Infineon Technologies IDDD16G65C6XTMA1

Overview

IDDD16G65C6XTMA1 from Infineon is a 650 V, 16 A silicon carbide Schottky diode in PG-HDSOP-10-1 package, featuring 1.25 V forward voltage at 16 A and 21.5 nC capacitive charge at 400 V. It delivers high dv/dt ruggedness (150 V/ns) and low figure of merit (Qc × VF), enabling high-efficiency PFC stages in industrial SMPS.

For engineers reviewing the IDDD16G65C6XTMA1 datasheet, IDDD16G65C6XTMA1 pinout, IDDD16G65C6XTMA1 application, or IDDD16G65C6XTMA1 equivalent, key selection criteria include reverse recovery performance, thermal resistance (RthJC = 0.6 K/W), surge current capability (IF,RM = 70 A), junction temperature range (–55 to 175 °C), and SMD-compatible PG-HDSOP-10-1 footprint with isolated anode/cathode terminals.

Technical Context

This SiC Schottky diode operates with zero reverse recovery charge and exhibits temperature-stable VF characteristics due to its wide-bandgap material and novel Schottky metal system. Its low Qc (21.5 nC at VR = 400 V) and low EC (4.3 µJ at VR = 400 V) directly reduce switching losses in hard-switched topologies.

The device is rated for repetitive peak reverse voltage of 650 V and supports continuous forward current up to 16 A at TC ≤ 145 °C. Its 150 V/ns dv/dt ruggedness ensures robust operation in fast-switching converters without snubbers.

FAQ

What is the maximum allowable case temperature for continuous operation?

The IDDD16G65C6XTMA1 supports continuous forward current of 16 A at case temperature (TC) ≤ 145 °C with duty cycle D = 1. At TC = 125 °C, it can handle up to 23 A; at TC = 25 °C, the limit rises to 43 A. Derating curves are provided in Figure 2 of the datasheet.

Does this diode require a gate resistor or snubber circuit?

No. The IDDD16G65C6XTMA1 has no gate terminal and exhibits zero reverse recovery charge. Its 150 V/ns dv/dt ruggedness eliminates the need for snubbers in typical 650 V hard-switched applications, including those using GaN or SiC MOSFETs.

Can IDDD16G65C6XTMA1 replace silicon diodes in existing designs?

Yes, but layout and thermal design must be updated. Its lower VF reduces conduction loss, but its faster switching demands careful PCB layout to minimize parasitic inductance. Also, verify that existing gate drivers and controllers accommodate reduced dead-time requirements.

Is the PG-HDSOP-10-1 package lead-free and RoHS-compliant?

Yes. The IDDD16G65C6XTMA1 uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Reflow soldering is permitted up to 260 °C peak temperature per JEDEC J-STD-020.
