Product details

Overview

IDW30E60FKSA1 from Infineon Technologies is a 600 V, 30 A fast-switching emitter-controlled diode (ECD) optimized for high-efficiency PFC stages in industrial power supplies and motor drives. It delivers 1.65 V forward voltage at 30 A and 25 °C, 143 W power dissipation, 175 °C maximum junction temperature, and soft reverse recovery with 1.20 µC Q_rr at 25 °C - enabling stable operation up to 30 kHz switching frequency.

For engineers reviewing the IDW30E60FKSA1 datasheet, IDW30E60FKSA1 pinout, IDW30E60FKSA1 application, or IDW30E60FKSA1 equivalent, key selection criteria include reverse recovery charge (Q_rr), softness factor (di_rr/dt), thermal resistance (R_thJC = 1.05 K/W), and paralleling capability - all critical for high-reliability, high-frequency PFC designs.

Technical Context

The IDW30E60FKSA1 implements Infineon's proprietary emitter-controlled diode technology to suppress minority carrier injection during turn-off, resulting in low Q_rr, reduced di_rr/dt magnitude (–108 A/µs), and minimal voltage overshoot. Its internal emitter inductance is specified at 13.0 nH, measured 5 mm from the case.

This diode operates with defined dynamic behavior across temperature: t_rr increases from 143 ns at 25 °C to 255 ns at 175 °C under identical test conditions (V_R = 400 V, I_F = 30 A, di_F/dt = 1000 A/µs), while Q_rr rises from 1.20 µC to 2.80 µC - enabling predictable thermal and EMI design margins.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports DC-link voltages up to 400 V nominal with 50 % safety margin in boost PFC topologies.
I_F(AV)	30 A at T_C = 115 °C - continuous conduction mode (CCM) PFC output current rating with standard heatsink mounting.
V_F	1.65 V at I_F = 30 A, T_J = 25 °C - enables <1.5 W conduction loss per device at rated current, reducing thermal load.
Q_rr	1.20 µC at T_J = 25 °C - low stored charge minimizes switching losses and EMI generation in hard-switched PFC stages.
t_rr	143 ns at T_J = 25 °C - fast, soft recovery reduces voltage spikes and snubber requirements in 30 kHz PFC designs.
R_thJC	1.05 K/W - allows direct thermal path to heatsink; enables 143 W dissipation at ΔT = 150 K (T_J = 175 °C, T_C = 25 °C).
T_J(max)	175 °C - supports operation in high-ambient industrial environments without derating below full current.

Pinout & Package

Supplied in PG-TO247-3 package with isolated mounting flange. Pin 1 is not connected; Pin 2 is cathode; Pin 3 is anode. The package supports high-current, low-inductance PCB layouts and mechanical robustness in industrial power modules.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	No connection (NC)	Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or latch-up risk.
Pin 2	Cathode	Main current return path; bonded directly to die cathode metallization; requires low-inductance trace routing.
Pin 3	Anode	Main current input terminal; connects to boost inductor node; designed for high di_F/dt handling.

Key Features

Feature	Design Value
Emitter-controlled architecture	Eliminates minority carrier tail current, enabling soft, low-Q_rr recovery without external snubbers.
Soft switching behavior	di_rr/dt = –108 A/µs (typ.) - limits voltage overshoot and radiated EMI in high-di/dt PFC circuits.
Easy paralleling capability	Matched dynamic characteristics and low thermal resistance enable stable current sharing without ballasting resistors.
Pb-free, RoHS-compliant plating	Meets JEDEC J-STD-609 Category 1A - suitable for lead-free reflow and wave soldering (260 °C, 10 s).

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06D	600 V, 30 A, 1.75 V V_F, 2.1 µC Q_rr at 25 °C, TO-247AC package	Higher conduction and switching losses; less soft recovery (di_rr/dt ≈ –150 A/µs)	Acceptable where cost sensitivity outweighs efficiency targets; requires larger heatsink and snubber.

FAQ

What is the maximum allowable case temperature for continuous 30 A operation?

The IDW30E60FKSA1 supports 30 A average forward current at case temperature (T_C) up to 115 °C, as specified in the Absolute Maximum Ratings table. Operation above this temperature requires linear current derating per Figure 2 in the datasheet, reaching zero current at 175 °C case temperature.

Is Pin 1 internally connected or electrically isolated?

Pin 1 is explicitly designated as "not connected" (NC) in the official package pin definition and must remain unconnected in PCB layout. It is electrically isolated from both anode and cathode terminals and serves no functional role - connecting it risks introducing parasitic paths or compromising thermal performance.

How does the diode's soft recovery affect EMI in a 30 kHz PFC stage?

The IDW30E60FKSA1's soft recovery - characterized by di_rr/dt = –108 A/µs and low Q_rr - reduces high-frequency spectral content in the switching node, lowering conducted and radiated EMI. This allows smaller EMI filters and simplifies compliance testing for EN 55011 Class A in industrial power supplies.

Can multiple IDW30E60FKSA1 diodes be paralleled without external balancing components?

Yes - the ECD technology ensures matched dynamic characteristics and low thermal resistance (R_thJC = 1.05 K/W), enabling stable current sharing between paralleled units. Layout symmetry (equal trace inductance/resistance) and shared heatsink contact are required, but no ballasting resistors or active current-sharing circuits are needed.
