Product details

Overview

BCP5116H6327XTSA1 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 45 V V_CEO, 1 A continuous collector current, 0.5 V typical V_CE(sat) at I_C = 500 mA / I_B = 50 mA, h_FE of 100–250 (at I_C = 150 mA), and SOT223 package with four terminals (B-C-E-C). It is RoHS-compliant and AEC-Q101 qualified for automotive-grade reliability.

For engineers reviewing the BCP5116H6327XTSA1 datasheet, BCP5116H6327XTSA1 pinout, BCP5116H6327XTSA1 application, or BCP5116H6327XTSA1 equivalent, key selection criteria include its low saturation voltage in high-current switching, DC gain stability across 5–500 mA, thermal resistance ≤15 K/W (junction-to-soldering point), and complementary NPN pairing with BCP54–BCP56 series for push-pull designs.

Technical Context

This PNP transistor operates in active, saturation, and cutoff regions with defined breakdown limits: V_CEO = 45 V, V_CBO = 45 V, and V_EBO = 5 V. Its f_T = 125 MHz at I_C = 50 mA enables use in medium-speed switching and AF amplification up to ~10 MHz small-signal bandwidth.

Thermal design is supported by R_thJS ≤15 K/W and P_tot = 2 W at T_S ≤120°C. Pulse operation allows peak power up to 2.4× DC rating for t_p ≤10 ms with duty cycle <2%, per pulse test conditions (t < 300 µs, D < 2%).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration
I_C (continuous)	1 A - Continuous DC collector current handling capacity under T_S ≤120°C, suitable for driver-stage loads
V_CE(sat)	0.5 V max at I_C = 500 mA / I_B = 50 mA - Low conduction loss enabling efficient switching in 5–12 V rail systems
h_FE	100–250 at I_C = 150 mA - Stable DC current gain supporting predictable base drive sizing for linear and saturated operation
f_T	125 MHz at I_C = 50 mA / V_CE = 10 V - Enables reliable small-signal amplification up to mid-MHz range
R_thJS	≤15 K/W - Thermal resistance from junction to soldering point, critical for heatsink-less PCB thermal management
P_tot	2 W at T_S = 120°C - Total dissipation limit defining maximum steady-state power handling on standard FR4

Pinout & Package

SOT223 package with 4-terminal configuration: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (dual-collector tab for enhanced thermal and current capability).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Current-controlled input terminal; requires ~50 mA drive for full saturation at 500 mA load
Pin 2	Collector	Main high-side current path; electrically tied to Pin 4 for parallel current sharing and thermal spreading
Pin 3	Emitter	Reference node for biasing; connected to system ground or positive rail depending on topology
Pin 4	Collector (redundant)	Second collector connection to internal die metal; improves thermal conductivity and reduces effective R_DS(on)-like resistance

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including engine control modules and body electronics requiring extended temperature and reliability compliance
Dual-collector SOT223	Enables higher current density and lower thermal resistance than standard 3-pin SOT223, supporting 1 A continuous without external heatsink
Low V_CE(sat)	0.5 V max ensures <250 mW conduction loss at 500 mA, reducing thermal stress in compact PCB layouts
Complementary NPN pairing	Direct match with BCP54–BCP56 series for symmetrical push-pull, H-bridge, and Class AB amplifier designs
Pb-free & RoHS compliant	Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C)

Applications

Automotive Door Module Driver

Industrial Relay Interface

Use Scenario: Driving 12 V DC motor and solenoid loads in vehicle door control units with PWM and enable logic.

IC Role / Device Role / Timing Role: High-side PNP switch controlling ground-referenced loads via emitter-follower or common-emitter configuration.

Use Value: 45 V rating withstands load-dump transients; 1 A rating supports dual-window-lift motors; low V_CE(sat) minimizes self-heating during 100% duty-cycle operation.

Use Scenario: Isolating and amplifying microcontroller GPIO signals to energize 24 V industrial relays with coil currents up to 800 mA.

IC Role / Device Role / Timing Role: Medium-power interface transistor providing current gain and voltage level shifting between logic and relay coil.

Use Value: h_FE ≥100 ensures single-stage drive from 3.3 V/5 V MCU pins; dual-collector layout maintains stable gain under thermal cycling.

Audio Power Amplifier Output Stage

DC-DC Converter Pre-regulator

Use Scenario: Complementary push-pull output stage in Class AB audio amplifiers delivering 1–2 W into 8 Ω speakers.

IC Role / Device Role / Timing Role: PNP half of complementary pair (with BCP54) delivering negative half-cycle current with matched gain and thermal tracking.

Use Value: Matched h_FE spread (100–250) and f_T = 125 MHz ensure low crossover distortion and flat frequency response to 20 kHz.

Use Scenario: Linear pre-regulator stage preceding switching regulators in noise-sensitive analog subsystems (e.g., sensor signal chains).

IC Role / Device Role / Timing Role: Adjustable emitter-follower pass element regulating 12 V input down to 5 V/3.3 V with low ripple and fast transient response.

Use Value: Low V_CE(sat) and high I_C capability allow >500 mA output with <100 mV dropout; R_thJS ≤15 K/W sustains regulation under ambient 85°C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP51-16	Same die, identical electrical specs, but marked "BCP51-16" and shipped in tape-and-reel (1000 pcs/reel); no functional difference	No difference - direct marking variant used interchangeably in production	Select when standard marking format or specific reel quantity required
MMBT5087	Lower V_CEO (30 V), lower I_C (150 mA), SOT23 package, h_FE = 85–375 - not drop-in; requires redesign for current/thermal handling	Only suitable for low-power signal switching (<200 mA), not driver/output stages	Use only for space-constrained signal-level replacement where 45 V/1 A capability is unnecessary

Compared with BCP5116H6327XTSA1, BCP51-16 offers identical performance in a different marking format, while MMBT5087 trades off voltage/current capability for smaller footprint-making it unsuitable for driver-stage replacement without circuit revision.

FAQ

Is BCP5116H6327XTSA1 pin-compatible with BCP51-16?

Yes - both share identical SOT223-4 pinout (Base–Collector–Emitter–Collector), same internal die, and identical electrical specifications. The "H6327XTSA1" suffix denotes Infineon's standard tape-and-reel packaging (1000 pcs/reel, 180 mm reel), while "BCP51-16" is an alternate marking variant with no functional distinction.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is 100 mA (DC), with peak base current up to 200 mA allowed for pulses ≤10 ms. For reliable 1 A collector switching, a base drive of 50 mA is typical to ensure deep saturation; exceeding 100 mA risks bond-wire thermal failure over time.

Can this transistor be used in a linear regulator configuration?

Yes - its 45 V V_CEO, 1 A I_C, and low V_CE(sat) make it suitable as a pass transistor in adjustable linear regulators. However, thermal design must account for P_tot = 2 W at T_S = 120°C; derating is required above 85°C ambient, and the dual-collector SOT223 must be soldered to a minimum 100 mm² copper pour for safe operation.

Does BCP5116H6327XTSA1 support pulsed operation beyond its DC ratings?

Yes - per datasheet pulse test conditions (t < 300 µs, duty cycle <2%), it supports peak collector current up to 1.5 A and peak power up to 2.4× DC rating. This enables short-duration surge handling in motor startup or relay pull-in, provided average power remains within 2 W and junction temperature stays below 150°C.
