Product details
Overview
SBR30300CTFP-JT from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier rated for 300V peak reverse voltage, with VF ≤ 0.92 V at 15A/125°C and trr ≤ 35 ns under specified switching conditions; used in high-efficiency AC-DC front-end rectification and DC-DC secondary-side synchronous replacement in telecom power supplies.
For engineers reviewing the SBR30300CTFP-JT datasheet, SBR30300CTFP-JT pinout, SBR30300CTFP-JT application, or SBR30300CTFP-JT equivalent, key selection criteria include forward voltage drop at elevated temperature, soft-recovery behavior for EMI control, thermal resistance (RθJC = 4°C/W), and ITO-220AB isolation rating (2000 VAC).
Technical Context
This device integrates two independent 300V/15A rectifying elements in a single ITO-220AB package with common cathode configuration, enabling dual-output or interleaved converter topologies. Its patented Super Barrier structure replaces traditional PN junctions with low-barrier metal-semiconductor interfaces, delivering lower VF than Schottky diodes while maintaining higher temperature stability and leakage immunity.
The soft, fast recovery (trr ≤ 35 ns) minimizes switching losses and voltage overshoot during turn-off, especially critical in high-frequency LLC and phase-shifted full-bridge converters. Isolation voltage of 2000 VAC between terminals and heatsink supports direct mounting to grounded chassis in Class I AC-DC systems without additional insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking capability per leg; defines usable input voltage range in offline rectifiers. |
| IO (per leg) | 15 A - Continuous average forward current per element at TC = 100°C; enables 30A total dual-leg output with shared thermal path. |
| VF @ 15A/125°C | ≤ 0.92 V - Low conduction loss at operating temperature; reduces heat generation vs. standard Schottky or fast recovery diodes. |
| trr | ≤ 35 ns - Soft, fast reverse recovery; limits di/dt-induced ringing and EMI in high-frequency SMPS designs. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB; allows accurate heatsink sizing when mounted with thermal interface material. |
| VAC (isolation) | 2000 V - Withstand voltage from leads to heatsink; eliminates need for insulating pads in grounded-chassis applications. |
| IR @ 300V/125°C | ≤ 10 mA - Low high-temp leakage ensures stable operation in hot environments without thermal runaway risk. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (2000 VAC rating), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, weight ≈ 1.65 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first rectifier element | Connects to AC input or transformer secondary winding; carries half of total forward current. |
| Pin 2 (Cathode) | Common cathode node | Shared output node for both rectifier legs; connects to bulk capacitor or DC bus; requires low-inductance layout. |
| Pin 3 (Anode B) | Anode of second rectifier element | Enables dual-output or interleaved operation; independent from Pin 1 but thermally coupled via common case. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier technology | Combines low VF of Schottky with high-temperature stability and low IR of PN diodes-no compromise on leakage at 125°C. |
| Soft-switching recovery | Controlled minority-carrier recombination reduces dV/dt-induced EMI and snubber losses in >100 kHz converters. |
| ITO-220AB isolation | 2000 VAC isolation enables direct heatsink mounting to earth ground-reduces BOM count and assembly cost. |
| RoHS-compliant & green compound option | Lead-free matte tin finish and halogen-free molding compound meet IPC-1752 and EU environmental mandates. |
Applications
| Telecom AC-DC Power Supply | Server VRM Secondary Rectification |
|---|---|
Use Scenario: High-density 48 V input rectification stage in -48 V telecom systems with strict efficiency targets. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys; handles 30 A total output with shared thermal path. Use Value: 0.92 V VF at 125°C cuts conduction loss by ~18% vs. comparable 300 V Schottky, directly improving system efficiency at full load. | Use Scenario: Secondary-side synchronous rectification in multiphase buck converters feeding CPU/GPU rails. IC Role / Device Role / Timing Role: Fast, soft-recovery rectifier paired with gate drivers; operates at 300–500 kHz with minimal reverse recovery charge. Use Value: trr ≤ 35 ns and low Qrr reduce switching node oscillation, easing EMI filter design and improving transient response. |
| Industrial Motor Drive DC Link | LED Streetlight Power Module |
Use Scenario: Input bridge rectification in 3-phase PFC + DC link stages for variable frequency drives. IC Role / Device Role / Timing Role: High-current, high-temperature rectifier handling 15 A per leg under continuous 105°C ambient conditions. Use Value: RθJC = 4°C/W and 175°C max TJ allow reliable operation without oversized heatsinks in enclosed cabinets. | Use Scenario: Constant-current LED driver with universal AC input and passive cooling requirements. IC Role / Device Role / Timing Role: Bridge rectifier in flyback or buck-boost topology where leakage and thermal derating impact lumen maintenance. Use Value: IR ≤ 10 mA at 125°C prevents thermal runaway in sealed outdoor enclosures, extending driver lifetime beyond 50,000 hours. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage Super Barrier Rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH03-M3 | 300 V, 15 A per leg; VF = 0.88 V @ 15A/25°C but degrades to 1.05 V @ 125°C; trr = 45 ns. | Higher VF at elevated temperature increases conduction loss in thermally constrained designs. | Select if lower room-temp VF is prioritized and thermal margin exists. |
| ON Semiconductor MUR3030CT | 300 V, 15 A per leg; fast recovery (trr = 60 ns), VF = 1.25 V @ 15A/125°C; no isolation rating. | Lacks 2000 VAC isolation and has higher VF-requires insulated mounting hardware and dissipates more heat. | Select only when isolation is not required and cost is primary constraint. |
Compared with VS-30CPH03-M3 and MUR3030CT, SBR30300CTFP-JT delivers superior thermal stability (0.92 V vs. ≥1.05 V at 125°C), lower EMI due to softer recovery (35 ns vs. ≥45 ns), and integrated isolation-reducing bill-of-materials and layout complexity in safety-critical AC-DC systems.

FAQ
What is the difference between SBR30300CTFP-JT and SBR30300CTFP?
SBR30300CTFP-JT is an alternate packaging variant of SBR30300CTFP, both using the ITO-220AB package with identical electrical specifications and thermal performance. The "-JT" suffix denotes a specific tape-and-reel or tube packaging configuration per Diodes' internal ordering matrix-not a functional or parametric revision.
Can SBR30300CTFP-JT be used as a direct replacement for standard TO-220AB rectifiers?
No-it uses the ITO-220AB package with electrically isolated tab (2000 VAC rating), whereas standard TO-220AB has conductive tab. Mechanical fit is identical, but electrical isolation must be verified in the target PCB layout; no insulating pad is needed when mounting to grounded heatsinks.
What is the maximum recommended case temperature for continuous operation?
The absolute maximum case temperature is 175°C, but continuous operation above 100°C requires derating per Figure 1 in DS30995. At TC = 100°C, IO per leg is 15 A; at TC = 125°C, it drops to approximately 11.5 A. Thermal design must ensure TC stays within this envelope under worst-case airflow and ambient conditions.
Does SBR30300CTFP-JT support RoHS and REACH compliance?
Yes-SBR30300CTFP-JT features lead-free matte tin plating and complies with EU Directive 2002/95/EC (RoHS), including all applicable exemptions. It also meets REACH SVHC requirements and is manufactured with green (halogen-free) molding compound unless otherwise specified by the "-G" suffix.
