Infineon Technologies BCP5610E6327HTSA1

Overview

BCP5610E6327HTSA1 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It features 80 V V_CEO, 1 A continuous collector current, 0.5 V typical V_CE(sat) at I_C = 500 mA / I_B = 50 mA, 100 MHz f_T, and SOT-223 surface-mount package. It is used in automotive amplifier bias circuits and industrial power supply pre-driver stages.

For engineers reviewing the BCP5610E6327HTSA1 datasheet, BCP5610E6327HTSA1 pinout, BCP5610E6327HTSA1 application, or BCP5610E6327HTSA1 equivalent, key selection criteria include V_CEO rating, DC current gain at high I_C, saturation voltage under defined drive conditions, thermal resistance (R_thJS ≤ 15 K/W), and AEC-Q101 qualification status.

Technical Context

This transistor operates as a medium-power NPN switch or linear amplifier with fixed-emitter configuration. Its 80 V V_CEO and 100 V V_CBO support operation in 48 V rail systems and flyback snubber networks. The h_FE range of 63–250 at I_C = 150 mA enables stable current amplification across temperature and production lots.

Designed for thermally constrained PCB layouts, it delivers 2 W total power dissipation at T_S ≤ 120 °C and exhibits R_thJS ≤ 15 K/W to soldering point. Its f_T = 100 MHz allows use in low-MHz switching control loops and AF signal buffering without phase degradation.

FAQ

Is BCP5610E6327HTSA1 pin-compatible with BCP54 or BCP55 variants?

Yes - all BCP54–BCP56 variants share identical SOT-223 pinout (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector). However, V_CEO and V_CBO ratings differ: BCP54 is rated for 45 V, BCP55 for 60 V, and BCP56 for 80 V. Substitution requires verification of voltage margin in the target circuit.

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies P_tot = 2 W at T_S ≤ 120 °C, where T_S is the soldering point temperature. Junction temperature must not exceed 150 °C. With R_thJS ≤ 15 K/W, sustained 2 W dissipation requires T_S ≤ 120 °C - meaning the PCB copper thermal pad must be maintained below this threshold under worst-case ambient and airflow conditions.

Does BCP5610E6327HTSA1 support pulse operation beyond its DC current rating?

Yes - the datasheet specifies I_CM = 1.5 A for pulse widths ≤ 10 ms with duty cycle ≤ 2%. This enables short-duration surge handling in relay driving or inrush limiting. Pulse derating curves in Figure 5 confirm permissible P_tot(max)/P_tot(DC) ratios up to 10× for t_p < 100 µs, provided thermal mass and layout support transient heat absorption.

How does the dual-collector configuration affect PCB layout?

The dual-collector (Pins 2 and 4) must be routed to the same net - typically the high-side power rail. This configuration lowers effective current density per pin and improves thermal spreading into the copper plane. Layout best practice is to connect both pins to a common wide copper pour with ≥4 thermal vias to inner ground/power planes, avoiding narrow traces that concentrate heat.
