Product details

Overview

BCX52,115 from Nexperia is a PNP medium-power surface-mount transistor in SOT89 (SC-62/TO-243) package, rated for −60 V V_CEO, −1 A continuous collector current, and −2 A peak pulse current. It features AEC-Q101 qualification, three h_FE gain selections (63–160 or 100–250), and an exposed heatsink pad for enhanced thermal and electrical conductivity. It is used in high-side switches and MOSFET drivers in automotive power management systems.

For engineers reviewing the BCX52,115 datasheet, BCX52,115 pinout, BCX52,115 application, or BCX52,115 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in linear regulators and battery-driven devices, and confirmed alternatives with documented parameter-level differences.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor optimized for switching and linear amplification in thermally constrained SMD layouts. Its SOT89 package integrates an exposed collector pad that serves both as a thermal path and low-impedance electrical connection, enabling stable operation at up to 0.95 W under 1 cm² copper mounting.

The BCX52,115 supports two h_FE variants (−10 and −16 suffixes), with DC current gain specified at V_CE = −2 V and I_C = −150 mA - 63–160 for selection −10, and 100–250 for selection −16. It exhibits f_T = 145 MHz and C_c = 15 pF, confirming suitability for mid-frequency switching and driver-stage amplification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive and industrial supply rails.
I_C	−1 A continuous: Sustained collector current rating; supports load switching up to ~10 W at moderate duty cycles.
I_CM	−2 A peak (tp ≤ 1 ms): Short-duration surge capability; accommodates inrush currents in power-up sequencing.
h_FE	63–160 (−10) or 100–250 (−16): Gain binning ensures predictable base drive requirements across production lots.
P_tot	0.50 W (standard PCB), 0.95 W (1 cm² copper pad): Power dissipation directly scales with board-level thermal design.
R_th(j-sp)	16 K/W: Junction-to-solder-point thermal resistance confirms efficient heat transfer through the exposed collector pad.
f_T	145 MHz: Transition frequency validates use in >10 MHz switching applications such as gate driving for logic-level MOSFETs.

Pinout & Package

SOT89 (SC-62/TO-243) package with 3 leads and exposed die pad on underside for thermal and electrical conduction. Pin 1 = Emitter, Pin 2 = Collector (connected to exposed pad), Pin 3 = Base.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Primary current exit node; connects to load return or ground reference in high-side switch configurations.
2	Collector	Main current input node and thermal interface; soldered to large copper area for heat dissipation and low-inductance power path.
3	Base	Control input; requires current-limited drive (max −0.3 A continuous) to bias transistor into saturation or active region.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards.
Exposed collector pad	Reduces R_th(j-sp) to 16 K/W and lowers effective thermal resistance by up to 47% vs. standard SOT23 equivalents.
Three h_FE selections	Enables precise base drive optimization: −10 (63–160) for robustness, −16 (100–250) for low-drive sensitivity.
High power dissipation	0.95 W at 1 cm² copper pad allows direct replacement of larger TO-92 or SOT223 transistors in space-constrained designs.
Low V_CE(sat)	≤ −0.5 V at I_C = −500 mA / I_B = −50 mA minimizes conduction loss in high-side switch applications.

Applications

Linear Voltage Regulators

High-Side Switches

Use Scenario: Pass element in adjustable positive LDOs or emitter-follower regulators supplying 3.3 V/5 V rails from 12 V automotive batteries.

IC Role / Device Role / Timing Role: PNP pass transistor controlling output voltage via base bias; no timing function.

Use Value: Low V_CE(sat) reduces dropout voltage; AEC-Q101 rating ensures regulator stability over −40 °C to +125 °C ambient.

Use Scenario: High-side load switch controlling power to infotainment modules or sensor subsystems in ADAS ECUs.

IC Role / Device Role / Timing Role: Main switching element sourcing current from battery rail to load; driven by microcontroller GPIO.

Use Value: Exposed collector pad sustains 0.95 W dissipation during hot-swap events; h_FE binning simplifies base resistor selection.

Battery-Driven Devices

Use Scenario: Power enable control in portable medical monitors or handheld test equipment powered by Li-ion packs.

IC Role / Device Role / Timing Role: Discrete PNP switch isolating main power domain during sleep mode; no signal conditioning.

Use Value: −5 V V_EBO rating prevents reverse-bias damage during battery insertion; low I_CBO (<100 nA) preserves standby current budget.

Use Scenario: Level-shifting driver stage for N-channel high-side MOSFETs in BLDC motor controllers.

IC Role / Device Role / Timing Role: Active pull-down element in totem-pole gate driver configuration; operates in saturation/active transition.

Use Value: 145 MHz f_T supports <100 ns turn-off; low C_c (15 pF) minimizes Miller feedback during fast switching.

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
BCX55,115	Same SOT89 package, but NPN polarity; V_CEO = 60 V, I_C = 1 A, h_FE = 63–250.	Requires circuit topology change (e.g., low-side vs. high-side switching); not drop-in for PNP-based bias networks.	Select only when redesigning for NPN-compatible driver architecture or complementary pair usage.
ZTX753STZ	SOT89 package, PNP, V_CEO = −60 V, I_C = −1 A, but h_FE = 100–300 (no binning) and R_th(j-sp) = 20 K/W.	Lacks AEC-Q101 qualification; higher thermal resistance limits power handling on minimal copper.	Acceptable for industrial non-automotive use where qualification and thermal margin are not critical.

Compared with BCX52,115, BCX55,115 offers polarity inversion rather than functional equivalence, while ZTX753STZ trades automotive qualification and thermal performance for broader h_FE range - making BCX52,115 the sole choice for AEC-Q101–compliant high-side switching with controlled gain bins.

FAQ

What is the maximum allowable junction temperature for BCX52,115?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation beyond this limit causes permanent degradation. Derating curves in the datasheet show usable power decreases linearly above 25 °C ambient, reaching zero at 150 °C junction temperature under standard PCB conditions.

How does the exposed pad on the SOT89 package connect electrically?

The exposed pad on the BCX52,115's SOT89 package is internally connected to the collector terminal (Pin 2). It must be soldered to a dedicated copper pour tied to the collector net - not left floating or grounded - to ensure both thermal performance and correct circuit operation.

Is BCX52,115 suitable for linear amplifier applications?

Yes - its h_FE stability across I_C = −5 mA to −500 mA, low V_CE(sat), and 145 MHz f_T support Class-A and AB audio preamplifier stages and sensor signal conditioning. However, thermal design must accommodate dissipation: at I_C = −150 mA and V_CE = −5 V, P_D ≈ 0.75 W requires ≥1 cm² copper for safe operation.

What marking code identifies BCX52,115 on the device body?

The BCX52,115 is marked with "AE" on the top surface of the SOT89 package. This code corresponds to the base part number BCX52 with standard h_FE selection (63–160), per Table 5 of the Nexperia datasheet Rev. 9.
