概述

Description

MBRS320 is a Schottky barrier rectifier diode in the MBRS family, used for fast, efficient rectification in switching power supplies and DC‑DC converters. The “320” usually indicates a high reverse rating (around 320 V), with variants rated for about 3 A average forward current. Key benefits are a low forward voltage drop (roughly ~0.4–0.5 V at 3 A), very fast switching, and low leakage at moderate temperatures, which improves efficiency at high frequencies. It is available in surface‑mount packages (e.g., SMB/DO‑214AB and other SMD variants). Common applications include input/output rectification, freewheeling in buck/boost converters, and general polarity protection in power electronics. Always consult the specific variant’s datasheet (e.g., MBRS320T3G, MBRS320LT1G) for exact VRRM, IF(AV), VF, and packaging, as ratings vary by package and revision.

Features

MBRS320 features (Schottky barrier rectifier)
- IF(AV): 3 A average rectified current
- VRRM: 320 V reverse voltage
- Low forward voltage drop: around 0.5–0.6 V at 3 A
- Very fast switching: no reverse-recovery delay (Schottky)
- High surge current capability for transients (I FSM ~50 A)
- Package: surface-mount (SMB/DO-214AB or compatible, rugged molded plastic)
- RoHS compliant
- Temperature range: typically -55°C to +125°C (junction)

Package

I need the exact manufacturer/variant. MBRS320 package can vary by maker—common types are DO-214AA (SMA) or DO-214AB (SMB). Provide the full part number (e.g., MBRS320T3G) or a datasheet link and I’ll give the exact package.

Pinout

- Pin count: 2 pins (Anode and Cathode).
- Function: MBRS320 is a Schottky barrier rectifier diode. It provides low forward voltage drop and fast, low‑recovery rectification for power-supply rectification, freewheeling, and reverse‑polarity protection (use the cathode and anode pins accordingly).

Manufacturer

- Manufacturer: Vishay Intertechnology (Vishay).
- Company type: A global electronics components manufacturer that designs and produces semiconductors and passive components (e.g., Schottky diodes, rectifiers, resistors, capacitors).

Application

MBRS320 is a Schottky barrier rectifier (≈3 A). Typical applications:
- Rectification in high-frequency switch-mode power supplies and DC-DC converters
- Freewheeling/flyback diodes in buck/boost/flyback topologies
- Input/output rectification in AC–DC adapters and battery chargers
- Reverse-polarity protection and diode-ORing for redundant rails
- Automotive/industrial power electronics needing low forward drop and fast switching
