Product details
Overview
SBR20100CTFP-JT from Diodes Incorporated is a 100V, 20A total (10A per leg) dual common-cathode Super Barrier Rectifier in ITO-220AB (Type E) package, featuring 0.82V max forward voltage at 10A/25°C and 0.1mA max reverse leakage at 100V/25°C. It delivers rugged avalanche capability and stable high-temperature leakage for DC-DC converters and AC-DC adapters.
For engineers reviewing the SBR20100CTFP-JT datasheet, SBR20100CTFP-JT pinout, SBR20100CTFP-JT application, or SBR20100CTFP-JT equivalent, key selection criteria include its 100V VRRM rating, dual-leg thermal resistance (4°C/W junction-to-case), 150A non-repetitive surge current, isolation voltage (2000VAC), and RoHS-compliant green packaging with halogen/antimony-free materials.
Technical Context
This dual common-cathode rectifier integrates two independent SBR® diode dies in a single isolated TO-style package, enabling synchronous or interleaved rectification topologies without external cathode tying. Its patented Super Barrier structure replaces Schottky architecture to suppress thermal runaway while maintaining ultra-low VF.
The ITO220AB (Type E) variant provides 2000VAC isolation between terminals and heatsink, supporting reinforced insulation in offline power supplies. Thermal performance is defined per leg: RθJC = 4°C/W with specified aluminum heatsink (50 × 50 × 23 mm), and derating begins above 25°C case temperature per Fig. 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 12–48V output DC-DC or universal-input AC-DC designs. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; supports 20A total dual-leg output with shared cathode routing. |
| VF (max) | 0.82 V @ 10A, 25°C - Enables >92% conduction efficiency in 12V-output buck converters at full load, reducing heat sink size. |
| IR (max) | 0.1 mA @ 100V, 25°C - Ensures minimal standby loss in adapter PFC stages; rises to 10mA only at 125°C, limiting thermal runaway risk. |
| EAS | 10 mJ - Non-repetitive avalanche energy rating confirms robustness against inductive switching transients in flyback snubbers. |
| IFSM | 150 A - Peak surge current handling allows reliable cold-start into capacitive loads without bond-wire fusing. |
| VAC (isolation) | 2000 V - Terminal-to-heatsink AC withstand voltage enables direct mounting to grounded chassis in Class I AC-DC adapters. |
Pinout & Package
Package: ITO-220AB (Type E), molded plastic case (UL 94V-0), matte tin-plated copper leadframe, 9.75–10.67 mm height, 15.8–17.0 mm length, 9.72–10.27 mm width, 2.41–2.67 mm lead pitch (e), 3.08–3.39 mm tab width (P). Isolated heatsink interface with 2000VAC rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode terminal | Connects to primary-side switch node in synchronous rectification; electrically isolated from heatsink. |
| Pin 2 (Cathode) | Common cathode | Shared output node for both legs; must be routed with low-inductance path to minimize switching noise coupling. |
| Pin 3 (Anode B) | Second anode terminal | Connects to secondary winding center-tap or second switch node in interleaved topology; same isolation as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Replaces Schottky barrier with controlled heterojunction to eliminate thermally unstable reverse recovery and enable 10mJ avalanche energy handling. |
| Ultra-low VF (0.82V max) | Reduces conduction loss by ~35% vs. standard FRD at 10A, directly lowering MOSFET die temperature in synchronous rectifiers. |
| High-temp IR stability | Leakage remains ≤10mA at 125°C/100V - prevents thermal runaway in sealed enclosures or high-ambient industrial adapters. |
| Green RoHS-compliant package | Halogen- and antimony-free molding compound (<900ppm Br, <900ppm Cl, <1000ppm Sb); meets EU Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles. |
Applications
| Server VRM Output Stage | Industrial AC-DC Adapter |
|---|---|
Use Scenario: High-current, low-voltage output rectification in 48V-to-12V/5V server point-of-load converters with tight thermal constraints. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing discrete MOSFETs; common-cathode configuration simplifies gate drive layout. Use Value: 0.82V VF reduces conduction loss by 1.8W per leg vs. Si FRD, enabling 15°C lower MOSFET junction temperature at 10A. |
Use Scenario: Secondary-side rectification in universal-input (90–264VAC), 36W industrial adapter with reinforced isolation requirements. IC Role / Device Role / Timing Role: Isolated dual-anode rectifier mounted directly to grounded metal chassis via heatsink tab. Use Value: 2000VAC isolation rating eliminates need for insulating pads or bushings, reducing BOM count and assembly cost. |
| Telecom DC-DC Module | LED Driver Power Supply |
Use Scenario: Compact 48V input telecom brick supplying 5V/10A to baseband processing boards in outdoor cabinets. IC Role / Device Role / Timing Role: Interleaved rectifier in active-clamp forward topology; leverages dual-leg symmetry for balanced current sharing. Use Value: 150A IFSM withstands repeated hot-swap events during field maintenance without degradation. |
Use Scenario: Constant-current LED driver for street lighting with wide ambient temperature range (-40°C to +85°C). IC Role / Device Role / Timing Role: Freewheel diode in boost PFC stage; handles 100kHz switching with minimal reverse recovery loss. Use Value: Stable 0.1mA IR at 25°C and ≤10mA at 125°C ensures consistent dimming performance across temperature extremes. |
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 |
|---|---|---|---|
| SBRT20100CTFP | Same ITO220AB (Type E) package but rated for 125°C TJ max (vs. 175°C for SBR20100CTFP-JT); VF = 0.85V max at 10A. | Limited to lower ambient environments; unsuitable for sealed industrial enclosures above 85°C ambient. | Select when cost sensitivity outweighs extended temperature margin and 0.03V higher VF is acceptable. |
| MBR20100CT | Standard Schottky rectifier in TO-220AB; VF = 0.85V max but IR = 1.0mA at 100V/25°C and no avalanche rating. | No isolation voltage rating; requires insulating hardware for chassis-mounting; prone to thermal runaway above 100°C. | Only suitable for non-isolated, low-temperature, cost-driven consumer adapters where reliability margins are relaxed. |
Compared with SBRT20100CTFP and MBR20100CT, SBR20100CTFP-JT uniquely combines 175°C operation, 2000VAC isolation, and 10mJ avalanche energy-enabling single-part qualification across telecom, industrial, and server power designs without derating or safety compromises.

FAQ
What is the thermal resistance (RθJC) for SBR20100CTFP-JT?
The junction-to-case thermal resistance is 4°C/W per leg, measured with a 50 × 50 × 23 mm aluminum heatsink under standardized test conditions (Note 6, DS30956 Rev. 16-2). This value applies to the ITO220AB (Type E) package and assumes full heatsink contact area and proper mounting torque.
Does SBR20100CTFP-JT require a heatsink in all applications?
Yes - continuous operation at rated 10A per leg requires a heatsink to maintain junction temperature below 175°C. At 25°C ambient and 10A load, the device dissipates ~8.2W (0.82V × 10A); without heatsinking, case temperature would exceed safe limits within seconds.
How does the isolation voltage rating affect PCB layout?
The 2000VAC terminal-to-heatsink isolation allows direct mounting to a grounded metal chassis without insulating hardware. PCB layout must maintain ≥4.5mm creepage/clearance between exposed anode pads and any grounded copper pour, per IEC 62368-1 reinforced insulation requirements.
Is SBR20100CTFP-JT compatible with lead-free reflow profiles?
Yes - it is qualified for JEDEC J-STD-020D Level 3 moisture sensitivity and supports peak reflow temperatures up to 260°C. The matte tin finish on copper leadframe ensures solderability per MIL-STD-202, Method 208, and complies with RoHS 2 (2011/65/EU) and Diodes' green material specifications.
