Product details
Overview
D1230N12TXPSA1 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 1230 A average on-state current at TC = 100 °C, 1200 V repetitive peak reverse voltage (VRRM), and 14.8 kA surge current (IFSM) with two-sided cooling. Its role is as a main-line freewheeling or line-commutated rectifier in 3-phase 6-pulse converters operating up to 180 °C junction temperature.
For engineers reviewing the D1230N12TXPSA1 datasheet, D1230N12TXPSA1 pinout, D1230N12TXPSA1 application, or D1230N12TXPSA1 equivalent, key selection criteria include thermal resistance (RthJC = 0.039 °C/W two-sided), on-state voltage (VF = 1.77 V at 3.2 kA), surge rating (IFSM = 14800 A), and clamping force requirement (6–15 kN) for reliable pressure-contact mounting.
Technical Context
This device is a non-controlled, bipolar power diode with planar passivated silicon die and double-sided copper baseplate construction. Its conduction behavior follows a defined on-state characteristic (vF = A + B·iF + C·ln(iF) + D·iF²) with slope resistance rT = 0.28 mΩ and threshold voltage V(TO) = 0.81 V at Tvj max.
Thermal performance is defined by transient impedance ZthJC curves for anode-, cathode-, and two-sided cooling configurations, with DC thermal resistance ranging from 0.035 to 0.093 °C/W depending on mounting orientation and current conduction angle (Θ = 30°–180°).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| IFAVM @ TC=100°C | 1230 A - Continuous DC forward current capability with two-sided heatsink cooling at 100 °C case temperature |
| IFSM @ tP=10 ms | 14800 A - Short-circuit withstand current for protection coordination with fast-acting fuses or circuit breakers |
| vF @ iF=3.2 kA | 1.77 V - Forward voltage drop defining conduction loss at rated overload current, critical for thermal design |

| Clamping Force | 6–15 kN - Required mechanical load to ensure low-contact-resistance interface between die and baseplates |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mounted power diode with isolated copper baseplates (anode and cathode terminals). No leaded or solderable package - requires mechanical clamping into heat sink assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud 1) | Forward current entry point | High-current input terminal; must be torqued to 6–15 kN clamping force for low RthCH and stable vF |
| Cathode (Stud 2) | Forward current exit point | High-current output terminal; electrically isolated from anode; forms complete conduction path with external busbar |
Key Features
| Feature | Design Value |
|---|---|
| Two-sided thermal path | Enables 30% higher power density vs. single-sided packages by halving effective RthJC to 0.039 °C/W |
| High IFSM rating | 14.8 kA surge capacity supports robust short-circuit protection in 6-pulse rectifier bridges without derating |
| Low slope resistance | rT = 0.28 mΩ ensures predictable, linear vF rise with current-critical for parallel operation stability |
| 180 °C junction rating | Allows operation in high-ambient environments (e.g., rail traction cabinets) without forced air or liquid cooling |

FAQ
What is the required clamping force for D1230N12TXPSA1 installation?
The device requires a mechanical clamping force between 6 kN and 15 kN to ensure low thermal resistance and stable electrical contact between the silicon die and copper baseplates. Under-torque increases RthJC and vF; over-torque risks die fracture. Torque must be applied evenly across both studs using calibrated hydraulic tools per Infineon's mounting guidelines.
Can D1230N12TXPSA1 be paralleled with other diodes?
Yes, but only with matched units from the same production lot and identical thermal mounting conditions. Its low slope resistance (rT = 0.28 mΩ) and defined on-state characteristic enable current sharing within ±5% when ΔTj ≤ 5 °C and interconnect inductance is balanced. External ballasting resistors are not recommended due to efficiency loss.
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature depends on cooling method and current waveform. With two-sided DC cooling, TC max = 100 °C supports 1230 A average current. At TC = 55 °C and Θ = 180° sin, it supports 1650 A. Exceeding TC limits reduces lifetime exponentially; junction temperature must never exceed 180 °C.
Does D1230N12TXPSA1 have a specified reverse recovery charge (Qr)?
Yes - Qr is characterized across di/dt from 100 A/µs to 10 kA/µs. At iFM = 1600 A, VR = 0.8·VRRM, and Tvj = 180 °C, Qr ranges from 100 µAs (at 100 A/µs) to 10,000 µAs (at 10 kA/µs). This data enables snubber design and EMI estimation in phase-controlled rectifier topologies.
