Product details

PNP switch with 250 minimum hFE at 100 mA — the gain spec that matters

The Infineon BC807-40E6433 is a PNP epitaxial planar transistor in the standard SOT-23-3 package (PG-SOT23-3-11). It is rated for a 45 V collector-emitter breakdown and 500 mA continuous collector current, with a 330 mW power dissipation limit. The 40 gain group guarantees a minimum DC current gain of 250 at 100 mA collector current and 1 V Vce — this is the spec that determines whether the device saturates hard enough for a relay coil, solenoid, or LED string at moderate drive current. The 200 MHz transition frequency means it can handle PWM switching into the low-MHz range without significant gain roll-off, making it usable as a pre-driver in a buck converter or class-D audio output stage.

Frequently asked questions

What is the hFE of BC807-40E6433 at 100 mA?

The minimum DC current gain (hFE) at 100 mA collector current and 1 V Vce is 250. This is the 40 gain-group rating — the device is guaranteed to deliver at least 250 at that bias point, which is the spec to check when driving a load that needs a hard saturation.

What is the maximum collector current of BC807-40E6433?

The maximum continuous collector current (Ic) is 500 mA. This is an absolute maximum rating — derate for ambient temperature and pulse conditions per the safe operating area guidelines in the datasheet.

Can I replace BC807-40 with BC807-40E6433?

Yes, the BC807-40E6433 is the standard Infineon order code for the BC807-40 gain group in SOT-23-3 package. The 'E6433' suffix is an Infineon internal ordering code that does not change the electrical or mechanical specification. It is a direct replacement for any BC807-40 in the same package.
