Diodes Incorporated SBR20U50SLP-13

Overview

SBR20U50SLP from Diodes Incorporated is a 20A, 50V Super Barrier Rectifier (SBR®) in PowerDI5060-8 package, engineered for high-efficiency DC-DC converters and AC-DC adapters. It delivers ultra-low forward voltage (0.46–0.52 V at 10–20 A), <0.5 mA reverse leakage at 50 V/25°C, and stable operation up to +125°C junction temperature.

For engineers reviewing the SBR20U50SLP datasheet, SBR20U50SLP pinout, SBR20U50SLP application, or SBR20U50SLP equivalent, key selection criteria include thermal resistance (R_θJC = 5 °C/W), avalanche ruggedness versus Schottky diodes, low-profile packaging (<1.1 mm height), and JEDEC-qualified reliability for industrial power conversion designs.

Technical Context

This SBR rectifier uses patented Super Barrier technology to achieve lower VF than standard Schottkys while maintaining superior avalanche energy handling-critical for flyback and synchronous rectification circuits where voltage transients occur. Its 57 ns reverse recovery time supports high-frequency switching up to ~1 MHz.

The PowerDI5060-8 package integrates dual anode/cathode terminals with optimized copper leadframe and thermally efficient mold compound, enabling 20 A average current with only 5 °C/W junction-to-case thermal resistance when mounted on appropriate PCB copper area.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

SBR20U50SLP belongs to Diodes' Super Barrier Rectifier product line, developed specifically to replace Schottky diodes in high-efficiency, high-reliability power conversion where low VF and rugged avalanche capability are jointly required.

FAQ

What is the maximum junction temperature for continuous operation?

The SBR20U50SLP is rated for continuous operation from –55°C to +125°C junction temperature. At 20 A average current, thermal design must ensure T_J stays ≤125°C using the specified R_θJC = 5 °C/W and adequate PCB copper area or heatsinking per Figure 5 in DS36243 Rev. 4–2.

Is this part suitable for automotive applications?

The SBR20U50SLP is not AEC-Q200 qualified. For automotive use, Diodes offers the Q-suffix variant SBR20U50SLPQ-13, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities-available separately upon request.

How does its reverse recovery time compare to standard Schottky diodes?

At 57 ns, t_rr is higher than most Schottky diodes (typically <10 ns), but this reflects its hybrid SBR structure that trades minimal recovery charge for vastly improved avalanche ruggedness-making it preferable in circuits subject to voltage spikes, such as flyback snubberless designs.

Can it be used in parallel configurations?

Yes-the PowerDI5060-8's four parallel anode and four parallel cathode terminals provide inherent current-sharing symmetry. Parallel operation is supported when PCB layout maintains matched trace lengths and thermal coupling; derating to 18 A per device is recommended for >2-unit arrays.
