Infineon Technologies BCP5610H6327XTSA1

Overview

BCP5610H6327XTSA1 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, h_FE ≥ 63 at I_C = 150 mA, and SOT223 surface-mount package with four terminals (B-C-E-C).

For engineers reviewing the BCP5610H6327XTSA1 datasheet, BCP5610H6327XTSA1 pinout, BCP5610H6327XTSA1 application, or BCP5610H6327XTSA1 equivalent, this part supports high-current AF amplification, low-saturation switching in power management blocks, thermal-stable biasing networks, and complementary PNP pairing with BCP51–BCP53 series.

Technical Context

This transistor operates as a medium-power general-purpose NPN device optimized for linear amplification and saturated switching. Its 80 V V_CEO rating enables use in 24–48 V rail systems, while its 2 W total power dissipation (T_S ≤ 120 °C) and R_thJS ≤ 15 K/W support thermally constrained PCB layouts.

The device delivers h_FE = 63–250 across I_C = 5 mA to 500 mA, with f_T = 100 MHz at I_C = 50 mA/V_CE = 10 V, confirming suitability for audio-band signal gain and fast-switching control paths without RF instability concerns.

Key Specifications

Pinout & Package

FAQ

Is BCP5610H6327XTSA1 pin-compatible with BCP54 or BCP55 variants?

No. While all share the SOT223-4 package and identical pin 1–4 assignment (B-C-E-C), BCP5610H6327XTSA1 has higher V_CEO (80 V) and V_CBO (100 V) than BCP54 (45 V) and BCP55 (60 V). Substituting without verifying voltage margin may cause premature breakdown in high-rail designs.

What is the maximum safe operating temperature for continuous use?

The junction temperature must not exceed 150 °C. With R_thJS ≤ 15 K/W and P_tot = 2 W at T_S ≤ 120 °C, the device remains within safe limits if the solder-point temperature stays at or below 120 °C-achievable using ≥2 cm² 2-oz copper pour under the tab.

Does this transistor require a base resistor in all applications?

Yes. Base current must be limited to prevent damage: I_B ≤ 100 mA DC (200 mA peak). For example, driving from a 3.3 V MCU GPIO with h_FE = 100 and I_C = 500 mA requires ~5 mA I_B, so a 560 Ω series resistor ensures safe operation and avoids thermal runaway.

Can BCP5610H6327XTSA1 replace BC817 in SOT-23 designs?

No. BC817 uses SOT-23 (3-pin, 0.65 mm pitch); BCP5610H6327XTSA1 uses SOT223 (4-pin, 2.3 mm pitch, exposed tab). Footprint, thermal path, and pin count are incompatible-PCB redesign and layout validation are required for any substitution.
