Diodes Incorporated SBR20A60CTFP

Overview

SBR20A60CTFP from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 60V peak reverse voltage and featuring 0.56V typical forward voltage at 20A/25°C. It delivers soft fast switching, high-temperature stability up to +150°C, and 2000V isolation between terminals and heatsink - deployed in automotive DC-DC converters and industrial power supplies where low conduction loss and thermal robustness are critical.

For engineers reviewing the SBR20A60CTFP datasheet, SBR20A60CTFP pinout, SBR20A60CTFP application, or SBR20A60CTFP equivalent, key selection criteria include forward voltage at 20A, leakage current at 125°C, thermal resistance (4°C/W junction-to-case), isolation rating, and AEC-Q101 qualification status for automotive-grade reliability.

Technical Context

This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces, reducing forward voltage while maintaining low leakage and soft recovery characteristics.

The ITO-220AB package provides enhanced thermal performance over standard TO-220AB via insulated mounting (2000V AC isolation) and optimized copper leadframe design. Electrical behavior remains consistent across temperature: VF increases only marginally from 0.56V @ 25°C to 0.79V @ 25A/125°C, and IR stays ≤100µA at 60V/125°C.

FAQ

What is the maximum junction temperature for SBR20A60CTFP?

The absolute maximum junction temperature is +150°C, with continuous operation supported from –65°C to +150°C. Derating begins above +25°C ambient: at +100°C ambient, the device sustains 10A per leg with RθJA = 16°C/W, verified per Figure 1 in DS30965 Rev. 12–2.

Does SBR20A60CTFP require a thermal pad or insulator when mounted to a heatsink?

No. The ITO-220AB package provides 2000V AC isolation between the cathode tab and heatsink, eliminating the need for mica or silicone insulators. Direct mounting with thermal paste is recommended to maintain the specified 4°C/W RθJC.

How does SBR20A60CTFP differ from standard Schottky rectifiers?

Unlike conventional Schottkys, SBR20A60CTFP uses a patented super barrier structure that suppresses reverse leakage at high temperature (≤100µA @ 125°C) while maintaining low VF (0.56V @ 20A/25°C). This avoids the trade-off between VF and IR inherent in metal-semiconductor junctions.

Is SBR20A60CTFP suitable for use in life support equipment?

No. Diodes Incorporated explicitly prohibits use of SBR20A60CTFP in life support devices or systems without express written approval from its CEO, as stated in the "LIFE SUPPORT" notice on page 7 of DS30965 Rev. 12–2.
