Diodes Incorporated SBR60A150CT

Overview

SBR60A150CT from Diodes Incorporated is a 60A dual common-cathode super barrier rectifier in TO220AB package, rated for 150V peak repetitive reverse voltage and optimized for high-efficiency AC/DC and DC/DC power conversion. It delivers 0.86V typical forward voltage at 30A and 25°C, operates up to +175°C junction temperature, and exhibits soft, fast switching with low leakage (0.05mA typical at 150V, 25°C). It is used in server power supplies and telecom rectifier modules.

For engineers reviewing the SBR60A150CT datasheet, SBR60A150CT pinout, SBR60A150CT application, or SBR60A150CT equivalent, key selection criteria include per-leg forward current rating (30A), thermal resistance (1.2°C/W junction-to-case), soft-switching behavior, RoHS-compliant lead-free finish, and TO220AB mechanical compatibility with standard heatsinks.

Technical Context

The SBR60A150CT integrates two independent 150V/30A rectifying elements in a single TO220AB package with common cathode configuration, enabling dual-output or interleaved converter topologies. Its patented Super Barrier Rectifier (SBR®) technology replaces conventional PN junctions with engineered metal-semiconductor barriers to reduce forward voltage while maintaining high-temperature stability and low leakage.

Thermal performance is defined by R_θJC = 1.2°C/W per leg when mounted on a specified black aluminum heatsink (50mm × 30mm × 23mm), supporting continuous operation at full 60A total device current under forced-air or heatsink-cooled conditions. The device's soft recovery minimizes EMI in high-frequency switching applications such as phase-shifted full-bridge converters.

Compared with VS-60CPH15 and MUR6015CT, the SBR60A150CT uniquely balances low V_F (0.86V), soft recovery, and common-cathode TO220AB compatibility-making it optimal for space-constrained, thermally demanding 100–250kHz power supplies where conduction loss and EMI co-design are critical.

Availability

SBR60A150CT is available at Aetrix Electronics and suitable for server power supplies, telecom rectifier modules, and industrial motor drive DC link circuits requiring stable component supply, long-term lifecycle assurance, and RoHS-compliant manufacturing.

Supply support for SBR60A150CT includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The SBR® product line was developed specifically for high-efficiency, high-reliability power conversion in computing, communications, and industrial equipment-emphasizing low-loss rectification without sacrificing thermal robustness or EMI performance.

FAQ

Is the metal tab of the SBR60A150CT electrically connected to the cathode?

Yes, the metal tab is internally connected to the common cathode terminal (Lead 2). This is confirmed in the TO220AB pin-out diagram and mechanical drawings in DS31133 Rev. 7–2, page 3. Mounting the device to a heatsink therefore ties the cathode to chassis ground unless insulated mounting hardware is used.

What is the maximum average current per leg at 100°C ambient temperature?

Per Figure 3 in DS31133 Rev. 7–2, the derated average forward current per leg is approximately 18A at 100°C ambient with the specified heatsink. This assumes R_θJA = 10°C/W per element and T_J ≤ 175°C, resulting in ~75°C junction rise above ambient.

Does the SBR60A150CT require a gate resistor or external snubber circuit?

No. As a passive rectifier with soft, fast switching characteristics, the SBR60A150CT does not require gate resistors (it has no gate) and typically eliminates the need for RC snubbers in 100–250kHz applications, as verified by EMI testing in Diodes' application note AP02011 for SBR-based telecom rectifiers.

How does the "Green" designation affect soldering profile compliance?

The "Green" status confirms halogen- and antimony-free molding compound and lead-free terminations meeting J-STD-020D moisture sensitivity level 1. Standard Pb-free reflow profiles (peak 260°C, 10s max) apply; no special pre-bake or extended soak is required per Diodes' packaging specification AP02002.
