Product details

Overview

BCV47E6327HTSA1 from Infineon Technologies is an NPN silicon Darlington transistor in SOT23 package, rated for 60 V V_CEO, 500 mA continuous collector current, and minimum DC current gain (h_FE) of 2000 at IC = 10 mA / V_CE = 5 V. It serves as a high-gain switching or amplification element in low-power audio and signal interface stages.

For engineers reviewing the BCV47E6327HTSA1 datasheet, BCV47E6327HTSA1 pinout, BCV47E6327HTSA1 application, or BCV47E6327HTSA1 equivalent, key selection criteria include its Darlington configuration enabling microampere-level base drive, V_CEO = 60 V rating for moderate-voltage load control, and SOT23 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a monolithic two-stage NPN Darlington pair with integrated emitter resistor, delivering high current gain while maintaining single-transistor pinout simplicity. Its structure supports low-base-drive switching in relay drivers and sensor interface amplifiers where input current must remain below 100 µA.

Thermal resistance R_thJS ≤ 210 K/W and T_j = 150 °C maximum junction temperature enable operation under sustained 360 mW dissipation at board temperatures up to 74 °C, validated per AEC-Q101 for automotive-grade reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Supports switching of 48 V nominal bus loads with safety margin
I_C (continuous)	500 mA - Drives medium-current loads such as small relays or LED arrays
h_FE (min)	2000 @ I_C = 10 mA - Enables <10 µA base current for 10 mA collector output
V_CE(sat)	1 V max @ I_C = 100 mA, I_B = 0.1 mA - Limits conduction loss to ≤100 mW at rated current
f_T	170 MHz typ - Sufficient for audio-band amplification and low-speed digital switching
C_cb	3 pF max @ V_CB = 10 V - Minimizes Miller effect in high-gain amplifier configurations
P_tot	360 mW @ T_S ≤ 74 °C - Requires thermal pad or copper pour for full-power operation

Pinout & Package

SOT23-3 plastic surface-mount package with standard lead pitch (0.95 mm), body dimensions 2.9 × 1.3 × 1.0 mm, and moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.

2 (Base)	Control input for both transistors	Accepts microampere-level drive; internal resistor reduces external bias complexity
3 (Collector)	Output terminal sourcing load current	Switches positive rail to load; requires external pull-up or supply connection

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCV47,115 (Nexperia)	Same V_CEO = 60 V, h_FE min = 2000, but SOT23 marking differs and R_thJA is 350 K/W vs 210 K/W	Lower thermal efficiency limits continuous power to 250 mW at 74 °C ambient	Select when cost sensitivity outweighs thermal margin requirements
MMDT3904-7-F (Diodes Inc.)	Single NPN (not Darlington), V_CEO = 40 V, h_FE min = 100 - requires higher base drive and offers lower voltage capability	Not suitable for 48 V systems or sub-10 µA drive scenarios	Choose only for non-Darlington designs where gain >1000 is unnecessary

Compared with BCV47E6327HTSA1, BCV47,115 trades thermal performance for broader distribution availability, while MMDT3904-7-F sacrifices Darlington gain and voltage rating for higher f_T (300 MHz) in RF-coupled preamp roles.

FAQ

What is the maximum safe operating temperature for BCV47E6327HTSA1?

The junction temperature must not exceed 150 °C. With R_thJS ≤ 210 K/W and P_tot = 360 mW, the soldering point temperature must stay ≤ 74 °C. Board-level thermal design-such as copper pour under the SOT23 pad-is required to maintain this limit during continuous operation.

Can BCV47E6327HTSA1 replace BCV27 in existing designs?

No-BCV47 has V_CEO = 60 V and V_CBO = 80 V versus BCV27's 30 V and 40 V ratings. Swapping without circuit review risks overvoltage failure in BCV27-designed 30 V systems. The devices share pinout and package but differ electrically in breakdown and gain profiles.

Does BCV47E6327HTSA1 include an internal base-emitter resistor?

No-the BCV47E6327HTSA1 is a bare Darlington pair without integrated bias resistors. External base resistors must be used to set operating point; typical designs use 10–100 kΩ pull-up/pull-down networks depending on drive source impedance and required switching speed.

Is BCV47E6327HTSA1 suitable for linear amplifier applications?

Yes-its h_FE stability across I_C = 100 µA to 500 mA and V_CE(sat) < 1 V support Class-A and AB audio preamplifier stages. However, thermal derating is essential above 100 mW dissipation; use with emitter degeneration and proper heatsinking for sustained linearity.
