Diodes Incorporated BCP5616TTC

Overview

BCP5616TTC from Diodes Incorporated is an 80V NPN medium-power transistor in SOT223 package, rated for 1A continuous collector current and 2W power dissipation, with V_CE(SAT) < 500 mV at 500 mA, used in AF driver stages and medium-power switching circuits in industrial control and audio output amplification.

For engineers reviewing the BCP5616TTC datasheet, BCP5616TTC pinout, BCP5616TTC application, or BCP5616TTC equivalent, key selection criteria include V_CEO = 80 V, h_FE = 63–250 (IC = 5–500 mA), f_T = 100–150 MHz, R_θJA = 45.6 °C/W, and SOT223 thermal performance under PCB copper area constraints.

Technical Context

This NPN bipolar junction transistor operates in linear amplification and saturated switching modes, with guaranteed BV_CEO ≥ 80 V and low saturation voltage enabling efficient operation in 24V industrial load drivers. Its f_T of 100–150 MHz supports audio-frequency signal amplification up to ~100 kHz with stable gain.

The device features a thermally enhanced SOT223 package with collector-connected tab, delivering R_θJL = 21.7 °C/W to PCB copper, and meets J-STD-020 Level 1 moisture sensitivity-suitable for standard reflow without bake preconditioning.

FAQ

What is the maximum safe operating voltage for BCP5616TTC in a common-emitter configuration?

The absolute maximum V_CEO is 80 V with open base, verified per JEDEC test conditions. In practical designs, derate to ≤64 V (80% of rating) for reliability in 48V systems with transients. The device's BV_CBO = 100 V further supports robustness against inductive kickback in relay/solenoid switching.

Can BCP5616TTC replace BC817-40 in SOT23 footprint designs?

No-BCP5616TTC uses SOT223, not SOT23, and has different pinout (Emitter-Base-Collector-Tab vs Emitter-Base-Collector). It cannot be substituted without PCB redesign. Its higher voltage, current, and thermal capability are intended for applications where BC817-40 would thermally saturate or avalanche.

Is the exposed collector tab electrically isolated from other pins?

No-the collector tab (pin 4) is electrically and thermally connected to pin 3 (collector). It must be routed to the same net and soldered to a dedicated copper pour. Isolation is not possible; any attempt to insulate the tab voids thermal performance ratings and violates JEDEC mounting guidelines.

Does BCP5616TTC require gate/base protection when driving inductive loads?

Yes-while the device has no integrated flyback diode, its V_CEO rating assumes external clamping. A reverse-biased fast recovery diode (e.g., 1N4148 or BAT54) must be placed across the inductive load to suppress V_L = −L·di/dt spikes and prevent secondary breakdown during turn-off.
