Diodes Incorporated SBRT60U100CT

Overview

SBRT60U100CT from Diodes Incorporated is a dual common-cathode Trench Schottky Barrier Rectifier optimized for high-efficiency DC-DC and AC-DC power conversion. It delivers 30 A average forward current per leg, 100 V peak repetitive reverse voltage, and ultra-low 0.78 V max forward voltage at 30 A / +25°C - enabling reduced conduction loss and cooler operation in freewheeling and output rectification roles.

For engineers reviewing the SBRT60U100CT datasheet, SBRT60U100CT pinout, SBRT60U100CT application, or SBRT60U100CT equivalent, key selection criteria include its dual-leg TO-220AB package thermal performance (RθJC = 1 °C/W), low IR of 300 µA at 100 V / +125°C, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This device implements a trench-structured Schottky barrier architecture to minimize forward voltage while maintaining stable reverse leakage across temperature. Its dual common-cathode configuration supports independent or paralleled leg operation in synchronous rectifier and freewheel diode topologies.

Designed for high-temperature stability, it sustains rated current up to +150°C junction temperature with only 20% derating at +125°C ambient (per Figure 5), and exhibits <0.72 V VF at 30 A / +125°C - critical for thermally constrained industrial and automotive power supplies.

FAQ

What is the maximum junction temperature for continuous operation?

The SBRT60U100CT supports continuous operation up to +150°C junction temperature, with derating beginning at +125°C ambient (Figure 5). At +125°C ambient, the device maintains 30 A per leg only when mounted on a heatsink meeting the specified thermal conditions (RθJA = 7 °C/W, aluminum 80 × 48 × 35 mm).

Is SBRT60U100CT suitable for synchronous rectification?

Yes - its low forward voltage (0.61 V typ. @ 20 A / +25°C) and fast recovery characteristics make it suitable as a passive synchronous rectifier replacement in medium-frequency (<500 kHz) buck and LLC converters. However, it does not integrate gate drive logic and requires external control for true active synchronous rectification.

How is the common-cathode configuration used in circuit design?

The common-cathode pin (Pin 2) serves as the shared output node for both anodes (Pins 1 and 3). In practice, this enables dual-path rectification - e.g., one leg for primary output and the other for auxiliary rail - or paralleling for higher current, provided trace inductance and thermal coupling are balanced between legs.

Does SBRT60U100CT require a thermal pad or insulator when mounted to a heatsink?

No insulator is required: the TO-220AB package has electrically isolated mounting tab (connected to Pin 2, cathode), allowing direct metal-to-metal heatsink contact. A thermal interface material (e.g., silicone grease or phase-change pad) is recommended to minimize RθJC, but mechanical insulation is unnecessary unless system-level isolation is mandated.
