Diodes Incorporated BCP5616TA

Overview

BCP5616TA from ON Semiconductor is an NPN silicon planar medium-power transistor in SOT-223 package, rated for 1 A continuous collector current, 80 V V_CEO, and 0.5 V V_CE(sat) at I_C=500 mA/I_B=50 mA; used in audio frequency driver and output stages of consumer and industrial amplifiers.

For engineers reviewing the BCP5616TA datasheet, BCP5616TA pinout, BCP5616TA application, or BCP5616TA equivalent, key selection factors include h_FE range (100–160 at I_C=150 mA), f_T = 125 MHz, thermal capability (P_tot = 2 W at T_amb=25°C), and complementary pairing with BCP53 for push-pull configurations.

Technical Context

This device operates as a linear or switching NPN transistor with DC current gain binned to h_FE = 100–160 at I_C = 150 mA and V_CE = 2 V. Its 125 MHz transition frequency supports mid-frequency AF amplification up to ~10 kHz with stable gain margin.

The SOT-223 package provides enhanced thermal dissipation over SOT-23, enabling 2 W power handling with PCB copper pour. Absolute maximum ratings include V_CBO = 100 V, V_CEO = 80 V, and T_j range from –55°C to +150°C - suitable for non-automotive industrial environments.

FAQ

What is the guaranteed h_FE range for BCP5616TA?

The BCP5616TA is binned to h_FE = 100–160 when measured at I_C = 150 mA and V_CE = 2 V. This range is verified per ON Semiconductor's production test flow and applies across the full operating temperature range of –55°C to +150°C.

Can BCP5616TA be used in place of BCP56-16 without derating?

Yes - BCP5616TA is the tape-and-reel packaged version of the BCP56-16 variant, sharing identical electrical specifications, thermal limits, and pinout. No derating is required; only packaging and reel orientation differ per JEDEC J-STD-020 standards.

Is the collector tab electrically isolated in SOT-223?

No - the exposed collector tab (pin 3) is internally connected to the collector semiconductor region and is not insulated. It must be electrically tied to the collector net on the PCB and may require clearance from adjacent grounded planes per creepage/clearance rules.

What is the maximum safe operating area (SOA) limit at 100°C case temperature?

At T_C = 100°C, the SOA limit is defined by the derated P_tot ≈ 1.2 W and V_CE ≤ 40 V for DC operation. Pulse operation (≤300 µs, ≤2% duty) extends V_CE to 60 V at I_C = 1 A, per the manufacturer's SOA curve in datasheet Figure 4.
