Diodes Incorporated SBR15U100CTL-13

Overview

SBR15U100CTL-13 from Diodes Incorporated is a 15A dual-leg Super Barrier Rectifier in TO252 (DPAK) package, rated for 100V peak repetitive reverse voltage, with ultra-low 0.67V forward voltage at 7.5A/125°C and 100A non-repetitive surge capability; used in high-efficiency AC/DC secondary-side rectification for industrial power supplies and DC-DC converters.

For engineers reviewing the SBR15U100CTL-13 datasheet, SBR15U100CTL-13 pinout, SBR15U100CTL-13 application, or SBR15U100CTL-13 equivalent, key selection criteria include forward voltage at elevated temperature, thermal resistance (1.5°C/W total device), soft switching behavior, and RoHS-compliant matte tin terminations on copper leadframe.

Technical Context

This dual-anode, single-cathode configuration operates as two independent 7.5A legs sharing one cathode terminal, enabling synchronous-like conduction without gate control. Its patented Super Barrier structure achieves lower VF than Schottky diodes while maintaining higher Tj max (175°C) and lower IR drift with temperature.

Thermal design leverages low RθJC (2°C/W per leg) and RθJA (1.5°C/W total device), supported by TO252's exposed thermal pad. Soft recovery minimizes EMI in high-frequency SMPS designs, and leakage remains under 10mA at 100V/125°C - critical for hold-up time integrity in offline converters.

Key Specifications

Pinout & Package

Package: TO252 (DPAK), surface-mount, with exposed thermal pad on underside and three terminals: Pin 1 (Anode 1), Pin 2 (Anode 2), Pin 3 (Cathode). Molded plastic case meets UL 94V-0; matte tin over copper leadframe ensures solderability per MIL-STD-202.

FAQ

What is the thermal pad connection requirement for SBR15U100CTL-13?

The TO252 package features an exposed thermal pad on the underside that must be soldered to a minimum 100 mm² copper pour on the PCB, connected via ≥4 thermal vias (0.3mm diameter) to internal ground planes. This achieves the specified 1.5°C/W RθJA and prevents junction overheating at full 15A load.

Can SBR15U100CTL-13 be used in place of a single 15A Schottky diode?

No - it is a dual-anode device with two independent 7.5A legs sharing one cathode. It cannot substitute a single-anode 15A diode without circuit redesign. However, it replaces two discrete 7.5A Schottkys with shared cathode routing, reducing footprint and interconnect inductance.

Is the 100A IFSM rating applicable to both legs simultaneously?

Yes - the 100A non-repetitive surge rating applies to the total device, meaning both legs can jointly conduct up to 100A for 8.3ms. Each leg contributes proportionally based on layout symmetry; balanced PCB traces are required to ensure current sharing within ±10%.

Does SBR15U100CTL-13 require snubbers in high-frequency operation?

Snubbers are typically unnecessary due to its soft recovery characteristic, confirmed by low reverse recovery charge and absence of hard turn-off spikes in application waveforms. However, a 100pF/10Ω RC snubber across each anode-cathode may be added if layout-induced ringing exceeds EMI limits at >500kHz switching frequencies.
