Product details
Overview
TZ240N30KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line commutation in industrial rectification and motor control systems. It delivers 240 A average on-state current (ITAVM) at TC = 85°C, supports 3000 V repetitive peak off-state voltage (VDRM/VRRM), and features 100 A/µs critical rate of rise of on-state current (diT/dt)cr - enabling robust gate-triggered turn-on in B2/B6 bridge configurations for medium-voltage DC drives.
For engineers reviewing the TZ240N30KOFHPSA1 datasheet, TZ240N30KOFHPSA1 pinout, TZ240N30KOFHPSA1 application, or TZ240N30KOFHPSA1 equivalent, key selection criteria include verified RMS current capability (700 A ITRMSM), transient thermal impedance ZthJC under sinusoidal conduction (Θ = 180°), gate trigger threshold (VGT ≤ 1.5 V), and isolation rating (3.0 kV RMS, 1 min).
Technical Context
This dual-thyristor module implements a press-pack, silicon-pellet-based B6-bridge topology with AlN ceramic internal insulation and direct pressure contact. Its 125 °C maximum junction temperature (Tvj max), 0.0745 °C/W junction-to-case thermal resistance (RthJC), and 350 µs circuit-commutated turn-off time (tq) are optimized for forced-air-cooled 6-pulse rectifiers operating at 50/60 Hz.
The device requires precise gate drive timing: maximum gate trigger delay (tgd) is 4.5 µs at 1 A gate current and 1 A/µs diG/dt, while non-trigger gate voltage (VGD) remains below 0.2 V at 0.5·VDRM - ensuring immunity to false triggering during high dv/dt transients up to 1000 V/µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3000 V - Repetitive peak forward/reverse blocking voltage; defines maximum AC line voltage compatibility in B6 rectifier topologies. |
| ITAVM @ TC = 85°C | 240 A - Average on-state current rating under standard heatsink conditions; sets continuous DC output capability in industrial drives. |
| ITRMSM | 700 A - Maximum RMS on-state current; determines thermal design margin for 180° conduction-angle operation. |
| (diT/dt)cr | 100 A/µs - Minimum required rate of rise for reliable turn-on without secondary breakdown; constrains gate driver slew rate design. |
| RthJC | 0.0745 °C/W - Junction-to-case thermal resistance under DC conditions; used to calculate case temperature rise from conduction losses. |
| tq | 350 µs - Circuit-commutated turn-off time at Tvj max; defines minimum commutation interval in line-synchronized inverters. |
| VISOL | 3.0 kV RMS (1 min) - Isolation test voltage between terminals and baseplate; certifies safety compliance for Class I equipment. |
Pinout & Package
Package: Press-pack, double-sided cooled thyristor module with isolated copper baseplate, AlN ceramic insulation, and M1 (6 Nm) mechanical mounting torque. Dimensions per datasheet page 3 (TZ240N series outline drawing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Main anode of first thyristor arm | Carries full-phase current in B2/B6 bridge; electrically isolated from baseplate via AlN. |
| Cathode 1 (K1) | Main cathode of first thyristor arm | Shared cathode node for two arms in common-cathode B6 configuration; connects to DC negative bus. |
| Anode 2 (A2) | Main anode of second thyristor arm | Phase-leg terminal for 3-phase input; polarity-matched to A1 for symmetrical thermal distribution. |
| Gate 1 (G1) | Control terminal for first thyristor | Receives low-energy pulse (≤250 mA IGT, ≤1.5 V VGT); referenced to K1 for isolated gate drive. |
| Gate 2 (G2) | Control terminal for second thyristor | Independent gate path; enables sequential firing in 6-pulse operation without cross-talk risk. |
| Baseplate | Thermal and electrical reference plane | Electrically isolated but thermally coupled to both dies; must be mounted with 6 Nm torque and thermal interface material. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT240N30KOFHPSA1 | Same package and VDRM/VRRM, but rated for 250 A ITAVM at TC = 85°C and 0.070 °C/W RthJC. | Higher average current rating enables lower thermal derating in natural-convection designs. | Select when higher continuous DC output is required and heatsink thermal budget allows tighter RthJC tolerance. |
| TZ240N32KOFHPSA1 | Identical thermal and gate specs, but with 3200 V VDRM/VRRM and 1000 V/µs (dv/dt)cr. | Better suited for 690 VAC+ systems with elevated transient overvoltage risk (e.g., marine or offshore grids). | Select when system-level surge protection is limited and higher blocking margin is mandated by grid code. |
Compared with TT240N30KOFHPSA1 and TZ240N32KOFHPSA1, TZ240N30KOFHPSA1 offers optimal balance of cost, thermal performance, and 3000 V blocking for standard 400–690 VAC industrial rectifiers - making it the default choice where strict 3200 V margin is not required.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC op) is +125 °C, as specified in the datasheet's operating temperature range (−40 °C to +125 °C). At this temperature, the device sustains 240 A average on-state current (ITAVM) under DC conduction with proper heatsink mounting and thermal interface material. Exceeding this limit risks irreversible junction damage due to thermal runaway.
Does TZ240N30KOFHPSA1 require a heatsink? If so, what thermal resistance is recommended?
Yes - a heatsink is mandatory. For natural cooling, the datasheet specifies KM17 (45 W) with 3 modules per heatsink and RthCH ≤ 0.02 °C/W. Under forced-air cooling (e.g., Papst 4650N), RthCA drops to 0.239 °C/W (transient) and 0.04 °C/W (steady-state), enabling full 700 A RMS operation. Thermal interface material must be applied uniformly at 6 Nm mounting torque.
Can TZ240N30KOFHPSA1 be used in anti-parallel configuration for AC output control?
No - TZ240N30KOFHPSA1 is a unidirectional thyristor module with separate anode/cathode terminals per arm, not a bidirectional triac or reverse-conducting thyristor. It is designed exclusively for phase-controlled rectification (B2/B6) and cannot block reverse voltage or conduct in reverse direction. Anti-parallel operation requires discrete back-to-back thyristors or dedicated AC switches.
What gate drive voltage and current are required for reliable turn-on?
A minimum gate trigger current of 250 mA (IGT max) at ≤1.5 V (VGT max) is required at 25 °C with 6 V anode-cathode voltage. Gate pulses must exceed 20 µs duration and maintain diG/dt ≥ 1 A/µs to ensure latching (IL = 1500 mA). The gate must be referenced to its respective cathode (K1/K2), not common ground, due to internal isolation.
