Infineon Technologies BCP5216E6327HTSA1

Overview

BCP5216E6327HTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio-frequency driver and output stages. It features a 60 V collector-emitter breakdown voltage (V_(BR)CEO), 1 A continuous collector current (I_C), 0.5 V collector-emitter saturation voltage (V_CE(sat)) at I_C = 500 mA / I_B = 50 mA, DC current gain (h_FE) of 40–100 at I_C = 150 mA, and 125 MHz transition frequency (f_T). It is used in automotive amplifier biasing circuits requiring stable high-current switching.

For engineers reviewing the BCP5216E6327HTSA1 datasheet, BCP5216E6327HTSA1 pinout, BCP5216E6327HTSA1 application, or BCP5216E6327HTSA1 equivalent, key selection criteria include V_CE(sat) at high I_C, thermal resistance (R_thJS ≤ 15 K/W), AEC-Q101 qualification, SOT223 package footprint compatibility, and complementary NPN pairing with BCP54–BCP56 series.

Technical Context

This PNP transistor operates in linear and saturated switching modes with guaranteed h_FE ≥ 40 at I_C = 150 mA and V_CE = 2 V, and maintains V_CE(sat) ≤ 0.5 V under 500 mA/50 mA drive. Its f_T = 125 MHz supports moderate-speed switching in AF amplifiers and power control feedback paths.

Thermal design is enabled by R_thJS ≤ 15 K/W and P_tot = 2 W at T_S ≤ 120 °C, with pulse capability up to 1.5× I_CM (1.5 A) for t_p ≤ 10 ms. It is qualified per AEC-Q101 for automotive underhood environments.

Key Specifications

Pinout & Package

FAQ

Is BCP5216E6327HTSA1 pin-compatible with BCP52-16?

Yes-both share identical SOT223 pinout (Emitter–Collector–Base–Collector Tab) and identical electrical specifications. The suffix "E6327HTSA1" denotes Infineon's standardized tape-and-reel packaging (1000 pieces per 180 mm reel) with full traceability; "-16" is an older marking variant without explicit packaging code. No layout or schematic changes are needed for substitution.

What is the maximum allowable junction temperature during pulsed operation?

The absolute maximum junction temperature remains 150 °C regardless of pulse duration. Under pulsed conditions (t_p ≤ 10 ms, duty cycle < 2%), the device can sustain I_CM = 1.5 A while staying within thermal limits, provided the average power (I_C(rms)² × R_DS(on) equivalent) does not exceed 2 W and board-level thermal resistance keeps T_J ≤ 150 °C.

Can BCP5216E6327HTSA1 replace BC857 in SOT23 footprint designs?

No-it uses SOT223 (6.5 × 3.5 mm), not SOT23 (3.0 × 1.4 mm). Pin count and thermal pad differ fundamentally. While both are PNP transistors, BCP5216E6327HTSA1 delivers 1 A continuous current and requires PCB copper area for heat dissipation; BC857 is rated for 100 mA and fits passive-pad-only layouts. Mechanical and thermal incompatibility prevents drop-in replacement.

Does this transistor support operation at −55 °C ambient?

Yes-the storage temperature range is −65 °C to +150 °C, and electrical characteristics are specified down to −55 °C in Infineon's extended characterization data. At −55 °C, h_FE decreases by ~25% and V_BE(ON) increases by ~100 mV versus 25 °C, but all parameters remain within functional bounds for automotive cold-cranking scenarios.
