Product details

Overview

BCV47E6393HTSA1 from Infineon Technologies is an NPN silicon Darlington transistor in SOT23 package, rated for 60 V V_CEO, 500 mA I_C, and minimum h_FE of 2000 at 100 µA I_C. It delivers high current gain and low saturation voltage (V_CEsat ≤ 1 V @ 100 mA/0.1 mA), suited for low-power amplifier and switching stages in automotive body electronics.

For engineers reviewing the BCV47E6393HTSA1 datasheet, BCV47E6393HTSA1 pinout, BCV47E6393HTSA1 application, or BCV47E6393HTSA1 equivalent, key selection criteria include V_CEO/V_CBO ratings, h_FE vs. I_C curve, thermal resistance R_thJS ≤ 210 K/W, and AEC-Q101 qualification status for automotive use.

Technical Context

This Darlington pair integrates two NPN transistors in cascade to achieve high DC current gain while maintaining single-package simplicity. Its structure enables stable amplification at microampere base drive levels and supports linear operation up to 100 mA collector current with V_CE = 5 V.

The device operates across −65 °C to +150 °C junction temperature range and features V_BREBO = 10 V, C_cb = 3 pF @ 10 V, and f_T = 170 MHz @ 50 mA/5 V - confirming suitability for audio-frequency switching and analog signal buffering where gain stability and low input drive are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - supports rail voltages up to 48 V automotive systems without breakdown
I_C	500 mA continuous - drives small relays, LED arrays, or sensor interface loads directly
h_FE	2000 min @ 100 µA - enables microcontroller GPIO-level base drive without external pre-amplification
V_CEsat	≤ 1 V @ 100 mA/0.1 mA - minimizes conduction loss in low-voltage switching applications
f_T	170 MHz - sufficient for AF amplification and fast-switching control loops up to ~100 kHz
R_thJS	≤ 210 K/W - defines thermal path from junction to solder point; requires PCB copper area ≥ 25 mm² for full-rated power
AEC-Q101	Qualified - validated for automotive under-hood and body-control module environments

3 (C)	Collector	High-current output node; sinks load current up to 500 mA with minimal saturation drop

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCV47,115 (Nexperia)	Same V_CEO/I_C/h_FE specs; identical SOT23-3 pinout; R_thJS = 220 K/W	No AEC-Q101 qualification; rated only for industrial temp range (−55 °C to +150 °C)	Select when automotive qualification is not required and cost sensitivity dominates.
MMBT5401LT1G (ON Semiconductor)	PNP complement; V_CEO = 150 V, h_FE = 60–250; lower gain, higher voltage rating	Used in complementary push-pull stages or high-side switching where polarity inversion is acceptable	Choose only for PNP-specific topologies; not a functional replacement for BCV47E6393HTSA1.

Compared with BCV47,115, BCV47E6393HTSA1 offers guaranteed automotive reliability but slightly tighter thermal margin; versus MMBT5401LT1G, it provides 10× higher gain and lower V_CEsat, making it superior for low-drive, high-efficiency switching.

FAQ

What is the maximum safe operating temperature for BCV47E6393HTSA1?

The junction temperature must not exceed +150 °C under any operating condition. With R_thJS ≤ 210 K/W and ambient ≤ +85 °C, continuous 500 mA operation requires at least 40 mm² of 2-oz copper on the collector pad to maintain T_j < 150 °C.

Can BCV47E6393HTSA1 be used in linear amplifier mode?

Yes - its h_FE remains stable from 100 µA to 100 mA, and V_CEsat stays below 1.5 V across that range. For linear use, bias the base to maintain V_CE ≥ 2 V and limit power dissipation to ≤360 mW with proper heatsinking.

Is BCV47E6393HTSA1 pin-compatible with BCV27?

Yes - both share identical SOT23-3 package and pin configuration (1=B, 2=E, 3=C). However, BCV27 has lower V_CEO (30 V) and V_CBO (40 V); substituting BCV47E6393HTSA1 into BCV27 designs is safe electrically but may require layout review for thermal margins.

Does BCV47E6393HTSA1 support pulsed operation beyond its DC ratings?

Yes - peak collector current reaches 800 mA for pulses ≤10 ms (duty cycle ≤2%). Pulse operation must respect the derating curve in Figure 5 of the datasheet: at t_p = 1 ms, allowable P_tot rises to ~1.2 W with proper PCB thermal design.
