Product details

Overview

AIDW12S65C5XKSA1 from Infineon is a 650 V / 12 A silicon carbide Schottky diode in TO-247-3 package, designed as a unidirectional high-voltage freewheeling/anti-parallel diode for traction inverters and on-board chargers. It delivers zero reverse recovery charge (Q_c = 18 nC at V_R = 400 V), 175 °C maximum junction temperature, and 76 W power dissipation at T_C = 25 °C.

For engineers reviewing the AIDW12S65C5XKSA1 datasheet, AIDW12S65C5XKSA1 pinout, AIDW12S65C5XKSA1 application, or AIDW12S65C5XKSA1 equivalent, key selection criteria include its SiC-based zero-recovery behavior, automotive-grade AEC-Q101 qualification, thermal resistance R_thJC = 1.5–2.0 K/W, surge current capability (I_F,SM = 71 A at T_C = 25 °C, 10 ms), and low forward voltage (V_F = 1.7 V typ. at 12 A, 25 °C).

Technical Context

This diode leverages Infineon's 5th-generation CoolSiC™ technology with thin-wafer design to achieve low figure-of-merit (Q_c × V_F) and temperature-independent switching. Its static characteristics are production-tested at 25 °C (V_F, I_R), while dynamic parameters like Q_c and C are verified by characterization at 150 °C.

It operates with no minority-carrier storage, eliminating reverse recovery losses and associated EMI. The TO-247-3 package features isolated case (Pin 2) acting as cathode terminal, enabling direct heatsink mounting without electrical isolation pads in high-power motor drive topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - supports DC-link voltages up to 650 V in EV traction inverters and industrial PFC stages
I_F (T_C = 133 °C)	12 A - continuous forward current rating under real-world heatsink conditions
V_F (12 A, 25 °C)	1.7 V typical - reduces conduction loss vs. Si diodes, improving system efficiency at partial load
Q_c (V_R = 400 V)	18 nC - zero reverse recovery enables hard-switched operation at >50 kHz without snubbers
R_thJC	1.5–2.0 K/W - enables direct thermal coupling to heatsink, critical for compact inverter designs
T_j,max	175 °C - allows operation in under-hood automotive environments without derating
I_F,SM (10 ms)	71 A at T_C = 25 °C - withstands short-circuit and startup surge currents in OBC and DCDC 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
STPSC12065D	Same 650 V / 12 A rating; Q_c = 21 nC (V_R = 400 V); R_thJC = 2.3 K/W	Slightly higher conduction loss (V_F = 1.8 V typ.) and lower thermal performance limit peak power density	Preferred where ST ecosystem integration or dual-source strategy is required; verify layout for higher R_thJC
Wolfspeed C4D12065A	Identical V_RRM/I_F; Q_c = 19 nC; V_F = 1.75 V; R_thJC = 1.8 K/W	Same automotive qualification level (AEC-Q101), but different gate drive compatibility assumptions in hybrid modules	Best for designs already using Wolfspeed SiC MOSFETs; requires validation of cathode-tab mounting interface

Compared with STPSC12065D and C4D12065A, AIDW12S65C5XKSA1 offers the lowest R_thJC (1.5 K/W min) and smallest Q_c (18 nC), delivering superior thermal headroom and highest-frequency hard-switching capability in space-constrained traction inverters.

FAQ

Is AIDW12S65C5XKSA1 pin-compatible with standard TO-247-3 silicon diodes?

Yes - it uses the industry-standard PG-TO247-3-41 footprint with identical mechanical dimensions and screw-mounting holes. Pin 1 (anode), Pin 2 (cathode/case), and Pin 3 (anode) align with JEDEC TO-247-3 layouts. However, its isolated metal tab requires verification of heatsink insulation requirements in legacy Si designs.

What is the maximum recommended dv/dt rating for this diode?

The datasheet specifies diode dv/dt ruggedness of 100 V/ns at V_R = 0–480 V. This value is validated under test conditions per JESD22-A114 and reflects immunity to false turn-on during high-speed switching transients in hard-switched inverters.

Does AIDW12S65C5XKSA1 require a gate resistor or external snubber network?

No - as a Schottky diode with no minority carriers, it has no gate and requires no snubber. Its zero reverse recovery eliminates voltage overshoot and ringing during turn-off, simplifying PCB layout and reducing component count in high-frequency converters.

How does the 175 °C junction rating impact system-level thermal design?

The 175 °C T_j,max allows sustained operation at higher case temperatures (e.g., T_C = 133 °C), reducing heatsink size and fan requirements. When combined with R_thJC ≤ 2.0 K/W, it enables >20% smaller thermal solution volume versus 150 °C-rated Si diodes in same power class.
