Architected using Sanyo’s proprietary insulated metal substrate technology, the module bridges the gap between discrete transistor setups and monolithic ICs. The key parameters routinely listed in the technical datasheet include:

Sometimes you will see part numbers like STK412-530 or STK412530-S. Often, the 'S' indicates a slightly different internal thermal shutdown characteristic or pin configuration. Always try to match the number exactly as printed on your original unit. If you cannot find an exact match, consult a cross-reference guide, as some STK series are interchangeable.

: Includes internal thermal protection and short-circuit protection circuits to prevent damage during fault conditions. Hybrid Design

The STK412530 comes in a 16-pin SIP (Single Inline Package) with a staggered lead pitch. Below is the pin assignment as listed in the datasheet:
