Diodes Incorporated SBRT25U50SLP-13

Overview

SBRT25U50SLP from Diodes Incorporated is a 25A, 50V Trench Super Barrier Rectifier (SBR) in the POWERDI5060-8 package, engineered for high-efficiency DC-DC converters and AC-DC adapters. It delivers ultra-low forward voltage (0.43 V @ 25 A, +125°C), <0.5 mA reverse leakage at 50 V/+125°C, and thermal resistance of 1 °C/W junction-to-case - enabling compact, thermally robust power stage designs.

For engineers reviewing the SBRT25U50SLP datasheet, SBRT25U50SLP pinout, SBRT25U50SLP application, or SBRT25U50SLP equivalent, key selection criteria include forward voltage stability across temperature, reverse leakage performance at +125°C, junction-to-case thermal resistance, and compatibility with thin-profile PCB layouts requiring ≤1.1 mm height.

Technical Context

This TrenchSBR rectifier uses proprietary trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability. Its structure suppresses thermal runaway by limiting reverse leakage to ≤0.5 mA at full-rated VR and +125°C.

The device operates across –55°C to +150°C junction temperature, supports 200 A non-repetitive surge current (8.3 ms half-sine), and is qualified to AEC-Q101 - confirming suitability for automotive-grade power conversion where reliability under thermal stress is critical.

Key Specifications

Pinout & Package

Packaged in the surface-mount POWERDI5060-8 (5.0 × 6.0 mm, 1.1 mm max height), this 2-terminal device features an exposed thermal pad on the bottom side for enhanced heat dissipation. Polarity is marked with cathode band on top surface.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The SBRT25U50SLP has a rated junction temperature range of –55°C to +150°C. For continuous operation at full 25 A current, thermal design must ensure TJ does not exceed +150°C - achievable with RθJA ≤ 10°C/W using recommended Al substrate layout per datasheet Note 5.

Is the POWERDI5060-8 package lead-free and RoHS compliant?

Yes. The SBRT25U50SLP features a matte tin annealed finish over copper leadframe and is fully RoHS compliant per EU Directive 2011/65/EU, with halogen- and antimony-free "Green" molding compound meeting <900 ppm Br, <900 ppm Cl, and <1000 ppm Sb limits.

How does its reverse leakage compare to standard Schottky diodes at +125°C?

At VR = 50 V and TJ = +125°C, SBRT25U50SLP exhibits ≤0.5 mA IR - typically 5–10× lower than comparable 25 A Schottky diodes, which often exceed 2–5 mA under identical conditions, significantly reducing thermal runaway risk.

Can it replace a TO-220 rectifier in an existing design?

Yes, but with layout adaptation: the POWERDI5060-8 is surface-mount and requires re-optimization of thermal pads and copper pour. Its 1 °C/W RθJC enables better thermal transfer than TO-220's typical 2–3 °C/W, but mechanical mounting and creepage/clearance must be revalidated per IPC-2221.
