Product details

Overview

BCR583E6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), rated for 50 V V_CEO, 500 mA I_C, and 330 mW P_tot at T_S ≤ 79 °C, commonly used in automotive LED driver and logic-level interface circuits.

For engineers reviewing the BCR583E6327HTSA1 datasheet, BCR583E6327HTSA1 pinout, BCR583E6327HTSA1 application, or BCR583E6327HTSA1 equivalent, key selection criteria include input threshold voltages (V_i(off) = 0.6–1.5 V, V_i(on) = 1.1–2.5 V), h_FE ≥ 70 at 50 mA, V_CE(sat) ≤ 0.3 V, and AEC-Q101 qualification for automotive use.

Technical Context

This digital transistor integrates two matched 10 kΩ bias resistors to enable direct TTL/CMOS logic-level drive without external components. Its PNP configuration supports high-side switching in low-voltage control paths where emitter-follower or saturated switch operation is required.

Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and operates across –65 °C to +150 °C storage and junction temperature ranges, with thermal resistance R_thJS ≤ 215 K/W ensuring stable performance under pulsed load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin.
I_C	500 mA - Continuous collector current rating; supports driving medium-power LEDs or relays directly.
V_CE(sat)	≤ 0.3 V at I_C = 50 mA, I_B = 2.5 mA - Low saturation voltage minimizes power loss in switching mode.
h_FE	≥ 70 at I_C = 50 mA, V_CE = 5 V - Sufficient DC gain for reliable on/off control with standard logic outputs.
R1 / R2	10 kΩ ±30%, ratio 0.9–1.1 - Matched internal resistors eliminate external bias network, reducing BOM count and layout area.
f_T	150 MHz typical - Supports fast switching up to ~10 MHz square-wave operation in digital interface applications.
AEC-Q101	Qualified - Meets automotive stress test requirements for temperature cycling, HTRB, HTSL, and ESD, enabling use in engine control and body electronics.

Pinout & Package

Supplied in SOT-23 (TSOP-3) plastic package with gull-wing leads, 1.3 mm pitch, and RoHS-compliant matte tin plating. Pin 1 = Base (with internal R1/R2 network), Pin 2 = Emitter, Pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Input node connected to internal R1–R2 divider	Accepts logic-level signals; R1 pulls base high, R2 pulls base to emitter - enables clean turn-off without floating base.
2 (Emitter)	PNP emitter terminal	Connected to supply rail in high-side switch configuration; defines reference for input thresholds and saturation behavior.
3 (Collector)	Output current sink terminal	Drives load to ground; current path defined by V_CE and h_FE; requires external load between V_CC and collector.

Key Features

Feature	Design Value
Integrated bias network	Eliminates need for two external resistors, reducing PCB footprint and assembly cost in high-volume automotive modules.
Logic-compatible input thresholds	V_i(on) ≤ 2.5 V and V_i(off) ≥ 0.6 V ensure robust switching with 3.3 V and 5 V microcontrollers without level-shifting.
AEC-Q101 qualification	Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock per JEDEC standards.
SOT-23 package	Standardized 3-pin surface-mount outline compatible with automated pick-and-place and reflow processes; footprint matches BC846/BC856 families.

Applications

IC Role / Device Role: Logic-level translator and current amplifier for relay or MOSFET gate drive.

Use Value: 500 mA I_C rating supports direct drive of small signal relays (e.g., 12 V/100 mW coil), removing need for secondary transistor stage.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR583H6327XTSA1	Same die, tape-and-reel packaging differs (3,000 vs. 10,000 pcs/reel); identical electrical specs and AEC-Q101 qualification.	No functional difference; selected based on volume procurement and line-side reel size constraints.	Prefer for high-volume SMT lines requiring larger reels to reduce changeover frequency.
NSV5831M3T5G	PNP digital transistor with R1 = R2 = 10 kΩ, but only AEC-Q100 qualified (not Q101); f_T = 100 MHz (vs. 150 MHz).	Limited to non-safety-critical cabin electronics due to lower qualification grade and reduced bandwidth.	Acceptable for infotainment or comfort systems where extended temperature reliability is less stringent.

Compared with BCR583H6327XTSA1, this variant offers identical performance in a different reel format; versus NSV5831M3T5G, it delivers higher switching speed and full AEC-Q101 compliance-critical for powertrain and chassis control nodes.

FAQ

Is BCR583E6327HTSA1 suitable for 24 V automotive systems?

Yes. With V_CEO = 50 V and AEC-Q101 qualification, it supports 24 V nominal systems including transient spikes up to 40 V. Its V_CE(sat) ≤ 0.3 V at 50 mA ensures minimal self-heating during continuous operation in tail light or HVAC modules.

Can BCR583E6327HTSA1 replace a standard PNP BJT like BC857?

Only with circuit redesign. Unlike BC857, BCR583E6327HTSA1 integrates base bias resistors - connecting it directly in place of a bare BJT will cause incorrect biasing. It replaces BC857 + two 10 kΩ resistors in one SOT-23 footprint.

What is the maximum operating temperature for continuous DC operation?

The junction temperature must not exceed 150 °C. At ambient 85 °C, derating begins above T_S = 79 °C per the P_tot vs. T_S curve; maximum continuous I_C drops to ~350 mA at 100 °C solder point temperature.

Does this part support PWM switching at 10 kHz?

Yes. With f_T = 150 MHz and V_CE(sat) settling in <100 ns (per typical switching waveforms in Infineon AN077), it fully supports 10 kHz PWM for LED dimming and motor enable control without significant switching loss or delay.
