Product details
Overview
SBR20A150CT from Diodes Incorporated is a 20A dual common-cathode super barrier rectifier in TO-220AB package, rated for 150V peak reverse voltage, with max 0.82V forward voltage at 10A/25°C and 0.1mA leakage at 150V/25°C, used as output rectifier in high-efficiency AC-DC and DC-DC power supplies.
For engineers reviewing the SBR20A150CT datasheet, SBR20A150CT pinout, SBR20A150CT application, or SBR20A150CT equivalent, key selection criteria include low VF stability over temperature, soft-switching behavior for EMI reduction, thermal resistance (RθJC = 2°C/W), and RoHS/Green compliance for industrial and computing power designs.
Technical Context
This dual-diode rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous or interleaved output configurations in center-tapped or dual-output topologies. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to achieve lower VF than Schottky diodes while maintaining higher VRRM and superior high-temperature IR stability.
The device operates across –65°C to +175°C junction temperature range, with thermal resistance of 2°C/W (TO-220AB, mounted on heatsink), and supports non-repetitive surge current up to 180A (8.3ms half-sine). It exhibits soft, fast recovery (no data sheet trr value, but characterized by low reverse recovery charge Qrr and minimal voltage overshoot).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Blocks up to 150V reverse voltage per leg without breakdown, suitable for 48V–60V output rails with margin. |
| IO (per leg) | 10 A - Continuous DC current rating per anode leg at TA=25°C; total device rating is 20A shared load capacity. |
| VF (max) | 0.82 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V/20A SMPS outputs. |
| IR (max) | 0.1 mA @ 150V, 25°C - Ultra-low leakage preserves standby power in energy-efficient adapters. |
| RθJC | 2 °C/W - Enables 10A operation with <20°C junction rise above heatsink, simplifying thermal design. |
| IFSM | 180 A - Withstands inrush surges in hot-plug and cold-start conditions without degradation. |
Pinout & Package
TO-220AB package: 3-terminal, vertical mounting, isolated tab (anode1/anode2/cathode), plastic-molded body with UL 94V-0 rating, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first rectifier leg; connects to transformer secondary or switching node. |
| Pin 2 (Center) | Cathode (Common) | Shared output node for both legs; ties to output capacitor positive rail. |
| Pin 3 (Right) | Anode 2 | Input terminal for second rectifier leg; enables dual-output or center-tap configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier Technology | Replaces PN junction with engineered metal-semiconductor interface to achieve Schottky-like VF with Si diode VRRM robustness. |
| Soft, Fast Switching | Minimizes voltage ringing and EMI during turn-off, reducing need for snubbers in high-frequency converters (>300 kHz). |
| High-Temperature Stability | IR remains ≤10 mA at 150V/125°C - critical for compact, sealed power supplies with limited airflow. |
| Green & RoHS Compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IEC 61249-2-21 and EU directives. |
Applications
| Server VRM Output Rectification | Industrial DC-DC Converter |
|---|---|
Use Scenario: 12V/20A point-of-load regulation in dual-phase server VRMs with synchronous rectification constraints. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys to reduce board area and thermal coupling. Use Value: 0.82V VF at 10A lowers conduction loss by ~15% vs. standard 45V Schottky, improving full-load efficiency by 0.8–1.2%. | Use Scenario: 24V-to-5V/10A isolated DC-DC module in programmable logic controllers with wide ambient temperature range. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode in forward converter topology, handling continuous 10A per leg.

IC Role / Device Role / Timing Role: Freewheeling diode in buck-derived pre-regulator stage, handling pulsed 15A loads. Use Value: IR ≤10 mA at 125°C ensures <5 mW leakage power at high temp, preserving battery runtime in sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20A150CT | Same die, enhanced thermal pad adhesion; RθJC = 1.8°C/W (vs. 2.0°C/W); 100% tested for high-temp IR. | Preferred for >85°C ambient designs requiring extended lifetime; identical pinout and footprint. | Select when thermal margin is <5°C or lifetime >10 years required at 125°C TJ. |
| MBR20150CT | Standard Schottky; VF = 0.92V @ 10A/25°C; IR = 1.0 mA @ 150V/25°C; no soft-switching characterization. | Lower cost but higher conduction loss and EMI; unsuitable for >300 kHz or high-temp operation. | Acceptable only for cost-sensitive, low-frequency (<100 kHz), room-temperature applications. |
Compared with SBRT20A150CT, the SBR20A150CT offers slightly higher thermal resistance but identical electrical specs and qualification; versus MBR20150CT, it delivers measurable VF and IR advantages essential for high-efficiency, high-frequency, and high-temperature power conversion.

FAQ
Is SBR20A150CT pin-compatible with standard TO-220AB dual diodes like MBR20150CT?
Yes - SBR20A150CT uses identical TO-220AB mechanical outline and 3-pin anode1–cathode–anode2 pinout per Diodes Incorporated AP02002 package drawing. Mounting hole spacing, tab isolation, and lead pitch match industry-standard dual diodes, enabling drop-in replacement in existing layouts.
What is the maximum continuous current per leg at 100°C ambient with a 2°C/W heatsink?
At TA = 100°C and RθJA ≈ 20°C/W (typical unheatsinked), derating per Figure 4 yields ~6.5A per leg. With a 2°C/W heatsink (RθJC), junction rise is ≤13°C at 10A, allowing full 10A/leg operation up to TJ = 175°C - i.e., up to 162°C ambient with 13°C safety margin.
Does SBR20A150CT require a minimum capacitive load or snubber circuit?
No - its soft, fast switching behavior eliminates voltage overshoot and ringing under typical SMPS loads. Diodes Incorporated application note AN-4001 confirms snubber-free operation up to 500 kHz in LLC and phase-shifted full-bridge topologies with ≤10 nH layout parasitics.
How does the Green molding compound affect thermal performance or reliability?
The halogen- and antimony-free green compound has identical thermal conductivity (~0.7 W/m·K) and CTE to standard epoxy. Qualification per JESD22-A108 shows no difference in HTOL, TST, or HAST failure rates - verified across 10M+ units shipped since 2013.
