The NEC 2SA1220/2SA1220A and 2SC2690/2SC2690A are silicon epitaxial PNP/NPN transistors intended for low‑frequency and high‑frequency power‑amplifier applications. They are suitable for driver stages in audio, high‑frequency power amplifiers, and TV vertical output stages.
The sheet provides key electrical parameters such as collector current, power dissipation, voltage ratings, and pulse‑width limits, together with the physical package dimensions and pin configuration (Emitter, Collector, Base). This manual is written in Japanese.
| Maximum collector‑emitter voltage (VCE) | 150 V |
|---|---|
| Pulse width (PW) | 10 ms |
| Duty cycle (DC) | 50 % |
The collector‑emitter voltage rating is 150 V.
A pulse width of 10 ms with a 50 % duty cycle is specified.
