Diodes Incorporated G15H150D5

Overview

G15H150D5 from Diodes Incorporated is a Trench Schottky rectifier optimized for high-efficiency power supply applications, featuring 150 V reverse voltage rating, 15 A average forward current at TC = 125°C, and ultra-low forward voltage drop (0.68 V typ. at 15 A, TJ = 125°C). It operates up to 150°C junction temperature and is AEC-Q101 Rev_C qualified for automotive-grade reliability.

For engineers reviewing the G15H150D5 datasheet, G15H150D5 pinout, G15H150D5 application, or G15H150D5 equivalent, key selection criteria include forward voltage optimization at high temperature, soft fast switching behavior, thermal resistance (RthJC = 2°C/W), and PowerDI5 package compatibility with high-density PCB layouts.

Technical Context

This device employs trench-based Schottky architecture to minimize forward conduction loss while maintaining low reverse leakage and soft reverse recovery-critical for reducing EMI and improving efficiency in synchronous rectification and DC-DC converter outputs. Its 905 pF junction capacitance at 4 V DC enables stable high-frequency operation.

The PowerDI5 package provides low thermal resistance (2°C/W junction-to-case) when mounted on a 60 mm × 60 mm × 1.7 mm copper heatsink, supporting continuous 15 A conduction at case temperatures up to 125°C per derating curve. It is halogen- and antimony-free, RoHS-compliant, and rated for -55°C to +150°C operating range.

FAQ

What is the maximum allowable case temperature for continuous 15 A operation?

The G15H150D5 supports 15 A average forward current at TC = 125°C, as specified in the Absolute Ratings table. Operation above this temperature requires derating per Figure 1; at TC = 135°C, maximum I(AV) drops to ~13.5 A. Thermal design must ensure the case temperature remains within limits using the stated RthJC = 2°C/W and appropriate copper area.

Is G15H150D5 pin-compatible with other PowerDI5 Schottky rectifiers?

Yes-G15H150D5 uses the standard PowerDI5 outline (JEDEC MO-295) with identical mechanical dimensions and terminal locations as other PowerDI5 rectifiers like SB15150T and SS15150. However, differences in VF, thermal resistance, and qualification status require functional validation before substitution.

Does G15H150D5 require a heatsink for 15 A operation?

A heatsink is not required in the strictest sense, but the device must be mounted on ≥200 mm² of 2 oz copper to achieve the rated RthJC = 2°C/W. Without adequate copper area, junction temperature will exceed 150°C under full load. The datasheet specifies thermal testing on a 60 mm × 60 mm × 1.7 mm copper heatsink.

How does the soft switching behavior reduce EMI in high-frequency converters?

G15H150D5 exhibits no reverse recovery charge (Qrr ≈ 0) due to its Schottky barrier structure, eliminating the high di/dt current spike and associated ringing seen in PN junction rectifiers. This results in cleaner switching waveforms, reduced common-mode noise, and simplified EMI filter design-especially critical in >500 kHz DC-DC topologies.
