Product details

Overview

BCX52-16,135 from Nexperia is a PNP medium power transistor in SOT89 (SC-62) surface-mount package, rated for −60 V V_CEO, −1 A continuous collector current, and 0.50 W power dissipation on standard FR4 PCB. It features h_FE selection of 100–250 at V_CE = −2 V and I_C = −150 mA, AEC-Q101 qualification, and exposed heatsink for thermal management. Used in linear voltage regulators and high-side switches in automotive and industrial power management.

For engineers reviewing the BCX52-16,135 datasheet, BCX52-16,135 pinout, BCX52-16,135 application, or BCX52-16,135 equivalent, this page delivers verified electrical specs, thermal derating behavior, SOT89 terminal mapping, and validated alternatives for PNP switching and amplification in constrained-space designs.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor with fixed-emitter configuration in SOT89 package, where the collector connects to the exposed die pad for enhanced thermal conduction. Its DC current gain is binned to h_FE = 100–250 at −150 mA, enabling predictable biasing in linear regulator pass elements and MOSFET gate drivers.

It supports peak collector currents up to −2 A (single pulse, t_p ≤ 1 ms), exhibits V_CE(sat) ≤ −0.5 V at I_C = −500 mA/I_B = −50 mA, and maintains f_T = 145 MHz - confirming suitability for low-to-moderate frequency switching and analog amplification up to ~100 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage under open-base condition; defines breakdown margin in high-side switch applications.
I_C	−1 A continuous: Rated DC collector current; determines maximum load-handling capability in linear regulators and battery-driven devices.
h_FE (−150 mA)	100–250: Confirmed DC current gain range for BCX52-16 variant; enables stable bias design without external gain compensation.
P_tot (std FR4)	0.50 W: Total power dissipation on single-sided FR4 with standard footprint; sets thermal layout requirements for PCB copper area.
R_th(j-a)	250 K/W: Junction-to-ambient thermal resistance on standard FR4; used to calculate temperature rise under steady-state load.
f_T	145 MHz: Transition frequency at V_CE = −5 V, I_C = −50 mA; confirms usable bandwidth for fast-switching driver stages.
V_CE(sat)	≤ −0.5 V at I_C = −500 mA/I_B = −50 mA: Low saturation voltage minimizes conduction loss in high-side switching configurations.

Pinout & Package

SOT89 (SC-62/TO-243) plastic surface-mounted package with exposed die pad for thermal and electrical conductivity; 3-terminal leadless outline measuring 4.6 × 2.6 × 1.8 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Primary current exit path; connected to system ground or low-side reference in high-side switch topologies.
2	Collector	Main current input node and thermal interface; soldered to large copper pour for heat extraction and low-impedance return path.
3	Base	Control input for current amplification; requires series resistor to limit I_B ≤ −0.3 A per absolute maximum rating.

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	Enables direct thermal coupling to PCB copper; reduces R_th(j-a) by up to 63% when using 1 cm² mounting pad.
Three h_FE selections	BCX52-16 bin ensures consistent gain matching across production lots, reducing calibration overhead in precision current sources.
High power dissipation	0.95 W achievable with 1 cm² collector pad on FR4 - supports higher ambient temperatures in enclosed industrial enclosures.
Low V_BE	≤ −1.0 V at I_C = −500 mA: Reduces base drive power requirement in high-current switching applications.

Applications

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 complement with +60 V V_CEO, +1 A I_C, and h_FE = 100–250; not electrically interchangeable.	Used in low-side switching and NPN-based amplifier stages - requires circuit topology change.	Select only when redesigning for NPN logic compatibility or complementary pair implementation.
ZTX753STZ	TO-92 package, −60 V V_CEO, −1 A I_C, h_FE = 100–300, but R_th(j-a) = 300 K/W (no exposed pad); lower power handling.	Limited to low-power, non-automotive applications due to lack of AEC-Q101 and inferior thermal performance.	Acceptable only for cost-sensitive consumer prototypes where board space and thermal margin are not constrained.

Compared with BCX52-16,135, BCX55,115 offers complementary NPN functionality but requires full schematic revision, while ZTX753STZ sacrifices AEC-Q101 compliance and thermal efficiency for legacy through-hole compatibility - neither matches the SOT89 automotive-grade balance of gain stability, power density, and reliability.

FAQ

What is the exact h_FE range for BCX52-16,135?

The BCX52-16,135 is binned to h_FE = 100–250 at V_CE = −2 V and I_C = −150 mA, as confirmed in Table 2 and Table 8 of the official Nexperia datasheet Rev. 9. This is distinct from BCX52-10 (63–160) and applies exclusively to the "-16" suffix variant.

Can BCX52-16,135 be used in place of BCX52-10,135?

Yes, but only if the circuit tolerates higher minimum h_FE. BCX52-16 guarantees h_FE ≥ 100, whereas BCX52-10 guarantees only ≥ 63. In bias-critical applications like precision current mirrors, substituting may alter operating point and require recalculating base resistors.

Is the SOT89 package lead-free and RoHS compliant?

Yes - BCX52-16,135 is manufactured in a lead-free, RoHS-compliant SOT89 package per Nexperia's standard process. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard reflow profiles per Figure 24 in the datasheet.

What is the maximum allowable PCB copper area for optimal thermal performance?

With a 6 cm² collector pad on single-sided FR4, BCX52-16,135 achieves R_th(j-a) = 93 K/W and P_tot = 1.35 W (Table 6). This configuration allows sustained 1 A operation at 70 °C ambient - exceeding the 0.50 W standard rating by 170%.
