Diodes Incorporated SBRT20M60SP5-13

Overview

SBRT20M60SP5 from Diodes Incorporated is a 20A, 60V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, delivering VF = 0.57 V at 20 A/25°C and IR = 0.18 mA at 60 V/25°C. It serves as a high-efficiency rectifier or freewheeling diode in compact AC-DC adapters and DC-DC converters requiring low conduction loss and stable high-temperature leakage performance.

For engineers reviewing the SBRT20M60SP5 datasheet, SBRT20M60SP5 pinout, SBRT20M60SP5 application, or SBRT20M60SP5 equivalent, key selection criteria include forward voltage drop at full rated current, reverse leakage stability up to +150°C, thermal resistance (RθJC = 2°C/W), compact 1.1 mm profile, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This TrenchSBR device uses proprietary trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining significantly better IR stability at elevated temperatures-critical for high-density power supplies operating near thermal limits. Its structure suppresses minority-carrier injection, enabling fast recovery without soft-recovery trade-offs.

The POWERDI®5 package integrates a thermally optimized copper leadframe with direct die-to-pad thermal path, achieving RθJA = 10°C/W on 2 oz. PCB with heatsink. The 5-pin configuration supports dual-anode or dual-cathode configurations depending on internal die layout, though this variant is single-diode with anode/cathode terminals only.

Key Specifications

Pinout & Package

Packaged in the surface-mount POWERDI®5 case (3.966 mm × 6.504 mm × 1.10 mm), this single-diode rectifier features two active terminals: Anode and Cathode. The package uses a thermally enhanced copper leadframe with exposed thermal pad on the bottom side for PCB-level heat dissipation.

FAQ

What is the maximum junction temperature for continuous operation?

The SBRT20M60SP5 has an operating junction temperature range of –55°C to +150°C. Continuous operation at TJ = +150°C is permitted provided thermal design maintains average junction temperature within this limit using the specified RθJC = 2°C/W and appropriate PCB copper area per datasheet layout guidelines.

Is the thermal pad electrically isolated?

No-the exposed thermal pad on the bottom of the POWERDI®5 package is internally connected to the cathode terminal. It must be soldered to a cathode-biased copper pour; using it as a floating thermal sink or connecting it to ground will cause short-circuit failure.

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

Unlike conventional Schottkys, the TrenchSBR structure exhibits no minority-carrier storage, resulting in negligible reverse recovery charge (Qrr ≈ 0). This eliminates switching spikes and EMI associated with Qrr in hard-switched topologies-confirmed by zero-recovery waveforms in Diodes' application note AN-7002.

Can it replace a 20A TO-220 Schottky in existing designs?

Yes-but only with PCB layout revision: the POWERDI®5 requires thermal pad soldering to a dedicated cathode copper pour, unlike TO-220's insulated tab. Electrical substitution is valid (same VRRM, IO, VF), but thermal performance improves only if the new layout implements ≥250 mm² of 2-oz copper connected to the pad.
