Infineon Technologies IRGP30B120KD-EP

Overview

IRGP30B120KD-EP from Infineon Technologies is a 1200 V, 60 A N-channel insulated gate bipolar transistor (IGBT) with co-packaged ultrafast soft-recovery anti-parallel diode in TO-247AD package. It delivers V_CE(on) = 2.28 V (typ.) at 25 A/15 V/25°C, 10 μs short-circuit capability, and square RBSOA - optimized for high-efficiency motor control inverters operating up to 150°C junction temperature.

For engineers reviewing the IRGP30B120KD-EP datasheet, IRGP30B120KD-EP pinout, IRGP30B120KD-EP application, or IRGP30B120KD-EP equivalent, key selection criteria include its low conduction loss, ultrasoft diode recovery (t_rr = 300 ns, Q_RR = 5100 nC), 120 A pulsed current rating, and extended lead TO-247AD mechanical design for improved thermal mounting and EMI reduction.

Technical Context

This IGBT employs Non-Punch-Through (NPT) technology with positive V_CE(on) temperature coefficient and benchmark efficiency for 3-phase motor drives. Its integrated diode features low V_F = 1.76 V (typ. @ 25 A/25°C) and low reverse recovery energy (E_rec = 1820 μJ @ 125°C), enabling reduced snubber requirements and lower system EMI.

The device supports full-square RBSOA up to 1000 V and 120 A, with 10 μs short-circuit safe operating area (SCSOA) at 900 V. Gate charge parameters (Q_g = 254 nC typ., Q_gc = 123 nC) and switching losses (E_on = 1250 μJ, E_off = 1800 μJ @ 25°C) are characterized across 25–125°C for robust inverter design.

Key Specifications

Pinout & Package

IRGP30B120KD-EP uses the extended-lead TO-247AD package (JEDEC TO-247 variant with longer leads for easier PCB clearance and thermal pad access). The package is lead-free and rated for 300°C soldering (10 s, 1.6 mm from case).

FAQ

What is the maximum allowable gate-emitter voltage for IRGP30B120KD-EP?

The absolute maximum gate-emitter voltage is ±20 V. Operation beyond this range risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and –5 V to –10 V for turn-off to ensure robust noise immunity and prevent spurious turn-on during high dV/dt transitions.

Does IRGP30B120KD-EP require an external freewheeling diode?

No - it integrates an ultrafast soft-recovery anti-parallel diode rated for 30 A continuous forward current at 100°C case temperature. This eliminates the need for discrete diodes in standard inverter half-bridge configurations, reducing PCB area and parasitic inductance.

How does the 10 μs short-circuit capability translate to real-world protection?

The device sustains rated current at 900 V for 10 μs without latch-up or second breakdown. This provides sufficient time for gate driver fault detection circuitry (e.g., desaturation sensing) to trigger shutdown before thermal runaway occurs - a critical safety margin in motor drive fault handling.

What thermal interface material is recommended for mounting IRGP30B120KD-EP?

A thermally conductive, electrically insulating grease (e.g., Dow Corning TC-5623 or Parker Chomerics T-grease 3600) applied at 0.1–0.15 mm thickness is recommended. The R_θCS = 0.24 °C/W specification assumes flat, greased mounting surface - uneven surfaces or dry mounting degrade thermal performance by ≥40%.
