2SB1457(T6CANO,F,M

Single Bipolar Transistors Overview

The Toshiba Semiconductor and Storage 2SB1457 is a silicon PNP epitaxial type Darlington transistor designed for micro motor drive, hammer drive, power switching, and power amplifier applications. It features a high DC current gain of 2000 (min) at VCE = −2 V and IC = −1 A, alongside a low collector-emitter saturation voltage of −1.5 V (max) under the same conditions. The device operates with a maximum collector-emitter voltage of −100 V and supports a continuous collector current of −2 A in a JEDEC TO-92MOD package.

Single Bipolar Transistors Feature Summary

• High DC current gain capability reaching a minimum of 2000 at specified operating currents

Single Bipolar Transistors Procurement Notes

Verify RoHS compatibility status through official Toshiba sales representatives, as markings indicate specific lot number variations regarding environmental compliance. Confirm package authenticity matches the JEDEC TO-92MOD standard and validate absolute maximum ratings against your specific thermal management design requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when high current amplification is required within a compact form factor. The −100 V collector-emitter breakdown voltage accommodates moderate voltage levels, while the −2 A continuous current rating suits low-to-medium power loads. Ensure the application benefits from the inherent high gain to reduce base drive complexity.
