Product details
Overview
SBR30A100CTFP-JT from Diodes Incorporated is a 100 V, 30 A dual common-cathode Super Barrier Rectifier in ITO-220AB (Type E) package, featuring 0.80 V max forward voltage at 15 A per leg and 0.1 mA max reverse leakage at 100 V/25°C. It delivers rugged avalanche capability (550 mJ), low thermal resistance (4 °C/W), and stable high-temperature operation-ideal for primary-side rectification in AC-DC adapters and secondary-side freewheeling in DC-DC converters.
For engineers reviewing the SBR30A100CTFP-JT datasheet, SBR30A100CTFP-JT pinout, SBR30A100CTFP-JT application, or SBR30A100CTFP-JT equivalent, key selection criteria include per-leg current rating (15 A), total device current (30 A), isolation voltage (2,000 VAC), thermal resistance (4 °C/W), and RoHS-compliant green packaging with matte tin terminals.
Technical Context
This dual-diode rectifier integrates two independent SBR (Super Barrier Rectifier) junctions sharing a common cathode terminal. Its patented barrier structure enables lower VF than Schottky diodes while maintaining superior avalanche ruggedness-critical for unregulated or transient-prone power rails.
Rated for 100 V repetitive reverse voltage and 250 A non-repetitive surge current, it operates across –65°C to +175°C with minimal reverse leakage drift up to 125°C. The ITO-220AB (Type E) package provides electrical isolation between terminals and heatsink, enabling direct mounting without insulating hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in rectifier or freewheeling configurations. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg; determines thermal design margin when used in dual-leg topology. |
| VF (max) | 0.80 V @ 15 A, 25°C - Low conduction loss improves system efficiency and reduces heat sink requirements in high-current DC-DC stages. |
| IR (max) | 0.1 mA @ 100 V, 25°C - Ultra-low leakage ensures stable performance in high-impedance bias networks and prevents thermal runaway at elevated temperatures. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB; enables accurate heatsink sizing when mounted on aluminum (50 × 50 × 23 mm). |
| IAS / EAS | 10 A / 550 mJ - Non-repetitive avalanche energy rating confirms robustness against inductive switching transients in flyback or buck converter freewheel paths. |
| VAC (isolation) | 2,000 VAC - Terminal-to-heatsink isolation voltage allows safe mounting to grounded chassis in isolated AC-DC power supplies. |
Pinout & Package
Package: ITO-220AB (Type E), thermally enhanced plastic case with electrically isolated tab (heatsink interface), UL 94V-0 rated molding compound, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode connection | Independent input path for first diode leg; used in dual-output or interleaved rectifier topologies. |
| Pin 2 (Cathode) | Common cathode node | Shared output node for both diode legs; simplifies PCB layout and reduces parasitic inductance in high-frequency switching applications. |
| Pin 3 (Anode B) | Second anode connection | Independent input path for second diode leg; supports symmetrical current sharing in center-tapped transformer designs. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR technology | Enables 0.80 V VF at 15 A while sustaining 550 mJ avalanche energy-superior ruggedness vs. standard Schottky diodes in surge-prone environments. |
| Ultra-low high-temp IR | 0.1 mA max at 25°C and <10 mA at 125°C-minimizes standby power loss and avoids thermal runaway in enclosed, high-ambient applications. |
| Electrically isolated tab | 2,000 VAC isolation between terminals and heatsink-eliminates need for insulating washers or pads in grounded-chassis AC-DC adapters. |
| Green RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb), lead-free matte tin finish-meets global environmental compliance mandates without derating. |
Applications
| AC-DC Adapters | DC-DC Converters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 30–65 W wall adapters with universal AC input (90–264 VAC). IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing discrete Schottkys to reduce conduction loss and improve no-load efficiency. Use Value: 0.80 V VF lowers output stage losses by ~15% vs. comparable Schottky, directly improving full-load efficiency and reducing heatsink size. |
Use Scenario: Freewheeling diode in 12 V → 3.3 V/5 V buck converters for industrial PLC I/O modules. IC Role / Device Role / Timing Role: High-current flyback path during MOSFET off-time; handles 15 A peak currents with minimal voltage overshoot. Use Value: 550 mJ avalanche rating absorbs inductive energy from 8.5 mH chokes without failure, increasing reliability in harsh EMC environments. |
| Telecom Power Supplies | LED Driver Circuits |
Use Scenario: Output rectification in -48 V telecom rectifiers operating continuously at 60°C ambient. IC Role / Device Role / Timing Role: Primary output diode handling 30 A total continuous current in redundant parallel configuration. Use Value: Stable 0.1 mA IR at 25°C and <10 mA at 125°C prevents thermal runaway under sustained overload, extending field lifetime. |
Use Scenario: Constant-current LED string rectification in outdoor street lighting drivers (IP67-rated enclosures). IC Role / Device Role / Timing Role: Bridge rectifier input stage feeding boost PFC stage; withstands 2,000 VAC isolation during lightning surge testing. Use Value: Electrically isolated tab eliminates creepage/clearance concerns on PCB, simplifying UL/EN61347 certification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT30A100CTFP | Same ITO-220AB (Type E) package, identical 100 V/30 A rating, but uses enhanced SBR+ process yielding 0.75 V VF (typ) at 15 A and 0.05 mA IR (max) at 100 V/25°C. | Better suited for ultra-high-efficiency 80 PLUS Titanium designs where sub-0.75 V VF and <0.1 mA leakage are mandatory. | Select when optimizing for lowest possible conduction loss and highest temperature stability; requires validation of enhanced avalanche behavior under same test conditions. |
| MBR30100CT | Standard Schottky dual-diode in TO-220AB; 100 V/30 A rating but higher VF (0.95 V max) and no isolation voltage rating; RθJC = 2 °C/W. | Acceptable in non-isolated, cost-sensitive consumer adapters where heatsink space is abundant and 2,000 VAC isolation is unnecessary. | Choose only if isolation and high-temp leakage are not critical; avoid in telecom or industrial applications requiring long-term thermal reliability. |
Compared with SBRT30A100CTFP, SBR30A100CTFP-JT offers proven field reliability with slightly higher VF and leakage, while MBR30100CT trades isolation and thermal stability for lower cost and wider availability-but lacks ruggedness for surge-heavy environments.

FAQ
What is the maximum junction temperature for SBR30A100CTFP-JT?
The absolute maximum junction temperature is +175°C, with continuous operation rated from –65°C to +175°C. Derating begins above +25°C ambient per Figure 4 in DS30983 Rev. 10–2; at 100°C ambient, maximum average forward current drops to ~9.5 A per leg with a 50 × 50 × 23 mm heatsink.
Is SBR30A100CTFP-JT pin-compatible with SBR30A100CT?
No-SBR30A100CT uses TO-220AB (non-isolated tab), while SBR30A100CTFP-JT uses ITO-220AB (Type E) with electrically isolated tab. Pin numbering is identical (Anode–Cathode–Anode), but mechanical mounting and thermal interface differ significantly; substitution requires PCB and heatsink redesign.
Does SBR30A100CTFP-JT require a thermal pad or insulator when mounted to a heatsink?
No-its ITO-220AB (Type E) package provides 2,000 VAC isolation between terminals and heatsink, allowing direct metal-to-metal mounting without insulating hardware. This eliminates thermal interface resistance from mica or silicone pads, improving thermal transfer efficiency.
How does the SBR technology differ from standard Schottky diodes in practice?
SBR uses a modified barrier structure that reduces forward voltage while retaining silicon PN-junction-like avalanche capability. Unlike Schottkys-which fail catastrophically under moderate surge-the SBR30A100CTFP-JT safely absorbs 550 mJ of inductive energy, making it suitable for flyback snubbers and unregulated DC-DC outputs where voltage spikes are common.
