Diodes Incorporated SBR20A150CTFP

Overview

SBR20A150CTFP from Diodes Incorporated is a dual common-cathode Super Barrier Rectifier optimized for high-efficiency DC-DC conversion and freewheeling applications. It delivers 10 A average forward current per leg at 150 V peak reverse voltage, with a maximum forward voltage of 0.82 V at 10 A and 25°C, and leakage current ≤0.1 mA at 150 V and 25°C. Its ITO-220AB package supports thermal dissipation in compact power supplies.

For engineers reviewing the SBR20A150CTFP datasheet, SBR20A150CTFP pinout, SBR20A150CTFP application, or SBR20A150CTFP equivalent, key selection criteria include forward voltage drop at 10 A, thermal resistance (4°C/W junction-to-case), isolation voltage (2,000 VAC), soft switching behavior, and RoHS-compliant green molding compound compatibility with automated reflow assembly.

Technical Context

This dual-diode rectifier integrates two independent SBR® (Super Barrier Rectifier) elements in a single ITO-220AB thermally enhanced package with isolated heatsink tab. Each leg operates as a unidirectional, low-loss power diode featuring patented barrier technology that reduces forward conduction loss while maintaining fast, soft reverse recovery-critical for minimizing EMI in high-frequency switching topologies.

The device is rated for 150 V repetitive reverse voltage and handles non-repetitive surge currents up to 180 A (8.3 ms half-sine). Its thermal design enables operation from –65°C to +175°C junction temperature, with derated forward current above 25°C ambient per Figure 4 in DS30967 Rev. 9–2.

FAQ

What is the maximum junction temperature rating for SBR20A150CTFP?

The absolute maximum junction temperature is +175°C, with continuous operation supported from –65°C to +175°C. Derating begins above 25°C ambient per Figure 4 in DS30967 Rev. 9–2; at 100°C ambient, the device sustains 6.5 A per leg with proper heatsinking.

Is the metal tab electrically isolated in the ITO-220AB package?

Yes-the ITO-220AB variant provides 2,000 VAC isolation between all terminals and the heatsink tab for 3 seconds, verified per datasheet Section "Maximum Ratings." This allows direct mounting to grounded chassis without additional insulation.

How does SBR20A150CTFP differ from standard Schottky rectifiers in reliability?

Unlike conventional Schottkys, SBR20A150CTFP uses a patented barrier structure that prevents thermal runaway under high-temperature reverse bias. Its IR increases only to 10 mA at 125°C (vs. >100 mA for many Schottkys), enabling stable operation in automotive and industrial environments.

Can SBR20A150CTFP be used in place of TO-220AB-packaged equivalents?

No-it uses the ITO-220AB package with isolated tab, whereas TO-220AB variants like SBR20A150CT have electrically connected tabs. Mechanical mounting and thermal interface design must account for the 4°C/W RθJC and isolation requirement; PCB layout cannot reuse TO-220AB footprints without verification.
