Product details
Overview
SBR20A100CTB-13 from Diodes Incorporated is a 100 V, 20 A total (10 A per leg) dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, featuring 0.85 V max forward voltage at 20 A and 0.1 mA max reverse leakage at 100 V/25°C. It serves as a high-efficiency, thermally stable rectifier or freewheel diode in DC/DC converters and AC/DC adapters.
For engineers reviewing the SBR20A100CTB-13 datasheet, SBR20A100CTB-13 pinout, SBR20A100CTB-13 application, or SBR20A100CTB-13 equivalent, key selection criteria include its low VF stability over temperature, rugged avalanche capability versus Schottky diodes, and JEDEC-qualified reliability for industrial power conversion designs.
Technical Context
This dual-diode rectifier uses patented Trench SBR® technology to achieve superior avalanche energy handling compared to standard Schottky diodes while maintaining ultra-low forward voltage. Its structure enables stable reverse leakage up to +125°C (40 mA max), mitigating thermal runaway risk in high-temperature operation.
The device is rated for 100 V peak repetitive reverse voltage and 250 A non-repetitive surge current (8.3 ms half-sine), with thermal resistance of 5 °C/W (junction-to-case, per leg) when mounted on a 2-inch aluminum substrate - enabling high-power density designs without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage per leg; defines safe operating range in DC/DC output stage or AC input bridge configurations. |
| IO (Total) | 20 A - Total average rectified current capacity across both legs; supports high-current single-output or dual-rail supplies. |
| VF (Max) | 0.85 V @ 20 A, 25°C - Enables >92% conduction efficiency at full load; reduces I²R losses and thermal stress vs. standard Schottky alternatives. |
| IR (Max) | 0.1 mA @ 100 V, 25°C - Ultra-low leakage ensures minimal standby power loss and stable biasing in high-impedance control circuits. |
| RθJC | 5 °C/W (per leg) - Low thermal resistance allows direct mounting to heatsink; supports continuous 10 A/leg operation at ≤100°C ambient with passive cooling. |
| IFSM | 250 A @ 8.3 ms - Withstands transient inrush currents during cold-start or short-circuit recovery without degradation. |
| TJ Range | –65°C to +175°C - Extended junction temperature rating enables use in under-hood automotive power modules or industrial motor drives. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, thermally enhanced plastic case with exposed cathode pad; 1.6 g mass; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode leg | Connects to input/high-side node in synchronous rectification or freewheel path; electrically isolated from Pin 2. |
| Pin 2 (Anode B) | Anode of second diode leg | Enables dual independent rectification paths (e.g., dual-output DC/DC); shares common cathode (Pin 3). |
| Pin 3 (Cathode) | Common cathode terminal | Large copper-exposed pad for low-inductance, low-resistance heat sinking and current return; must be soldered to PCB thermal plane. |
Key Features
| Feature | Design Value |
|---|---|
| Trench SBR® technology | Delivers 2× higher avalanche energy than comparable Schottky diodes, preventing catastrophic failure during voltage transients in buck converter switches. |
| Ultra-low VF drift with temperature | VF increases only 0.09 V from 25°C to 125°C at 10 A, ensuring consistent efficiency and thermal margin across operating range. |
| High-temp IR stability | Reverse leakage remains ≤40 mA at 125°C/100 V - avoids thermal runaway in enclosed power supplies above 85°C ambient. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and JEDEC J-STD-020 Level 1 moisture sensitivity; compatible with lead-free reflow profiles and green manufacturing requirements. |
Applications
| DC/DC Converter Output Rectification | AC/DC Adapter Secondary Side |
|---|---|
Use Scenario: High-efficiency 12 V → 3.3 V/5 V buck converter in telecom power module. IC Role / Device Role / Timing Role: Primary output rectifier replacing Schottky diode to reduce conduction loss and junction temperature rise. Use Value: 0.85 V VF at 20 A lowers power dissipation by ~1.2 W vs. 0.95 V alternative, enabling 10°C lower die temperature at full load. | Use Scenario: 19 V adapter for laptop power supply with dual USB-C outputs. IC Role / Device Role / Timing Role: Dual-leg secondary-side rectifier delivering independent 5 V/3 A and 9 V/3 A rails. Use Value: Common-cathode configuration simplifies PCB layout and reduces component count vs. two discrete diodes; shared thermal pad improves thermal coupling. |
| Freewheel Diode in Motor Drive | Blocking Diode in Solar Charge Controller |
Use Scenario: 24 V BLDC motor driver with PWM-controlled H-bridge. IC Role / Device Role / Timing Role: Freewheel path for inductive kickback during MOSFET turn-off; handles 250 A surge peaks. Use Value: 250 A IFSM rating ensures robustness against back-EMF spikes; low VF minimizes voltage reversal during commutation. | Use Scenario: 12 V solar battery charger with panel input up to 22 V open-circuit. IC Role / Device Role / Timing Role: Reverse-polarity protection and panel-to-battery blocking diode. Use Value: 100 V VRRM provides 2× safety margin over panel Voc; 0.1 mA IR at 25°C prevents night-time battery drain. |
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-20CPH05-M3 | 50 V VRRM, 20 A IO, 0.52 V VF @ 10 A - lower voltage rating, lower VF. | Restricted to ≤50 V systems (e.g., 12 V automotive); unsuitable for 100 V DC bus or universal AC input. | Select only if system VRRM < 60 V and lowest possible VF is critical; verify thermal design for higher IR at elevated temperature. |
| ON Semiconductor MUR20100CT | 100 V VRRM, 20 A IO, 1.1 V VF @ 20 A - standard ultrafast recovery, higher VF, no SBR avalanche enhancement. | Higher conduction loss (+0.25 V) increases thermal load; lacks avalanche ruggedness for inductive switching. | Acceptable where cost is primary constraint and surge immunity is not required; requires larger heatsink for same current. |
Compared with VS-20CPH05-M3 and MUR20100CT, the SBR20A100CTB-13 uniquely balances 100 V blocking, ultra-low VF, and industry-leading avalanche capability - making it optimal for high-reliability, high-efficiency 24–48 V industrial power supplies where thermal margin and transient robustness are critical.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR20A100CTB-13 has an operating junction temperature range of –65°C to +175°C. For continuous operation at rated 20 A total current, thermal design must ensure TJ does not exceed +175°C - typically achieved with RθJA ≤ 10 °C/W using a 2-inch aluminum heatsink and adequate PCB copper area per the datasheet's derating curve.
Is this part suitable for automotive applications?
The SBR20A100CTB-13 is not AEC-Q200 qualified. Diodes Incorporated offers automotive-grade variants with Q-suffix (e.g., SBR20A100CTBQ), which undergo PPAP, are manufactured in IATF 16949 facilities, and meet AEC-Q101 stress testing - required for under-hood or safety-critical vehicle systems.
How does the dual common-cathode configuration affect PCB layout?
The TO263AB package places both anodes (Pins 1 and 2) on one side and the shared cathode (Pin 3) as an exposed thermal pad on the opposite side. This allows compact dual-rail layouts with a single large thermal copper pour connected to Pin 3, reducing parasitic inductance and improving heat spreading versus two discrete SMD diodes.
What is the significance of the "-13" suffix in the part number?
The "-13" suffix indicates tape-and-reel packaging: 800 units per reel. This format is optimized for automated SMT assembly lines. The base part SBR20A100CTB is supplied in 50-piece tubes; both share identical electrical and thermal specifications - only packaging differs.
