Product details
Overview
SBR1U200P1-7 from Diodes Incorporated is a 200 V, 1.0 A surface-mount Super Barrier Rectifier (SBR®) in PowerDI123 package, featuring 0.82 V max forward voltage at 1.0 A and 50 µA max reverse leakage at 200 V, optimized for flyback and reverse polarity protection in DC/DC converters and automotive power supplies.
For engineers reviewing the SBR1U200P1-7 datasheet, SBR1U200P1-7 pinout, SBR1U200P1-7 application, or SBR1U200P1-7 equivalent, key selection criteria include high-temperature stability up to +175°C, soft fast switching (25 ns tRR), AEC-Q101 qualification, and low thermal resistance (138 °C/W on polyimide PCB).
Technical Context
This SBR rectifier uses patented Super Barrier technology to achieve lower forward voltage than Schottky diodes while maintaining higher reverse voltage rating and superior avalanche ruggedness. Its 25 ns reverse recovery time enables efficient operation in high-frequency switching topologies such as flyback and active clamp forward converters.
The PowerDI123 package provides enhanced thermal performance over standard SOD-123, with junction-to-ambient RθJA of 138 °C/W on polyimide PCB and 217 °C/W on FR-4 - critical for compact, thermally constrained designs requiring reliable 1 A continuous conduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1U200P1-7 | Same die, but with tighter VF binning (0.75 V max @ 1 A, 25°C) and enhanced surge rating (50 A IFSM) | Preferred for high-reliability telecom power where margin on conduction loss is critical | Select when VF consistency across temperature and batch is prioritized over cost |
| SS120H-TP | 100 V Schottky, 1 A, 0.52 V VF max - lower VF but half the VRRM; no AEC-Q101 qualification | Suitable only for ≤100 V output rails; not recommended for automotive or harsh-environment use | Choose only for cost-sensitive, non-automotive 5–12 V applications with strict VF targets |
Compared with SBRT1U200P1-7, the SBR1U200P1-7 trades minor VF variation for broader commercial availability and lower unit cost; versus SS120H-TP, it delivers full 200 V capability and automotive qualification at the expense of ~0.3 V higher VF.

FAQ
What is the maximum junction temperature and how does it affect layout?
The SBR1U200P1-7 has a maximum junction temperature of +175°C. To sustain 1.0 A continuous current at elevated ambient temperatures, use the recommended PowerDI123 pad layout (X=1.05 mm, Y=1.50 mm, X2=4.10 mm) on 2 oz. copper FR-4 or polyimide PCB. Thermal resistance drops from 217 °C/W to 138 °C/W with optimized layout, directly extending safe operating area.
Is SBR1U200P1-7 pin-compatible with standard SOD-123 diodes?
No - the PowerDI123 package has identical footprint dimensions to SOD-123 but features a thicker mold compound (1.00 mm vs. 0.90 mm), different thermal pad design, and higher current-carrying leadframe. Direct substitution requires verification of solder joint reliability and thermal performance under actual board layout and airflow conditions.
Does this part support reverse polarity protection in 24 V systems?
Yes - with 200 V VRRM, 50 µA IR at 24 V, and 175°C TJ rating, the SBR1U200P1-7 is widely used as an input-blocking diode in 24 V industrial sensors and actuators. Its low VF (0.68 V typical at 1 A, 125°C) limits power dissipation to 0.68 W, avoiding thermal runaway even in sealed enclosures.
How does its reverse recovery compare to standard FR107 diodes?
The SBR1U200P1-7 achieves 25 ns tRR, versus ~500 ns for FR107. This reduces switching loss and EMI in high-frequency converters. Unlike FR107, it exhibits soft recovery with low stored charge (Qrr ≈ 15 nC), minimizing voltage spikes across MOSFETs and reducing snubber component stress in flyback topologies.
