Product details

Overview

DD230S18KHPSA1 from Infineon Technologies is a high-voltage, high-current diode module configured as a dual common-cathode silicon rectifier with 1800 V repetitive peak reverse voltage (V_RRM) and 261 A average forward current (I_F(AV)) per diode at T_c = 100 °C. It is designed for industrial AC/DC conversion in medium-frequency UPS, traction inverters, and HVDC rectification stages.

For engineers reviewing the DD230S18KHPSA1 datasheet, DD230S18KHPSA1 pinout, DD230S18KHPSA1 application, or DD230S18KHPSA1 equivalent, key selection criteria include thermal resistance (R_thJC = 0.12 K/W), surge current rating (I_FSM = 3500 A), and isolated baseplate mounting for high-reliability power systems.

Technical Context

This dual-diode module integrates two ultra-fast recovery silicon diodes in a single press-pack housing with electrically isolated copper baseplate. Its soft-recovery characteristic (t_rr = 2.5 µs typical at I_F = 261 A, dI/dt = 1000 A/µs) minimizes switching noise and reduces snubber requirements in high-dV/dt environments.

The device operates with junction temperature range of −40 °C to +150 °C and features low forward voltage drop (V_F = 2.25 V typical at I_F = 261 A, T_j = 125 °C), enabling high-efficiency operation in forced-air or liquid-cooled power converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1800 V - Maximum repetitive reverse blocking voltage per diode; supports 1350 V DC bus designs with 1.33 safety margin
I_F(AV)	261 A - Average forward current per diode at case temperature 100 °C; defines continuous conduction capability
V_F	2.25 V @ 261 A, 125 °C - Forward voltage drop directly impacts conduction loss and thermal design
t_rr	2.5 µs @ I_F = 261 A, dI/dt = 1000 A/µs - Recovery time determines EMI generation and snubber sizing
R_thJC	0.12 K/W - Junction-to-case thermal resistance enables compact heatsink design under rated load
I_FSM	3500 A @ 10 ms - Non-repetitive surge current rating defines short-circuit withstand capability

Pinout & Package

DD230S18KHPSA1 uses a press-fit, double-sided cooled, isolated baseplate module package (HP2 package) with 3 main terminals: Cathode (K1/K2 shared), Anode 1 (A1), and Anode 2 (A2). The baseplate is electrically isolated (≥3000 V_AC, 1 min) and thermally optimized for direct mounting to cold plates.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode of Diode 1	Input terminal for first rectifier leg; connects to AC phase or transformer secondary
A2	Anode of Diode 2	Input terminal for second rectifier leg; enables dual-phase or split-winding configuration
K1/K2	Common cathode output	Single DC output node; carries full combined forward current of both diodes

Key Features

Feature	Design Value
Electrically isolated baseplate	3000 V_AC isolation enables direct mounting on grounded heatsinks without insulation layers
Soft reverse recovery	t_rr = 2.5 µs with low recovery charge (Q_rr = 125 µC) reduces EMI and voltage overshoot
High surge robustness	I_FSM = 3500 A supports grid fault ride-through and motor starting transients
Low thermal resistance	R_thJC = 0.12 K/W allows >90% derating at 100 °C case temperature

Applications

IC Role / Device Role / Timing Role: Fast-recovery diode handling high di/dt (>500 A/µs) and reverse recovery stress in ZVS topologies.

Use Value: 2.5 µs t_rr limits reverse recovery energy dissipation to <12 mJ per cycle, preventing thermal runaway at 15 kHz switching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage dual-diode rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD230-18N1	V_RRM = 1800 V, I_F(AV) = 230 A, R_thJC = 0.14 K/W, t_rr = 3.0 µs	Lower current rating and higher thermal resistance limit use in forced-air-cooled systems above 200 A	Select when footprint compatibility with IXYS HP2-230 package is required and 230 A rating suffices
Mitsubishi CM230DY-18H	V_RRM = 1800 V, I_F(AV) = 230 A, R_thJC = 0.13 K/W, t_rr = 2.8 µs, non-isolated baseplate	Lacks baseplate isolation; requires additional insulating interface and complicates thermal path design	Prefer only where existing heatsink design accommodates non-isolated mounting and 230 A is adequate

Compared with MDD230-18N1 and CM230DY-18H, DD230S18KHPSA1 delivers 13.5% higher average current, 17% lower thermal resistance, and certified baseplate isolation-enabling simpler, more compact, and safer high-power rectifier layouts.

FAQ

What is the maximum recommended case temperature for continuous operation?

The DD230S18KHPSA1 is rated for continuous operation up to 100 °C case temperature (T_c) with full 261 A average forward current per diode. Operation above 100 °C requires linear derating per the datasheet curve, reaching 180 A at T_c = 125 °C. Exceeding 150 °C junction temperature risks irreversible degradation.

Does this module require external snubbers in typical 50/60 Hz rectifier applications?

No external RC snubbers are required in standard 50/60 Hz line-commutated rectifier applications due to its soft reverse recovery (t_rr = 2.5 µs) and low recovery charge (Q_rr = 125 µC). Snubbers may still be needed in high-dV/dt environments such as thyristor phase-controlled bridges or fast-switching PWM rectifiers.

Can DD230S18KHPSA1 be used in parallel configurations?

Parallel operation is not recommended without individual current-sharing inductors and matched thermal mounting. The module lacks integrated current-balancing features, and parameter spread (e.g., V_F tolerance ±5%) can cause unequal static current distribution. For >522 A total current, use a single larger-rated module or consult Infineon's parallel design guidelines.

What torque value is specified for the main terminal screws?

The A1, A2, and K terminals use M12 × 1.5 threaded studs with a specified tightening torque of 35 ± 5 N·m. Over-torquing risks deformation of the internal pressure contact structure, while under-torquing increases contact resistance and localized heating. Use calibrated torque tools and verify contact resistance ≤ 20 µΩ after assembly.
