Product details

Overview

DD800S17HA_B2 from Infineon Technologies is a 1700 V, 800 A dual-diode module designed for high-power inverter applications in industrial motor drives and traction systems. It features 2.50 V max forward voltage at 800 A/125°C, 170 kA²s I²t rating, and 34.0 K/kW junction-to-case thermal resistance per diode.

For engineers reviewing the DD800S17HA_B2 datasheet, DD800S17HA_B2 pinout, DD800S17HA_B2 application, or DD800S17HA_B2 equivalent, key selection criteria include reverse recovery energy (75–155 mJ), stray inductance (20 nH), mounting torque specifications (M6: 4.25–5.75 Nm), and isolation test voltage (4.0 kV RMS).

Technical Context

This module integrates two fast-recovery anti-parallel diodes in a single press-pack-style housing optimized for 3-phase inverter legs. Each diode supports 1600 A repetitive peak forward current with controlled soft recovery characteristics under high di/dt (6300 A/µs) and elevated junction temperature (125°C).

Thermal performance is defined by transient impedance data across four RC network elements (τi = 0.0287–0.988 s), enabling accurate loss and temperature modeling during PWM switching cycles. The module uses basic insulation (IEC 61140 Class 1) with 15.0 mm creepage and 10.0 mm clearance between terminals and heatsink.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	1700 V - Maximum blocking voltage per diode; enables use in 1200 V DC-link industrial inverters with safety margin.
IF (continuous)	800 A - Rated DC forward current per diode; defines steady-state conduction capability at T_vj = 125°C.
I²t (10 ms)	170 kA²s - Short-circuit withstand capability; determines fuse coordination and protection timing in fault conditions.
VF (max, 125°C)	2.50 V - Peak forward voltage at rated current; directly impacts conduction losses and thermal design of heatsink system.
E_rec (125°C)	155 mJ - Reverse recovery energy per pulse; critical for snubber sizing and switching loss calculation in hard-switched topologies.
R_thJC	34.0 K/kW - Junction-to-case thermal resistance per diode; used to calculate ΔT_j-c from measured power dissipation.
L_sCE	20 nH - Stray inductance between collector and emitter terminals; limits dI/dt during turn-off and influences voltage overshoot.

Pinout & Package

DD800S17HA_B2 is housed in a press-fit, isolated baseplate package (similar to PrimePACK™-2 footprint) with three main terminals: P (anode), N (cathode), and C (common cathode connection point). Mounting uses M6 screws on the baseplate and M4/M8 terminal screws per specification.

Pin/Terminal	Circuit Role	Design Meaning
P	Anode of upper diode	Connects to DC-link positive bus; carries full phase current during freewheeling in inverter leg.
N	Cathode of lower diode	Connects to DC-link negative bus; serves as return path for reverse recovery current during commutation.
C	Common cathode node	Internal tie-point linking both diode cathodes; provides low-inductance common reference for dual-diode operation.

Key Features

Feature	Design Value
Soft reverse recovery	IRM = 860 A (125°C), Qr = 265 µC - Minimizes voltage spikes and EMI during forced commutation in motor drives.
High I²t rating	170 kA²s @ 10 ms - Supports robust short-circuit protection without catastrophic failure under overload transients.
Low stray inductance	20 nH - Reduces turn-off overvoltage stress on associated IGBTs and improves switching reliability.
Isolated baseplate	4.0 kV RMS isolation, CTI > 275 - Enables direct mounting on grounded heatsinks without additional insulation layers.
Optimized thermal interface	R_thCH = 8.00 K/kW (λ_grease = 1 W/m·K) - Ensures predictable heat transfer from case to heatsink under standardized thermal paste conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current diode module applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DD800S17K6C_B2	Same manufacturer, identical voltage/current ratings, but higher VF typ. (2.10 V vs. 2.10 V) and slightly lower E_rec (155 mJ vs. 155 mJ); same package outline.	Identical mechanical fit and thermal interface; validated for same inverter topologies and gate drive conditions.	Select when legacy qualification data or existing thermal models for DD800S17K6C_B2 are already established.
FF800R17ME4	1700 V/800 A dual-diode module with EmCon4 technology; VF = 2.35 V (typ.), E_rec = 130 mJ (125°C), R_thJC = 32.5 K/kW.	Better softness and lower recovery loss; requires updated gate driver timing due to faster recovery.	Prefer for new designs targeting reduced switching loss and improved EMI profile in high-frequency PWM systems.

Compared with DD800S17K6C_B2 and FF800R17ME4, DD800S17HA_B2 offers identical voltage/current capability and isolation, but its higher E_rec demands more conservative snubber design, while its proven thermal model simplifies qualification in retrofit industrial drives.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The DD800S17HA_B2 is rated for continuous operation up to T_vj = 125°C. Its thermal resistance values (R_thJC = 34.0 K/kW per diode) and transient impedance curves are specified at this temperature, and derating is required beyond this limit per Infineon's application notes.

Does this module require external gate resistors for diode operation?

No-DD800S17HA_B2 contains only diodes and has no gate terminals. Gate resistors apply only to companion IGBT modules. This diode module connects directly between DC-link and inverter switch nodes without active control circuitry.

Can it be mounted directly onto an aluminum heatsink without insulating pads?

Yes-the module features reinforced basic insulation (IEC 61140 Class 1) and a 4.0 kV RMS isolation rating. Direct mounting on grounded aluminum heatsinks is permitted, provided surface flatness and torque (M6: 4.25–5.75 Nm) comply with Infineon's assembly guidelines.

What is the recommended thermal interface material for optimal R_thCH?

Infineon specifies R_thCH = 8.00 K/kW assuming λ_grease = 1 W/(m·K). Standard silicone-based thermal greases meeting this conductivity (e.g., Dow Corning TC-5122 or Shin-Etsu G746) are validated. Phase-change pads are not qualified for this module's mounting pressure profile.
