Product details

Overview

BCP5316H6433XTMA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio frequency driver and output stages. It features 80 V V_CEO, 1 A continuous collector current, 0.5 V V_CE(sat) at I_C = 500 mA/I_B = 50 mA, h_FE = 100–250 (I_C = 150–500 mA), and SOT223 package. It is used in automotive amplifier output stages requiring high-current switching with low saturation loss.

For engineers reviewing the BCP5316H6433XTMA1 datasheet, BCP5316H6433XTMA1 pinout, BCP5316H6433XTMA1 application, or BCP5316H6433XTMA1 equivalent, key selection criteria include V_CEO rating, DC current gain at high I_C, thermal resistance (R_thJS ≤ 15 K/W), complementary NPN pairing (BCP56-16), and AEC-Q101 qualification for automotive use.

Technical Context

This PNP transistor operates in linear and saturated switching modes with guaranteed h_FE ≥ 100 at I_C = 150 mA and ≥ 63 at I_C = 500 mA. Its V_CE(sat) ≤ 0.5 V enables efficient power stage operation under high-current load conditions.

Thermal design is supported by R_thJS ≤ 15 K/W and T_j = 150 °C maximum junction temperature. The device meets AEC-Q101 stress test requirements for automotive electronics reliability, including temperature cycling and HTRB.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - supports rail voltages up to 60 V in Class-AB audio output stages without breakdown risk
I_C (continuous)	1 A - delivers full drive capability for speaker drivers and relay coils in automotive body control modules
V_CE(sat)	≤ 0.5 V @ I_C = 500 mA / I_B = 50 mA - minimizes conduction loss and self-heating in high-duty-cycle switching
h_FE	100–250 @ I_C = 150–500 mA - ensures stable base drive margin across production spread and temperature range
f_T	125 MHz - sufficient for AF amplification up to 20 kHz with ample gain-bandwidth margin
R_thJS	≤ 15 K/W - enables 2 W dissipation with ≤30 K rise from solder point, supporting compact heatsinkless PCB layout
AEC-Q101	Qualified - validated for automotive under-hood applications per stress test requirements (HTOL, TC, HTRB)

Pinout & Package

SOT223 package with 4-pin configuration: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (tab). The exposed collector tab provides low-thermal-resistance path to PCB copper pour.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Current-controlled input terminal; requires 50 mA drive for full 500 mA collector switching
Pin 2	Collector	Main high-current output node; electrically tied to Pin 4 (collector tab) for thermal and current sharing
Pin 3	Emitter	Reference terminal for bias network; connected to supply rail in common-emitter switch configuration
Pin 4	Collector (Tab)	Exposed metal pad soldered to PCB ground plane or heatsink area; carries full collector current and dissipates heat

Key Features

Feature	Design Value
High V_CEO rating	80 V enables use in 48 V automotive systems and industrial 60 V DC rails without derating
Low V_CE(sat)	≤ 0.5 V reduces power loss by >30% vs. legacy PNP transistors at 500 mA load
AEC-Q101 qualification	Validated for automotive under-hood environments including 1000-hour HTOL at 150 °C
Complementary NPN pairing	Direct match with BCP56-16 (V_CEO = 80 V, I_C = 1 A) for push-pull output stages
Pb-free & RoHS compliant	Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C)

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP bipolar transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP53-16TMA1	Same die, identical electrical specs; differs only in tape-and-reel packaging (1000 pcs vs. 4000 pcs per reel)	No functional difference; suitable for same PCB layouts and thermal designs	Select based on volume procurement needs and line-side reel change frequency
MJD2955G	Higher V_CEO (100 V), higher I_C (1.5 A), but larger TO-220 package and no AEC-Q101 qualification	Requires mechanical redesign; not qualified for automotive under-hood use	Use only in industrial non-automotive applications where higher voltage margin justifies larger footprint

Compared with BCP5316H6433XTMA1, BCP53-16TMA1 offers identical performance in smaller-volume reels, while MJD2955G trades AEC-Q101 compliance and SOT223 compactness for higher voltage/current headroom in TO-220 form factor.

FAQ

What is the maximum safe operating temperature for BCP5316H6433XTMA1?

The absolute maximum junction temperature is 150 °C, and storage temperature range is –65 °C to +150 °C. For reliable long-term operation, keep T_j ≤ 135 °C under worst-case ambient and power dissipation conditions. Derate total power dissipation linearly above 120 °C case temperature per the P_tot vs. T_S curve in the datasheet.

Is BCP5316H6433XTMA1 pin-compatible with other SOT223 PNP transistors?

Yes - it uses standard SOT223 pinout: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (tab). This matches industry-standard SOT223 layout and is mechanically and electrically compatible with PCB footprints for BCP53-16, MMBT53, and ZTX951, though electrical parameters differ.

Does this transistor require a base resistor in switching applications?

Yes - a base resistor is required to limit I_B and ensure proper saturation. For 500 mA I_C, minimum I_B = 5 mA (assuming h_FE = 100); using 50 mA I_B ensures deep saturation. With 3.3 V GPIO drive, a 47 Ω resistor delivers ~50 mA while accounting for V_BE(ON) ≈ 0.9 V.

Can BCP5316H6433XTMA1 be used in linear amplifier mode?

Yes - its f_T = 125 MHz and h_FE stability across I_C support linear operation in Class-A or Class-AB audio pre-driver stages. However, thermal management is critical: at 1 W dissipation, R_thJS ≤ 15 K/W requires ≥ 3 cm² 2-oz copper pour to maintain T_j < 125 °C at 70 °C ambient.
