Product details

Overview

IDH09SG60CXKSA2 from Infineon Technologies is a 3rd-generation silicon carbide (SiC) Schottky diode rated for 600 V repetitive peak reverse voltage and 9 A continuous forward current at T_C < 130 °C, featuring zero reverse recovery charge, <10 ns switching time, and 15 nC total capacitive charge. It serves as a high-efficiency freewheeling or boost diode in CCM PFC stages of industrial SMPS.

For engineers reviewing the IDH09SG60CXKSA2 datasheet, IDH09SG60CXKSA2 pinout, IDH09SG60CXKSA2 application, or IDH09SG60CXKSA2 equivalent, key selection criteria include its temperature-independent switching behavior, 1.3 K/W junction-to-case thermal resistance, surge capability up to 49 A (t_p=10 ms), and RoHS-compliant Pb-free lead plating.

Technical Context

This SiC Schottky diode eliminates minority-carrier injection, resulting in no reverse recovery time (t_rr) and no forward recovery voltage overshoot. Its capacitive switching mechanism yields a fixed t_c < 10 ns independent of junction temperature, load current, or di/dt - unlike silicon PN diodes.

Thermal performance is defined by R_thJC = 1.3 K/W and operation across –55 °C to +175 °C junction temperature. The device sustains 400 A non-repetitive peak forward current at t_p = 10 µs and delivers 12 A²s ∫i²dt rating at T_C = 25 °C for short-circuit robustness.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports 400 V DC-link designs with 50 % voltage margin for transient clamping in PFC and solar inverters
I_F (cont)	9 A @ T_C < 130 °C - enables compact heatsink design in 1–2 kW power supplies without forced air
V_F	1.8–2.1 V @ 9 A, 25 °C - low conduction loss improves efficiency over Si diodes by ~0.5 % in CCM PFC
Q_C	15 nC - reduces turn-off losses in hard-switched topologies; enables higher-frequency operation than Si alternatives
R_thJC	1.3 K/W - allows direct mounting to heatsink with minimal thermal interface resistance for reliable 175 °C operation
t_c	<10 ns - defines capacitive displacement current decay; eliminates reverse recovery-related EMI and snubber losses
I_R	0.7 µA @ 600 V, 25 °C - ultra-low leakage preserves efficiency in high-impedance gate drive or sensing circuits

Pinout & Package

PG-TO220-2 package with isolated metal tab; case (Pin 1) is cathode, lead (Pin 2) is anode. Mounting torque: 60 N·cm for M3/M3.5 screws. Soldering allowed only on leads ≥1.6 mm from case for 10 s at 260 °C.

Pin/Terminal	Circuit Role	Design Meaning
Case (Pin 1)	Cathode	Electrically connected to internal die cathode; serves as primary thermal path and must be electrically isolated from heatsink unless system ground reference permits
Lead (Pin 2)	Anode	Single wire-bonded anode terminal; designed for low-inductance PCB layout with short, wide copper pour to minimize switching loop area

Key Features

Feature	Design Value
No reverse recovery	Eliminates t_rr-related switching losses and EMI, enabling clean hard-switched operation without snubbers
Temperature-stable Q_C and V_F	Capacitive charge remains constant across –55 °C to +175 °C, ensuring predictable timing in thermal cycling environments
High dv/dt ruggedness	50 V/ns rating prevents false triggering in high-di/dt motor drive or inverter half-bridges
JEDEC-qualified reliability	Qualified per J-STD-20 and JESD22 for automotive and industrial applications requiring long-term parametric stability
Low figure-of-merit Q_C/I_F	1.67 nC/A ratio confirms superior high-frequency efficiency vs. competing SiC diodes in same voltage class

Applications

Use Value: Prevents shoot-through risk in high-speed PWM (20 kHz) drives due to absence of minority carrier storage delay.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D09060A (Wolfspeed)	Same 600 V/9 A rating; 1.55 V V_F @ 9 A, 25 °C; R_thJC = 1.5 K/W; TO-220-2 package	Slightly higher V_F increases conduction loss by ~0.15 W at full load; lower thermal conductivity requires larger heatsink footprint	Prefer when legacy Wolfspeed qualification is mandated; verify layout clearance for higher V_F-induced thermal gradient
STPSC9H06D (STMicroelectronics)	600 V/9 A; 1.7 V V_F @ 9 A, 25 °C; R_thJC = 1.4 K/W; TO-220AC package with insulated tab	Lower V_F improves light-load efficiency; insulated tab simplifies mechanical mounting but adds 0.2 K/W thermal penalty	Select for cost-sensitive industrial drives where 0.1 V V_F reduction offsets insulation cost premium

Compared with C3D09060A and STPSC9H06D, IDH09SG60CXKSA2 offers the lowest combined Q_C/I_F ratio (1.67) and tightest V_F distribution (±0.15 V), making it optimal for high-frequency, thermally constrained PFC designs demanding consistent timing and minimal EMI.

FAQ

Is IDH09SG60CXKSA2 suitable for synchronous rectification in LLC resonant converters?

No - this is a unidirectional Schottky diode with cathode-connected case; it lacks the gate control required for synchronous rectification. It functions as a passive freewheeling or boost diode only. For synchronous rectification, discrete MOSFETs or integrated SR controllers must be used instead.

What is the maximum allowable case temperature during continuous operation?

The absolute maximum case temperature is 130 °C for 9 A continuous forward current. Exceeding this derates I_F linearly to 0 A at 175 °C junction temperature. Thermal design must maintain T_C ≤ 130 °C using the specified 1.3 K/W R_thJC and appropriate heatsink interface.

Does IDH09SG60CXKSA2 require a gate resistor or snubber network?

No - as a majority-carrier SiC Schottky diode, it has no gate and exhibits no reverse recovery. Snubbers are unnecessary unless parasitic oscillation occurs due to layout inductance; in such cases, a small RC dampener (<10 Ω + 100 pF) across anode–cathode may suppress ringing.

Can IDH09SG60CXKSA2 replace silicon fast recovery diodes in existing designs?

Yes - with layout review: its lower V_F reduces conduction loss, but its faster switching demands shorter, lower-inductance traces to avoid voltage overshoot. Also verify that the existing heatsink accommodates the 1.3 K/W R_thJC and that mounting torque (60 N·cm) matches screw specification.
