Diodes Incorporated SBR30A60CTFP-G

Overview

SBR30A60CTFP-G from Diodes Incorporated is a 60 V, 30 A dual common-cathode Super Barrier Rectifier in ITO-220AB package, featuring 0.60 V max forward voltage at 15 A and 0.5 mA max reverse leakage at 60 V and 25°C. It delivers soft fast switching, high-temperature stability, and UL 1557 certification for use in high-efficiency SMPS and DC-DC converters.

For engineers reviewing the SBR30A60CTFP-G datasheet, SBR30A60CTFP-G pinout, SBR30A60CTFP-G application, or SBR30A60CTFP-G equivalent, key selection criteria include its low VF at high current, 2000 V isolation rating (terminal-to-heatsink), 400 mJ non-repetitive avalanche energy, and green RoHS-compliant construction with halogen/antimony-free molding compound.

Technical Context

This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous freewheeling or dual-output rectification. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to suppress minority-carrier injection, reducing stored charge and enabling soft recovery without snubbers.

The device operates across –65°C to +150°C junction temperature range with 2°C/W junction-to-case thermal resistance when mounted on a heatsink. Its 8.3 ms surge rating of 250 A and 2 kV isolation support robust operation in industrial power supplies subject to line transients and thermal cycling.

FAQ

What is the maximum junction temperature and how does it affect derating?

The SBR30A60CTFP-G has a rated junction temperature range of –65°C to +150°C. At 100°C case temperature, its average forward current drops to 30 A per leg; above that, linear derating applies per Figure 5. With RθJC = 2°C/W, maintaining TC ≤ 100°C requires ≤20 W per leg dissipation - achievable using a 10 cm² aluminum heatsink with 1 m/s airflow.

Does the ITO-220AB package require insulating hardware for heatsink mounting?

Yes - the ITO-220AB package features an electrically isolated tab, but the isolation rating (2000 V AC) assumes proper mounting with non-conductive thermal interface material (e.g., silicone pad or ceramic washer) and no mechanical damage to the plastic body. Mounting screws must not penetrate the isolation layer, and torque must stay within 0.5–0.7 N·m to avoid cracking.

How does SBR technology differ from standard Schottky and fast recovery diodes?

SBR uses a proprietary metal-semiconductor barrier with controlled carrier lifetime, achieving Schottky-level VF (0.60 V) while suppressing reverse recovery charge (Qrr) to near-zero - unlike Schottkys, which suffer from high leakage at >100°C, and unlike fast recovery diodes, which exhibit hard switching and EMI. This enables snubberless operation in high-frequency (>300 kHz) topologies.

Is the SBR30A60CTFP-G suitable for use in automotive applications?

Yes - it meets AEC-Q101 stress test requirements when qualified (SBR30A60CTFP-G is not AEC-Q101 certified, but the SBRT30A60CTFP-G variant is). For non-automotive-grade use in under-hood auxiliary supplies, its 150°C TJ rating, stable IR up to 125°C, and green construction support extended reliability in harsh thermal environments without formal qualification.
