Diodes Incorporated SBR20U60CTFP-G

Overview

SBR20U60CTFP-G from Diodes Incorporated is a 20A, 60V Super Barrier Rectifier in ITO-220AB package, optimized for high-efficiency AC/DC and DC/DC power conversion. It delivers low forward voltage (0.47 V at 10 A, 25°C), soft fast switching, and stable operation up to +150°C junction temperature-used in server power supplies, industrial SMPS, and telecom rectifiers.

For engineers reviewing the SBR20U60CTFP-G datasheet, SBR20U60CTFP-G pinout, SBR20U60CTFP-G application, or SBR20U60CTFP-G equivalent, key selection criteria include forward voltage drop at 10–20 A, thermal resistance (R_θJC = 4°C/W), peak surge rating (200 A), reverse leakage (<0.5 mA at 60 V, 25°C), and RoHS/Green compliance status.

Technical Context

This dual-common-cathode super barrier rectifier replaces conventional Schottky diodes in medium-power applications where higher reverse voltage capability and improved high-temperature leakage performance are required. Its patented structure enables lower VF than standard Schottkys while maintaining <100 µA leakage at 125°C and 60 V.

The device operates with soft recovery characteristics-minimizing EMI in high-frequency switching topologies-and supports continuous conduction mode (CCM) operation in PFC stages and synchronous rectification in secondary-side outputs of isolated converters.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, serving industrial, computing, communications, and consumer markets with high-reliability components.

The SBR® Super Barrier Rectifier product line targets high-efficiency power conversion where Schottky limitations in voltage rating and high-temperature leakage must be overcome without resorting to slower, higher-VF PN diodes.

FAQ

What is the maximum allowable case temperature for continuous operation?

The SBR20U60CTFP-G is rated for continuous average rectified current of 20 A at T_C = +110°C. Exceeding this temperature requires derating per Figure 1 in DS30976; operation above +110°C case temperature risks irreversible degradation of forward voltage and leakage performance.

Does the ITO-220AB package provide electrical isolation between the tab and pins?

Yes-the ITO-220AB package provides 2000 V_AC isolation (3 seconds) between the metal tab and all three terminals. This allows direct mounting to a grounded heatsink without insulating hardware, reducing thermal resistance and assembly complexity in safety-isolated power supplies.

How does the SBR20U60CTFP-G compare to standard Schottky rectifiers in high-temperature operation?

At +125°C and 60 V reverse bias, SBR20U60CTFP-G exhibits ≤100 µA leakage-over 100× lower than typical 60 V Schottkys (which exceed 10 mA). Its patented super barrier structure maintains low VF (0.57 V @ 10 A) even at elevated temperatures, preserving efficiency in thermally constrained enclosures.

Can SBR20U60CTFP-G be used in place of TO-220AB-packaged equivalents like SBR20U60CT-G?

Yes-SBR20U60CTFP-G shares identical electrical specifications and pinout with SBR20U60CT-G but uses the ITO-220AB package with isolated tab. Mechanical compatibility requires verifying heatsink clearance and mounting hole alignment; thermal design must account for R_θJC = 4°C/W (vs. 2°C/W for TO-220AB).
