Product details

Overview

BCX5216E6327HTSA1 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 BCX5216E6327HTSA1 datasheet, BCX5216E6327HTSA1 pinout, BCX5216E6327HTSA1 application, or BCX5216E6327HTSA1 equivalent, key selection criteria include DC current gain consistency at high collector current, low saturation voltage under 500 mA load, thermal resistance (R_thJS ≤ 15 K/W), and complementary NPN pairing with BCX54–BCX56 series.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions for analog amplification and digital switching. Its design supports stable DC biasing with h_FE specified across I_C = 5 mA to 500 mA and V_CE = 2 V, and maintains low V_CE(sat) even at elevated junction temperatures up to 150 °C.

The device uses epitaxial planar technology with gold-doped base region to achieve high f_T = 125 MHz (typ.) and fast switching response. Its SOT-89 package provides robust thermal dissipation (P_tot = 2 W at T_S ≤ 120 °C) and mechanical stability for board-level power handling in compact layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration
I_C (cont.)	1 A - Continuous collector current rating defining usable linear/saturation range
V_CE(sat)	≤ 0.5 V @ I_C = 500 mA, I_B = 50 mA - Low on-state loss enabling efficient switching in power stages
h_FE	100–250 @ I_C = 150 mA, V_CE = 2 V - Predictable current amplification for bias network design
f_T	125 MHz (typ.) @ I_C = 50 mA, V_CE = 10 V - Enables stable operation up to mid-VHF frequencies in AF/RF driver roles
R_thJS	≤ 15 K/W - Thermal resistance from junction to solder point, critical for thermal management in PCB copper pour designs
P_tot	2 W @ T_S ≤ 120 °C - Total power dissipation limit dictating heatsinking requirements

Pinout & Package

SOT-89 package: 3-pin surface-mount plastic case with exposed emitter pad for thermal conduction and mechanical anchoring. Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter (standard BCX series pinout per Infineon outline drawing).

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Current-controlled input terminal	Receives base drive current to regulate collector-emitter conduction; requires current-limiting resistor in most linear applications
2 (Collector)	High-side current sink node	Connected to positive supply rail in common-emitter switch configurations; carries full load current
3 (Emitter)	Reference and current return path	Typically tied to ground or load return; serves as thermal interface via exposed metal tab in SOT-89

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock
Low V_CE(sat) at high I_C	Ensures <100 mW conduction loss at 500 mA, reducing thermal stress in Class-AB output stages
Complementary NPN pairing	Direct match with BCX54–BCX56 series enables push-pull amplifier and H-bridge designs without gain mismatch
RoHS-compliant packaging	Lead-free SOT-89 construction meets EU Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles

Applications

Automotive Interior Lighting Control

Industrial 24V Relay Driver

Use Scenario: Driving LED strings or incandescent lamps in dashboard backlighting and ambient lighting modules.

IC Role / Device Role / Timing Role: PNP switch controlling current flow from 12V/24V rail to lamp cathode, operated by microcontroller GPIO.

Use Value: Low V_CE(sat) minimizes heat generation in confined enclosures; AEC-Q101 rating ensures reliability over 15-year vehicle lifetime.

Use Scenario: Activating electromechanical relays in PLC I/O modules and motor control panels.

IC Role / Device Role / Timing Role: High-current interface between logic-level controller and relay coil (typically 100–500 mA).

Use Value: 1 A I_C rating accommodates relay inrush currents; robust SOA prevents secondary breakdown during coil de-energization.

Audio Power Amplifier Output Stage

DC-DC Converter Pre-regulator

Use Scenario: Complementary emitter-follower output stage in 1–3 W audio amplifiers for automotive head units.

IC Role / Device Role / Timing Role: PNP half of Class-AB push-pull pair delivering low-impedance drive to speaker load.

Use Value: h_FE ≥ 100 at 150 mA ensures stable bias current setting; f_T > 100 MHz preserves signal fidelity up to 20 kHz.

Use Scenario: Linear pre-regulator stage ahead of buck converter ICs to reduce input ripple and improve PSRR.

IC Role / Device Role / Timing Role: Pass transistor operating in active region to drop excess input voltage before switching stage.

Use Value: 2 W P_tot and R_thJS ≤ 15 K/W enable continuous operation at 500 mA with minimal heatsink area.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCX52-16 (Infineon)	Same die, identical electrical specs, but marked "BCX52-16" instead of "BCX5216E6327HTSA1"; same SOT-89 package and reel packaging	No functional difference; used interchangeably in production where marking format is not controlled	Select when standard marking compliance (e.g., JEDEC TO-252 vs. SOT-89 variant) is not required
MJD2955G (ON Semiconductor)	Higher V_CEO = 80 V, lower h_FE min = 20, TO-252 package with larger thermal mass (R_thJA ≈ 40 K/W vs. 15 K/W junction-to-solder)	Better for higher-voltage industrial loads but less suitable for space-constrained automotive PCBs	Choose when system voltage exceeds 60 V or when TO-252 mounting is preferred for manual assembly

Compared with BCX52-16, this part offers identical performance in identical packaging; compared with MJD2955G, it trades off voltage headroom for superior thermal efficiency and smaller footprint in automotive-grade SMT designs.

FAQ

Is BCX5216E6327HTSA1 pin-compatible with BCX52-16?

Yes - both share identical SOT-89 pinout (Base–Collector–Emitter), identical die characteristics, and identical thermal and electrical specifications. The only distinction is marking format and tape-and-reel coding; no layout or schematic changes are needed for substitution.

What is the maximum allowable junction temperature during continuous operation?

The absolute maximum junction temperature is 150 °C, as defined in the Infineon datasheet. Operation must remain within the Safe Operating Area (SOA) curve, especially under simultaneous high V_CE and I_C; derating is required above T_S = 120 °C to maintain P_tot ≤ 2 W.

Does this transistor support pulsed operation beyond its DC ratings?

Yes - pulse testing confirms I_CM = 1.5 A for t_p ≤ 10 ms with duty cycle D ≤ 2%. Permissible peak power scales inversely with pulse width per the R_thJS vs. t_p curve; sustained pulses require verification against the SOA diagram in Application Note AN077.

Can BCX5216E6327HTSA1 be used in complementary symmetry amplifier circuits?

Yes - it is explicitly designed as the PNP complement to BCX54–BCX56 NPN transistors. Matching h_FE ranges, V_CE(sat), and thermal coefficients enable balanced Class-AB operation with minimized crossover distortion in audio and precision analog output stages.
