Product details
Overview
SBR30A120CT-G-E1 from Diodes Incorporated is a 30A dual common-cathode super barrier rectifier rated for 120V reverse voltage, featuring 0.78V typical forward voltage at 15A/25°C and 175°C maximum junction temperature, optimized for high-efficiency AC-DC front-end and DC-DC secondary-side rectification in industrial power supplies.
For engineers reviewing the SBR30A120CT-G-E1 datasheet, SBR30A120CT-G-E1 pinout, SBR30A120CT-G-E1 application, or SBR30A120CT-G-E1 equivalent, key selection criteria include forward voltage consistency across temperature, soft-switching behavior to reduce EMI, thermal resistance (2°C/W junction-to-case), and RoHS-compliant green molding compound compatibility with lead-free reflow profiles.
Technical Context
This device integrates two independent 15A rectifying legs sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented super barrier structure replaces traditional PN junctions with low-resistance metal-semiconductor interfaces, delivering lower VF than Schottky diodes while maintaining higher reverse blocking capability than standard silicon diodes.
The TO-220AB package provides direct heatsink mounting via the metal tab (pin 2), with thermal resistance of 2°C/W (junction-to-case) and isolation rating not applicable - unlike ITO-220AB variants, this variant lacks internal insulation between tab and cathode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - Maximum repetitive reverse voltage before breakdown; sets usable input range in 100–120VAC-derived supplies. |
| IO (per leg) | 15 A - Continuous average forward current per anode leg; supports 30A total output when both legs used in parallel configuration. |
| VF @ 15A/25°C | 0.78 V - Low conduction loss enabling >94% efficiency in 12V-output secondary-side rectification. |
| IFSM | 250 A - Non-repetitive surge rating; withstands inrush currents during cold-start of switched-mode power supplies. |
| TJ max | +175°C - Enables operation in high-ambient environments (e.g., enclosed industrial enclosures) without derating below 15A. |
| RθJC | 2°C/W - Confirms effective thermal path from die to case; requires ≥15 cm² heatsink area for sustained 30A operation at 70°C ambient. |
| IR @ 120V/125°C | 20 μA - Ultra-low leakage preserves hold-up time in standby mode and reduces no-load power consumption. |
Pinout & Package
Package: TO-220AB - Insulated plastic case with copper leadframe, matte tin-plated terminals, UL 94V-0 flammability rating, and metal tab (pin 2) electrically connected to cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Left) | Anode Leg A | Input terminal for first rectifying path; connects to transformer secondary or switching node. |
| 2 (Center / Tab) | Common Cathode | Electrically tied to cathode of both legs; serves as main heat dissipation surface and output return path. |
| 3 (Right) | Anode Leg B | Input terminal for second rectifying path; enables center-tapped transformer or dual-phase rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier Technology | Replaces PN junction with low-VF metal-semiconductor interface, achieving Schottky-like conduction without thermal runaway risk. |
| Soft Switching | Controlled reverse recovery minimizes voltage spikes and EMI generation during turn-off, reducing need for snubbers in high-frequency SMPS. |
| 175°C Junction Rating | Enables full-rated current delivery in ambient temperatures up to 100°C with appropriate heatsinking, supporting fanless industrial designs. |
| Green Molding Compound | Halogen- and antimony-free formulation (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A Class 3 material declarations for eco-compliance. |
| Lead-Free & RoHS Compliant | Matte tin finish on copper leadframe ensures solderability per MIL-STD-202 Method 208 and compatibility with Pb-free reflow profiles (peak 260°C). |
Applications
| Server Power Supply | Industrial Motor Drive |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48V-output LLC resonant converters for rack-mounted servers. IC Role / Device Role / Timing Role: Dual-leg common-cathode configuration replaces two discrete Schottkys, simplifying PCB layout and improving thermal coupling to heatsink. Use Value: 0.78V VF at 15A reduces conduction loss by 1.2W per leg versus 0.85V alternatives, lowering thermal stress in dense 1U form factors. | Use Scenario: DC bus freewheeling and regeneration path in 3-phase IGBT inverter stages for HVAC compressors. IC Role / Device Role / Timing Role: Handles bidirectional energy flow during motor deceleration; soft recovery prevents voltage overshoot on IGBT collector. Use Value: 250A IFSM rating supports peak regenerative currents exceeding 200A without degradation, extending inverter reliability. |
| Telecom Rectifier | Renewable Energy Inverter |
Use Scenario: Input rectification stage in -48V telecom power systems with wide input range (36–72VDC). IC Role / Device Role / Timing Role: Operates in continuous conduction mode with minimal forward drop variation over load and temperature. Use Value: 0.65V VF at 15A/125°C maintains stable output regulation under high-temperature base station conditions. | Use Scenario: MPPT boost-stage output rectification in solar microinverters handling 25A DC input from PV panels. IC Role / Device Role / Timing Role: Dual-anode topology allows interleaved operation with external gate control, reducing ripple current stress on output capacitors. Use Value: 2°C/W RθJC enables direct-mount heatsinking to aluminum chassis, eliminating need for thermal interface pads in compact outdoor enclosures. |
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 |
|---|---|---|---|
| Vishay VS-30CPH12 | Same 120V VRRM, but 0.82V VF @ 15A/25°C; TO-247AC package with higher RθJC (1.5°C/W) but no insulated tab. | Requires separate insulating hardware for heatsink mounting; better suited for space-constrained layouts where footprint is critical. | Select when board real estate is limited and thermal interface materials are acceptable. |
| ON Semiconductor MUR30120CT | Ultrafast recovery rectifier (trr = 60ns), higher VF (0.95V @ 15A), 150°C TJ max; TO-220AB package. | Higher switching loss and lower temperature margin; suitable only where cost is prioritized over efficiency and thermal headroom. | Choose only for legacy designs requiring pin-for-pin replacement with no thermal redesign. |
Compared with VS-30CPH12 and MUR30120CT, SBR30A120CT-G-E1 delivers superior thermal performance (175°C rating + 2°C/W RθJC), lower conduction loss (0.78V vs. 0.82V/0.95V), and integrated green compliance - making it optimal for new high-efficiency, thermally constrained industrial power designs.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.
This device belongs to Diodes' SBR® (Super Barrier Rectifier) product line, engineered specifically to replace Schottky diodes in high-current, high-temperature power conversion applications where low VF and thermal stability are critical.
FAQ
What is the electrical relationship between pin 1, pin 2 (tab), and pin 3?
Pin 1 and pin 3 are independent anode terminals; pin 2 (the metal tab) is the common cathode electrically connected to both internal die cathodes. The tab must be electrically isolated from heatsinks unless the system design intentionally references the cathode to chassis ground.
Does SBR30A120CT-G-E1 support surface-mount assembly?
No - this part uses the through-hole TO-220AB package with bent leads designed for wave or selective soldering. It is not compatible with standard SMT reflow processes due to lead geometry and thermal mass; alternative SMT packages like D2PAK are not offered for this specific SBR variant.
How does its soft switching behavior impact EMI filter design?
The controlled reverse recovery (no abrupt current collapse) reduces high-frequency spectral content above 30 MHz, allowing smaller Y-capacitors and shorter ferrite bead traces in EMI filters - verified in Diodes' AN-7001 application note for 100–500 kHz SMPS designs.
Is the "-G" suffix reflected in the device marking?
Yes - units marked "SBR30A120CT-G" on the top surface confirm green molding compound compliance; the "-E1" suffix denotes tape-and-reel packaging per Diodes' internal ordering convention and does not appear in laser marking.
