Diodes Incorporated SBRT30A60CTFP

Overview

SBRT30A60CTFP from Diodes Incorporated is a 30A dual common-cathode trench super barrier rectifier rated for 60V peak reverse voltage, with max 0.56V forward voltage at 15A/25°C and 0.54V at 15A/125°C, delivering ultra-low conduction loss in high-temperature AC-DC front-end and DC-DC secondary-side rectification.

For engineers reviewing the SBRT30A60CTFP datasheet, SBRT30A60CTFP pinout, SBRT30A60CTFP application, or SBRT30A60CTFP equivalent, key selection criteria include thermal stability of reverse leakage (≤70µA at 125°C), low R_θJC (2.5°C/W for ITO-220AB), and dual-leg parallel current capability up to 30A total in compact through-hole packaging.

Technical Context

This device implements Diodes Inc.'s TrenchSBR technology-using trench-etched silicon structures to suppress minority-carrier injection and reduce stored charge-enabling lower VF than Schottky diodes while maintaining superior high-temperature IR stability versus conventional PN junction rectifiers.

Designed as a dual common-cathode configuration in ITO-220AB, it supports independent leg operation or paralleled output for higher current delivery, with thermal performance validated using a 50mm × 50mm × 23mm aluminum heatsink per leg under continuous 15A DC load.

FAQ

What is the difference between SBRT30A60CTFP and SBRT30A60CT?

The SBRT30A60CTFP uses an ITO-220AB package with electrically isolated tab, enabling direct mounting to grounded heatsinks without insulators. The SBRT30A60CT uses a standard TO-220AB with conductive tab, requiring thermal washers for isolation. Both share identical die and electrical specs, but R_θJC differs: 2.5°C/W (FP) vs. 1°C/W (non-FP).

Can SBRT30A60CTFP replace a standard Schottky rectifier like MBR3060CT?

Yes, in most cases-but only if high-temperature stability and low VF are required. SBRT30A60CTFP offers 0.54V V_F at 125°C versus 0.75V for MBR3060CT, and 70µA vs. 1500µA reverse leakage at same temperature. It is not a drop-in replacement due to different thermal mounting requirements (isolated vs. non-isolated tab).

What is the maximum continuous current per leg with no heatsink?

Without a heatsink, continuous current is limited by junction temperature rise. At 25°C ambient and no airflow, the ITO-220AB's R_θJA exceeds 50°C/W. Derating curves show safe operation below 3A per leg to maintain T_J < 150°C. For 15A operation, the specified 50mm × 50mm × 23mm Al heatsink is mandatory.

Is SBRT30A60CTFP suitable for use in medical equipment?

Yes-its ITO-220AB package provides reinforced insulation (≥2500V RMS) meeting IEC 60601-1 creepage/clearance requirements for Class II medical devices. Diodes Incorporated certifies it as halogen-free, RoHS 2 compliant, and qualified for extended-life applications, though final system-level safety validation remains the customer's responsibility.
