Infineon Technologies BCP5216H6327XTSA1

Overview

BCP5216H6327XTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio-frequency driver and output stages. It features V_CEO = 60 V, I_C = 1 A continuous, V_CE(sat) ≤ 0.5 V at I_C = 500 mA / I_B = 50 mA, h_FE = 40–100 (at I_C = 150 mA), and operates up to T_j = 150 °C in automotive-grade SOT223 package.

For engineers reviewing the BCP5216H6327XTSA1 datasheet, BCP5216H6327XTSA1 pinout, BCP5216H6327XTSA1 application, or BCP5216H6327XTSA1 equivalent, key selection criteria include guaranteed DC current gain at high collector current, low saturation voltage under forced beta conditions, thermal resistance R_thJS ≤ 15 K/W, AEC-Q101 qualification, and complementary NPN pairing with BCP54–BCP56 series.

Technical Context

This PNP transistor operates in linear and saturated switching modes, supporting analog amplification and digital switching in AF power stages. Its design emphasizes low V_CE(sat) and stable h_FE across I_C = 5 mA to 500 mA, with f_T = 125 MHz enabling reliable operation beyond audio bandwidth.

Thermal performance is defined by R_thJS ≤ 15 K/W and P_tot = 2 W at T_S ≤ 120 °C, requiring direct heatsinking via the exposed emitter pad in SOT223. The device meets AEC-Q101 stress testing for automotive underhood environments.

FAQ

Is BCP5216H6327XTSA1 pin-compatible with BCP52-16?

Yes - both share identical SOT223-4 package outline, pin assignment (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector), and mechanical footprint. The "H6327XTSA1" suffix denotes Infineon's standard tape-and-reel packaging and date code format; electrical and thermal behavior are fully identical.

What is the maximum allowable PCB copper area for thermal management?

For operation at full 2 W dissipation, the emitter tab (Pin 3) must be soldered to ≥ 200 mm² of 2-oz copper on an internal layer, with ≥ 4 thermal vias (0.3 mm diameter) connecting to inner ground planes. R_thJS ≤ 15 K/W assumes this layout; smaller areas require derating per the P_tot vs. T_S curve in the datasheet.

Can this transistor replace BC857 in a 5 V logic interface?

No - BC857 is an SOT-23 PNP with I_C = 100 mA and V_CEO = 45 V. BCP5216H6327XTSA1 has higher voltage/current ratings but requires larger board space and different base drive due to its 1 A capability. It is over-specified and mechanically incompatible for pure logic-level translation.

Does the dual-collector configuration require external connection between Pins 2 and 4?

No - Pins 2 and 4 are internally shorted to the same collector node inside the die. They may be used independently for routing flexibility or paralleled on PCB to reduce trace inductance and improve current sharing, but no external jumper is needed or recommended.
