Product details

Overview

BCX53-10,115 from Nexperia is a PNP medium power transistor in SOT89 package, rated for −80 V V_CEO, −1 A continuous collector current, and 1.35 W power dissipation with 6 cm² copper pad. It delivers h_FE = 63–160 at −150 mA/−2 V and is AEC-Q101 qualified for automotive-grade reliability. It serves as a high-side switch or linear regulator pass element in battery-powered industrial control modules.

For engineers reviewing the BCX53-10,115 datasheet, BCX53-10,115 pinout, BCX53-10,115 application, or BCX53-10,115 equivalent, key selection criteria include verified thermal resistance (R_th(j-a) = 93 K/W with 6 cm² pad), pulsed current capability (−2 A, t_p ≤ 1 ms), saturation voltage (V_CEsat ≤ −0.5 V at −500 mA/−50 mA), and AEC-Q101 qualification status.

Technical Context

This PNP bipolar junction transistor operates in linear or saturated switching modes, with base-emitter turn-on threshold near −1 V and transition frequency f_T = 145 MHz at −50 mA/−5 V. Its exposed collector tab enables direct thermal coupling to PCB copper, supporting stable operation up to T_j = 150 °C.

The device features three h_FE gain bins (BCX53, BCX53-10, BCX53-16); BCX53-10 provides mid-range DC current gain (63–160) optimized for predictable biasing in MOSFET driver stages and regulated power rails where gain consistency across temperature (−55 to +150 °C) is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V - Maximum safe collector-emitter voltage with open base; supports 48 V automotive and industrial bus regulation.
I_C	−1 A continuous - Sustained load current handling for high-side switches driving solenoids or LED arrays.
P_tot	1.35 W with 6 cm² copper pad - Enables compact thermal design without external heatsink in space-constrained PCBs.
h_FE	63–160 at −150 mA/−2 V - Mid-bin gain ensures stable bias point in linear regulators and amplifier feedback networks.
R_th(j-a)	93 K/W with 6 cm² pad - Confirmed thermal path efficiency allows full power operation at ambient ≤ 57 °C.
f_T	145 MHz - Supports high-speed switching in gate drive applications up to ~10 MHz square-wave edge rates.
V_CEsat	≤ −0.5 V at −500 mA/−50 mA - Low saturation loss reduces conduction heating in active-low control paths.

Pinout & Package

SOT89 (SC-62) flat-lead surface-mount package with 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, and exposed collector tab for thermal and electrical grounding.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit node; connects to system ground or low-side return path in high-side configurations.
2	Collector	Exposed metal tab - primary thermal interface and high-current input node; must be soldered to ≥6 cm² copper for rated power.
3	Base	Control input; requires −50 mA drive for full saturation at −500 mA load; compatible with 3.3 V/5 V logic via series resistor.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood use (−40 to +125 °C ambient, 150 °C junction), including temperature cycling and HTRB.
Exposed collector tab	Direct thermal path to PCB copper reduces R_th(j-a) by 40% vs standard footprint - enables 1.35 W dissipation without heatsink.
Three h_FE gain bins	BCX53-10 bin (63–160) provides tighter gain distribution than generic transistors, simplifying bias network design.
High peak current rating	−2 A single-pulse (t_p ≤ 1 ms) supports inrush current limiting in power-up sequencing circuits.
Low V_BE variation	−1 V typical at −500 mA ensures predictable base drive requirements across temperature and production lot.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP53-10,115	Same SOT89 package, identical V_CEO/I_C/h_FE specs, but lower P_tot = 1.25 W (6 cm² pad) and no AEC-Q101 qualification.	Not approved for automotive safety-critical functions; suitable for industrial non-automotive linear regulators.	Select when AEC-Q101 is not required and cost sensitivity outweighs qualification overhead.
ZTX753	TO-92 package, −100 V V_CEO, h_FE = 100–300, P_tot = 1.0 W; lacks exposed thermal tab and AEC-Q101 rating.	Requires through-hole assembly and external heatsinking; limited to low-density PCBs with manual assembly.	Choose only if TO-92 form factor is mandated and thermal derating to 0.75 W is acceptable.

Compared with BCP53-10,115 and ZTX753, BCX53-10,115 uniquely combines AEC-Q101 qualification, SOT89 thermal performance (1.35 W), and controlled h_FE binning-making it the sole option for automotive high-side switches requiring both reliability and power density.

FAQ

What is the maximum allowable junction temperature for BCX53-10,115?

The absolute maximum junction temperature is 150 °C per IEC 60134. Operation at this limit requires strict thermal design: 6 cm² copper pad, ambient ≤ 57 °C, and derated power per Fig. 1. Exceeding 150 °C causes irreversible parametric shift and accelerated failure.

Can BCX53-10,115 replace BCX53-16 in a circuit?

No-BCX53-10 has h_FE = 63–160 while BCX53-16 offers 100–250. Substituting without recalculating base resistors risks insufficient drive in saturation or excessive base current in linear mode, leading to thermal runaway or poor regulation.

Is the exposed collector tab electrically isolated from other pins?

No-the collector (Pin 2) is the exposed metal tab and is electrically connected to the collector semiconductor region. It must be tied to the same potential as the collector net and cannot serve as a floating thermal pad; isolation requires insulating thermal interface material.

Does BCX53-10,115 require a base resistor in switching applications?

Yes-a series base resistor is mandatory to limit I_B to ≤ −0.3 A (absolute max) and ensure reliable saturation. For −500 mA I_C, a 100 Ω resistor with 5 V drive yields −50 mA I_B, meeting the h_FE-based design rule of I_B ≥ I_C/10.
