Diodes Incorporated SBR10150CTFP-JT

Overview

SBR10150CTFP-JT from Diodes Incorporated is a 150V, 10A dual common-cathode super barrier rectifier in ITO-220AB package, designed for high-efficiency AC/DC and DC/DC power conversion where low forward voltage (0.79V @ 5A, 125°C) and soft switching reduce conduction loss and EMI. It delivers 120A non-repetitive surge current and operates from −65°C to +150°C, targeting industrial switch-mode power supplies and server VRMs.

For engineers reviewing the SBR10150CTFP-JT datasheet, SBR10150CTFP-JT pinout, SBR10150CTFP-JT application, or SBR10150CTFP-JT equivalent, key selection criteria include its 0.69–0.92V VF range across temperature, 2mA IR max at 150V/125°C, 4°C/W junction-to-case thermal resistance, and ITO-220AB isolation rating of 2000VAC - critical for high-reliability offline power stages.

Technical Context

This dual-leg super barrier rectifier uses Diodes Inc.'s patented SBR® technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature leakage stability. Its common-cathode configuration supports center-tapped transformer full-wave rectification and synchronous rectifier replacement in isolated topologies.

The device features soft, fast reverse recovery (no data sheet trr value, but characterized by low stored charge and minimal ringing), enabling reduced snubber losses in high-frequency converters. Its ITO-220AB package provides electrical isolation between terminals and heatsink, supporting direct mounting to grounded metal chassis without insulating hardware.

FAQ

What is the maximum junction temperature and how does it affect derating?

The SBR10150CTFP-JT has an operating junction temperature range of −65°C to +150°C. At 150°C, its average forward current derates to approximately 3.5A (per leg) due to thermal resistance and VF/IR trade-offs. Derating curves in Figure 4 of DS30962 show linear reduction from 5A at 25°C ambient to 3.5A at 100°C ambient with standard heatsinking.

Is the ITO-220AB tab electrically isolated from all pins, and what is the isolation test condition?

Yes, the ITO-220AB tab is fully isolated from Pins 1, 2, and 3. The isolation rating is 2000VAC for 3 seconds, measured between any terminal and the heatsink-mounting surface. This is verified per JEDEC standards and enables direct mounting to grounded metal enclosures without insulating pads or hardware.

How does the SBR10150CTFP-JT differ from the SBR10150CT variant?

The SBR10150CTFP-JT uses the ITO-220AB package with isolated tab and 2000VAC rating, whereas SBR10150CT uses standard TO-220AB with electrically connected tab. Both share identical die, VF, IR, and thermal specs, but only the ITO version supports isolated mounting - critical for safety-certified power supplies.

Can this device replace a standard 10A Schottky in existing designs without layout changes?

Yes, the ITO-220AB footprint matches TO-220AB mechanical dimensions, allowing drop-in replacement. However, because the tab is isolated, thermal vias or heatsink mounting must be re-evaluated: no insulator is needed, but thermal interface material must cover the full tab area to maintain 4°C/W RθJC performance.
