with minimal conduction loss. |
| IR (max) | 0.3 mA @ 100 V, 25°C - Ensures stable blocking behavior and low standby power in energy-sensitive adapters. |
| RθJC | 2 °C/W - Allows direct thermal coupling to heatsink for sustained 20 A operation without derating below 115°C case temp. |
| IFSM | 180 A @ 8.3 ms - Survives inrush and transient overcurrent events in AC-DC input stages and motor drive freewheel paths. |
| TJ Range | −55°C to +150°C - Supports industrial and extended-temperature applications including automotive under-hood power supplies. |
Pinout & Package
Package: PowerDI5060-8 - Thermally enhanced 8-terminal surface-mount package with 1.1 mm max profile, matte tin-plated copper leadframe, and UL 94V-0 green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Anode | Four paralleled anode terminals reduce series resistance and inductance; require symmetric PCB routing for current sharing. |
| C1–C4 | Cathode | Four paralleled cathode terminals provide low-impedance return path; connect directly to ground/power plane for thermal and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.64 V typ @ 20 A, 125°C - Reduces conduction loss by ≥15% vs. comparable Schottky diodes at elevated temperature. |
| High-temp IR stability | 80 µA @ 100 V, 150°C - Prevents thermal runaway in sealed enclosures where ambient exceeds 85°C. |
| Thin profile | 1.1 mm max height - Enables use in space-constrained USB-C PD adapters and slim LED drivers. |
| SBR® trench architecture | Patented super barrier structure - Combines Schottky-like VF with PN-like leakage and surge robustness. |
| Green construction | Halogen- and antimony-free, RoHS 3 compliant - Meets IPC-1752A material declaration and automotive ELV requirements. |
Applications
| Server VRM Output Rectification | USB-C PD Adapter Secondary Side |
|---|---|
Use Scenario: High-current, high-frequency synchronous rectification replacement in 48 V → 12 V server point-of-load converters. IC Role / Device Role / Timing Role: Primary output rectifier handling 20 A DC with <100 ns switching transitions.

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-20BQ100-M3/45 | 100 V, 20 A Schottky; VF = 0.62 V @ 20 A, 25°C but IR = 1.5 mA @ 125°C. | Higher leakage limits use in sealed, high-ambient environments; unsuitable above 105°C ambient. | Select only if board-level cooling maintains TJ < 110°C and leakage sensitivity is low. |
| ON Semiconductor NRVB20100CT | 100 V, 20 A dual common-cathode Schottky; VF = 0.68 V @ 20 A, 25°C; IR = 0.5 mA @ 125°C. | Requires dual-diode layout; higher IR increases standby loss in energy-critical adapters. | Prefer only when dual-cathode topology matches existing PCB; otherwise SBRT20U100SLP offers better thermal and leakage performance. |
Compared with VS-20BQ100-M3/45 and NRVB20100CT, SBRT20U100SLP delivers 75% lower IR at 125°C and integrated 8-terminal thermal path-critical for unventilated industrial and automotive power supplies where thermal runaway risk dominates reliability.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBRT20U100SLP has a rated TJ range of −55°C to +150°C. For continuous 20 A operation, junction temperature must be maintained ≤150°C using appropriate heatsinking. Derating begins at TC = 115°C per the datasheet's Figure 5, with 0 A current allowed at TC = 150°C.
Is SBRT20U100SLP suitable for automotive applications?
Yes-the base part meets JEDEC high-reliability standards and is referenced in Diodes' automotive-grade portfolio. The automotive-qualified version SBRT20U100SLPQ is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities for infotainment and body electronics power supplies.
How does the PowerDI5060-8 package improve thermal performance over SO-8 or TO-252?
PowerDI5060-8 provides 2 °C/W RθJC-nearly 3× better than SO-8 (≈5.5 °C/W) and 2.5× better than TO-252 (≈5 °C/W)-due to its exposed copper thermal pad and eight paralleled terminals. This enables 20 A conduction with smaller heatsinks or no external heatsink at moderate ambient temperatures.
Can SBRT20U100SLP replace a standard fast recovery diode in a PFC boost stage?
No-it is not rated for PFC boost applications. Its 100 V VRRM and SBR architecture are optimized for low-voltage secondary-side rectification, not 400 V+ boost diode operation. Use Diodes' FRED Pt® or Hyperfast series (e.g., DF08S200) for PFC stages requiring >600 V VRRM and soft recovery.
