Product details
Overview
SBR1U200P1Q from Diodes Incorporated is a 1A Super Barrier Rectifier (SBR®) in PowerDI123 package, rated for 200V peak repetitive reverse voltage, 0.82V max forward voltage at 1A/25°C, and 50µA max reverse leakage at 200V/25°C. It serves as a high-efficiency, soft-switching rectifier in automotive-grade DC-DC converters and flyback power supplies.
For engineers reviewing the SBR1U200P1Q datasheet, SBR1U200P1Q pinout, SBR1U200P1Q application, or SBR1U200P1Q equivalent, key selection criteria include its AEC-Q101 qualification, 40A non-repetitive surge rating, 25ns reverse recovery time, and thermal stability up to +175°C junction temperature.
Technical Context
The SBR1U200P1Q employs patented Super Barrier Rectifier technology to achieve ultra-low VF while maintaining low IR and robust avalanche energy handling (20mJ). Its interlocking clip design enhances surge current capability beyond standard Schottky or PN diodes.
It operates across -65°C to +175°C with RθJA = 140°C/W on FR-4 PCB, and exhibits soft, fast switching behavior critical for EMI-sensitive SMPS designs. Junction capacitance is 37pF at 4V reverse bias, supporting high-frequency rectification without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum blocking voltage before breakdown; enables use in 12V–48V automotive input stages with safety margin. |
| IO | 1.0 A - Average rectified output current; supports continuous operation in compact 1W–2W power rails. |
| VF Max | 0.82 V @ 1A/25°C - Low conduction loss improves efficiency in high-duty-cycle converters. |
| IR Max | 50 µA @ 200V/25°C - Minimal leakage preserves battery standby life in always-on automotive modules. |
| tRR | 25 ns - Fast, soft recovery reduces switching noise and snubber losses in 100–500kHz SMPS. |
| EAS | 20 mJ - Avalanche energy rating allows safe clamping of inductive transients in flyback and boost topologies. |
| TJ Range | -65°C to +175°C - Full AEC-Q101 temperature compliance for under-hood and engine-control applications. |
Pinout & Package
Package: PowerDI123 - surface-mount, single-diode configuration with cathode band polarity indicator, matte tin-plated copper leadframe, and UL 94V-0 molded plastic body (0.018g weight).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to source side (e.g., transformer secondary or switch node); accepts up to 40A surge. |
| Cathode | Output current exit point | Delivers rectified output to filter capacitor/load; marked by visible cathode band on package top. |
| Case / Exposed Pad | Thermal path only (not electrically connected) | Provides mechanical anchoring and thermal dissipation; must be soldered to PCB copper pour per Diodes' recommended pad layout. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines Schottky-like VF with PN-like IR and avalanche ruggedness-enables higher temperature reliability than standard Schottkys. |
| Interlocking Clip Design | Increases IFSM to 40A (8.3ms sine), enabling robustness against load dump and cold-crank surges in automotive systems. |
| AEC-Q101 Qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing-supports Tier-1 BOM inclusion without requalification. |
| Soft, Fast Switching | 25ns tRR with controlled recovery waveform minimizes EMI generation and eliminates need for RC snubbers in many designs. |
| Green, Halogen-Free | Meets RoHS 3 and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb)-complies with EU automotive environmental mandates. |
Applications
| Automotive DC-DC Converters | Flyback Power Supplies |
|---|---|
Use Scenario: Secondary-side rectification in 12V-to-5V/3.3V buck-derived isolated converters for ADAS ECUs and infotainment head units. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier replacement with lower VF than MOSFETs at sub-1A loads. Use Value: Reduces conduction loss by ~15% vs. standard Schottky diodes at 125°C, extending thermal margin in sealed enclosures. | Use Scenario: Output rectifier in 5W–10W offline flyback adapters for telematics gateways and body control modules. IC Role / Device Role / Timing Role: Primary-side clamp-assisted rectifier with soft recovery to suppress ringing-induced EMI. Use Value: Eliminates need for external snubber components due to 25ns tRR and low CJ (37pF), simplifying layout and reducing BOM count. |
| Reverse Polarity Protection | Blocking Diodes in Battery Systems |
Use Scenario: Input protection in 24V commercial vehicle telematics units exposed to accidental battery reversal during service. IC Role / Device Role / Timing Role: Series-blocking diode placed between battery connector and main regulator IC. Use Value: Withstands 40A surge and maintains <50µA leakage at 25°C, ensuring minimal quiescent drain during long-term parking. | Use Scenario: Isolation diode between dual LiFePO₄ battery banks in off-grid EV auxiliary power systems. IC Role / Device Role / Timing Role: Prevents backfeed and cross-discharge between parallel battery strings during charge/discharge cycles. Use Value: Stable VF drift <±5mV over -40°C to +125°C ensures predictable voltage drop and state-of-charge accuracy across wide ambient range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1U200P1Q | Same die, enhanced surge rating (IFS M = 50A), identical VF/IR/tRR specs | Targeted for higher-reliability industrial motor drives requiring extended surge margin | Select when system-level surge testing exceeds 40A or requires MIL-STD-1275E compliance |
| SD103CWS-7 | Standard Schottky, VF = 0.45V typ but IR = 500µA @ 20V; no AEC-Q101 or 175°C rating | Consumer-grade USB-C PD adapters where cost > automotive qualification | Choose only for non-automotive, <85°C ambient applications with tight VF budget and relaxed leakage requirements |
Compared with SBRT1U200P1Q, the SBR1U200P1Q offers sufficient surge margin for most AEC-Q101-compliant 12V/24V systems at lower cost; versus SD103CWS-7, it trades 0.37V higher VF for 10× lower IR, full automotive qualification, and 90°C higher TJmax-critical for under-hood deployment.

FAQ
Is SBR1U200P1Q pin-compatible with standard PowerDI123 Schottky diodes?
Yes-SBR1U200P1Q uses the industry-standard PowerDI123 footprint with anode and cathode terminals in identical positions. Its mechanical dimensions, pad layout recommendations, and soldering profile match those of Diodes' SD103AWS-7 and SBRT1U200P1Q, enabling direct PCB replacement without layout changes.
What is the maximum allowable junction temperature during transient overload conditions?
The absolute maximum junction temperature is +175°C, and the device can sustain short-duration surges (e.g., 40A IFSM for 8.3ms) while staying within this limit, provided the PCB thermal design meets Diodes' recommended 2 oz. copper pad layout and ambient temperature remains ≤+105°C during the event.
Does SBR1U200P1Q require derating at elevated ambient temperatures?
Yes-per Figure 6 in DS39230, ambient temperature must be derated linearly from +175°C at 0A to +100°C at 1.0A. At 75°C ambient, the maximum continuous IO drops to ~0.75A; full 1.0A operation is only guaranteed below +50°C ambient with proper PCB copper area.
Can SBR1U200P1Q be used in synchronous rectification topologies?
No-it is a unidirectional, passive rectifier and lacks gate control or bidirectional conduction capability. It functions as a freewheeling or output rectifier only. For synchronous rectification, discrete MOSFETs or dedicated SR controller ICs (e.g., AP63205) must be used instead.
