Product details
Overview
SBR30A120CTFP-JT from Diodes Incorporated is a 120V, 30A dual common-cathode super barrier rectifier in ITO-220AB package, engineered for high-efficiency AC/DC and DC/DC power conversion. It delivers VF = 0.78 V at 15 A / 25°C, supports 175°C junction operation, and exhibits soft fast switching with IFSM = 250 A (8.3 ms), targeting server PSUs and telecom rectifiers.
For engineers reviewing the SBR30A120CTFP-JT datasheet, SBR30A120CTFP-JT pinout, SBR30A120CTFP-JT application, or SBR30A120CTFP-JT equivalent, key selection criteria include forward voltage consistency across temperature, reverse leakage stability at 125°C, thermal resistance (RθJC = 4°C/W), and isolation rating (2000 VAC) for heatsink-mounted safety-critical designs.
Technical Context
This dual-leg super barrier rectifier integrates two anode terminals sharing one cathode terminal, enabling synchronous half-bridge or dual-phase output configurations. Its patented SBR technology replaces conventional Schottky architecture to reduce forward voltage while maintaining low IR at elevated temperatures.
Designed for high-reliability industrial and telecom power supplies, it operates up to 175°C junction temperature with 2000 VAC isolation between terminals and heatsink - a critical requirement for ITO-220AB-based insulated mounting in 48 V intermediate bus converters and redundant PSU modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - Maximum repetitive reverse voltage per leg; defines safe blocking capability in 48 V–60 V output rectification stages. |
| IO (per leg) | 15 A - Continuous average forward current per anode leg; enables 30 A total device output with balanced dual-leg layout. |
| VF @ 15 A, 25°C | 0.78 V - Measured forward drop; directly reduces conduction loss by ~15% vs. standard Schottky diodes at same current. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance (ITO-220AB); determines heatsink sizing for 175°C max TJ under 30 A load. |
| IR @ 120 V, 125°C | 20 μA - Reverse leakage at full voltage and high temperature; ensures minimal standby loss in hot-running telecom systems. |
| IFSM | 250 A - Non-repetitive surge rating (8.3 ms); withstands inrush currents during cold-start of high-capacitance output rails. |
| VAC Isolation | 2000 V - AC isolation rating (3 sec); certifies safe terminal-to-heatsink insulation for grounded heatsink mounting. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab, UL 94V-0 molded plastic case, matte tin-plated copper leadframe, and 1.65 g mass. Designed for direct heatsink mounting without insulating washers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First anode connection | Carries forward current from first input phase or leg; electrically isolated from tab and cathode. |
| 2 (Cathode) | Common cathode node | Shared return path for both anode legs; connects to output rail or ground reference in center-tapped or dual-output topologies. |
| 3 (Anode B) | Second anode connection | Carries forward current from second input phase or leg; independent of Anode A but referenced to same cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR technology | Enables lower VF than Schottky diodes while suppressing thermal runaway at >125°C junction temperature. |
| Soft fast switching | Reduces EMI generation during turn-off; eliminates need for snubbers in 100–300 kHz SMPS designs. |
| 175°C operating junction | Supports compact thermal design in sealed enclosures or high-ambient environments like base station power modules. |
| 2000 VAC isolation | Permits direct mechanical mounting to grounded heatsinks without dielectric pads-reducing thermal impedance by ~0.8°C/W. |
| Halogen & antimony free | Meets IPC-1752A Class 3 requirements; <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - compliant for automotive and industrial green procurement. |

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-30CPH07-M3 | 70 V VRRM, 30 A IO, TO-247AC package, RθJC = 1.5°C/W, no isolation rating | Lacks 2000 VAC isolation; requires insulating hardware for heatsink mounting | Select when higher thermal performance is prioritized over isolation and board space is constrained. |
| ON Semiconductor MUR3020CT | 200 V VRRM, 30 A IO, TO-220AB (non-isolated), VF = 1.1 V @ 15 A, RθJC = 2°C/W | Higher VF increases conduction loss by ~0.48 W/leg; no isolation; lower max TJ (175°C same) | Choose only if 200 V blocking is mandatory and thermal budget permits higher drop. |
Compared with VS-30CPH07-M3 and MUR3020CT, SBR30A120CTFP-JT uniquely combines 120 V blocking, 2000 VAC isolation, and sub-0.8 V forward drop - making it optimal for insulated, space-constrained, high-efficiency 48 V telecom/server rectifiers where thermal and safety margins are tightly coupled.

FAQ
What is the difference between SBR30A120CTFP-JT and SBR30A120CTFP?
SBR30A120CTFP-JT specifies the ITO-220AB (Alternate) mechanical outline per Diodes' DS31094 Rev. 6–2, with dimensional tolerances updated for Date Code 0733 and newer. The "-JT" suffix denotes this alternate ITO-220AB variant, which maintains identical electrical specs, thermal resistance, and isolation rating but uses revised mold cavity dimensions for improved manufacturability and leadframe coplanarity.
Can SBR30A120CTFP-JT be used in place of a standard Schottky diode?
Yes, provided the circuit's blocking voltage (≤120 V), current demand (≤15 A per leg), and thermal environment (≤175°C TJ) align. Its lower VF improves efficiency, but its soft recovery differs from abrupt Schottky turn-off - verify EMI behavior in high-frequency layouts. It is not a direct drop-in for non-isolated TO-220AB packages due to insulated tab requirements.
Is the cathode pin electrically isolated from the heatsink tab?
No - the cathode (Pin 2) is electrically connected to the metal tab in the ITO-220AB package. However, the tab itself is electrically isolated from the PCB mount surface via internal molding. When mounted to a grounded heatsink, the cathode becomes chassis-ground referenced, requiring appropriate system-level grounding strategy.
Does SBR30A120CTFP-JT require derating at high ambient temperatures?
Yes - maximum average current must be reduced per the thermal derating curve in DS31094. At 100°C ambient with 4°C/W RθJC and 25°C heatsink rise, TJ reaches 125°C, limiting IO to ~12 A per leg. Full 30 A total output is only sustainable below 40°C ambient with adequate heatsinking and airflow.
