If you are looking for a reliable IGBT, Diode & SCR supplier in India, you have landed in the right place. Whether your industry needs new power semiconductor modules, refurbished IGBT modules, or obsolete SCR thyristors that were discontinued years ago — Jilan Automation Works, based in Bhavnagar, Gujarat, has been fulfilling these exact requirements since 2011.

This guide covers everything you need to know: what these components are, where they are used, how to identify the correct part, and why Indian industries — from Mumbai to Chennai, Pune to Ahmedabad — trust Jilan Automation for critical spare parts.

1. What Are IGBT, Diode and SCR Modules?

These three components are collectively known as power semiconductor devices. They form the backbone of modern industrial power electronics — controlling, converting, and regulating electrical energy at high voltages and currents.

IGBT (Insulated Gate Bipolar Transistor)

An IGBT module combines the easy voltage-controlled gate of a MOSFET with the high-current capacity of a bipolar transistor. This makes it ideal for fast switching applications such as AC drives (VFDs), solar inverters, UPS systems, induction heaters, and welding machines. IGBT modules are rated in voltage (typically 600V to 6500V) and current (up to 3600A).

Diode Module

A diode module allows current to flow in only one direction — making it the standard component for AC-to-DC rectification. In industrial drives, a three-phase diode bridge converts AC supply voltage into DC bus voltage, which is then inverted by IGBTs. Diode modules are rated by their repetitive peak reverse voltage (VRRM) and average forward current (IF).

SCR (Silicon Controlled Rectifier) / Thyristor

A SCR module, also called a thyristor, is a four-layer PNPN device used for controlled rectification and AC power regulation. Unlike a diode, an SCR requires a gate trigger signal to conduct — giving precise control over power delivery. SCRs are extensively used in induction furnaces, DC motor controllers, soft starters, and heating systems.

5. New, Refurbished & Obsolete Parts — What's the Difference?

At Jilan Automation Works, we stock all three categories to serve every budget and every situation:

New / Original Modules

Factory-fresh modules with full manufacturer warranty. Ideal when long-term reliability and full performance life are the priority. We source directly from authorised distributors or OEM channels.

Refurbished / Tested OK Modules

Carefully reconditioned modules that have undergone full bench testing including gate drive verification, thermal imaging, leakage current testing and saturation voltage check. Each refurbished module ships with a test report. This is a cost-effective option when the new module is expensive or has long lead times.

Obsolete / Hard-to-Find / Discontinued Modules

This is where Jilan Automation Works truly stands apart. When a part has been discontinued by the manufacturer, most suppliers simply cannot help. We maintain a global sourcing network specifically to find rare, end-of-life, and phased-out power semiconductor modules. Whether the part was discontinued 5 years ago or 20 years ago — just share the part number and our team will locate it.
