Product details

Overview

BCX5116E6327HTSA1 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 = 45 V, I_C = 1 A continuous, h_FE = 100–250 (at I_C = 150 mA), V_CE(sat) ≤ 0.5 V (at I_C = 500 mA, I_B = 50 mA), and SOT-89 surface-mount package. It is RoHS-compliant and AEC-Q101 qualified for automotive-grade reliability.

For engineers reviewing the BCX5116E6327HTSA1 datasheet, BCX5116E6327HTSA1 pinout, BCX5116E6327HTSA1 application, or BCX5116E6327HTSA1 equivalent, key selection criteria include DC current gain consistency at medium collector currents, low saturation voltage under high drive conditions, thermal resistance (R_thJS ≤ 15 K/W), and complementary NPN pairing with BCX54–BCX56 series in power amplifier designs.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined breakdown limits: V_(BR)CEO = 45 V, V_(BR)CBO = 45 V, and V_(BR)EBO = 5 V. Its f_T = 125 MHz (at I_C = 50 mA, V_CE = 10 V) supports stable operation up to mid-VHF frequencies in small-signal amplification.

Thermal design is enabled by R_thJS ≤ 15 K/W and P_tot = 2 W at T_S ≤ 120 °C, with pulse derating curves validated per JEDEC JESD51 standards. The device meets AEC-Q101 stress test requirements for temperature cycling, HTRB, and ESD (HBM ≥ 2 kV).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum safe collector-emitter voltage before avalanche in common-emitter configuration
I_C (continuous)	1 A - Continuous collector current rating usable in linear regulators or Class AB output stages
h_FE	100–250 - DC current gain range at I_C = 150 mA, V_CE = 2 V, enabling predictable base drive sizing
V_CE(sat)	≤ 0.5 V - Low saturation voltage at I_C = 500 mA / I_B = 50 mA, minimizing conduction loss in switch-mode circuits
f_T	125 MHz - Transition frequency confirming suitability for AF-to-low-RF amplification without instability
R_thJS	≤ 15 K/W - Junction-to-solder-point thermal resistance supporting PCB copper pour design for thermal management
P_tot	2 W - Total power dissipation limit at case temperature ≤ 120 °C, defining maximum steady-state thermal load

Pinout & Package

The BCX5116E6327HTSA1 is housed in a plastic SOT-89 surface-mount package with standard lead frame geometry, 3-pin configuration, and tape-and-reel packaging (1000 pcs/reel, ø180 mm).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	E	Current exit path; connected to ground or low-side reference in common-emitter topology
2 (Collector)	C	Current entry path; tied to load supply rail in high-side switch or amplifier output stage
3 (Base)	B	Control terminal; requires current-limited drive (I_B ≤ 100 mA) to achieve specified h_FE and V_CE(sat)

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive electronics per stress test requirements including HTGB, TC, and AC/DC life testing
Low V_CE(sat)	≤ 0.5 V at I_C/I_B = 10 ensures <100 mW conduction loss in 500 mA switching applications
Complementary pairing	Matched performance with BCX54–BCX56 NPN types enables push-pull amplifier and H-bridge driver implementation
Pb-free & RoHS compliant	Meets EU Directive 2011/65/EU; no exemption required for lead content in solderable terminations
High f_T	125 MHz allows stable small-signal amplification up to 20 MHz with >10 dB gain margin

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCX5116TA	Same die, identical electrical specs; differs only in tape-and-reel packaging (3000 pcs vs. 1000 pcs) and marking format	No functional difference; suitable for same PCB layouts and thermal designs	Select when higher reel quantity reduces assembly line changeover frequency
MMBT5087LT1G	Lower V_CEO = 30 V, lower I_C = 0.1 A, SOT-23 package - not interchangeable due to current and voltage derating	Limited to low-power signal switching; unsuitable for 1 A load applications	Only consider for space-constrained, sub-100 mA bias or logic-level translation roles

Compared with BCX5116TA, BCX5116E6327HTSA1 offers identical performance in a smaller reel size optimized for prototyping and low-volume production; MMBT5087LT1G lacks the voltage headroom and current capability needed for automotive output stages, making it non-substitutable in primary applications.

FAQ

Is BCX5116E6327HTSA1 pin-compatible with BCX52 or BCX53 variants?

No. While all share the SOT-89 package and identical pinout (E-C-B), BCX5116E6327HTSA1 has V_CEO = 45 V and h_FE = 100–250, whereas BCX52-16 specifies V_CEO = 60 V and BCX53-16 specifies V_CEO = 80 V. Substitution requires verification of voltage margin and gain stability in the target circuit.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is I_B = 100 mA (DC), with peak pulsed base current I_BM = 200 mA for t_p ≤ 10 ms. For reliable long-term operation, design base drive to maintain I_B ≤ 50 mA at I_C = 500 mA to ensure V_CE(sat) remains within spec and avoid localized heating at the base contact.

Does this transistor support operation at 150 °C junction temperature?

Yes - T_j = 150 °C is the absolute maximum rated junction temperature. However, electrical characteristics (e.g., h_FE, V_CE(sat)) are only guaranteed at T_A = 25 °C. At elevated temperatures, h_FE increases while V_CE(sat) rises slightly; derating of P_tot per R_thJA curve is mandatory above 120 °C case temperature.

Can BCX5116E6327HTSA1 be used as a direct replacement for BCX51-16 in existing designs?

Yes - BCX5116E6327HTSA1 is the industrial-grade, tape-and-reel packaged variant of BCX51-16 with identical electrical specifications, thermal ratings, and SOT-89 mechanical footprint. The "E6327HTSA1" suffix denotes Infineon's standard packaging code for 1000-piece reels with humidity-sensitive level 1 handling.
