Diodes Incorporated SBR30200CTFP

Overview

SBR30200CTFP from Diodes Incorporated is a 30A dual common-cathode super barrier rectifier in ITO-220AB package, rated for 200V peak repetitive reverse voltage, with 0.88V typical forward voltage at 15A/125°C and 24ns typical reverse recovery time. It delivers low conduction loss and soft switching in high-frequency DC/DC output stages of industrial power supplies.

For engineers reviewing the SBR30200CTFP datasheet, SBR30200CTFP pinout, SBR30200CTFP application, or SBR30200CTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), avalanche energy capability (10,000W peak pulse), leakage current (<0.1mA at 200V/25°C), and RoHS-compliant green molding compound construction.

Technical Context

This dual-leg super barrier rectifier integrates two independent 15A-rated anode terminals sharing a single cathode terminal, enabling synchronous half-wave rectification in center-tapped or dual-output topologies. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to suppress minority-carrier injection.

The device operates across –65°C to +175°C junction temperature range and sustains 2000V isolation between terminals and heatsink-critical for reinforced insulation in AC-DC front-end designs. Soft switching behavior minimizes EMI generation during turn-off transitions under high di/dt conditions.

FAQ

What is the maximum continuous junction temperature for SBR30200CTFP?

The absolute maximum junction temperature is +175°C, verified per DS30994 Rev. 7–2. Operation at this limit requires strict thermal design: with RθJC = 4°C/W and a 25°C heatsink, maximum allowable power dissipation is 37.5W. Derating curves in Figure 5 confirm 15A operation is sustainable only below 125°C ambient when using the recommended 45mm × 20mm × 12mm black aluminum heatsink.

Can SBR30200CTFP replace standard Schottky rectifiers in existing designs?

Yes, but with verification: its pinout matches TO-220AB/ITO-220AB footprints, and the 200V VRRM and 30A total rating meet or exceed most MBR30xx equivalents. However, its lower VF and faster trr may alter snubber requirements and EMI filter tuning-especially in >300kHz designs where reduced ringing changes conducted emission profiles.

Does the ITO-220AB package require insulating hardware when mounted to a grounded heatsink?

No insulating hardware is required. The ITO-220AB package provides 2000V AC isolation between the metal tab (cathode) and all leads, as confirmed in the "Isolation Voltage" specification. This allows direct mechanical and thermal attachment to a grounded heatsink while maintaining reinforced insulation-critical for medical and telecom safety certifications.

What does the "-G" suffix indicate in SBR30200CTFP-G?

The "-G" suffix denotes compliance with Diodes Incorporated's Green standard: halogen-free (<900ppm Br+Cl), antimony-free (<1000ppm), and RoHS-compliant. It uses a proprietary green molding compound meeting IPC-4101D and JEDEC J-STD-609B Class 1, distinct from standard epoxy. All SBR30200CTFP units shipped since August 2012 are Green-compliant by default.
