Product details

Overview

BCR 153T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 2.2 kΩ), designed for low-power switching, level-shifting, and interface driver applications in compact consumer and industrial control circuits. It supports 50 V V_CEO, 100 mA I_C, 0.3 V V_CE(sat) at 20 mA/1 mA drive, and operates up to 150 °C junction temperature.

For engineers reviewing the BCR 153T E6327 datasheet, BCR 153T E6327 pinout, BCR 153T E6327 application, or BCR 153T E6327 equivalent, key selection criteria include its SC75 package thermal resistance (R_thJS ≤ 165 K/W), input voltage thresholds (V_i(on) ≤ 2.5 V, V_i(off) ≥ 0.8 V), and guaranteed h_FE ≥ 20 at 20 mA - critical for reliable logic-level interfacing and discrete gate driving.

Technical Context

This digital transistor integrates two matched on-chip resistors to form a single-base resistor network, eliminating external bias components in simple switching configurations. Its PNP topology enables active-low control, sink-current operation, and direct compatibility with TTL/CMOS logic outputs.

The SC75 package provides a thermally optimized footprint for surface-mount assembly in space-constrained PCBs, with defined soldering point thermal resistance and pulse-load derating curves validated per Infineon's thermal application notes. Device behavior is characterized under pulsed conditions (t < 300 µs, D < 2%) to ensure stable DC gain and saturation performance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter blocking voltage before breakdown; defines safe operating range in 24 V and 36 V interface circuits.
I_C	100 mA - Continuous collector current rating; supports driving LEDs, small relays, or MOSFET gates without external current limiting.
V_CE(sat)	≤ 0.3 V at I_C = 20 mA, I_B = 1 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching.
h_FE	≥ 20 at I_C = 20 mA, V_CE = 5 V - Guaranteed DC current gain ensures predictable base drive requirements and noise margin in digital logic interfaces.
R1 / R2	2.2 kΩ ±30% - Integrated bias resistors enable direct connection to 3.3 V or 5 V logic without external components; ratio tolerance (0.9–1.1) ensures consistent turn-on behavior.
f_T	200 MHz typical - Transition frequency supports fast edge rates in signal conditioning and moderate-speed digital isolation applications.
P_tot	250 mW at T_S ≤ 109 °C - Total power dissipation limit under specified heatsink temperature; requires board-level thermal design for sustained operation.

Pinout & Package

BCR 153T E6327 is housed in the SC75 (SOT-416) plastic surface-mount package: 1.6 mm × 0.8 mm footprint, 0.4 mm nominal height, single-row 3-pin configuration with gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base terminal	Connected internally to R1 and R2; accepts logic-level input to enable PNP conduction; no external base resistor required.
2 (E)	Emitter terminal	Common emitter node; tied to system ground or negative rail in sink-switching configurations.
3 (C)	Collector terminal	Output node carrying load current; connected to positive supply via load (e.g., LED anode or relay coil).

Key Features

Feature	Design Value
Integrated dual-resistor bias network	R1 = R2 = 2.2 kΩ ±30%, enabling direct logic-level drive with zero external components.
Guaranteed DC current gain	h_FE ≥ 20 at I_C = 20 mA ensures robust switching margin across process and temperature variation.
Low saturation voltage	V_CE(sat) ≤ 0.3 V reduces conduction loss and self-heating in battery-powered or thermally constrained designs.
Thermally rated SC75 package	R_thJS ≤ 165 K/W allows predictable thermal management using standard PCB copper pour techniques.
Logic-compatible input thresholds	V_i(on) ≤ 2.5 V and V_i(off) ≥ 0.8 V ensure reliable operation with 3.3 V CMOS and 5 V TTL output families.

Applications

LED Driver Circuit

Microcontroller Interface

Use Scenario: Driving indicator or status LEDs from low-voltage microcontroller GPIO pins.

IC Role / Device Role / Timing Role: PNP digital transistor acting as a current-sinking switch controlled by active-low MCU output.

Use Value: Eliminates need for discrete base resistor; 0.3 V V_CE(sat) ensures >95% LED forward voltage utilization at 20 mA.

Use Scenario: Level-shifting between 3.3 V logic and 5 V peripheral inputs requiring active-low enable signals.

IC Role / Device Role / Timing Role: Logic-level translator providing inverted, buffered output with defined VIH/VIL thresholds.

Use Value: Input voltage thresholds (0.8–2.5 V) match standard CMOS logic margins; h_FE ≥ 20 guarantees full saturation under worst-case drive conditions.

Relay Driver Stage

Power Supply Enable Switch

Use Scenario: Controlling small signal relays (≤ 100 mA coil current) in industrial I/O modules.

IC Role / Device Role / Timing Role: High-side switch driver that sinks relay coil current to ground when enabled.

Use Value: 50 V V_CEO safely handles relay back-EMF spikes; integrated R1/R2 prevents accidental turn-on during MCU reset.

Use Scenario: Enabling/disabling auxiliary power rails (e.g., 3.3 V or 5 V) in portable electronics based on system state.

IC Role / Device Role / Timing Role: Low-leakage, low-dropout enable switch placed between regulator output and load.

Use Value: ICBO ≤ 100 nA ensures minimal standby current; SC75 footprint saves board area versus SOIC alternatives.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR 152T E6327	Same SC75 package, but NPN polarity; R1 = 2.2 kΩ, R2 = open (single-resistor configuration).	Requires active-high logic drive instead of active-low; unsuitable for direct replacement where polarity inversion is not acceptable.	Select only when circuit topology mandates NPN sink switching and base bias simplification is prioritized over matched resistor ratio.
NSVD120DP03MXV6T1G	PNP digital transistor in SOT-416 (SC75); R1 = 4.7 kΩ, R2 = 4.7 kΩ; V_CEO = 50 V, I_C = 100 mA, V_CE(sat) = 0.3 V.	Higher input resistance increases minimum drive voltage requirement; identical thermal and switching specs allow drop-in use where higher VIH is acceptable.	Prefer when tighter resistor tolerance (±5%) or AEC-Q101 qualification is required; verify Vi(on) margin with target logic family.

Compared with BCR 153T E6327, BCR 152T E6327 offers complementary NPN functionality but lacks matched R1/R2 symmetry, while NSVD120DP03MXV6T1G provides tighter resistor tolerance and automotive qualification at the cost of higher input threshold voltage - making BCR 153T optimal for cost-sensitive, logic-compatible PNP switching where resistor matching ensures consistent turn-on behavior.

FAQ

Is BCR 153T E6327 RoHS compliant and halogen-free?

Yes. BCR 153T E6327 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SC75 package uses lead-free matte tin plating, and material declarations confirm absence of brominated flame retardants and chlorine-based compounds above threshold limits.

What is the maximum allowable continuous collector current at 85°C ambient?

At T_A = 85 °C, derated current is determined by thermal resistance and power limit. With R_thJA ≈ 300 K/W (typical for SC75 on 2-layer board), P_tot drops to ~165 mW at 85 °C, supporting I_C ≤ 82 mA continuously at V_CE(sat) = 0.3 V - verified via Infineon's P_tot vs. T_S curve for BCR153T.

Can BCR 153T E6327 be used in linear amplifier mode?

No. BCR 153T E6327 is characterized and qualified exclusively for switching operation. Its integrated resistors and gain profile (h_FE ≥ 20 only at I_C = 20 mA) are optimized for saturated on/off states, not analog amplification. Linear use risks thermal instability and undefined bias point due to internal resistor loading.

Does the device have built-in ESD protection?

No. BCR 153T E6327 does not integrate dedicated ESD protection diodes. It exhibits HBM ESD rating of ±2 kV (Class 2 per JESD22-A114), meaning external protection (e.g., series resistor + TVS) is recommended for handling-sensitive environments or board-level ESD events exceeding this level.
