Product details

Overview

TT250N16KOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module with pressure-contact construction, rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 250 A average on-state current at TC = 85 °C, and 9100 A non-repetitive surge current (ITSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and is designed for high-reliability industrial power control in soft starters and drive rectifiers.

For engineers reviewing the TT250N16KOFTIMHPSA1 datasheet, TT250N16KOFTIMHPSA1 pinout, TT250N16KOFTIMHPSA1 application, or TT250N16KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W per arm), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and crowbar-capable surge handling (9100 A, 10 ms).

Technical Context

This dual-thyristor module implements a press-pack, double-sided cooled design with AlN ceramic isolation and silicon die mounted via pressure contact-eliminating wire bonds and solder fatigue. Its 180° conduction capability supports full-wave AC phase control, while the 125 °C maximum junction temperature and 0.7 mΩ slope resistance enable stable operation under high RMS load conditions.

The module integrates two anti-parallel thyristor arms in a single industrial-standard package, supporting both B2 (two-pulse) and B6 (six-pulse) bridge configurations. Gate drive requirements are defined by standardized triggering thresholds (VGT ≤ 2 V, IGT ≤ 200 mA) and robust immunity to false turn-on (VGD ≤ 0.2 V, (dvD/dt)cr = 1000 V/µs).

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM / VRRM	1600 V - Maximum repetitive blocking voltage per thyristor arm, enabling use in 690 V AC line-fed drives with safety margin.
ITAVM (TC = 85 °C)	250 A - Continuous DC-equivalent current per arm, defining steady-state thermal limits in rectifier or controller topologies.
ITSM (10 ms)	9100 A - Non-repetitive surge current capacity, supporting crowbar protection and motor-start inrush handling.
RthJC (per arm)	0.124 K/W - Junction-to-case thermal resistance under DC conditions, directly determining heatsink sizing for 125 °C max Tj.
(dvD/dt)cr	1000 V/µs - Critical rate-of-rise of off-state voltage, ensuring reliable commutation in inductive load switching.
V(TO) / rT	0.8 V / 0.7 mΩ - Threshold voltage and slope resistance, jointly defining forward conduction loss profile up to 800 A.
IGT / VGT	≤200 mA / ≤2 V - Maximum gate trigger current/voltage at 25 °C and 12 V anode-cathode voltage, setting driver strength requirement.

Pinout & Package

TT250N16KOFTIMHPSA1 uses an industrial-standard press-pack module housing with electrically insulated baseplate (Class 1, EN61140), AlN internal insulation, and M1 (5 Nm) mechanical mounting points. Dimensions and terminal layout conform to Infineon's standard 50 mm baseplate footprint.

Pin/Terminal	Circuit Role	Design Meaning
A1 / K2	Anode of Arm 1 / Cathode of Arm 2	Common AC input node for anti-parallel configuration; carries full line current in B2/B6 bridges.
K1 / A2	Cathode of Arm 1 / Anode of Arm 2	Common AC output node; connects to load or DC bus in phase-controlled rectification.
G1 / G2	Gate terminals (Arm 1 / Arm 2)	Isolated low-energy control inputs; require ≤2 V, ≤200 mA pulses with <3 µs delay for synchronized firing.
Baseplate	Electrically isolated case / thermal path	Provides primary heat dissipation path (RthCH = 0.030 K/W with TIM); rated for 3.6 kV insulation test (1 sec).

Key Features

Feature	Design Value
Pressure-contact die attachment	Eliminates bond-wire failure mechanisms and enables >10⁶ thermal cycles without degradation.
Pre-applied TIM layer	Reduces RthCH by ≥25% vs. bare surface mounting, simplifying thermal interface assembly and improving repeatability.
Double-sided cooling support	Enables symmetric heat extraction from both top and bottom surfaces, increasing effective thermal mass utilization.
Anti-parallel dual-arm integration	Provides complete AC quadrant control in one module-no external paralleling or matching required for bidirectional conduction.
High dv/dt immunity (1000 V/µs)	Ensures noise-immune operation in EMI-heavy industrial environments without snubber circuits in many applications.

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
TT250N16KOF	No pre-applied TIM; RthCH = 0.04 K/W (vs. 0.03 K/W with TIM)	Requires user-applied thermal paste; less suitable for high-volume automated assembly	Select when thermal interface process is already established and cost sensitivity outweighs TIM convenience.
TT330N16KOF	Higher ITAVM (330 A), same VDRM/RthJC architecture, 100 g heavier	Supports higher continuous current but requires larger heatsink and mounting hardware	Select when system-level derating demands >250 A margin or future-proofing for load growth is required.

Compared with TT250N16KOF, TT250N16KOFTIMHPSA1 reduces thermal interface assembly steps and improves thermal repeatability; compared with TT330N16KOF, it offers tighter footprint and lower weight while meeting standard 250 A industrial drive requirements.

FAQ

What is the maximum allowable junction temperature for TT250N16KOFTIMHPSA1?

The absolute maximum junction temperature (Tvj max) is 125 °C, validated per IEC 60747-6. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that under worst-case ITAVM and ambient conditions, junction temperature remains ≤125 °C using the provided ZthJC transient curves and RthCH values.

Does TT250N16KOFTIMHPSA1 require forced air or liquid cooling?

No mandatory forced cooling is specified; the module is designed for conduction-cooled operation via its insulated baseplate. Effective heatsinking-using a flat, smooth surface with ≤0.030 K/W RthCH (with TIM) and adequate thermal mass-is sufficient for 250 A ITAVM at TC ≤ 85 °C. Forced air or liquid cooling may extend current capability but is not required for nominal ratings.

Can TT250N16KOFTIMHPSA1 be used in parallel configurations?

Parallel operation is not recommended. The module integrates two matched thyristor arms in a single press-pack structure optimized for balanced current sharing. External paralleling introduces mismatch risks in dynamic parameters (di/dt, dv/dt, tq), gate threshold, and thermal coupling-potentially causing current hogging and premature failure. Use higher-current variants (e.g., TT330N16KOF) instead.

What gate drive voltage and current are required for reliable turn-on?

A minimum gate pulse of 12 V with ≥200 mA peak current is required to guarantee turn-on across temperature and aging. The datasheet specifies VGT ≤ 2 V and IGT ≤ 200 mA at 25 °C, but design margins demand ≥12 V to overcome circuit impedance and ensure <3 µs tgd even at Tvj = 125 °C. Gate resistor selection must limit di/dt to avoid false triggering.
