2SA733P

Single Bipolar Transistors Overview

The onsemi 2SA733P is a PNP silicon epitaxial planar transistor housed in a TO-92 plastic package. It features a maximum collector current of 150 mA and a collector-emitter breakdown voltage of 50 V. The device offers a transition frequency of 180 MHz and a power dissipation rating of 250 mW at 25°C ambient temperature. DC current gain ranges from 40 to 700, with an emitter-base voltage limit of 5 V and a collector-base voltage of 60 V.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for low-side switching applications
• Silicon epitaxial planar construction for reliability
• Through-hole mounting capability via TO-92 leaded package

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Switching circuits requiring moderate current handling
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'P' against the official datasheet to confirm pinout orientation and electrical tolerances. Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolescence notices or last-time buy notifications directly from onsemi channels before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 50V breakdown and 150mA continuous current is required in a through-hole format. Ensure the application operates within the 250mW thermal dissipation limits. Compare hFE requirements against the specified 40-700 range to determine if binning is necessary for consistent gain performance.

Single Bipolar Transistors Part Context

This part belongs to the KSA/2SA series of small-signal bipolar junction transistors. It serves as a standard replacement for legacy Japanese JIS-style PNP transistors in consumer electronics and industrial control designs. The TO-92 form factor ensures compatibility with existing printed circuit board layouts designed for general-purpose discrete semiconductors.

Single Bipolar Transistors Replacement Considerations

Direct equivalents include the KSA733YBU and generic 2SA733 variants. Verify pinout compatibility (Emitter-Base-Collector vs Collector-Base-Emitter) when substituting with other manufacturers' parts to prevent circuit damage.
