Diodes Incorporated SBR20150CTFP-JT

Overview

SBR20150CTFP-JT from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 150V peak reverse voltage, with VF ≤ 0.79V at 10A/125°C and IR ≤ 10mA at 150V/125°C, used in high-efficiency AC/DC front-end rectification and DC-DC secondary-side synchronous replacement.

For engineers reviewing the SBR20150CTFP-JT datasheet, SBR20150CTFP-JT pinout, SBR20150CTFP-JT application, or SBR20150CTFP-JT equivalent, key selection criteria include thermal resistance (RθJC = 4°C/W), soft-switching behavior, high-temperature leakage stability, and TO-220AB/ITO-220AB mechanical compatibility in space-constrained power supplies.

Technical Context

This dual-element rectifier integrates two independent 10A-rated super barrier diodes sharing a common cathode terminal, enabling full-wave center-tapped or parallel-output configurations. Its patented super barrier structure replaces conventional PN junctions with low-resistance metal-semiconductor interfaces to reduce forward conduction loss while maintaining high blocking capability.

The device operates across –65°C to +175°C junction temperature range and delivers stable performance under high ambient conditions due to excellent thermal resistance and low IR drift-leakage remains ≤10mA even at 125°C and full 150V reverse bias, supporting reliable operation in industrial and automotive power converters.

FAQ

What is the maximum allowable case temperature for SBR20150CTFP-JT during continuous operation?

The ITO-220AB package supports a maximum case temperature of +175°C, matching its rated junction temperature. With RθJC = 4°C/W, sustained 20A total current requires heatsink temperature ≤135°C to maintain TJ ≤175°C. Derating curves in Figure 5 confirm linear ambient derating above 50°C ambient.

Can SBR20150CTFP-JT be used as a direct replacement for MBR20150CT in existing designs?

Yes, pin-compatible with identical footprint and terminal assignment, but requires verification of thermal margin due to lower VF (0.79V vs. 0.92V) and reduced IR. The insulated tab eliminates need for mica washers, simplifying assembly-but layout must accommodate same isolation clearance as original.

Does the "-JT" suffix indicate a different die or just packaging variation?

The "-JT" suffix denotes an alternate ITO-220AB mechanical variant per Diodes' internal qualification-same SBR die, identical electrical specs, and fully interchangeable with standard SBR20150CTFP. Dimensional tolerances differ slightly (e.g., A = 4.36–4.77mm vs. 4.50–4.90mm), but all critical mounting and thermal interfaces remain compatible.

Is the green molding compound compliant with IPC-4101D and JEDEC J-STD-70B?

Yes-the halogen- and antimony-free compound meets both standards: Br+Cl <1500ppm total (≤900ppm each), Sb <1000ppm, verified per Diodes' material declarations and third-party test reports. RoHS 2 (2011/65/EU) compliance is also certified with all applicable exemptions applied.
