Infineon Technologies BCX5216H6327XTSA1

Overview

BCX5216H6327XTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. 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 = 100–250 (at I_C = 150 mA), and SOT-89 surface-mount package. It is RoHS-compliant and AEC-Q101 qualified for automotive-grade reliability.

For engineers reviewing the BCX5216H6327XTSA1 datasheet, BCX5216H6327XTSA1 pinout, BCX5216H6327XTSA1 application, or BCX5216H6327XTSA1 equivalent, key selection criteria include its PNP polarity, 60 V V_CEO, 1 A I_C, low saturation voltage, and thermal resistance R_thJS ≤ 15 K/W - critical for compact power amplification and load switching designs.

Technical Context

This transistor operates as a medium-power PNP switch or linear amplifier with DC current gain h_FE specified across three test conditions: 25–100 at I_C = 5 mA, 40–160 at I_C = 150 mA, and 100–250 at I_C = 150 mA for BCX52-16 variants. Its f_T = 125 MHz enables stable operation up to mid-VHF range in tuned circuits.

Thermal design is supported by R_thJS ≤ 15 K/W and a maximum junction temperature of 150 °C. The device sustains pulsed collector currents up to 1.5 A (t_p ≤ 10 ms) and exhibits low leakage: I_CBO ≤ 0.1 µA at 30 V and ≤ 20 µA at 150 °C.

FAQ

Is BCX5216H6327XTSA1 pin-compatible with BCX52-16?

Yes - both share identical SOT-89 pinout (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter) and mechanical footprint. The "H6327XTSA1" suffix denotes Infineon's standard 1,000-piece tape-and-reel packaging per DIN EN 60286-3, while BCX52-16 may appear in alternate reels or bulk formats. Electrical and thermal specifications are fully identical.

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is 100 mA, per the "Maximum Ratings" table. For reliable long-term operation at I_C = 1 A, design base drive to deliver 50–80 mA - sufficient for h_FE-based saturation while maintaining margin against thermal runaway and bond-wire stress.

Can BCX5216H6327XTSA1 be used in linear regulator pass-transistor applications?

Yes - its V_CEO = 60 V, P_tot = 2 W, and R_thJS ≤ 15 K/W support use as a series pass element in adjustable linear regulators up to ~1.2 A output. Ensure V_IN − V_OUT × I_OUT remains within SOA limits and implement adequate heatsinking or current limiting to prevent secondary breakdown.

Does this part meet automotive qualification standards beyond AEC-Q101?

BCX5216H6327XTSA1 is explicitly qualified to AEC-Q101 for stress testing (HTOL, TC, HAST, etc.) and is manufactured in Infineon's certified automotive production lines. It does not carry full AEC-Q200 (passive components) or ISO/TS 16949 certification itself - those apply to system-level validation. Component-level compliance is defined by AEC-Q101.
