Product details

Overview

BCX6810E6327HTSA1 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for general-purpose audio-frequency amplification and switching. It delivers 1 A continuous collector current, 20 V V_CEO, 50–100 DC current gain (h_FE) at IC = 500 mA / V_CE = 1 V, and 0.5 V max V_CE(sat) at IC = 1 A / IB = 100 mA. It is used in automotive body control modules for relay driver stages.

For engineers reviewing the BCX6810E6327HTSA1 datasheet, BCX6810E6327HTSA1 pinout, BCX6810E6327HTSA1 application, or BCX6810E6327HTSA1 equivalent, key selection criteria include V_CEO rating, h_FE binning consistency across temperature, thermal resistance to soldering point (≤12 K/W), and AEC-Q101 qualification for automotive use.

Technical Context

This NPN BJT operates in linear or saturated switching mode with base-emitter forward bias enabling controlled collector current flow. Its 25 V V_CBO and 5 V V_EBO support robust bias network design, while f_T = 100 MHz (typ.) enables stable operation up to mid-frequency AF ranges.

The device uses a planar epitaxial structure with emitter ballasting for current uniformity. Thermal performance is defined by R_thJS ≤ 12 K/W, requiring PCB copper area optimization per AN077, and supports pulsed operation up to I_CM = 2 A for t_p ≤ 10 ms with duty cycle ≤ 2%.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	20 V - Maximum safe collector-emitter voltage before breakdown under open-base condition
h_FE (IC = 500 mA)	50–100 - Ensures predictable base drive sizing for 0.5–1 A load switching
V_CE(sat)	≤ 0.5 V @ IC = 1 A / IB = 100 mA - Limits conduction loss to ≤500 mW in saturated switch mode
f_T	100 MHz (typ.) - Supports stable small-signal amplification up to ~10 MHz with adequate gain margin
P_tot	3 W @ T_S ≤ 114 °C - Requires ≥2 cm² 2-oz copper pad for full power dissipation
R_thJS	≤12 K/W - Enables junction-to-solder-point thermal path modeling without external heatsink
AEC-Q101 Qualified	Yes - Validated for automotive applications including engine bay and cabin electronics

Pinout & Package

BCX6810E6327HTSA1 is housed in a surface-mount SOT-89 package with gull-wing leads, optimized for thermal transfer via exposed emitter tab. The package measures 4.5 mm × 2.5 mm × 1.5 mm and features standardized reel packaging (1000 pcs/reel, ø180 mm).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected directly to PCB thermal pad; primary heat path to board
2 (Collector)	Current source terminal	High-current output node; electrically isolated from thermal pad
3 (Base)	Control input	Receives low-current drive signal; requires series resistor to limit IB peak

Key Features

Feature	Design Value
High current capability	1 A continuous collector current supports direct driving of 12 V relays and solenoids
Low saturation voltage	V_CE(sat) ≤ 0.5 V minimizes power loss and self-heating in switching applications
Automotive qualification	AEC-Q101 compliance ensures reliability under thermal cycling, vibration, and humidity stress
Complementary pairing	Designed as NPN counterpart to BCX69 PNP for push-pull output stages
Pb-free RoHS packaging	SOT-89 leadframe meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile

Applications

IC Role / Device Role / Timing Role: NPN switch operating in saturation to close relay coil circuit.

Use Value: 0.5 V V_CE(sat) limits coil-side voltage drop to <2%, ensuring reliable relay pull-in at low battery voltage (9.5 V).

Use Scenario: PWM-based speed regulation of small brushed DC motors in HVAC actuators.

IC Role / Device Role / Timing Role: Low-side switching element handling 800 mA average motor current.

Use Value: 100 MHz f_T supports clean PWM edge fidelity up to 20 kHz without phase lag or overshoot.

LED Current Regulator

Audio Pre-amplifier Stage

Use Scenario: Constant-current sink for high-brightness LED strings in interior lighting.

IC Role / Device Role / Timing Role: Linear current regulator with emitter-degenerated feedback.

Use Value: h_FE = 50–100 enables stable 350 mA current setting with ±5% tolerance over –40°C to +125°C.

Use Scenario: First-stage voltage amplifier in car radio preamp circuits.

IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier biased at IC = 5 mA.

Use Value: V_(BR)CEO = 20 V provides headroom for 12 V rail with AC-coupled signal swing up to ±4 V peak.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCX68-16E6327HTSA1	h_FE = 85–160 @ IC = 500 mA - higher and wider gain bin	Better suited for low-base-drive designs where IB < 5 mA is required	Select when tighter h_FE matching or lower base current is critical
MMBT4401LT1G	V_CEO = 40 V, h_FE = 100–300 @ IC = 150 mA - higher voltage rating but lower current capability (IC = 600 mA)	Preferred for 24 V industrial systems; not AEC-Q101 qualified	Choose only for non-automotive 24 V applications requiring higher V_CEO

Compared with BCX68-16E6327HTSA1, this BCX6810 offers tighter h_FE control for predictable base drive; versus MMBT4401LT1G, it trades voltage headroom for automotive qualification and higher continuous current handling.

FAQ

Is BCX6810E6327HTSA1 pin-compatible with BCX69?

No - BCX6810E6327HTSA1 is an NPN transistor with pinout E-C-B (Emitter–Collector–Base) in SOT-89, while BCX69 is its PNP complement with identical mechanical footprint but reversed polarity and pin function (C-B-E). Direct substitution without circuit redesign will cause functional failure.

What is the maximum allowable PCB temperature at the soldering point?

The datasheet specifies P_tot = 3 W at T_S ≤ 114 °C, meaning the soldering point (case) temperature must not exceed 114 °C during continuous operation. Exceeding this reduces power derating per the P_tot vs. T_S curve and risks thermal runaway.

Does BCX6810E6327HTSA1 support pulse operation beyond 1 A?

Yes - it supports I_CM = 2 A for pulse widths ≤10 ms and duty cycle ≤2%, provided the average power remains within P_tot derating limits and thermal mass prevents junction overheating. Pulse testing must follow t_p < 300 µs, D < 2% conditions.

Can BCX6810E6327HTSA1 be used in linear amplifier configurations?

Yes - its f_T = 100 MHz and h_FE stability support common-emitter small-signal amplification up to ~10 MHz. However, linear operation requires careful thermal design due to P_tot limitation and V_CE biasing below 20 V to avoid second breakdown.
