Diodes Incorporated SBR30A60CTFP

Overview

SBR30A60CTFP from Diodes Incorporated is a 60 V, 30 A dual common-cathode Super Barrier Rectifier in ITO-220AB package, optimized for high-efficiency SMPS and DC-DC converters. It delivers VF = 0.60 V max at 15 A/25°C, IR = 0.5 mA max at 60 V/25°C, and features soft fast switching with 400 mJ non-repetitive avalanche energy for robust freewheeling operation.

For engineers reviewing the SBR30A60CTFP datasheet, SBR30A60CTFP pinout, SBR30A60CTFP application, or SBR30A60CTFP equivalent, key selection criteria include forward voltage drop at high temperature, thermal resistance (RθJC = 2°C/W), isolation voltage (2,000 VAC), and UL 1557 certification for safety-critical power stages.

Technical Context

This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous half-wave rectification or dual-output configurations. Its patented super barrier structure replaces traditional PN junctions to reduce forward conduction loss while maintaining low leakage and soft recovery characteristics.

The device operates across –65°C to +150°C junction temperature range and supports 250 A non-repetitive surge current (8.3 ms half-sine). Its 2,000 VAC isolation rating (ITO-220AB only) enables direct heatsink mounting without insulating hardware in isolated topologies.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design and manufacturing operations across Asia and the Americas.

The SBR® Super Barrier Rectifier product line targets high-efficiency, high-reliability power conversion in computing, industrial, and telecom applications where low VF, soft recovery, and thermal robustness are critical.

FAQ

What is the maximum continuous junction temperature for SBR30A60CTFP?

The absolute maximum junction temperature is +150°C, with derated average forward current beginning at +25°C ambient. At 100°C ambient with a 2°C/W heatsink, the device sustains ~15 A per leg continuously, verified by Fig. 5's forward current derating curve and thermal resistance data.

Does SBR30A60CTFP require a thermal pad or insulator when mounted to a heatsink?

No - the ITO-220AB package provides 2,000 VAC isolation between terminals and the metal tab, allowing direct mounting to grounded heatsinks without insulating hardware. This is confirmed in the "Isolation Voltage" specification and Mechanical Data section of DS30982 Rev. 10-2.

How does SBR30A60CTFP differ from standard Schottky rectifiers in high-temperature operation?

Unlike Schottky diodes whose leakage current doubles every ~10°C, SBR30A60CTFP maintains IR ≤60 mA at +125°C (vs. 0.5 mA at +25°C), due to its silicon-based barrier structure. This prevents thermal runaway in enclosed power supplies above 85°C ambient.

Can SBR30A60CTFP be used in place of TO-220AB-packaged SBR30A60CT in existing designs?

Yes - both share identical pinout and electrical specs, but SBR30A60CTFP uses the insulated ITO-220AB package. Mechanical compatibility requires verifying heatsink clearance and mounting hole alignment; the ITO-220AB footprint is dimensionally identical per AP02002 package drawing.
