Infineon Technologies SIGC25T60UNX1SA3

Overview

SIGC25T60UN from Infineon Technologies is a 600 V, 30 A high-speed NPT IGBT die in bare-die format, designed for high-efficiency switching in medium-power converters. It features low E_off, positive temperature coefficient for stable paralleling, 100 µm chip thickness, and short-circuit ruggedness. Used in welding inverters, PFC stages, and UPS output stages where thermal cycling and dynamic loss optimization are critical.

For engineers reviewing the SIGC25T60UN datasheet, SIGC25T60UN pinout (emitter/gate/collector terminals), SIGC25T60UN application in PFC or welding inverters, or SIGC25T60UN equivalent bare-die IGBTs, this page delivers verified die-level specifications, mechanical layout, thermal behavior, and direct substitution guidance aligned with Infineon's SGP30N60HS module implementation.

Technical Context

This NPT (Non-Punch-Through) IGBT die employs a 100 µm thick silicon structure with photoimide passivation and Al–Si (1%) emitter metallization. Its 4.5 × 5.71 mm² active area supports 30 A DC collector current at T_j = 150 °C, with V_CE(sat) = 3.15 V @ 30 A and V_GE(th) = 4 V typical - enabling gate drive compatibility with standard +15 V logic.

Dynamic performance is characterized by t_d(off) = 122 ns and t_f = 29 ns under 400 V / 30 A inductive switching with 1.8 Ω gate resistance. C_iss = 1500 pF and C_rss = 92 pF at V_CE = 25 V confirm fast, controllable turn-off with low Miller feedback - critical for ZVS and high-frequency PFC designs.

FAQ

Is SIGC25T60UN supplied in tape-and-reel or waffle pack?

No - SIGC25T60UN is delivered as bare die on foil, not in carrier packaging. Each die is marked with a ∅0.65 mm ink dot and shipped in nitrogen-purged containers for moisture-sensitive handling. Customers must implement Class 1 ESD protocols and dry storage (<6 months at 23 °C) prior to die bonding.

What die attach methods are qualified for SIGC25T60UN?

Infineon specifies electrically conductive glue or soft solder (Sn–Ag–Cu or Sn–Pb) for collector-side attachment. Emitter metallization (Al–Si 1%) is compatible with aluminum wedge wire bonding ≤500 µm. Ni–Ag collector metallization supports both epoxy and solder die bonding without intermetallic degradation.

Does SIGC25T60UN require negative gate voltage for reliable turn-off?

No - the device operates reliably with 0 V gate turn-off (V_GE = 0 V). Its V_GE(th) = 4 V typical and positive temperature coefficient eliminate risk of spurious turn-on. Negative bias is unnecessary unless system-level noise exceeds 5 V peak-to-peak at the gate pad.

How does SIGC25T60UN relate to SGP30N60HS?

SIGC25T60UN is the bare-die version used inside the SGP30N60HS TO-220 packaged IGBT. All electrical and thermal specs match; differences are limited to packaging (no leadframe, no molding compound) and mechanical form factor (4.5 × 5.71 mm² die vs. TO-220 outline).
