Overview
The Nexperia BC858B,235 is a PNP general-purpose transistor housed in the SOT23 (TO-236AB) surface-mount package. It features a collector-emitter voltage of -30 V and a continuous collector current of -100 mA. The device provides a DC current gain range of 220 to 475 at VCE = -5 V and IC = -2 mA. Key electrical limits include a collector-base breakdown voltage of -30 V and an emitter-base voltage rating of -5 V. Total power dissipation reaches 250 mW at 25 °C ambient temperature.
Feature Summary
- Low current capability with a maximum collector current of 100 mA
- Low voltage operation with a maximum collector-emitter voltage of 65 V across the series
- Designed for general-purpose switching and amplification tasks
Applications
- General-purpose switching circuits
- Amplification applications
- Digital logic interface stages
Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel quantity configuration. Confirm that the component version aligns with non-automotive qualification requirements as specified in the latest product data sheet revision. Ensure compatibility with standard SOT23 footprints during PCB layout validation.
Selection Notes
Select this component when a PNP transistor with a -30 V collector-emitter voltage rating is required. The BC858B variant offers a tighter DC current gain band compared to lower-gain options. Verify that the thermal resistance characteristics meet the application's heat dissipation needs within the SOT23 package constraints.
Part Context
This part belongs to the BC856/BC857/BC858 family of low-voltage, low-current PNP transistors. The BC858B specifically denotes the -30 V collector-emitter voltage grade with a defined hFE range of 220 to 475. It serves as the PNP complement to the BC848B NPN transistor within the same manufacturing series.
