Diodes Incorporated SBRT20U60SP5-13D

Overview

SBRT20U60SP5-13D from Diodes Incorporated is a 20A, 60V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, delivering ultra-low 0.48V forward voltage at 20A/25°C and <0.4mA reverse leakage at 60V/25°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC-DC adapters and DC-DC converters.

For engineers reviewing the SBRT20U60SP5-13D datasheet, SBRT20U60SP5-13D pinout, SBRT20U60SP5-13D application, or SBRT20U60SP5-13D equivalent, key selection criteria include thermal resistance (RθJL = 2°C/W), low-profile 1.1mm height, AEC-Q101 qualification, and stable IR performance up to +150°C ambient.

Technical Context

This SBR uses trench-based super barrier technology to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability versus conventional Schottkys. Its 60V VRRM rating targets secondary-side rectification in ≤12V output power supplies.

The POWERDI®5 package enables direct PCB thermal conduction via exposed leadframe, achieving RθJL = 2°C/W - critical for high-current, space-constrained applications where heatsinking is impractical.

FAQ

What is the maximum junction temperature for SBRT20U60SP5-13D?

The device is rated for TJ from –55°C to +150°C. At 20A continuous current with RθJL = 2°C/W and 25°C lead temperature, junction temperature reaches ~65°C - well within safe operating range. Derating begins above 125°C ambient per Figure 5.

Is SBRT20U60SP5-13D pin-compatible with standard SOD-123 or SMA packages?

No - it uses the proprietary POWERDI®5 package with three terminals (Anode, Cathode, Exposed Pad). Footprint and soldering requirements differ significantly from SOD-123 or SMA; AP02001 pad layout must be followed for reliable thermal performance.

Does SBRT20U60SP5-13D require a heatsink for 20A operation?

No external heatsink is required. With proper PCB copper area (50mm×50mm×23mm heatsink per datasheet note), the 2°C/W RθJL enables full 20A operation at +75°C ambient. The exposed pad must be soldered to ≥1 cm² of 2-oz copper for specified thermal performance.

How does SBRT20U60SP5-13D compare to Schottky diodes in reverse leakage at high temperature?

At 60V and +125°C, SBRT20U60SP5-13D exhibits 80mA IR - significantly lower than typical 20A Schottkys (often >200mA). This stability prevents thermal runaway in sealed enclosures and improves long-term reliability in automotive and industrial environments.
