Product details

Overview

BCV27E6395HTMA1 from Infineon Technologies is an NPN silicon Darlington transistor optimized for general-purpose audio-frequency switching and amplification, featuring 30 V V_CEO, 500 mA I_C, minimum h_FE of 4000 at 100 µA, and SOT23 package. It delivers high current gain with low saturation voltage (V_CEsat ≤ 1 V at I_C = 100 mA, I_B = 0.1 mA) in automotive-grade AEC-Q101-qualified applications.

For engineers reviewing the BCV27E6395HTMA1 datasheet, BCV27E6395HTMA1 pinout, BCV27E6395HTMA1 application, or BCV27E6395HTMA1 equivalent, this part serves as a high-gain, low-base-drive discrete switch in power management stages, sensor interface buffers, and relay drivers where compact size and thermal robustness are critical.

Technical Context

The BCV27E6395HTMA1 implements a monolithic Darlington pair structure with integrated base-emitter resistor network absent - requiring external base drive control. Its dual-transistor configuration enables ultra-high DC current gain (h_FE up to 20,000) while maintaining V_CEsat ≤ 1 V and f_T = 170 MHz at I_C = 50 mA, V_CE = 5 V.

Rated for operation from −65 °C to +150 °C junction temperature and qualified per AEC-Q101, it supports stable performance under pulsed loads (t_p ≤ 10 ms, I_CM = 800 mA) and exhibits C_cb = 3 pF at V_CB = 10 V, enabling use in moderate-speed switching circuits without excessive Miller effect.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in low-voltage switching rails.
I_C	500 mA continuous - Sustained collector current capability; supports driving small relays or LED arrays directly.
h_FE (min)	4000 at I_C = 100 µA - Enables microampere-level base drive for efficient low-power control interfaces.
V_CEsat	≤ 1 V at I_C = 100 mA, I_B = 0.1 mA - Minimizes conduction loss and self-heating in linear or saturated switching modes.
f_T	170 MHz - Supports signal amplification and switching up to mid-VHF band; suitable for AF and low-speed digital edge shaping.
C_cb	3 pF at V_CB = 10 V - Limits capacitive coupling between collector and base; reduces unintended turn-on in fast-switching layouts.
P_tot	360 mW at T_S ≤ 74 °C - Defines maximum dissipation under defined board thermal conditions; requires PCB copper area for heatsinking.

Pinout & Package

SOT23 plastic surface-mount package (3-pin, standard footprint), lead-free and RoHS compliant. Dimensions per Infineon outline drawing: 2.9 mm × 1.3 mm × 1.0 mm, 0.95 mm pitch, 0.25 mm lead width.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base	Input control terminal; requires current-limited drive due to Darlington's high h_FE; no internal base resistor.
2 (E)	Emitter	Common emitter node; connected to ground or low-side return path; carries full load current.
3 (C)	Collector	Output terminal; connects to load supply rail; must be decoupled when switching inductive loads.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive electronics per stress test requirements including HTOL, TC, HTRB - ensures reliability in engine bay and chassis modules.
High h_FE (up to 20,000)	Reduces required base drive current by >10× versus single bipolar transistors - simplifies microcontroller GPIO interfacing.
Low V_CEsat (≤ 1 V)	Minimizes power loss and thermal rise in high-duty-cycle switching; improves efficiency in battery-powered sensor nodes.
Thermal resistance R_thJS ≤ 210 K/W	Enables predictable junction temperature estimation using solder-point temperature - supports thermal-aware layout design.
Complementary PNP pairing (BCV26)	Allows matched push-pull output stages with symmetrical gain and saturation characteristics in analog driver circuits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN Darlington transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCV27,115 (Nexperia)	Same electrical specs (V_CEO = 30 V, h_FE min = 4000), but not AEC-Q101 qualified; R_thJS = 250 K/W vs 210 K/W.	Limited to commercial/industrial use; unsuitable for automotive under-hood deployment.	Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs thermal margin.
MMBT5401LT1G (ON Semiconductor)	PNP complement (not NPN); V_CEO = 150 V, h_FE = 60–250 - lower gain, higher voltage rating, different polarity.	Used only in complementary pairs; cannot substitute directly in NPN-only circuits.	Choose only for PNP-side matching in push-pull designs; not a functional replacement for BCV27E6395HTMA1.

Compared with BCV27,115, BCV27E6395HTMA1 offers tighter thermal resistance and automotive qualification; versus MMBT5401LT1G, it provides NPN polarity, Darlington gain architecture, and 30 V rating - making it uniquely suited for low-voltage, high-gain switching where reliability and compactness are prioritized.

FAQ

Is BCV27E6395HTMA1 pin-compatible with BCV27,115?

Yes - both use identical SOT23 package with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. Mechanical footprint, solder pad layout, and terminal assignment match exactly per JEDEC MO-203-AB and Infineon's SOT23 outline drawings.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is 100 mA (I_B), with peak base current limited to 200 mA for pulses ≤10 ms. Exceeding 100 mA continuously risks thermal runaway due to power dissipation in the base-emitter junction.

Can BCV27E6395HTMA1 replace BCV47 in a circuit?

No - BCV47 has V_CEO = 60 V and V_CBO = 80 V, whereas BCV27E6395HTMA1 is rated for 30 V and 40 V respectively. Substitution is unsafe in circuits operating above 30 V collector-emitter potential.

Does BCV27E6395HTMA1 include an integrated base-emitter resistor?

No - it is a bare Darlington transistor without any internal biasing resistors. External base current must be supplied through a series resistor or active driver; no pull-down or pull-up networks are integrated.
