2SA1494

Single Bipolar Transistors Overview

The Sanken Electric 2SA1494 is a Silicon PNP Epitaxial Planar Transistor designed for audio and general-purpose applications. It serves as the complement to the 2SC3858 type. Key absolute maximum ratings include a collector-base voltage (VCBO) of -200 V, collector-emitter voltage (VCEO) of -200 V, emitter-base voltage (VEBO) of -6 V, continuous collector current (IC) of -17 A, base current (IB) of -5 A, and power dissipation (PC) of 200 W at Tc=25°C. The junction temperature range is -55°C to +150°C. Electrical characteristics specify a minimum DC current gain (hFE) of 50, with ranks Y (50-100), P (70-140), and G (90-180). Typical switching times in common emitter configuration are ton 0.6 ms, tstg 0.9 ms, and tf 0.2 ms.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank required (Y, P, or G) during procurement, as performance varies by bin. Confirm package compatibility with MT-200 dimensions. Note that this component is marked as not recommended for new designs; ensure existing supply chain agreements are valid before ordering.

Single Bipolar Transistors Selection Notes

Select based on required hFE bin for circuit symmetry when paired with complementary devices. Ensure thermal management supports the 200 W rating at case temperature. Verify voltage margins against the -200 V breakdown limits. Consider availability constraints due to the obsolescence status indicated in documentation.
