Diodes Incorporated SBRT60U50CT

Overview

SBRT60U50CT from Diodes Incorporated is a 60A dual common-cathode Trench Super Barrier Rectifier (SBR) in TO-220AB package, rated for 50V peak repetitive reverse voltage, 30A average forward current per leg, and maximum 0.52V forward voltage at 30A/25°C. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters operating under high-temperature conditions.

For engineers reviewing the SBRT60U50CT datasheet, SBRT60U50CT pinout, SBRT60U50CT application, or SBRT60U50CT equivalent, key selection criteria include its ultra-low VF at high current, stable <0.7mA IR at 125°C, dual-leg TO-220AB thermal performance (RθJC = 1°C/W), and RoHS-compliant green packaging-critical for power supply efficiency and thermal reliability validation.

Technical Context

This dual-diode rectifier integrates two independent Trench Super Barrier die in a single TO-220AB package with common cathode configuration, enabling synchronous rectification or dual-output DC-DC topologies. Its trench-based super barrier architecture delivers lower forward voltage than standard Schottky diodes while maintaining superior high-temperature leakage stability compared to conventional fast recovery diodes.

The device operates across -55°C to +150°C junction temperature range and supports non-repetitive surge currents up to 350A (8.3ms half-sine). Thermal resistance of 1°C/W (junction-to-case) requires heatsink mounting for sustained 60A total conduction, with derating applied for capacitive loads per specification.

FAQ

What is the thermal resistance from junction to case for SBRT60U50CT?

The typical thermal resistance from junction to case (RθJC) is 1°C/W per leg, measured with HK1 heatsink (37mm × 55mm × 15mm). This value assumes proper mounting torque (0.5–0.7 N·m) and flat, clean heatsink surface contact. Derating is required above 25°C ambient per Figure 5 in DS37054 Rev. 3-2.

Can SBRT60U50CT be used in capacitance-input filter circuits?

No-capacitance-input filters require 20% derating of IO per datasheet Note. The rated 30A per leg applies only to resistive or inductive loads. For capacitor-input rectifiers, maximum continuous current must be reduced to 24A per leg to prevent overheating and premature failure due to peak current stress.

Is SBRT60U50CT pin-compatible with standard TO-220AB dual diodes?

Yes-SBRT60U50CT uses industry-standard TO-220AB pinout: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. Mechanical dimensions match AP02002 outline, ensuring drop-in replacement in existing PCB footprints designed for MBR60xxCT or STPS60HxxCG series devices.

Does SBRT60U50CT meet automotive AEC-Q101 requirements?

No-SBRT60U50CT is not AEC-Q101 qualified. While it operates from -55°C to +150°C and is used in automotive auxiliary systems, it lacks the stress testing, failure analysis, and qualification documentation required for AEC-Q101.
