Infineon Technologies BCR39PN-E6327

Overview

BCR39PN-E6327 from Infineon Technologies is a dual NPN/PNP silicon digital transistor array in SOT-363 package, integrating bias resistors (R1 = 10 kΩ, R2 = 47 kΩ) for direct logic-level interfacing. It supports switching, inverting, and driver functions with V_CEO = 50 V, I_C = 100 mA per transistor, and AEC-Q101 qualification for automotive interface circuits.

For engineers reviewing the BCR39PN-E6327 datasheet, BCR39PN-E6327 pinout, BCR39PN-E6327 application, or BCR39PN-E6327 equivalent, key selection criteria include guaranteed input resistor ratio (R1/R2 = 0.19–0.24), dual-channel galvanic isolation, V_CE(sat) ≤ 0.3 V at I_C = 10 mA/I_B = 0.5 mA, and operation across –40 °C to 125 °C junction temperature.

Technical Context

This device implements two electrically isolated bipolar transistors - one NPN and one PNP - within a single SOT-363 package, each with monolithically integrated base bias resistors. The fixed R1/R2 ratio enables predictable turn-on/turn-off thresholds without external components.

It operates as a logic-compatible switch: Vi(on) = 0.5–1.4 V and Vi(off) = 0.5–1 V ensure compatibility with 3.3 V and 5 V CMOS/TTL outputs, while f_T = 150 MHz (typ.) supports high-speed digital switching up to ~10 MHz edge rates in buffered applications.

FAQ

What is the maximum allowable continuous collector current per transistor?

The absolute maximum DC collector current is 100 mA per transistor, specified at T_S = 115 °C. Derating is required above this case temperature: P_tot decreases linearly to zero at 150 °C junction temperature, as defined in the thermal resistance curve (R_thJS ≤ 140 K/W).

Does BCR39PN-E6327 support 1.8 V logic input levels?

No - Vi(on) is specified as 0.5–1.4 V at I_C = 2 mA, meaning reliable turn-on requires ≥1.4 V under worst-case conditions. For 1.8 V logic, BCR38PN-E6327 (Vi(on) = 0.4–1.2 V) is the recommended variant with identical pinout and package.

Can this device replace discrete transistor + resistor combinations in new designs?

Yes - BCR39PN-E6327 integrates two matched transistors with precision R1/R2 bias networks (tolerance ±30 %), eliminating four external resistors and reducing PCB area by >40 % compared to discrete solutions while improving thermal coupling and switching consistency.

Is there a recommended PCB layout guideline for thermal performance?

Yes - use minimum 10 mm² copper pour connected to pins 1 (E1) and 4 (E2) as thermal pads, with ≥2 internal thermal vias per pad to inner ground plane. Maintain ≥0.2 mm clearance from adjacent traces to avoid solder wicking during reflow, per Infineon Application Note AN077.
