Product details

Automotive-grade PNP transistor in SOT-23-3

It comes in the standard SOT-23-3 surface-mount package (PG-SOT23-3-1), which fits the common footprint for small-signal transistors used in switching, amplification, and driver stages. The 250 MHz transition frequency supports switching speeds needed for gate drive buffers, relay coil drivers, and signal conditioning up to low-MHz ranges. With a DC current gain (hFE) minimum of 220 at 2 mA collector current and 5 V Vce, the BC856BE6327 provides consistent gain for analog stages and ensures reliable saturation in digital switching. The 650 mV Vce saturation at 5 mA base and 100 mA collector keeps on-state losses low in saturated switch applications.

AEC-Q101 and 150 °C junction rating

The maximum junction temperature of 150 °C allows operation in under-hood and engine-adjacent environments where ambient temperatures can exceed 105 °C. The 15 nA maximum collector cutoff current ensures low leakage at elevated temperatures, critical for high-impedance nodes. Lifecycle status is listed as Active, so there is no end-of-life or last-time-buy risk for current or new designs.

SOT-23-3 footprint and MSL handling

The SOT-23-3 package (PG-SOT23-3-1) is the industry-standard three-lead small-signal transistor footprint. Standard moisture sensitivity level (MSL) for SOT-23-3 is typically MSL 1, but confirm the date code's MSL rating from the reel label before reflow; if the part has been exposed to ambient humidity beyond the floor life, a bake-out per J-STD-033 is required to prevent popcorning.

Frequently asked questions

Is BC856BE6327 equivalent to BC856B or what are the differences?

The BC856BE6327 is functionally equivalent to the standard BC856B — both are PNP transistors with the same 65 V Vce, 100 mA Ic, and 250 MHz fT ratings. The BC856BE6327 suffix indicates the AEC-Q101 automotive qualification and the specific Infineon ordering code (Bulk packaging, SOT-23-3). The BC856B without the suffix may lack the automotive stress testing. For non-automotive designs, the BC856B is a drop-in replacement; for automotive or high-reliability applications, use the BC856BE6327.

Can BC856BE6327 replace a failed BC857B in an existing circuit?

The BC856BE6327 is a PNP transistor like the BC857B, but the BC857B typically has a lower Vce breakdown (45 V) and different gain grouping. The BC856BE6327 has a 65 V Vce breakdown, so it can replace a BC857B in circuits where the supply voltage does not exceed 45 V, but the higher breakdown voltage is acceptable. Check the circuit's bias conditions: the BC856BE6327 has a minimum hFE of 220 at 2 mA, which may differ from the BC857B's gain range. If the circuit is designed for the BC857B's specific gain, test the replacement at the operating point.
