Infineon Technologies IDW30C65D2XKSA1

Overview

IDW30C65D2XKSA1 from Infineon Technologies is an emitter-controlled diode (ECD) with rapid switching, dual-anode/common-cathode configuration, rated for 650 V V_RRM, 30 A total forward current (15 A per leg), 1.6 V forward voltage at 15 A and 25°C, and 175°C maximum junction temperature - optimized for continuous conduction mode (CCM) power factor correction boost stages in industrial AC-DC supplies.

For engineers reviewing the IDW30C65D2XKSA1 datasheet, IDW30C65D2XKSA1 pinout, IDW30C65D2XKSA1 application, or IDW30C65D2XKSA1 equivalent, key selection criteria include reverse recovery charge (Q_rr = 0.12–0.37 µC), soft switching behavior, low di/dt sensitivity, thermal resistance (R_th(j–c) = 1.75 K/W), and TO-247-3 package compatibility with high-power heatsinking.

Technical Context

This emitter-controlled diode integrates two independent fast-recovery diode legs sharing a common cathode terminal, enabling interleaved or parallel boost operation without external current-sharing components. Its ECD architecture delivers stable V_F over temperature and reduced Q_rr dispersion versus conventional silicon diodes.

Switching performance is characterized under controlled inductive-load conditions (VR = 400 V, IF = 15 A, di_F/dt = 200–1000 A/µs), with trr ≤ 51 ns and dirr/dt up to –6400 A/µs. The device supports operation up to 175°C junction temperature and exhibits low internal emitter inductance (L_E = 13 nH).

FAQ

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies a maximum junction temperature of 175°C and provides power dissipation curves showing 43 W at T_C = 100°C. For reliable long-term operation, Infineon recommends limiting case temperature to ≤ 100°C when operating at full 30 A total current, ensuring sufficient thermal margin against transient overload and aging effects.

Can IDW30C65D2XKSA1 be used in parallel with another identical device?

No - IDW30C65D2XKSA1 already integrates two matched diode legs in one package with common cathode; paralleling multiple units introduces thermal imbalance and current-sharing risk due to package-level thermal coupling differences. Instead, use its dual-leg structure for interleaving or redundancy within a single footprint.

Is the backside metal electrically isolated from the leads?

No - the backside metallization is electrically connected to Pin 2 (cathode) and forms part of the cathode terminal. It must be mounted to a heatsink with appropriate electrical isolation (e.g., mica washer or ceramic pad) if the heatsink is not at cathode potential, as confirmed in the PG-TO247-3 mechanical drawing and thermal test conditions.

Does Q_rr increase significantly at elevated temperature?

Yes - Q_rr rises from 0.12 µC at 25°C to 0.37 µC at 175°C under identical test conditions (VR = 400 V, IF = 15 A, di_F/dt = 1000 A/µs), representing a 208% increase. This must be accounted for in worst-case loss calculations and snubber sizing for high-ambient-temperature deployments.
