Infineon Technologies BCP5310E6327HTSA1

Overview

BCP5310E6327HTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It features 80 V collector-emitter breakdown voltage (V_(BR)CEO), 1 A continuous collector current (I_C), 0.5 V collector-emitter saturation voltage (V_CE(sat)) at I_C = 500 mA / I_B = 50 mA, DC current gain (h_FE) of 63–100 at I_C = 150 mA, and 125 MHz transition frequency (f_T). It is used in automotive amplifier output stages and industrial power control circuits.

For engineers reviewing the BCP5310E6327HTSA1 datasheet, BCP5310E6327HTSA1 pinout, BCP5310E6327HTSA1 application, or BCP5310E6327HTSA1 equivalent, key selection criteria include its V_CE(sat) performance under high-current switching, thermal resistance (R_thJS ≤ 15 K/W), AEC-Q101 qualification, complementary NPN pairing with BCP56, and SOT223 package suitability for surface-mount thermal management.

Technical Context

This PNP transistor operates in linear amplification and saturated-switching modes, supporting DC biasing and pulse-driven loads up to 1.5 A peak (I_CM). Its f_T = 125 MHz enables stable operation in AF and low-MHz switching applications, while V_(BR)CBO = 100 V ensures robustness against transient voltage spikes across collector-base junctions.

The device is characterized at T_A = 25°C with validated h_FE min/max spread (63–100 @ I_C = 150 mA), V_BE(ON) = 1 V typical at I_C = 500 mA, and guaranteed V_CE(sat) ≤ 0.5 V - critical for minimizing conduction loss in high-current emitter-follower configurations.

Key Specifications

Pinout & Package

FAQ

Is BCP5310E6327HTSA1 pin-compatible with BCP53-16?

Yes - both share identical SOT223 pinout (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector tab) and mechanical footprint. The "10" and "16" denote h_FE gain bins, not physical differences. No layout change is required when upgrading between them.

What is the maximum allowable PCB copper area for thermal performance?

Per Infineon Application Note AN077, a minimum 100 mm² copper pour connected to Pin 4 (collector tab) reduces effective R_thJA to ~60 K/W. For 2 W dissipation at 120°C case temperature, ≥200 mm² is recommended to maintain junction temperature below 150°C in still air.

Does this transistor support pulsed operation beyond 1 A?

Yes - peak collector current I_CM is rated at 1.5 A for pulse widths ≤10 ms (duty cycle ≤2%). Pulse derating curves confirm safe operation up to 3 A for 100 µs pulses when using adequate PCB copper and ambient temperature ≤85°C.

Can BCP5310E6327HTSA1 replace BC857 in SOT23 packages?

No - BCP5310E6327HTSA1 uses SOT223 (4-pin, collector-tab package) and handles 1 A continuously, whereas BC857 is a 100 mA SOT23 PNP with different pinout, gain profile, and thermal limits. Direct replacement would require PCB redesign and validation of thermal and drive requirements.
