Product details
Overview
SBR30A150CTFP-JT from Diodes Incorporated is a 30A dual common-cathode super barrier rectifier in ITO-220AB package, rated for 150V peak repetitive reverse voltage, with typical forward voltage of 0.74V at 15A/25°C and thermal resistance of 4°C/W (junction-to-case). It delivers soft, fast switching with low leakage (<0.1mA at 150V/25°C) and operates from –65°C to +175°C, targeting high-efficiency AC/DC front-end and DC-DC secondary-side rectification.
For engineers reviewing the SBR30A150CTFP-JT datasheet, SBR30A150CTFP-JT pinout, SBR30A150CTFP-JT application, or SBR30A150CTFP-JT equivalent, key selection criteria include forward voltage drop at elevated temperature, surge current capability (250A IFSM), isolation rating (2000VAC), and RoHS-compliant green packaging with halogen/antimony-free molding compound.
Technical Context
This dual-anode, single-common-cathode rectifier integrates two independent 15A legs sharing one cathode terminal, enabling synchronous or interleaved secondary-side rectification in center-tapped or full-wave configurations. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces, reducing forward voltage while maintaining high-temperature leakage stability.
The device uses an isolated ITO-220AB package with electrically insulated tab (2000VAC isolation), allowing direct heatsink mounting without insulating hardware. Thermal performance is optimized for high ambient operation, with derated average current dropping linearly from 30A at 25°C to ~10A at 125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage before breakdown; sets usable input voltage range in 115/230VAC SMPS designs. |
| IO (per leg) | 15 A - Continuous DC output current per anode leg; supports 30A total dual-leg conduction in parallel-path topologies. |
| VF @ 15A/25°C | 0.74 V - Low conduction loss improves efficiency in high-current secondary-side rectification (e.g., 12V/20A outputs). |
| IFSM | 250 A - Peak non-repetitive surge current handling; withstands inrush and transient overloads without failure. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; enables predictable heatsink sizing for forced or natural convection cooling. |

FAQ
What is the difference between SBR30A150CTFP-JT and SBR30A150CTFP?
The "-JT" suffix denotes an alternate ITO-220AB package variant introduced after Date Code 0733 (week 33, 2007), conforming to updated mechanical dimensions per AP02002 specification. Electrically and thermally identical, it ensures backward compatibility while aligning with revised mold-line tolerances and leadframe plating consistency.
Can SBR30A150CTFP-JT be used in place of a standard TO-220AB Schottky rectifier?
Yes, but only if the PCB footprint matches ITO-220AB (not TO-220AB), and isolation requirements are verified. Its insulated tab eliminates need for insulating hardware, unlike conductive-tab TO-220AB devices. Electrical substitution requires confirming VF, IFSM, and thermal derating curves match system needs.
Does this part meet automotive AEC-Q101 qualification?
No. SBR30A150CTFP-JT is not AEC-Q101 qualified. Diodes Incorporated offers AEC-Q101 variants under the SBR-A series (e.g., SBR30A150CTFP-13), which undergo additional stress testing including HTGB, TCT, and UHAST. This part is intended for industrial and commercial applications.
What is the maximum recommended heatsink temperature for continuous 30A operation?
At 30A total (15A per leg), junction temperature must stay ≤175°C. With RθJC = 4°C/W and typical RθCS + RθSA ≈ 1.5°C/W, max heatsink temperature is ~110°C ambient-equivalent. For reliable long-term operation, limit heatsink temperature to ≤85°C to maintain >10-year lifetime per Arrhenius modeling at 125°C TJ.
