FAQ

What is the maximum operating temperature for BCR158E6327HTSA1?

The junction temperature (T_j) must not exceed 150 °C. The device is rated for storage between −65 °C and +150 °C, and its thermal resistance (R_thJS ≤ 240 K/W) defines safe power derating above T_S = 102 °C in SOT23 mounting.

Can BCR158E6327HTSA1 replace a standard PNP BJT like BC807?

No-it cannot directly replace discrete BJTs because it includes internal bias resistors. Unlike BC807, BCR158E6327HTSA1 requires only one input signal (no external base resistor), making it incompatible with circuits expecting three-terminal BJT biasing.

Is BCR158E6327HTSA1 suitable for PWM-driven loads?

Yes-its f_T = 200 MHz and t_on/t_off < 100 ns support PWM frequencies up to 10 MHz. V_CE(sat) ≤ 0.3 V ensures low conduction loss at 50% duty cycle with I_C = 10 mA.

Does BCR158E6327HTSA1 support 3.3 V logic-level drive?

Yes-its V_i(on) range (0.5–1.1 V) and V_i(off) (0.4–0.8 V) ensure robust recognition of 3.3 V CMOS logic thresholds, allowing direct connection to microcontrollers without level-shifting circuitry.
