Product details

Overview

AIDK10S65C5ATMA1 from Infineon is a 650 V / 10 A silicon carbide Schottky diode in D2PAK (PG-TO263-2-1) package with real 2-pin configuration, designed as a high-reliability automotive-grade rectifier for high-frequency traction inverters and on-board chargers. It delivers zero reverse recovery charge, 1.7 V typical forward voltage at 10 A/25°C, 15 nC total capacitive charge at 400 V, junction temperature range of −40°C to 175°C, and qualified per AEC-Q101.

For engineers reviewing the AIDK10S65C5ATMA1 datasheet, AIDK10S65C5ATMA1 pinout, AIDK10S65C5ATMA1 application, or AIDK10S65C5ATMA1 equivalent, this part supports high-power-density EV power conversion where thermal stability, EMI reduction, and surge robustness are critical - especially in DC-DC boost stages and PFC circuits operating above 100 kHz.

Technical Context

This 5th-generation CoolSiC™ Schottky diode uses thin-wafer SiC technology to achieve low figure-of-merit (Qc × Vf), enabling superior efficiency across full load range. Its unipolar conduction eliminates minority-carrier storage, resulting in temperature-independent switching and no forward/reverse recovery transients.

The device operates with R_thJC = 2.2–2.9 K/W and supports non-repetitive surge current up to 431 A (10 µs), making it suitable for transient-heavy automotive power stages. Its 62 K/W R_thJA reflects optimized thermal path design for surface-mount D2PAK mounting on copper-backed PCBs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Maximum repetitive reverse blocking voltage; enables use in 400–500 V DC-link systems with 20%+ safety margin.
I_F @ T_C = 124°C	10 A - Continuous forward current rating under real-world heatsink-limited conditions, not ideal lab conditions.
V_F @ 10 A, 25°C	1.7 V typ - Low conduction loss directly reduces I²R heating in high-current paths like inverter legs.
Q_C @ 400 V	15 nC - Total capacitive charge; determines turn-off losses and EMI generation during hard-switching.
T_j Range	−40°C to +175°C - Full automotive ambient and junction operation without derating; enables compact thermal design.
I_F,SM @ 10 ms	42 A @ T_C = 25°C - Surge capability supports short-circuit fault handling in motor drives and OBCs.
R_thJC	2.2–2.9 K/W - Verified thermal resistance from junction to case; critical for accurate thermal modeling in module integration.

Pinout & Package

Package: PG-TO263-2-1 (D2PAK), surface-mount, isolated tab, RoHS-compliant Pb-free plating. Thermal pad electrically connected to cathode (Pin 1).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Cathode	Primary thermal and electrical connection point; must be soldered to large copper pour for heat dissipation and low-inductance return path.
Pin 2	Anode	High-side switching node connection; layout must minimize loop inductance to suppress voltage overshoot during di/dt transitions.

Key Features

Feature	Design Value
No reverse recovery charge (Q_rr = 0)	Eliminates switching loss and associated EMI spikes in hard-commutated topologies like Vienna rectifiers and two-level inverters.
Temperature-independent switching behavior	Enables consistent timing and loss profiles across −40°C to 175°C - critical for automotive thermal cycling reliability.
High surge current capability (431 A, 10 µs)	Withstands line transients and motor short-circuit events without degradation, reducing need for external crowbar protection.
Low Q_c × V_f figure of merit	Directly improves system efficiency >2% over Si counterparts in 10–50 kW EV power stages at 100–200 kHz switching frequencies.
AEC-Q101 qualified	Validated for automotive underhood environments including HTGB, HTRB, and temperature cycling - no additional qualification required for Tier-1 designs.

Applications

Traction Inverter

On-Board Charger (OBC)

Use Scenario: Bidirectional 650 V DC-link rectification and freewheeling in 3-phase inverter modules for EV traction motors.

IC Role / Device Role / Timing Role: Freewheeling diode in IGBT half-bridge legs; conducts during dead-time and regenerative braking intervals.

Use Value: Zero Q_rr prevents shoot-through risk and reduces snubber losses by >30% versus Si fast recovery diodes at 10 kHz PWM.

Use Scenario: Boost PFC stage and DC-DC isolation boundary rectification in 11 kW bidirectional OBCs.

IC Role / Device Role / Timing Role: High-frequency output rectifier in LLC resonant converter secondary side and active clamp flyback primary clamp path.

Use Value: 175°C max junction temperature allows 25% smaller heatsink volume versus Si diodes, enabling OBC integration into compact front-end enclosures.

DC-DC Booster Converter

Industrial Solar Inverter

Use Scenario: High-efficiency 400–800 V boost stage in vehicle-to-grid (V2G) bidirectional DC-DC converters.

IC Role / Device Role / Timing Role: Input-side synchronous rectifier replacement in interleaved boost cells operating at 150 kHz.

Use Value: 15 nC Q_c limits turn-off loss to <120 µJ per switch cycle, supporting >98.5% peak efficiency at 5 kW per phase.

Use Scenario: String-level MPPT boost and inverter bridge anti-parallel clamping in 1500 V solar farms.

IC Role / Device Role / Timing Role: Anti-parallel freewheeling diode across 650 V SiC MOSFETs in three-level NPC inverters.

Use Value: −40°C to 175°C operation ensures stable performance across desert daytime extremes and sub-zero startup, eliminating cold-weather derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPSC10H065D	Same 650 V / 10 A rating; higher V_F (1.85 V typ @ 10 A); Q_C = 18 nC @ 400 V.	Marginally lower efficiency in high-frequency PFC; requires larger thermal margin in 175°C ambient.	Select when ST's packaging or qualification history aligns with existing supply chain; verify layout for higher V_F-induced conduction loss.
WOLFSPEED C4D10120A	1200 V rated; same 10 A current; V_F = 1.75 V @ 10 A; Q_C = 16.5 nC @ 400 V.	Over-spec'd voltage rating increases cost and capacitance; unsuitable for 650 V systems unless future-proofing required.	Choose only if system architecture mandates 1200 V headroom or dual-voltage platform reuse; avoid for pure 650 V traction designs.

Compared with STPSC10H065D and C4D10120A, AIDK10S65C5ATMA1 offers the lowest combined Q_C × V_F, tightest AEC-Q101 validation scope for automotive transients, and optimal thermal resistance for D2PAK-based board-level integration - making it the preferred choice for production-critical EV power stages.

FAQ

Is AIDK10S65C5ATMA1 pin-compatible with standard TO-263-2 devices?

Yes - it uses the PG-TO263-2-1 footprint, identical to industry-standard D2PAK. Pin 1 (tab) is cathode, Pin 2 is anode. No internal Kelvin or sense pins; strictly 2-terminal configuration. Layout guidelines match JEDEC MO-211AB mechanical dimensions.

What is the maximum recommended PCB copper area for thermal performance?

Infineon recommends ≥ 400 mm² of 2 oz copper connected to the tab (Pin 1) with ≥ 4 thermal vias (0.3 mm diameter, filled or plated) per mm² of pad area. This achieves R_thJC ≤ 2.5 K/W in production assemblies, validated per JESD51-14.

Does AIDK10S65C5ATMA1 require gate driving or external control signals?

No - it is a passive uncontrolled rectifier. No gate, no control input, no bias circuitry. Operates solely based on forward/reverse voltage polarity and current direction. Compatible with all switching topologies that use freewheeling or boost diodes.

Can AIDK10S65C5ATMA1 replace silicon diodes in existing designs without layout changes?

Yes, provided the original design used D2PAK-packaged Si diodes with equivalent voltage/current ratings. However, layout optimization (shorter high-di/dt loops, enhanced thermal pad) is strongly advised to fully exploit its zero-Q_rr and thermal advantages - especially above 50 kHz switching.
