Product details
Overview
D970N06TXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium-voltage drive systems and traction applications. It delivers 970 A average on-state current at TC = 100 °C, supports 600 V repetitive peak reverse voltage (VRRM), and features a low 0.31 mΩ slope resistance (rT) at Tvj max, enabling efficient operation in dual- or single-sided cooled thyristor/diode stacks.
For engineers reviewing the D970N06TXPSA1 datasheet, D970N06TXPSA1 pinout, D970N06TXPSA1 application, or D970N06TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance under two-sided cooling (0.057 °C/W), surge current capability (10.3 kA @ 10 ms), and forward voltage drop (1.45 V @ 2.3 kA), all critical for high-reliability power conversion in rail traction and HVDC link interfaces.
Technical Context
This device operates as a unidirectional, non-controlled power rectifier with no gate control - its conduction is fully determined by applied anode-cathode voltage polarity and magnitude. It exhibits a defined on-state characteristic modeled by vF = A + B·iF + C·ln(iF) + D·iF², with coefficients A=0.4891, B=1.323×10⁻⁴, C=2.391×10⁻³, D=1.340×10⁻² at Tvj max.
Thermal performance is highly dependent on mounting configuration: two-sided cooling yields the lowest RthJC (0.057 °C/W), while anode- or cathode-side-only cooling increases it to 0.094–0.134 °C/W. Transient thermal impedance ZthJC follows a 7-term analytical model with time constants ranging from 133 µs to 3.23 s, supporting accurate short-duration overload analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines usable DC bus voltage range in 3-phase bridge rectifiers. |
| IFAVM @ TC=100°C | 970 A - continuous DC current rating under two-sided heatsink cooling; sets baseline for steady-state thermal design. |
| IFSM @ 10 ms | 10,300 A - non-repetitive surge current capacity; determines fuse coordination and short-circuit withstand in motor drives. |
| vF max @ 2.3 kA | 1.45 V - forward voltage at rated peak current; directly impacts conduction loss (P = I × vF) and thermal loading. |
| RthJC max (two-sided) | 0.057 °C/W - junction-to-case thermal resistance; enables calculation of maximum allowable case temperature rise under load. |
| I²t @ 10 ms | 530.45 × 10³ A²s - surge energy handling capability; used for I²t-based protection coordination with fast-acting fuses. |
| Tvj max | 180 °C - absolute maximum junction temperature; constrains thermal design margin and derating curves. |
Pinout & Package
Press-pack package with double-sided metal contact interface: Anode and Cathode are flat, copper-plated pressure-contact surfaces requiring mechanical clamping force of 3.8–7.6 kN. No leads or solderable terminals - mounted between heatsinks using insulated bolts and torque-controlled assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Must be thermally and electrically bonded to heatsink; surface finish and flatness critical for low RthCH and uniform current distribution. |
| Cathode | Current exit terminal during forward conduction | Same mounting requirements as Anode; asymmetry in cooling path (anode- vs cathode-side only) changes RthJC by up to 136%. |
Key Features
| Feature | Design Value |
|---|---|
| Low slope resistance | rT = 0.31 mΩ at Tvj max - minimizes forward voltage rise with current, reducing conduction losses in high-current DC links. |
| High surge current rating | IFS M = 10.3 kA @ 10 ms - supports robust short-circuit tolerance in industrial motor drives without external crowbar circuits. |
| Two-sided thermal optimization | RthJC = 0.057 °C/W - enables compact stack designs with symmetrical heat extraction, improving reliability over single-sided alternatives. |
| Controlled forward voltage profile | vF ≤ 1.45 V @ 2.3 kA - ensures predictable loss behavior across full operating range, simplifying thermal modeling. |
| High junction temperature rating | Tvj max = 180 °C - allows operation in harsh environments (e.g., rail underfloor, wind turbine nacelles) with reduced derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD900N06K | Same VRRM (600 V) and IFAVM (970 A), but higher vF (1.55 V @ 2.3 kA) and RthJC (0.062 °C/W); uses different pellet metallization. | Suitable for lower-cost industrial drives where 7% higher conduction loss is acceptable. | Select when cost sensitivity outweighs thermal efficiency; verify clamping force compatibility (3.5–7.0 kN). |
| D970N08TXPSA1 | Higher VRRM (800 V), identical IFAVM (970 A), same rT (0.31 mΩ), but increased RthJC (0.060 °C/W) due to thicker drift layer. | Required for 750 V DC bus systems (e.g., metro train auxiliary converters) where 600 V margin is insufficient. | Select only when 800 V blocking is mandatory; expect 5% higher thermal resistance and revised heatsink interface design. |
Compared with DD900N06K, D970N06TXPSA1 offers lower conduction loss and superior thermal resistance, making it preferred for high-efficiency traction systems; versus D970N08TXPSA1, it trades blocking voltage for better thermal performance - optimal for 600 V-class applications demanding maximum reliability.

FAQ
What is the required clamping force for D970N06TXPSA1 installation?
The datasheet specifies a mechanical clamping force of 3.8–7.6 kN across the anode and cathode surfaces. This range ensures optimal thermal contact and current sharing in press-pack stacks. Under-torque risks hot spots and premature failure; over-torque may deform copper contacts or damage internal Si pellet bonding. Use calibrated hydraulic tools and follow Infineon's mounting sequence per Application Note AN2015-03.
Can D970N06TXPSA1 be used in single-sided cooling configurations?
Yes - the datasheet provides validated RthJC values for anode-side-only (0.094 °C/W) and cathode-side-only (0.134 °C/W) cooling. However, power derating is required: at TC = 100 °C, IFAVM drops to 620 A (anode-side) and 420 A (cathode-side). Dual-sided cooling remains strongly recommended for full-rated performance and thermal symmetry.
What is the typical reverse recovery charge (Qr) at 800 A and -di/dt = 100 A/µs?
Per Figure 7 in the datasheet, Qr is 110 µAs at iFM = 800 A, -di/dt = 100 A/µs, Tvj = 180 °C, and vRM = 0.8 × VRRM. This value is critical for snubber design and EMI estimation in hard-switched rectifier topologies. Qr increases linearly with -di/dt up to 500 A/µs, then saturates near 220 µAs.
Does D970N06TXPSA1 comply with AEC-Q101 for automotive use?
No - this part is qualified to industrial and traction standards (IEC 60747-2, EN 50124-1), not AEC-Q101. Its 180 °C Tvj max and vibration resistance (50 Hz, 50 m/s²) meet rail and energy infrastructure requirements, but it lacks automotive-specific stress testing (e.g., temperature cycling, humidity bias). For EV traction inverters, consider Infineon's AEC-Q101-qualified IDH150E65D1 instead.
