This document describes the features and characteristics of the SAP series products, including built-in temperature compensation diodes and emitter resistor, real-time temperature compensation, etc. The new design ensures symmetrical layout for PNP and NPN pins, reducing output distortions. The product is suitable for audio amplifier applications.
The document describes a series of Darlington transistors (SAP15P/N, SAP10P/N, SAP08P/N) designed specifically for audio amplifiers. These components integrate temperature compensation diodes and an emitter resistor into a single package to eliminate thermal runaway and stabilize idle current.
Key features include real-time temperature detection via on-chip diodes, symmetrical PNP and NPN pinouts, and reduced parts count. The datasheet provides electrical characteristics, recommended operating conditions for adjusting idle current using external variable resistors, application notes for parallel push-pull configurations, and safety information regarding the destruction capacity of the built-in emitter resistor.

The idle current should be adjusted to 40mA using an external variable resistor.
The recommended variable resistor value ranges from 0 to 200 Ohms.
The forward current flowing over the diodes should be adjusted at 2.5mA.
