Product details

Overview

BCV46E6327HTSA1 from Infineon Technologies is a PNP silicon Darlington transistor in SOT23 package, rated for 60 V V_CEO, 500 mA I_C, and 360 mW P_tot at T_S ≤ 74 °C, with h_FE ≥ 2000 at I_C = 10 mA and V_CE = 5 V, used in low-power audio preamplifier stages and relay driver circuits.

For engineers reviewing the BCV46E6327HTSA1 datasheet, BCV46E6327HTSA1 pinout, BCV46E6327HTSA1 application, or BCV46E6327HTSA1 equivalent, key selection criteria include its high DC current gain (h_FE up to 20,000), low V_CEsat ≤ 1 V at I_C = 100 mA/I_B = 0.1 mA, complementary NPN pairing with BCV47, AEC-Q101 qualification, and RoHS-compliant SOT23 packaging.

Technical Context

This Darlington pair integrates two cascaded PNP transistors on a single die to achieve high current gain while maintaining compact SOT23 footprint. It operates with emitter-base breakdown voltage V_(BR)EBO = 10 V and collector-base capacitance C_cb = 4.5 pF at V_CB = 10 V, enabling stable low-frequency amplification and switching.

The device supports pulsed operation up to I_CM = 800 mA (t_p ≤ 10 ms), exhibits f_T = 200 MHz at I_C = 50 mA/V_CE = 5 V, and maintains junction temperature capability up to 150 °C - suitable for thermally constrained automotive and industrial control modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - maximum safe collector-emitter voltage before breakdown in open-base configuration
I_C	500 mA - continuous DC collector current rating under thermal limits (T_S ≤ 74 °C)
h_FE	2000–20000 - DC current gain range across operating conditions, enabling high-sensitivity base drive reduction
V_CEsat	≤ 1 V at I_C = 100 mA/I_B = 0.1 mA - low saturation voltage minimizes power loss in switching applications
f_T	200 MHz - transition frequency confirms usable bandwidth up to mid-VHF for signal amplification
R_thJS	≤ 210 K/W - thermal resistance from junction to soldering point, critical for PCB copper pour design
AEC-Q101	Qualified - validated for automotive electronic systems per stress test requirements

Pinout & Package

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base	Input control terminal; requires current-limited drive due to Darlington architecture's high h_FE
2 (E)	Emitter	Common reference node; internally connected to first transistor's emitter and second's base
3 (C)	Collector	Output current sink; handles full load current with minimal V_CEsat drop

Key Features

Feature	Design Value
High DC current gain	h_FE ≥ 2000 at I_C = 10 mA reduces required base drive current by >90% vs. single transistor
Low saturation voltage	V_CEsat ≤ 1 V at I_C = 100 mA enables efficient switching in 5 V logic-controlled loads
AEC-Q101 qualified	Validated for automotive ambient temperature range (−40 °C to +125 °C case) and reliability stress tests
Complementary NPN pairing	BCV47 matches BCV46 in package, ratings, and gain profile for push-pull output stage design
Pb-free & RoHS compliant	Meets EU Directive 2011/65/EU; no lead content in terminations or mold compound

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCV47E6327HTSA1	NPN complement; identical SOT23 package, same V_CEO/I_C/h_FE specs but opposite polarity	Required for push-pull or phase-inverting configurations where NPN topology is needed	Select when designing complementary output stages or inverting amplifiers requiring matched gain and thermal behavior
MMDT3906-7-F	Single PNP transistor (not Darlington); lower h_FE (min 100), higher V_CEsat (0.4 V @ 10 mA), same SOT363 package	Suitable only for low-gain, low-current switching where Darlington-level gain is unnecessary	Choose for cost-sensitive, non-critical switching where reduced gain and faster turn-off are acceptable trade-offs

Compared with BCV46E6327HTSA1, BCV47E6327HTSA1 provides polarity-matched performance for dual-transistor topologies, while MMDT3906-7-F offers simpler biasing and lower storage time at the expense of gain and current drive capability - making it viable only where Darlington advantages are not required.

FAQ

What is the maximum allowable junction temperature for BCV46E6327HTSA1?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Infineon datasheet. Operation beyond this limit risks permanent degradation of the Darlington structure. Thermal design must ensure R_thJS ≤ 210 K/W and board-level heat sinking maintains T_j within spec under worst-case I_C and ambient conditions.

Does BCV46E6327HTSA1 have an integrated base-emitter resistor?

No, BCV46E6327HTSA1 does not include internal base-emitter resistors. It is a bare Darlington pair requiring external base current limiting. This differs from digital transistors (e.g., IMX series) and allows full flexibility in bias network design for precision gain and switching speed control.

Can BCV46E6327HTSA1 replace BCV26 in existing designs?

No - BCV46 has V_CEO = 60 V and V_CBO = 80 V, versus BCV26's 30 V and 40 V ratings. Substituting BCV46 for BCV26 may cause overstress in circuits operating near BCV26's voltage limits. The reverse substitution is unsafe due to BCV26's lower current and gain capability.

Is BCV46E6327HTSA1 suitable for linear amplifier applications?

Yes, it is characterized for linear operation with h_FE stability across I_C = 100 µA to 500 mA and V_CE = 1–5 V. Its low V_CEsat and predictable gain make it appropriate for Class-A preamplifiers, though thermal derating must be applied above 74 °C case temperature to maintain P_tot ≤ 360 mW.
