FAQ

Is BC807-25WE6327 pin-compatible with BC807-25W?

Yes. Both share identical SOT-323 (SC-70) pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. The "E6327" suffix denotes tape-and-reel packaging per EIA-481 standard, with no electrical or mechanical differences from BC807-25W.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is 100 mA, but for reliable long-term operation at I_C = 500 mA, the recommended base drive is 50 mA (h_FE = 10). Exceeding 50 mA risks thermal overstress and gain degradation, especially above 85 °C ambient.

Can BC807-25WE6327 replace BC807-16 in existing designs?

Yes, with verification. BC807-25WE6327 has higher minimum h_FE (160 vs. 100), enabling reduced base drive. However, ensure the circuit does not rely on lower gain for stability-especially in linear amplifiers-and confirm V_CE(sat) and thermal margins remain adequate.

Does this part support pulsed operation beyond its DC ratings?

Yes. Permissible pulse load curves show P_tot(max)/P_tot(DC) reaches 5× for t_p < 100 µs (duty cycle < 2%). At I_C = 1 A peak, pulses must be limited to <50 µs to stay within safe SOA boundaries defined by R_thJS and junction temperature limits.
