2SA2180

Single Bipolar Transistors Overview

The Sanyo 2SA2180 is a high-voltage PNP silicon power bipolar transistor designed for demanding switching applications. It features a collector-emitter breakdown voltage of 450V and a maximum continuous collector current of 15A. The device utilizes a TO-218 flange-mount package with plastic/epoxy encapsulation, supporting through-hole termination. It is rated for a maximum power dissipation of 140W and includes a minimum DC current gain (hFE) of 30. The component is specified for single-element configuration and operates up to a junction temperature of 150°C.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as Sanyo Semiconductor assets were acquired by ON Semiconductor. Ensure the part number matches the original Sanyo specification sheet rather than potential legacy or rebranded equivalents from other distributors. Confirm the package type is TO-218 and check for any specific suffix variations that might indicate different binning or testing criteria. Request datasheets directly from authorized channels to validate electrical parameters against the original 450V/15A specifications.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is required for power switching applications. The 450V rating distinguishes it from lower-voltage alternatives like the 2SB922 series. Consider the TO-218 package for heat sink mounting requirements. Compare hFE minimums with similar devices if base drive current is limited. Ensure the application voltage does not exceed the V(BR)CEO limit under all transient conditions.

Single Bipolar Transistors Part Context

The 2SA2180 belongs to the Sanyo high-voltage PNP transistor family, often paired with NPN counterparts like the 2SC3153 or 2SC4109 in complementary bridge configurations. These devices are typically used in audio predriver stages and high-power switching regulators. The TO-218 form factor is standard for medium-to-high power discrete transistors requiring direct heatsink attachment.

Single Bipolar Transistors Replacement Considerations

Check for cross-reference availability from ON Semiconductor, which acquired Sanyo's semiconductor business. Verify pinout compatibility and thermal resistance values before substituting with generic high-voltage PNP transistors.
