Product details

Overview

IDM05G120C5XTMA1 from Infineon Technologies is a 5th Generation CoolSiC™ 1200 V, 5 A silicon carbide Schottky diode in PG-TO252-2 package, featuring zero reverse recovery charge, 24 nC total capacitive charge at 800 V/150°C, and 175°C maximum junction temperature - deployed in high-efficiency solar inverters and PFC stages.

For engineers reviewing the IDM05G120C5XTMA1 datasheet, IDM05G120C5XTMA1 pinout, IDM05G120C5XTMA1 application, or IDM05G120C5XTMA1 equivalent, key selection criteria include its 1200 V repetitive peak reverse voltage, temperature-independent switching, tight VF distribution (1.50–1.80 V @ 5 A/25°C), and dv/dt ruggedness of 150 V/ns.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-voltage DC-link rectification, eliminating reverse recovery losses and enabling >100 kHz switching in PFC and inverter stages. Its unipolar conduction mechanism ensures no minority-carrier storage, resulting in zero Qrr and minimal EMI generation.

Thermal performance is optimized via low Rth(j-c) of 0.8–1.04 K/W and operation up to 175°C junction temperature, supporting compact heatsink designs. The device sustains 59 A non-repetitive surge current (10 ms, TC=25°C) and exhibits stable capacitance (17 pF @ 800 V, 1 MHz) across temperature and bias.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1200 V - supports DC-link voltages up to 1000 V bus in 3-phase inverters with 20% safety margin
I_F	5 A continuous @ T_C=164°C - enables high-power density in thermally constrained SMD layouts
Q_C	24 nC @ V_R=800 V, T_j=150°C - determines turn-off energy loss in hard-switched converters
V_F	1.50–1.80 V @ I_F=5 A, T_j=25°C - delivers lower conduction loss than Si FRD equivalents at same current
R_th(j-c)	0.8–1.04 K/W - allows direct thermal coupling to PCB copper for passive cooling without external heatsink
dv/dt	150 V/ns - withstands rapid voltage transients in motor drive and inverter bridge legs
T_j,max	175°C - extends lifetime and reliability under sustained overload or ambient temperature stress

Pinout & Package

Package: PG-TO252-2 (DPAK), surface-mount, thermally enhanced with exposed cathode pad on backside.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SiC Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D05120E (Wolfspeed)	Same 1200 V/5 A rating; higher typical V_F (1.75 V @ 5 A/25°C); R_th(j-c) = 1.2 K/W	Limited surge rating (45 A, 10 ms); less robust dv/dt (100 V/ns)	Preferred where cost sensitivity outweighs thermal margin; verify layout for higher R_th
STPSC5H12D (STMicroelectronics)	1200 V/5 A; tighter V_F tolerance (±0.05 V); lower Q_C (21 nC); R_th(j-c) = 0.95 K/W	Lower surge rating (42 A, 10 ms); JEDEC qualification not explicitly stated for industrial UPS	Better for precision PFC where low Q_C dominates; confirm qualification scope for mission-critical UPS

Compared with C3D05120E and STPSC5H12D, IDM05G120C5XTMA1 offers superior surge robustness (59 A), guaranteed dv/dt (150 V/ns), and JEDEC-qualified reliability - making it optimal for high-stress industrial inverters and grid-tied UPS where transient immunity and long-term stability are critical.

FAQ

What is the maximum allowable case temperature for continuous operation?

The IDM05G120C5XTMA1 supports continuous forward current of 5 A at case temperature (T_C) up to 164°C, as specified in the datasheet's maximum ratings table. This rating assumes D=1 duty cycle and uses the maximum junction-to-case thermal resistance (R_th(j-c),max = 1.04 K/W). Exceeding this T_C requires derating per the P_tot vs. T_C curve in Figure 1.

Does this diode require a gate resistor or driver circuit?

No - the IDM05G120C5XTMA1 is a passive Schottky diode with no gate terminal or control input. It operates solely based on anode-cathode voltage polarity and does not require external driving circuitry, unlike MOSFETs or IGBTs. Its switching behavior is fully intrinsic and governed by SiC material properties.

Can IDM05G120C5XTMA1 be paralleled with identical units?

Yes - its tight forward voltage distribution (±0.15 V at 5 A/25°C) and positive temperature coefficient of V_F enable stable current sharing when paralleled. Layout symmetry (equal trace inductance/resistance) and shared thermal plane are required; no external ballasting resistors are needed per the datasheet recommendations.

Is the PG-TO252-2 package lead-free and RoHS compliant?

Yes - the IDM05G120C5XTMA1 uses Pb-free lead plating and is fully RoHS compliant, as confirmed in the "Features" section of the final datasheet Rev. 2.1. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for reflow soldering up to 260°C peak temperature.
