Diodes Incorporated MBR2060CT-LJ

Overview

MBR2060CT-LJ from Diodes Incorporated is a dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 60 V peak reverse voltage and 10 A average forward current per leg (20 A total), with maximum forward voltage drop of 0.81 V at 10 A and +25°C. It serves as a low-loss recirculating diode in DC-DC converters and polarity protection device in industrial power supplies.

For engineers reviewing the MBR2060CT-LJ datasheet, MBR2060CT-LJ pinout, MBR2060CT-LJ application, or MBR2060CT-LJ equivalent, key selection criteria include forward voltage at high junction temperature, thermal resistance to case (2°C/W), surge current capability (180 A), and RoHS-compliant lead-free finish on matte tin terminals.

Technical Context

This dual-diode configuration shares a common cathode terminal, enabling synchronous rectification in center-tapped transformer designs and bidirectional clamping in flyback snubbers. Its guard ring die construction suppresses edge breakdown and improves reliability under repetitive surge stress.

Designed for commercial-grade power conversion, it operates across -55°C to +150°C junction temperature range with 0.1 mA max reverse leakage at rated 60 V and +25°C. Thermal performance is optimized for mounting on standard heatsinks (45 mm × 20 mm × 12 mm) per Diodes Incorporated layout guidelines.

FAQ

Is MBR2060CT-LJ pin-compatible with MBR2045CT-LJ?

Yes - both share identical TO-220AB (Type C) package, common-cathode pinout (Anode–Cathode–Anode), and mechanical dimensions. The only functional difference is VRRM: 60 V vs. 45 V. Substitution requires verifying reverse voltage margin in the target circuit.

What is the maximum recommended PCB copper area for thermal relief?

Diodes Incorporated specifies a minimum pad layout on a 45 mm × 20 mm × 12 mm heatsink. For standalone PCB mounting, use ≥400 mm² of 2-oz copper connected directly to the tab (pin 2), with thermal vias to inner ground planes to achieve effective RθJA ≤ 15°C/W.

Does MBR2060CT-LJ support reflow soldering?

Yes - its matte tin finish and TO-220AB package are qualified for lead-free reflow per J-STD-020. Peak temperature must not exceed 260°C for ≤30 seconds; preheat ramp rate ≤3°C/s; and time above 217°C limited to 60–150 seconds.

How does leakage current change at elevated temperature?

At +125°C and rated 60 V reverse bias, IR rises to 15 mA max - a 150× increase over the 0.1 mA limit at +25°C. This must be accounted for in high-temperature standby circuits where leakage could affect quiescent current or bias network stability.
