Product details

Overview

AIDW30S65C5XKSA1 from Infineon is a 650 V, 30 A silicon carbide Schottky diode in TO-247-3 package, designed as a unidirectional high-voltage freewheeling/anti-parallel diode for traction inverters and DC-DC converters. It delivers zero reverse recovery charge (Q_rr = 0), 1.7 V typical forward voltage at 30 A/25°C, and operates up to 175°C junction temperature.

For engineers reviewing the AIDW30S65C5XKSA1 datasheet, AIDW30S65C5XKSA1 pinout, AIDW30S65C5XKSA1 application, or AIDW30S65C5XKSA1 equivalent, key selection criteria include its 43 nC capacitive charge at 400 V, 100 V/ns dv/dt ruggedness, 1.0 K/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive power modules.

Technical Context

This 5th-generation CoolSiC™ diode uses thin-wafer SiC epitaxy and optimized Schottky barrier design to eliminate minority-carrier storage effects. Its static and dynamic behavior-VF, Q_C, C_iss, and E_C-is stable across -40°C to 175°C, enabling predictable high-frequency switching without thermal runaway risk.

It is engineered for complementary use with Infineon's 650 V IGBTs and CoolMOS™ devices in hard-switched topologies. The device supports sine-halfwave surge currents up to 165 A (10 ms, T_C = 25°C) and withstands 100 V/ns transient voltage slew rates under full blocking conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Maximum repetitive reverse voltage; enables direct use in 400 V DC-link automotive inverters with 1.6× safety margin.
I_F	30 A @ T_C = 121°C - Continuous forward current rating; defines heatsink sizing for sustained conduction in on-board chargers.
V_F	1.7 V typ. @ 30 A, 25°C - Low forward drop reduces conduction loss by ~40% vs. silicon fast recovery diodes at same current.
Q_C	43 nC @ V_R = 400 V - Total capacitive charge; determines turn-on switching loss in synchronous rectification and snubberless designs.
R_thJC	1.0 K/W - Junction-to-case thermal resistance; enables direct mounting to cold plates with minimal thermal interface resistance penalty.
dv/dt	100 V/ns - Minimum guaranteed voltage transient immunity; ensures robust operation during IGBT commutation in noisy traction systems.
T_j,max	175°C - Maximum junction temperature; allows derating-free operation in engine bay environments with active cooling.

Pinout & Package

Package: TO-247-3 (PG-TO247-3-41), isolated case, RoHS-compliant lead plating. Pin 2 is cathode (case-connected), Pin 3 is anode. Mounting torque: 70 N·cm for M3/M4 screws.

Pin/Terminal	Circuit Role	Design Meaning
Pin 2 (Case)	Cathode	Electrically tied to cathode metallization; provides low-inductance, low-thermal-resistance heat path to heatsink.
Pin 3	Anode	Main current-carrying terminal for forward conduction; routed to DC-link or switching node in half-bridge leg.
Pin 1 (Not connected)	NC / Thermal relief	No internal connection; used for mechanical stability and optional auxiliary thermal pad attachment.

Key Features

Feature	Design Value
Zero reverse recovery (Q_rr = 0)	Eliminates switching tail current and associated losses, enabling >100 kHz operation without snubbers in PFC stages.
Temperature-stable VF and Q_C	Forward voltage drift < ±5% from 25°C to 150°C; ensures consistent efficiency across full automotive ambient range.
AEC-Q101 qualified	Validated for automotive powertrain applications including traction inverters, meeting stress test requirements for HTGB, HTRB, and ESD.
High dv/dt ruggedness (100 V/ns)	Withstands rapid voltage transients during IGBT turn-off without false triggering or avalanche breakdown.
Low figure-of-merit (Q_C × V_F)	Optimized trade-off between switching and conduction loss; improves system efficiency over Si diodes by 0.5–1.2% in 650 V DC-DC converters.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPSC30H065D	Same 650 V/30 A rating; higher V_F (1.85 V typ.); Q_C = 48 nC; R_thJC = 1.2 K/W.	Suitable for industrial UPS but lacks AEC-Q101 validation; not qualified for automotive traction duty cycles.	Select when cost sensitivity outweighs automotive qualification and thermal performance requirements.
Wolfspeed C4D30065A	Identical V_RRM/I_F; V_F = 1.65 V typ.; Q_C = 40 nC; R_thJC = 0.9 K/W; requires different mounting hardware.	Validated per AEC-Q101 Grade 0; preferred for space-constrained modules where 0.1 K/W thermal advantage matters.	Select for highest efficiency in compact, liquid-cooled traction inverters where thermal interface optimization is critical.

Compared with STPSC30H065D and C4D30065A, AIDW30S65C5XKSA1 offers balanced trade-offs: certified automotive reliability, industry-leading dv/dt ruggedness (100 V/ns), and proven integration with Infineon's IGBT gate drivers-making it optimal for production-grade EV power stacks.

FAQ

Is AIDW30S65C5XKSA1 pin-compatible with previous-generation CoolSiC diodes?

No. AIDW30S65C5XKSA1 uses the TO-247-3 package with cathode-connected case (Pin 2), while earlier G3/G4 variants like AIDW30S65C5 use TO-247-2. The third pin (Pin 1) is NC but affects mechanical mounting and thermal interface design-direct replacement requires PCB and heatsink requalification.

What is the maximum recommended mounting torque for AIDW30S65C5XKSA1?

The datasheet specifies 70 N·cm for M3 and M4 screws. Exceeding this risks ceramic substrate cracking or solder joint fracture. Torque must be applied evenly across all fasteners, and thermal interface material thickness should be controlled to ≤ 0.1 mm to maintain R_thJC ≤ 1.0 K/W.

Does AIDW30S65C5XKSA1 require a negative gate drive or special snubbing?

No. As a Schottky diode, it has no gate and requires no drive circuitry. Its zero Q_rr eliminates need for RC snubbers in most topologies. However, layout parasitics must be minimized-especially cathode loop inductance-to preserve dv/dt ruggedness and avoid voltage overshoot during fast commutation.

Can AIDW30S65C5XKSA1 be used in non-automotive industrial applications?

Yes. While AEC-Q101 qualified, its 175°C T_j,max, 650 V rating, and robust surge capability make it suitable for industrial motor drives, solar string inverters, and UPS systems. Derating guidelines in Infineon's AN2019-05 apply, and lifetime estimation must account for actual thermal cycling profiles.
