Product details

Overview

TT700N22KOFHPSA1 from Infineon Technologies is a pressure-contact thyristor module for phase-controlled AC power regulation, featuring V_DRM/V_RRM = 2200 V, I_TAVM = 700 A at T_C = 85°C, and R_thJC = 0.046 K/W per arm. It integrates electrically insulated baseplate and pre-applied TIM option, designed for high-reliability industrial rectifier and crowbar applications.

For engineers reviewing the TT700N22KOFHPSA1 datasheet, TT700N22KOFHPSA1 pinout, TT700N22KOFHPSA1 application, or TT700N22KOFHPSA1 equivalent, key selection criteria include repetitive peak voltage rating, RMS on-state current capability, junction-to-case thermal resistance, gate trigger characteristics, and pressure-contact packaging suitability for high-cycle industrial drives.

Technical Context

This thyristor module implements dual-arm, phase-control topology with symmetrical anti-parallel configuration for full-wave AC control. Its pressure-contact die attachment ensures stable thermal performance under high di/dt (200 A/µs) and dv/dt (1000 V/µs) stress, supporting reliable commutation in soft starters and static switches.

The device operates with gate-trigger current ≤250 mA and holding current ≤300 mA, enabling robust firing control across -40°C to +135°C case temperature range. Its analytical Z_thJC transient model supports precise thermal design for sinusoidal and rectangular conduction angles from 30° to 180°.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM/V_RRM	2200 V - maximum repetitive blocking voltage per arm, defining safe AC line voltage compatibility up to 1.5 kV RMS systems
I_TAVM	700 A @ T_C = 85°C - average on-state current per arm, setting continuous DC output capability in rectifier bridges
I_TSM	20400 A @ t_P = 10 ms - non-repetitive surge current, enabling short-circuit protection in crowbar circuits
R_thJC	0.046 K/W per arm - junction-to-case thermal resistance, determining minimum heatsink requirement for 700 A operation
V_T0 / r_T	0.85 V / 0.35 mΩ - threshold voltage and slope resistance, defining conduction loss profile below 1500 A
(di_T/dt)_cr	200 A/µs - critical rate of rise of on-state current, specifying minimum snubber design for turn-on stability
(dv_D/dt)_cr	1000 V/µs - critical rate of rise of off-state voltage, indicating immunity to false triggering in noisy industrial environments

Pinout & Package

TT700N22KOFHPSA1 uses an industrial-standard pressure-contact module package with 60 mm baseplate, AlN internal insulation, and Class 1 basic isolation per IEC61140. Mechanical mounting uses M1 screws (6 Nm torque), electrical terminals use M2 screws (12 Nm torque), and control terminals conform to DIN 46244 A (2.8 × 0.8 mm).

Pin/Terminal	Circuit Role	Design Meaning

K1 / A2	Cathode 1 / Anode 2	Main current path for second (anti-parallel) thyristor arm; enables bidirectional conduction in phase control
G1 / G2	Gate 1 / Gate 2	Isolated gate inputs for independent firing control of each arm; require ≤250 mA trigger current
Baseplate	Thermal & Electrical Reference	Electrically insulated (3.0 kV RMS, 1 min) but thermally conductive surface; serves as heatsink interface and safety ground reference

Key Features

Feature	Design Value

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
TD700N22KOF	Same V_DRM, I_TAVM, and R_thJC; differs only in marking code and production batch traceability	No functional difference; identical thermal and electrical specs; used interchangeably in same PCB footprints	Select when requiring alternate logistics coding or specific DMX traceability format
TT900N22KOF	Higher I_TAVM = 900 A at T_C = 85°C; identical V_DRM, R_thJC, and package dimensions	Enables higher continuous current in same footprint; requires recalculation of heatsink sizing and gate drive margin	Select when system demands >700 A average current and thermal headroom allows increased conduction loss

Compared with TD700N22KOF, TT700N22KOFHPSA1 offers identical performance with enhanced production traceability; versus TT900N22KOF, it trades 200 A current headroom for tighter gate drive requirements and lower conduction loss at nominal load.

FAQ

What is the maximum allowable junction temperature for TT700N22KOFHPSA1?

The maximum junction temperature (T_{vj max}) is 135°C, validated across all operating conditions including surge events. This rating enables operation with case temperatures up to 85°C at full 700 A load, provided thermal interface resistance remains ≤0.0075 K/W when using pre-applied TIM.

Does TT700N22KOFHPSA1 require forced-air cooling in standard applications?

No-natural convection cooling suffices for ITAV ≤ 400 A with R_thCA ≤ 0.2 K/W. At full 700 A rating, a heatsink with R_thCA ≤ 0.1 K/W and optional forced air (≥2 m/s) is recommended, based on Figure 7 in the technical information document.

Can TT700N22KOFHPSA1 be used in single-phase and three-phase topologies?

Yes-it supports both B2 two-pulse (single-phase) and B6 six-pulse (three-phase) bridge configurations. Its dual-arm anti-parallel structure allows full-wave control in either topology, with derating curves provided for conduction angles down to 30° in both cases.

What gate drive voltage and current are required for reliable triggering?

A minimum gate trigger voltage of 2.2 V and current of 250 mA at 25°C ensures turn-on under worst-case conditions. For robust operation across -40°C to +135°C, gate pulses must deliver ≥1 A peak for ≥20 µs with di_G/dt ≥ 1 A/µs, per IEC 747-6 compliance.
