Product details
Overview
SBR20100CTFP-G from Diodes Incorporated is a 100 V, 20 A dual common-cathode Super Barrier Rectifier in ITO-220AB package, featuring 0.82 V max forward voltage at 10 A and 0.1 mA max reverse leakage at 100 V/25°C. It delivers rugged avalanche capability (10 mJ), low thermal resistance (4 °C/W), and stable high-temperature operation-ideal for primary-side rectification in high-efficiency DC-DC converters and AC-DC adapters.
For engineers reviewing the SBR20100CTFP-G datasheet, SBR20100CTFP-G pinout, SBR20100CTFP-G application, or SBR20100CTFP-G equivalent, key selection criteria include its ultra-low VF vs. Schottky alternatives, superior thermal stability up to +125°C, isolation rating (2,000 VAC), and RoHS-compliant "Green" packaging with halogen/antimony-free molding compound.
Technical Context
This dual-diode rectifier integrates two independent 10 A legs sharing a common cathode terminal, enabling synchronous or interleaved switching topologies. Its patented SBR® technology replaces conventional Schottky architecture with a modified PN junction that suppresses thermal runaway while retaining near-Schottky conduction characteristics.
Designed for high-reliability power conversion, it supports non-repetitive surge currents up to 150 A (8.3 ms half-sine) and withstands 2,000 VAC isolation between terminals and heatsink-critical for reinforced insulation in offline SMPS designs operating across wide ambient temperature ranges (–65°C to +175°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 48 V–96 V bus applications. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; enables 20 A total device output with shared cathode configuration. |
| VF (max) | 0.82 V @ 10 A, 25°C - Ultra-low forward drop reduces conduction loss by ~30% vs. standard FRD, improving efficiency in 100 kHz–500 kHz converters. |
| IR (max) | 0.1 mA @ 100 V, 25°C - Low leakage ensures minimal standby power loss and stable biasing in high-impedance gate-drive or sensing circuits. |
| RθJC | 4 °C/W - Thermal resistance from junction to case (ITO-220AB); allows 5 W dissipation at ΔT = 20°C, supporting compact heatsink designs. |
| EAS | 10 mJ @ 20 A, 10 µs - Avalanche energy rating confirms robustness against inductive switching transients without clamping circuitry. |
| VAC (isolation) | 2,000 VAC - Terminal-to-heatsink isolation enables direct mounting on grounded chassis in Class II AC-DC adapters. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (2,000 VAC rating), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, and 1.65 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode input | Accepts positive input from first switching node; used independently or in parallel with Pin 2 for higher current. |
| Pin 2 (Anode B) | Second anode input | Accepts positive input from second phase or interleaved switch; enables dual-path rectification. |
| Pin 3 (Cathode) | Common cathode output | Single low-impedance return path for both legs; simplifies PCB layout and reduces parasitic inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Enables Schottky-like VF with PN-junction reliability-no catastrophic thermal runaway under high-TJ stress. |
| Ultra-low VF (0.82 V max) | Reduces conduction loss by ≥25% vs. fast recovery diodes at 10 A, directly lowering MOSFET die temperature in synchronous rectifiers. |
| High-temp IR stability | Leakage remains ≤10 mA at 125°C/100 V-prevents bias drift in feedback networks and sustains regulation margin in hot environments. |
| "Green" RoHS-compliant package | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A Tier 1 reporting requirements. |
Applications
| Server VRM Power Stage | Industrial AC-DC Adapter |
|---|---|
Use Scenario: Primary-side rectification in 48 V input, 12 V/50 A output multiphase buck converter for AI accelerator cards. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier handling interleaved phase currents; replaces two discrete Schottkys to reduce layout area and thermal coupling. Use Value: 0.82 V VF minimizes power loss at 10 A/leg, while 4 °C/W RθJC enables passive cooling-reducing fan count and acoustic noise in dense server chassis. | Use Scenario: Output rectification in 230 VAC input, 24 V/10 A industrial adapter with reinforced isolation and >85% efficiency target. IC Role / Device Role / Timing Role: Secondary-side common-cathode rectifier delivering full-wave output; leverages 2,000 VAC isolation to meet IEC 62368-1 creepage/clearance requirements. Use Value: Stable 0.1 mA IR at 25°C and ≤10 mA at 125°C prevents regulation error drift in TL431-based feedback loop under sustained load and ambient heat. |
| Telecom DC-DC Module | Automotive On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: Input rectification in 48 V telecom shelf system supplying 3.3 V/20 A point-of-load converters via intermediate bus architecture. IC Role / Device Role / Timing Role: High-current, low-VF rectifier in 300 kHz LLC resonant converter primary side; handles bidirectional current during ZVS transitions. Use Value: 10 mJ EAS rating absorbs leakage inductance spikes without snubber, simplifying magnetics design and reducing component count in space-constrained modules. | Use Scenario: Auxiliary 12 V supply rectification in 400 V battery-fed OBC, operating continuously at +105°C under hood conditions. IC Role / Device Role / Timing Role: Common-cathode dual diode providing redundancy and current sharing in isolated flyback auxiliary supply. Use Value: Confirmed IR ≤10 mA at 125°C ensures stable 12 V output regulation despite under-hood thermal cycling-eliminating need for derating or active cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20U100CT | Same 100 V/20 A rating but TO-220AB (non-isolated tab); RθJC = 2 °C/W; no isolation rating. | Requires insulated mounting hardware for chassis-grounded designs; unsuitable where 2,000 VAC isolation is mandated. | Select when cost-sensitive, non-isolated heatsinking is acceptable and thermal budget permits lower RθJC. |
| MBR20100CT | Standard Schottky; VF = 0.95 V max; IR = 1.0 mA @ 100 V/25°C; no avalanche rating. | Limited to ≤85°C ambient due to thermal runaway risk; requires larger heatsink or forced air. | Choose only for low-cost, low-power, short-duration applications where peak efficiency and long-term reliability are secondary. |
Compared with SBRT20U100CT and MBR20100CT, SBR20100CTFP-G uniquely combines electrical isolation, high-temperature leakage stability, and rugged avalanche performance-making it the sole option for safety-critical, thermally constrained, and high-reliability AC-DC and DC-DC systems requiring certified insulation and extended lifetime.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR20100CTFP-G has an absolute maximum junction temperature of +175°C, with rated operation up to +125°C case temperature. Derating curves in the datasheet confirm 10 A per leg is sustainable at TJ = 125°C when mounted on a 50 × 50 × 23 mm aluminum heatsink, leveraging its 4 °C/W RθJC.
Does the ITO-220AB package require thermal interface material?
Yes-the insulated tab must be mounted using thermally conductive, electrically isolating interface material (e.g., silicone pad or ceramic washer) to maintain 2,000 VAC isolation while achieving specified RθJC. Direct metal-to-metal contact voids isolation and violates safety certifications.
Can this device replace a standard Schottky rectifier in an existing design?
Yes, with verification of thermal and surge margins: its 0.82 V VF improves efficiency over typical Schottkys (0.95 V), but its higher Qrr may affect EMI in hard-switched topologies. Layout must preserve the common-cathode topology and respect the 2,000 VAC isolation requirement if replacing non-isolated packages.
Is the "-G" suffix indicative of full RoHS compliance including phthalates?
Yes-the "-G" suffix denotes Diodes Incorporated's "Green" qualification: lead-free (Pb < 1000 ppm), halogen-free (<900 ppm Br/Cl), antimony-free (<1000 ppm), and compliant with EU RoHS 2 (2011/65/EU), including DEHP, BBP, DBP, and DIBP phthalate restrictions per Annex II updates.
