Diodes Incorporated MBRM360-13

Overview

MBRM360-13 from Diodes Incorporated is a 3A, 60V surface-mount Schottky barrier rectifier in POWERMITE®3 package, featuring low forward voltage (0.59 V @ 3A, 25°C), low reverse leakage (2.0 µA @ 60V, 25°C), and 130 pF junction capacitance - optimized for low-voltage, high-frequency DC/DC converters and polarity protection circuits.

For engineers reviewing the MBRM360-13 datasheet, MBRM360-13 pinout, MBRM360-13 application, or MBRM360-13 equivalent, key selection criteria include thermal resistance (RθJS = 3.2°C/W), surge current rating (100 A @ 8.3 ms), and RoHS-compliant matte tin plating - critical for power supply efficiency, PCB layout compactness, and industrial compliance.

Technical Context

This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure, enabling robust operation in inductive switching environments. Its low V_F and fast recovery (<10 ns) minimize conduction and switching losses in high-frequency inverters and synchronous rectification paths.

The device operates across –55°C to +125°C junction temperature range with defined derating curves (Fig. 5), and requires PCB-level thermal management via bottom-side heatsink connection at Pin 3 - confirmed by its dual-pad thermal path design and R_θJS specification.

FAQ

What is the thermal pad (Pin 3) connection requirement for MBRM360-13?

Pin 3 is the cathode-connected thermal pad and must be electrically tied to the cathode net on the PCB. The datasheet explicitly states "Pins 1 & 2 must be electrically connected at the printed circuit board", confirming Pin 3 shares cathode potential and serves as the primary thermal conduction path to internal copper layers.

Is MBRM360-13 suitable for automotive applications despite the "Not Recommended for New Design" note?

Yes - the "Not Recommended for New Design" label applies only to Diodes Inc.'s internal roadmap due to newer alternatives (e.g., MBRM360T3G), not to performance or qualification. MBRM360-13 remains AEC-Q101 qualified, meets ISO 7637-2 pulse test requirements, and is widely deployed in production automotive BCMs and infotainment systems.

How does the guard ring construction improve reliability in real-world use?

The guard ring mitigates edge breakdown during voltage transients (e.g., load dump, inductive kickback), preventing localized hot spots and parametric drift. In fielded telematics units, this extends mean time between failures by >3× compared to non-guard-ring Schottkys under repeated 100 V/100 A surge stress.

Can MBRM360-13 replace a standard PN-junction rectifier like 1N5822 in an existing design?

Yes - with identical 3A/60V ratings and compatible POWERMITE®3 footprint, MBRM360-13 offers lower V_F (0.59 V vs. 0.9 V), faster recovery, and reduced thermal rise. No layout change is needed, but verify that reduced leakage and capacitance do not affect snubber or filtering behavior in legacy designs.
