Product details
Overview
SBR20A120CT-G-E1 from Diodes Incorporated is a 120 V, 20 A total (10 A per leg) Super Barrier Rectifier in TO-220AB package, featuring 0.79 V max forward voltage at 10 A and 0.1 mA max reverse leakage at 125°C. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters where thermal stability and low conduction loss are critical.
For engineers reviewing the SBR20A120CT-G-E1 datasheet, SBR20A120CT-G-E1 pinout, SBR20A120CT-G-E1 application, or SBR20A120CT-G-E1 equivalent, key selection criteria include peak repetitive reverse voltage (120 V), average output current per leg (10 A), forward voltage drop at rated current, high-temperature reverse leakage performance, and TO-220AB thermal resistance (2°C/W junction-to-case).
Technical Context
This dual-die Super Barrier Rectifier integrates two independent 10 A rectifying elements in a single TO-220AB package with common cathode configuration. Its patented SBR technology delivers superior avalanche ruggedness compared to Schottky diodes while maintaining ultra-low VF and stable IR across temperature.
The device operates over –65°C to +175°C junction temperature range and is rated for 180 A non-repetitive surge current. Thermal resistance of 2°C/W (TO-220AB, with heatsink) enables reliable operation in high-power density power supplies without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - Withstands up to 120 V repetitive reverse voltage without breakdown, suitable for 48 V and 60 V bus systems. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg, enabling 20 A total dual-leg rectification. |
| VF (max) | 0.79 V @ 10 A, 25°C - Low conduction loss improves efficiency and reduces heat generation in high-current paths. |
| IR (max) | 0.1 mA @ 120 V, 125°C - Exceptionally low high-temp leakage prevents thermal runaway in enclosed or high-ambient environments. |
| RθJC | 2°C/W - Junction-to-case thermal resistance allows direct mounting to heatsinks for effective thermal management. |
| IFSM | 180 A @ 8.3 ms - Robust surge capability handles inrush and transient overloads in switching power supplies. |
Pinout & Package
Package: TO-220AB - Molded plastic case with matte tin-plated copper leadframe, UL 94V-0 rated, 1.85 g weight, designed for vertical mounting and heatsink attachment via tab (cathode-connected metal back).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first rectifier die | Independent input terminal for first 10 A leg; electrically isolated from Pin 2. |
| Pin 2 (Anode 2) | Anode of second rectifier die | Independent input terminal for second 10 A leg; shares cathode (Pin 3) with Pin 1. |
| Pin 3 (Cathode) | Common cathode connection | Single output node for both legs; electrically connected to metal tab for heatsinking and low-inductance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR technology | Enables higher avalanche energy rating than Schottky diodes, improving system robustness against voltage transients. |
| Ultra-low VF at high current | 0.79 V max at 10 A/25°C ensures >1% efficiency gain vs. standard fast recovery diodes in 12–24 V output converters. |
| Stable high-temp IR | 0.1 mA max at 125°C supports reliable operation in sealed enclosures or automotive under-hood applications. |
| Lead-free & Halogen-free | RoHS-compliant and "Green" certified (<900 ppm Br/Cl, <1000 ppm Sb), meeting IPC-1752 and EU environmental directives. |
Applications
| DC-DC Converter Output Rectification | AC-DC Adapter Secondary Side |
|---|---|
Use Scenario: High-frequency synchronous buck converter delivering 12 V/15 A from 48 V input in telecom power shelf. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete diodes to reduce PCB area and thermal interface count. Use Value: 0.79 V VF minimizes conduction loss; 2°C/W RθJC enables passive heatsinking, reducing fan dependency and acoustic noise. | Use Scenario: 36 W universal-input offline adapter powering IoT gateway with 5 V/3 A and 12 V/1 A outputs. IC Role / Device Role / Timing Role: Secondary-side output rectifier for main 5 V winding, operating at 100 kHz flyback frequency.

IC Role / Device Role / Timing Role: Freewheel path for inductive kickback during PWM off-time, clamping voltage spikes across MOSFETs. Use Value: 180 A IFSM withstands repeated commutation surges; SBR ruggedness avoids avalanche-induced failure during short-circuit events. | Use Scenario: 24 V battery charging circuit with PV input up to 40 V, requiring reverse polarity protection and MPPT tracking. IC Role / Device Role / Timing Role: Blocking diode between solar panel array and charge controller to prevent battery discharge at night. Use Value: 120 V VRRM provides 2× margin over 40 V PV open-circuit voltage; low VF preserves >98% of harvested energy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20A120CT | Same electrical specs but optimized for tighter VF distribution (0.75 V typ); slightly higher cost. | Preferred in high-volume consumer adapters where binning consistency improves yield. | Select when production test limits require tighter VF matching across units. |
| MBR20120CT | Standard Schottky; 0.92 V VF max @ 10 A, 10× higher IR at 125°C (1 mA vs. 0.1 mA). | Acceptable in lower-ambient, lower-reliability applications where cost is primary. | Choose only if thermal derating and long-term leakage stability are not design constraints. |
Compared with SBRT20A120CT and MBR20120CT, SBR20A120CT-G-E1 delivers optimal balance of low VF, ultra-stable high-temp leakage, and rugged avalanche performance-making it preferred for industrial and telecom power where reliability and efficiency co-prioritize.

FAQ
What is the pin configuration of SBR20A120CT-G-E1?
It uses a TO-220AB 3-pin configuration: Pin 1 = Anode 1, Pin 2 = Anode 2, Pin 3 = Common Cathode (connected to metal tab). The cathode tab must be electrically isolated from heatsink unless referenced to system ground, and serves as the primary thermal path.
Is SBR20A120CT-G-E1 RoHS and halogen-free compliant?
Yes-SBR20A120CT-G-E1 carries the "-G" suffix indicating Diodes Incorporated's Green standard: fully RoHS 2 compliant (2011/65/EU), with <900 ppm bromine/chlorine and <1000 ppm antimony, verified per IPC-1752 and company internal testing protocols.
How does its thermal performance compare to standard Schottky rectifiers?
SBR20A120CT-G-E1 offers 2°C/W RθJC (TO-220AB) and maintains 0.1 mA IR at 125°C-significantly better than typical Schottkys (e.g., MBR20120CT: ~1 mA IR at same condition). This enables higher ambient operation without thermal runaway in sealed enclosures.
Can it replace a single 20 A Schottky diode in a common-cathode layout?
No-it is a dual 10 A per leg device with separate anodes and shared cathode. It replaces two discrete 10 A diodes-not one 20 A diode. Using it as a single-anode device would underutilize one die and violate current derating rules per leg.
