Manufactured using Diffused Collector technology, it supports stable operation against base-drive circuit variations and provides very low worst-case dissipation. Key electrical ratings include VCBO up to 1500 V and thermal limits up to TJ 150°C, with DC current gain and switching characteristics specified for inductive-load tests.
