Infineon Technologies BCX5216E6433HTMA1

Overview

BCX5216E6433HTMA1 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 collector current, V_CE(sat) ≤ 0.5 V at I_C = 500 mA / I_B = 50 mA, h_FE = 100–250 (at I_C = 150 mA), and SOT-89 surface-mount package. It is used in low-voltage linear amplifier and switching applications requiring high current gain and low saturation voltage.

For engineers reviewing the BCX5216E6433HTMA1 datasheet, BCX5216E6433HTMA1 pinout, BCX5216E6433HTMA1 application, or BCX5216E6433HTMA1 equivalent, key selection criteria include DC current gain consistency across I_C = 5–500 mA, thermal resistance R_thJS ≤ 15 K/W, complementary NPN pairing with BCX54–BCX56 series, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP BJT operates in linear amplification and saturated switching modes, with guaranteed h_FE ≥ 100 at I_C = 150 mA and ≥ 25 at I_C = 500 mA. Its V_CE(sat) ≤ 0.5 V enables efficient power stage operation under moderate load conditions.

The device supports pulsed operation up to I_CM = 1.5 A (t_p ≤ 10 ms) and maintains stable cutoff characteristics with I_CBO ≤ 0.1 µA at V_CB = 30 V and T_A = 25 °C, rising to ≤ 20 µA at 150 °C - critical for thermally demanding environments.

FAQ

Is BCX5216E6433HTMA1 pin-compatible with BCX52-16?

Yes - both share identical SOT-89 package outline, pin 1 (emitter), pin 2 (collector/heatsink), and pin 3 (base) assignment per Infineon's package drawing. Electrical specifications, AEC-Q101 qualification, and thermal ratings are fully aligned; only tape-and-reel marking and reel size differ.

What is the maximum allowable junction temperature during continuous operation?

The absolute maximum junction temperature T_j is 150 °C. Continuous operation at this limit requires strict thermal design: PCB copper area ≥ 250 mm² under pin 2, ambient temperature ≤ 70 °C, and airflow ≥ 1 m/s to maintain T_j ≤ 150 °C at full 2 W dissipation.

Can BCX5216E6433HTMA1 be used in linear regulator pass transistor applications?

Yes - its V_CE(sat) ≤ 0.5 V at I_C = 500 mA and h_FE ≥ 100 support stable emitter-follower configurations. However, thermal derating is required above 70 °C ambient; maximum safe I_C drops to 750 mA at T_A = 100 °C with 250 mm² copper pour.

Does this part have built-in ESD protection?

No - BCX5216E6433HTMA1 has no integrated ESD protection diodes. External 1 kΩ base resistor and 10 nF capacitor to ground are recommended for handling >2 kV HBM events during assembly, per Infineon Application Note AN077.
