Product details

Device identity and key parametrics

The BC 846B B5003 is a general-purpose NPN bipolar junction transistor in a surface-mount SOT-23-3 package (TO-236-3 / SC-59). It is part of the BC 846 series, with the B suffix denoting a tighter DC current gain bin. The minimum DC current gain (hFE) is 200 at 2 mA collector current and 5 V VCE, and the transition frequency (fT) is 250 MHz.

No official replacement or successor order code is provided in the manufacturer's lifecycle data.

The 65 V V(BR)CEO provides margin for supply rails. The 100 mA continuous collector current suits low-power switching. The minimum hFE of 200 at 2 mA means the base drive requirement is relatively low for a given collector current, simplifying the drive circuit design. The 250 MHz fT supports analog amplification up to VHF frequencies and fast switching in low-power converters. The SOT-23-3 footprint is a standard small-signal package. The 330 mW power limit must be derated for ambient temperature.

Frequently asked questions

Where can I buy BC 846B B5003 today?

BC 846B B5003 is obsolete and sourced through independent distribution. Submit an RFQ for current availability and pricing; quotes are confirmed at order time.

What is the replacement for BC 846B B5003?

No official replacement order code is provided in the manufacturer's lifecycle data. A functionally equivalent NPN transistor in SOT-23-3 with 65 V VCEO, 100 mA Ic, and hFE min 200 would be a candidate, but pin-for-pin compatibility and electrical fit must be verified against the specific application requirements.

Is BC 846B B5003 equivalent to BC 846B without suffix?

The BC 846B B5003 is a specific ordering code variant of the BC 846B base type. The B5003 suffix typically denotes packaging and reel specifications. The electrical characteristics (65 V, 100 mA, hFE min 200) are common to the BC 846B family, but the suffix may affect tape-and-reel quantities or shipping format.
