Product details

Overview

BCR 162L3 E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 4.7 kΩ), designed for low-power switching, level-shifting, and interface driver applications in compact consumer and industrial control circuits. It delivers V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA/I_B = 0.5 mA, and f_T = 200 MHz, enabling fast switching in logic buffer and LED driver stages.

For engineers reviewing the BCR 162L3 E6327 datasheet, BCR 162L3 E6327 pinout, BCR 162L3 E6327 application, or BCR 162L3 E6327 equivalent, key selection criteria include its SC75 package thermal resistance (R_thJS ≤ 60 K/W), guaranteed input voltage thresholds (V_i(on) = 1–2.5 V, V_i(off) = 0.8–1.5 V), and built-in resistor ratio tolerance (R1/R2 = 0.9–1.1).

Technical Context

This digital transistor integrates two matched 4.7 kΩ bias resistors to enable single-resistor base drive-eliminating external components in saturated-switch configurations. Its PNP topology supports active-low logic interfacing and high-side load switching where emitter is tied to supply rail.

The SC75 package provides enhanced thermal performance over SOT-23 variants (R_thJS ≤ 60 K/W vs. ≤ 240 K/W for BCR162), supporting higher continuous current at elevated board temperatures up to T_S = 135 °C before derating begins.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter blocking voltage under open-base conditions; defines safe operating range for 24 V and 36 V rail switching.
I_C	100 mA - Continuous collector current rating; supports driving small relays, LEDs, or logic inputs without external heat sinking.
V_CE(sat)	≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in on-state operation.
f_T	200 MHz - Transition frequency confirms suitability for signal switching up to ~20 MHz square waves with minimal delay distortion.
R1 / R2	4.7 kΩ ±23% - Matched internal base resistors simplify PCB layout and reduce component count in digital interface circuits.
R1/R2 ratio	0.9–1.1 - Tight resistor matching ensures stable turn-on/turn-off thresholds across temperature and process variation.
C_cb	3 pF - Low collector-base capacitance limits Miller effect, preserving switching speed in high-frequency gate drivers.

Pinout & Package

BCR 162L3 E6327 is housed in an SC75 (SOT-416) surface-mount package: 1.6 mm × 0.8 mm footprint, 0.4 mm nominal height, 3-pin configuration with gull-wing leads. Thermal pad is not present; soldering to copper pour improves R_thJA.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base connection via R1–R2 divider network	Input node for TTL/CMOS-compatible logic drive; internal R1 connects to this pin, R2 ties base to emitter.
2 (E)	Emitter terminal	Common reference for both resistors and output current path; connected to positive supply in high-side switch configurations.
3 (C)	Collector terminal	Switched output node; sinks current when transistor is on; requires external load between collector and ground.

Key Features

Feature	Design Value
Integrated bias network	Eliminates two external resistors-reduces BOM count and layout area in space-constrained designs like wearables and IoT sensors.
V_i(on)/V_i(off) thresholds	Guaranteed 1–2.5 V turn-on and 0.8–1.5 V turn-off voltages ensure reliable logic-level compatibility with 3.3 V and 5 V microcontrollers.
SC75 thermal performance	R_thJS ≤ 60 K/W enables 250 mW dissipation at T_S = 135 °C-supports higher ambient operation than SOT-23 equivalents.
Matched R1/R2 ratio	0.9–1.1 tolerance maintains consistent h_FE-independent switching behavior across production lots and temperature ranges.

Applications

LED Driver Stage

Microcontroller Interface

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V GPIO pins in battery-powered sensor nodes.

IC Role / Device Role / Timing Role: Digital switch providing current sink path from LED anode (to V_CC) to ground through collector.

Use Value: Built-in R1/R2 eliminates need for discrete base resistors, reducing component count and improving assembly yield.

Use Scenario: Level-shifting 5 V logic signals to 3.3 V microcontroller inputs in mixed-voltage industrial controllers.

IC Role / Device Role / Timing Role: Active-low inverter with defined V_i(off) threshold ensuring clean signal transition below 1.5 V.

Use Value: Guaranteed V_i(off) ≤ 1.5 V prevents false triggering during slow-rising or noisy input edges.

Relay Driver Circuit

Power Supply Enable Switch

Use Scenario: Controlling 12 V/50 mA reed relay coils in HVAC control panels using MCU outputs.

IC Role / Device Role / Timing Role: Saturated PNP switch connecting relay coil between V_CC and collector, with emitter tied to 12 V rail.

Use Value: V_CE(sat) ≤ 0.3 V limits relay coil voltage drop to <1% of supply-ensuring reliable pull-in at low temperature.

Use Scenario: Enabling/disabling auxiliary 5 V LDO output based on system sleep/wake state in portable medical devices.

IC Role / Device Role / Timing Role: High-side enable switch placing BCR162L3 between LDO input and output to gate power flow.

Use Value: 50 V V_CEO rating provides margin against load-dump transients in automotive-adjacent power systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR162T E6327	Same electrical specs but packaged in SC70 (SOT-323); R_thJS = 165 K/W vs. 60 K/W for BCR162L3.	Lower thermal capability limits continuous I_C in high-density layouts or elevated ambient environments.	Select BCR162T only if SC70 footprint is required and board-level thermal management is robust.
NSV162L3T1G	PNP digital transistor with identical R1/R2 values and SC75 package; V_CEO = 50 V, but V_CE(sat) max = 0.4 V (vs. 0.3 V).	Slightly higher saturation voltage increases conduction loss by ~33% at 10 mA, affecting efficiency-critical LED drivers.	Acceptable for non-efficiency-sensitive logic interfaces; verify V_CE(sat) impact in high-duty-cycle switching.

Compared with BCR162T and NSV162L3T1G, BCR162L3 E6327 offers superior thermal performance and tighter V_CE(sat), making it optimal for compact, thermally constrained designs requiring sustained 100 mA switching without derating.

FAQ

Is BCR 162L3 E6327 RoHS compliant and halogen-free?

Yes, BCR 162L3 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 bromine and chlorine content below 900 ppm each.

What is the maximum allowable base drive current for reliable operation?

The absolute maximum base current is limited by R1 power dissipation: with R1 = 4.7 kΩ and V_i(on) ≤ 2.5 V, I_B ≤ 532 µA. Exceeding this risks resistor drift or long-term parametric shift; design should maintain I_B ≤ 400 µA for 10-year reliability.

Can BCR 162L3 E6327 replace a standard PNP BJT like BC807 in existing designs?

No-BCR 162L3 is not a drop-in replacement for BC807. It integrates base resistors and lacks direct base access; substituting it requires removing external R_B and verifying that V_i(on)/V_i(off) thresholds match the driving source's logic levels.

Does the SC75 package support automated optical inspection (AOI) after reflow?

Yes, the SC75 package's gull-wing leads and 0.65 mm pitch are compatible with standard AOI systems. The 0.4 mm lead coplanarity and defined marking layout ('L3' laser etch) enable reliable fiducial detection and solder-joint defect identification per IPC-A-610 Class 2 requirements.
