Infineon Technologies IDH08S60CAKSA1

Overview

IDH08S60CAKSA1 from Infineon Technologies is a 2nd-generation thinQ!™ silicon carbide (SiC) Schottky diode rated for 600 V DC blocking voltage, 8 A continuous forward current, and 19 nC total capacitive charge. It operates with zero reverse recovery, no forward recovery, and stable switching behavior across -55 °C to 175 °C junction temperature - deployed in CCM PFC stages and motor drive inverters where high-frequency efficiency and thermal robustness are critical.

For engineers reviewing the IDH08S60CAKSA1 datasheet, IDH08S60CAKSA1 pinout, IDH08S60CAKSA1 application, or IDH08S60CAKSA1 equivalent, key selection criteria include its 2 K/W junction-to-case thermal resistance, 50 V/ns dv/dt ruggedness, absence of minority-carrier recovery, and PG-TO220-2 package compatibility with standard heatsink mounting.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-efficiency AC/DC and DC/AC conversion stages. Its unipolar conduction eliminates reverse recovery losses and enables operation at >100 kHz without thermal runaway, supported by a 310 pF capacitance at 1 V reverse bias and <10 ns capacitive time constant.

The device features a thermally optimized PG-TO220-2 package with direct die-to-case thermal path, enabling 75 W power dissipation at 25 °C case temperature. Its reverse leakage remains below 1000 µA at 600 V and 150 °C, and surge capability reaches 59 A (10 ms sine half-wave) with 17 A²s i²t rating.

FAQ

What is the maximum allowable case temperature for continuous 8 A operation?

The datasheet specifies I_F = 8 A is rated at T_C ≤ 140 °C. At T_C = 140 °C, junction temperature reaches 175 °C (T_j = T_C + P_tot × R_thJC ≈ 140 + 48 × 2 = 176 °C), matching the absolute maximum rating. Operation above 140 °C case requires derating.

Does IDH08S60CAKSA1 require a gate resistor or snubber network?

No - as a Schottky diode, it has no gate terminal and does not require gate drive components. However, a small RC snubber (e.g., 100 Ω + 100 pF) across the diode is recommended in hard-switched IGBT bridges to damp ringing caused by stray inductance interacting with its 50 pF capacitance at 600 V.

Can IDH08S60CAKSA1 be paralleled for higher current handling?

Yes - its positive temperature coefficient of forward voltage ensures natural current sharing. Parallel operation requires matched layout (equal trace inductance/resistance), shared heatsink mounting, and thermal coupling. Derate total current by 15% for two devices and 25% for three or more to account for thermal imbalance.

Is the PG-TO220-2 package electrically insulated?

Yes - the PG-TO220-2 package uses reinforced plastic insulation between the metal tab (cathode) and mounting surface. The tab is rated for 2500 V_AC isolation per UL 60747-17, enabling direct heatsink mounting without insulating washers in most industrial applications.
