Nexperia USA Inc. BC53-10PA,115

Overview

BC53-10PA,115 from Nexperia is a PNP medium power transistor in SOT1061 leadless ultra-thin SMD package, rated for −80 V V_CEO, −1 A continuous collector current, and 0.83 W power dissipation on 1 cm² collector pad. It delivers h_FE = 63–160 at V_CE = −2 V / I_C = −150 mA and is used in high-side switches and MOSFET drivers requiring stable gain and thermal performance.

For engineers reviewing the BC53-10PA,115 datasheet, BC53-10PA,115 pinout, BC53-10PA,115 application, or BC53-10PA,115 equivalent, key selection criteria include verified PNP switching capability at −1 A, thermal resistance of 151 K/W (FR4, 1 cm² collector pad), AEC-Q101 qualification status history, and SOT1061 footprint compatibility with automated assembly.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor optimized for linear and switching applications where high current gain consistency and low saturation voltage are required. Its exposed collector pad enables direct thermal coupling to PCB copper, supporting stable operation up to T_j = 150 °C.

The BC53-10PA variant is defined by its h_FE range (63–160) at −150 mA collector current and −2 V V_CE, distinguishing it from BC53-16PA (100–250) and standard BC53PA (63–250). It uses pulsed test conditions (t_p ≤ 300 μs, δ ≤ 0.02) for h_FE measurement per IEC 60747-1.

FAQ

Is BC53-10PA,115 qualified for automotive use?

No-per Revision 11 (September 2025), BC53-10PA,115 has had its AEC-Q101 qualification status removed. While earlier revisions were qualified, current production is intended for industrial and consumer applications. For automotive-grade alternatives, consult Nexperia's BCP53-Q series or contact Aetrix for qualified replacements.

What is the maximum allowable PCB copper area for the collector pad?

The datasheet specifies thermal performance for collector pads of 1 cm² and 6 cm² on single-sided FR4. Using >6 cm² does not invalidate ratings but yields diminishing returns; the 6 cm² case achieves R_th(j-a) = 114 K/W and P_tot = 1.10 W. No upper limit is defined, but mechanical constraints and layout density typically cap practical area at 6–10 cm².

How does h_FE vary with temperature and current?

h_FE decreases with rising temperature: at −55 °C it exceeds room-temperature values, while at 100 °C it drops significantly (e.g., ~50% reduction at I_C = −500 mA). It also declines at high current-BC53-10PA shows h_FE ≥ 40 at −500 mA, versus 63–160 at −150 mA-requiring conservative base drive design for full-load switching.

Can BC53-10PA,115 replace BC53-16PA in existing designs?

Only with circuit validation. BC53-10PA has lower h_FE (63–160 vs. 100–250 at −150 mA), which may increase base current demand and reduce switching speed in gain-dependent circuits like MOSFET drivers. If the original design uses BC53-16PA near its minimum h_FE, BC53-10PA may cause insufficient drive; verify base resistor value and transient response under worst-case gain.
