Infineon Technologies BCP5116E6327HTSA1

Overview

BCP5116E6327HTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio-frequency driver and output stages. It features 45 V V_CEO, 1 A continuous collector current, 0.5 V typical V_CE(sat) at I_C = 500 mA/I_B = 50 mA, h_FE of 100–250 (at I_C = 150 mA), and SOT-223 surface-mount package. It is used in low-voltage linear amplification and switching in automotive body control modules.

For engineers reviewing the BCP5116E6327HTSA1 datasheet, BCP5116E6327HTSA1 pinout, BCP5116E6327HTSA1 application, or BCP5116E6327HTSA1 equivalent, key selection criteria include guaranteed h_FE range at high I_C, low saturation voltage under 50 mA base drive, thermal resistance ≤15 K/W (junction-to-soldering point), AEC-Q101 qualification, and complementary NPN pairing with BCP54–BCP56 series.

Technical Context

This PNP transistor operates in linear and saturated switching modes with DC current gain specified across three test conditions: 25–100 at I_C = 5 mA, 40–160 at I_C = 150 mA (BCP51-16 variant), and up to 250 at I_C = 500 mA. Its f_T of 125 MHz supports stable operation in AF bandwidths without unintended RF oscillation.

Thermal design relies on R_thJS ≤15 K/W and derating curves showing P_tot = 2 W at T_S ≤120°C, with pulse capability up to 10× DC rating for t_p ≤10 ms. The device meets AEC-Q101 stress testing for automotive under-hood use.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature (T_j) is 150°C. Operation must remain within this limit under all conditions, including ambient temperature, PCB copper area, and airflow. Derating begins at T_S = 120°C, where total power dissipation drops linearly to zero at 150°C junction temperature per the datasheet thermal curve.

Is BCP5116E6327HTSA1 pin-compatible with NPN counterparts like BCP54?

No-BCP5116E6327HTSA1 (PNP) and BCP54 (NPN) share the same SOT-223 package outline and pin numbering (B-C-E-C), but their polarity and biasing requirements differ fundamentally. Circuit redesign is required to substitute one for the other; they are complementary-not interchangeable-devices.

Does this part support pulsed operation beyond its DC ratings?

Yes-pulse testing confirms safe operation up to I_CM = 1.5 A for t_p ≤10 ms with duty cycle D < 2%. The permissible pulse load ratio (P_tot(max)/P_tot(DC)) reaches 10× at t_p = 100 µs, provided thermal mass and PCB layout prevent cumulative heating.

How does the SOT-223 package improve thermal performance over SOT-23?

The SOT-223's exposed collector tab (pin 4) provides direct thermal conduction to the PCB, achieving R_thJS ≤15 K/W-nearly 3× better than typical SOT-23 R_thJA. This allows 2 W dissipation at T_S = 120°C versus ~0.35 W for SOT-23 under identical board conditions, enabling higher current operation without heatsinks.
