Product details
Overview
D770N16TXPSA1 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 inverters. It delivers 770 A average on-state current at TC = 100 °C, supports 1600 V repetitive peak reverse voltage (VRRM), and withstands 7700 A surge current (IFSM) at tP = 10 ms - enabling use in 3-level NPC converters for rail propulsion.
For engineers reviewing the D770N16TXPSA1 datasheet, D770N16TXPSA1 pinout, D770N16TXPSA1 application, or D770N16TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (RthJC ≤ 0.057 °C/W two-sided), forward voltage drop (vF ≤ 1.76 V at 1.6 kA), and transient thermal impedance behavior under sinusoidal conduction angles.
Technical Context
This device operates as a unidirectional, non-controlled power rectifier with a planar, diffusion-processed silicon die mounted in a double-sided cooled, pressure-contact package. Its on-state characteristic follows vF = A + B·iF + C·ln(iF) + D·iF² (with published coefficients), and its reverse recovery charge Qr ranges from 25 µAs to 10,000 µAs depending on di/dt and iFM.
Thermal performance is defined by dual-path heat flow: junction-to-case resistance varies with cooling configuration (anode-, cathode-, or two-sided), and transient impedance ZthJC is modeled analytically using seven RC network elements - critical for predicting junction temperature rise during short-duration overload pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V - maximum repetitive reverse blocking voltage; defines usable DC link voltage range up to 1200 V nominal in 3-phase rectifiers |
| IFAVM @ TC=100°C | 770 A - continuous DC current rating under forced two-sided cooling; sets base thermal design point for heatsink sizing |
| IFSM @ tP=10 ms | 7700 A - non-repetitive surge capability; supports short-circuit ride-through in motor drives without fuse blow |
| vF max @ iF=1.6 kA | 1.76 V - forward voltage at rated pulse current; directly determines conduction loss (≈2.8 kW per device at full load) |
| RthJC max (two-sided) | 0.057 °C/W - thermal resistance from junction to case surface; enables <100 °C junction rise above 100 °C case temp at full IFAVM |
| Tvj max | 180 °C - maximum allowable junction temperature; allows operation in high-ambient environments like locomotive underfloor enclosures |
| Qr @ iFM=800 A | 100–10,000 µAs - recovered charge dependent on -di/dt; impacts snubber sizing and commutation losses in hard-switched topologies |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mount diode with isolated anode and cathode terminals. Requires mechanical clamping force of 3.2–7.6 kN. Weight: 75 g. Creepage distance: 10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (stud) | Current entry point under forward bias | Electrically isolated metal stud; serves as primary heat path and high-current interface - must be torqued to specified clamping force |
| Cathode (stud) | Current exit point under forward bias | Electrically isolated metal stud; completes dual thermal path - requires identical mounting pressure and thermal interface material |
Key Features
| Feature | Design Value |
|---|---|
| Double-sided thermal path | RthJC ≤ 0.057 °C/W enables >90% of total heat extraction via both terminals - reduces hotspot formation in stacked assemblies |
| High IFSM / IFAVM ratio | 10:1 surge-to-continuous rating supports 10-cycle short-circuit tolerance without degradation - eliminates need for fast-acting fuses in many traction designs |
| Controlled reverse recovery | Qr < 100 µAs at low di/dt (≤100 A/µs) minimizes turn-off switching loss and EMI in phase-controlled rectifiers |
| Extended Tvj rating | 180 °C max junction temperature permits operation at elevated ambient (e.g., 70 °C cabinet) while maintaining 15 K safety margin |
Applications
| Rail Traction Inverter | Medium-Voltage Industrial Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD700N16K | Same VRRM (1600 V), lower IFAVM (700 A @ TC=100°C), higher RthJC (0.062 °C/W) | Suitable for lower-duty-cycle applications where peak current dominates over continuous rating | Select when thermal budget allows 0.005 °C/W higher junction rise or when cost sensitivity outweighs 9% current derating |
| SKKT 700/16E | Higher VRRM (1800 V), same IFAVM (770 A), integrated gate driver not applicable - this is a diode-only part | Designed for thyristor-based phase-controlled rectifiers requiring tighter voltage margin | Choose only if system requires ≥1800 V blocking or compatibility with legacy SKKT mounting footprints |
Compared with DD700N16K and SKKT 700/16E, D770N16TXPSA1 offers optimal balance of continuous current (770 A), thermal resistance (0.057 °C/W), and surge robustness (7700 A) - making it preferred for high-duty-cycle, forced-cooled industrial rectification where reliability under sustained load is critical.

FAQ
What clamping force is required for reliable thermal and electrical contact?
The D770N16TXPSA1 requires a mechanical clamping force between 3.2 kN and 7.6 kN applied evenly across both anode and cathode studs. Insufficient force increases contact resistance and thermal impedance, risking localized overheating and premature failure. Force must be verified with calibrated torque tools during assembly.
Does this diode have a specified reverse recovery time (trr)?
No - the datasheet does not specify trr. Instead, it provides recovered charge (Qr) as a function of di/dt and peak forward current, along with analytical models for ZthJC. Designers must derive effective recovery behavior from Qr and circuit conditions, not fixed trr values, due to the device's soft recovery profile.
Can D770N16TXPSA1 be paralleled for higher current capacity?
Yes, but only with strict matching: identical mounting pressure, thermal interface material, busbar symmetry, and current-sharing inductors. The device's positive temperature coefficient of vF supports natural current sharing, but layout asymmetry can cause >25% current imbalance - requiring individual thermal monitoring in production units.
Is lead-free soldering compatible with this package?
Not applicable - the D770N16TXPSA1 uses a pressure-contact, stud-mounted mechanical interface, not soldered terminations. Thermal interface materials (e.g., thermal greases or phase-change pads) must comply with RoHS and be qualified for 180 °C peak service temperature.
