Product details

Overview

BCP5616E6327HTSA1 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It features 80 V collector-emitter breakdown voltage (V_(BR)CEO), 1 A continuous collector current (I_C), 0.5 V collector-emitter saturation voltage (V_CE(sat)) at I_C = 500 mA / I_B = 50 mA, and DC current gain (h_FE) of 100–250 at I_C = 150 mA. It is used in automotive amplifier bias networks and industrial power supply switch drivers.

For engineers reviewing the BCP5616E6327HTSA1 datasheet, BCP5616E6327HTSA1 pinout, BCP5616E6327HTSA1 application, or BCP5616E6327HTSA1 equivalent, key selection criteria include V_CEO rating, saturation voltage under high-current drive, thermal resistance (R_thJS ≤ 15 K/W), complementary PNP pairing (BCP53 series), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This transistor operates as a medium-power NPN switch or linear amplifier with fixed-emitter configuration. Its 80 V V_(BR)CEO and 100 V V_(BR)CBO ratings support operation in 48 V and 60 V rail systems, while its 2 W total power dissipation (at T_S ≤ 120°C) enables use with moderate heatsinking.

The device exhibits h_FE = 100–250 at I_C = 150 mA and V_CE = 2 V, and maintains V_CE(sat) ≤ 0.5 V up to I_C = 500 mA, enabling efficient low-loss switching in Class AB output stages and relay drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)CEO	80 V - supports 48 V/60 V system rails with margin against transients
I_C (continuous)	1 A - suitable for driving relays, small solenoids, and pre-driver stages
V_CE(sat)	≤ 0.5 V at I_C = 500 mA / I_B = 50 mA - minimizes conduction loss in saturated-switching mode
h_FE	100–250 at I_C = 150 mA - ensures stable base drive design across production lot variation
R_thJS	≤ 15 K/W - enables thermal management with minimal PCB copper area or external heatsink
f_T	100 MHz - sufficient for audio-band amplification and PWM frequencies up to ~10 MHz
T_j max	150 °C - allows operation in under-hood automotive environments with derating

Pinout & Package

SOT-223 package with 4-pin configuration: Pin 1 = Base (B), Pin 2 = Collector (C), Pin 3 = Emitter (E), Pin 4 = Collector (C) - dual-collector tab improves thermal and current handling.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Control input; requires current-limited drive (max I_B = 100 mA DC) to avoid secondary breakdown
Pin 2	Collector	Main current output node; electrically tied to Pin 4 and exposed metal tab for thermal path
Pin 3	Emitter	Reference terminal; must be connected directly to ground or low-impedance return path
Pin 4	Collector	Secondary collector connection; shares same node as Pin 2 to reduce bondwire inductance and improve thermal spreading

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive temperature cycling, humidity, and mechanical stress per JESD22 standards
Pb-free (RoHS compliant)	Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C)
Complementary PNP pairing	Matches BCP53-16 for push-pull output stages without gain mismatch
Low V_CE(sat) at high I_C	Ensures <1.5 W conduction loss at 500 mA, reducing thermal load in compact enclosures
High f_T with stable h_FE	Enables wideband audio amplification (20 Hz–20 kHz) with <0.1% THD+N at 1 W into 8 Ω

Applications

Automotive Audio Amplifier Output Stage

Industrial 48 V DC-DC Converter Gate Driver

Use Scenario: Final output stage in Class AB car radio amplifiers delivering 10–20 W into 4 Ω loads.

IC Role / Device Role / Timing Role: Saturated switch translating logic-level signals to 10–20 mA gate drive pulses.

Use Value: 100–250 h_FE ensures reliable turn-on with minimal MCU GPIO current, reducing firmware overhead.

Programmable Logic Controller (PLC) Output Module

LED String Power Switch for Smart Lighting

Use Scenario: Solid-state relay replacement in 24 V/48 V PLC digital output cards driving solenoid valves and indicators.

IC Role / Device Role / Timing Role: Medium-power switching transistor with integrated base resistor network (external) for current limiting.

IC Role / Device Role / Timing Role: Linear pass element in analog dimming circuits with PWM-synchronized bias control.

Use Value: R_thJS ≤ 15 K/W allows direct mounting on aluminum extrusion, eliminating discrete heatsinks in slim-profile fixtures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP56-16T (Nexperia)	Same V_CEO, h_FE = 100–200, R_thJS = 17 K/W, no AEC-Q101 qualification	Not approved for automotive under-hood use; suitable for industrial controls only	Select when AEC-Q101 is not required and cost sensitivity outweighs thermal margin
MJD127G (ON Semiconductor)	Higher V_CEO = 100 V, lower h_FE = 30–120, TO-252 package, R_thJS = 20 K/W	Requires larger PCB footprint; better for 72 V telecom systems but less efficient at 48 V	Select when higher voltage headroom is needed and thermal performance is secondary

Compared with BCP5616E6327HTSA1, BCP56-16T trades automotive qualification for lower unit cost, while MJD127G offers extended voltage range at the expense of gain consistency and thermal efficiency-making the Infineon part optimal for space-constrained, thermally demanding automotive and industrial 48 V applications.

FAQ

Is BCP5616E6327HTSA1 pin-compatible with BCP54 or BCP55 variants?

Yes - all BCP54/55/56 variants share identical SOT-223 pinout (Pin 1 = B, Pin 2 = C, Pin 3 = E, Pin 4 = C) and mechanical footprint. However, V_CEO, V_CBO, and h_FE differ across types; substituting without circuit review may cause overvoltage failure or gain mismatch.

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is 100 mA per datasheet. For reliable long-term operation, limit I_B to ≤ 50 mA with adequate PCB copper pour on Pin 1 to prevent localized heating and h_FE degradation above 125°C junction temperature.

Does this transistor require a base resistor when driven by a microcontroller GPIO?

Yes - a series base resistor is mandatory. With typical V_BE(ON) ≈ 0.9 V and GPIO output of 3.3 V or 5 V, a 1–2.2 kΩ resistor limits I_B to 1–2.5 mA, ensuring safe h_FE-driven saturation at I_C ≤ 250 mA without exceeding GPIO current limits.

Can BCP5616E6327HTSA1 be used in parallel configurations for higher current?

No - due to h_FE variation and thermal runaway risk, parallel operation is not recommended. For >1 A loads, use a single higher-rated device (e.g., BUX87) or implement active current balancing with emitter resistors and matched layout.
