Product details
Overview
BCX52-16,115 from Nexperia is a PNP medium power transistor in SOT89 (SC-62) surface-mount package, rated for −60 V VCEO, −1 A continuous collector current, and 0.50 W power dissipation on standard FR4 PCB. It features hFE selection group −16 (100–250 at VCE = −2 V, IC = −150 mA), AEC-Q101 qualification, and exposed die pad for thermal and electrical conductivity. It serves as a high-side switch or linear regulator pass element in automotive and industrial power management.
For engineers reviewing the BCX52-16,115 datasheet, BCX52-16,115 pinout, BCX52-16,115 application, or BCX52-16,115 equivalent, key selection considerations include its PNP polarity, −60 V breakdown rating, hFE binning, thermal resistance (Rth(j-a) = 250 K/W on standard FR4), and SOT89 mechanical footprint compatibility with high-side switching layouts.
Technical Context
This device operates as a saturated or linear-mode PNP bipolar junction transistor with fixed emitter-base and collector-emitter junction architecture. Its design supports DC-coupled high-side switching where base drive is referenced to the supply rail, and it delivers stable current gain across −55 °C to +150 °C ambient range.
Thermal performance is defined by junction-to-ambient resistance (250 K/W standard, 93 K/W with 6 cm² copper pad) and junction-to-solder-point resistance (16 K/W), enabling predictable derating in compact power stages. The SOT89 package integrates an exposed collector pad that serves dual roles: low-inductance current path and primary heat conduction path to PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail tolerance in high-side switch designs. |
| IC | −1 A - Continuous DC collector current; sets maximum load capability in linear regulators or driver stages. |
| hFE (−16 bin) | 100–250 at VCE = −2 V, IC = −150 mA - Tighter gain spread enables consistent base drive sizing across production units. |
| Ptot | 0.50 W on standard FR4 - Power handling limit without heatsink; requires thermal pad layout for >0.95 W operation. |
| Rth(j-a) | 250 K/W (standard FR4) - Thermal resistance baseline for ambient temperature rise estimation in enclosure-constrained designs. |
| VCE(sat) | −0.5 V at IC = −500 mA, IB = −50 mA - Saturation voltage determines conduction loss and heat generation in switching applications. |
| fT | 145 MHz - Transition frequency confirms suitability for moderate-speed switching (≤100 kHz PWM) and analog amplification up to audio band. |
Pinout & Package
SOT89 (SC-62/TO-243) plastic surface-mounted package with exposed collector pad for enhanced thermal and electrical performance; 3-terminal leadless outline measuring 4.6 × 4.4 × 1.8 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Reference terminal for PNP current flow; connected to load return or ground in high-side configuration. |
| 2 | Collector | Main power output node; electrically and thermally tied to exposed pad for low-resistance PCB heat sinking. |
| 3 | Base | Control input requiring negative bias relative to emitter; drives transistor into saturation or active region. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and ESD robustness per JESD22 standards. |
| Three hFE selections | Bin codes −10 (63–160), −16 (100–250), and unmarked (63–250) enable precise base resistor selection across production lots. |
| Exposed collector pad | Provides <16 K/W junction-to-solder-point thermal path and low-inductance collector connection for stable high-current operation. |
| High power dissipation capability | Supports 0.95 W with 1 cm² copper pad and 1.35 W with 6 cm² pad-enabling compact thermal design without external heatsinks. |
| Medium power SMD form factor | SOT89 balances PCB area (≈20 mm²), thermal performance, and manufacturability for automated reflow assembly. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
Use Scenario: Adjustable LDO or series pass element in 12 V automotive systems with 5 V or 3.3 V output. IC Role / Device Role / Timing Role: PNP pass transistor regulating output by varying emitter-collector conduction in response to error amplifier feedback. Use Value: −60 V rating accommodates load-dump transients; hFE binning ensures predictable dropout and thermal behavior across temperature. |
Use Scenario: Controlling 12 V loads (e.g., solenoids, lamps) directly from microcontroller GPIO via level-shifting base driver. IC Role / Device Role / Timing Role: High-side power switch turning on/off load between battery rail and ground-return path. Use Value: Exposed collector pad minimizes thermal impedance during pulsed loads; −1 A rating supports typical automotive actuators. |
| Battery-Driven Devices | MOSFET Drivers |
Use Scenario: Reverse-polarity protection or battery disconnect circuit in portable medical or industrial handheld equipment. IC Role / Device Role / Timing Role: PNP configured as reverse-voltage blocking switch in series with battery positive terminal. Use Value: Low VCE(sat) (−0.5 V) reduces voltage drop and power loss in always-on protection paths. |
Use Scenario: Level-shifting and current-boosting stage driving N-channel MOSFET gates in half-bridge motor controllers. IC Role / Device Role / Timing Role: Active pull-up device sourcing gate charge rapidly while sinking leakage during off-state. Use Value: 145 MHz fT ensures fast turn-on/turn-off transitions; AEC-Q101 qualification supports automotive motor control environments. |
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 VCEO, +1 A IC, and matched hFE bins. | Requires inverted control logic and low-side placement; unsuitable for high-side or reverse-polarity use cases. | Select when NPN topology is preferred or complementary pairing is needed in push-pull drivers. |
| ZTX788B | TO-92 through-hole package, −80 V VCEO, −2 A IC, hFE 100–300, no AEC-Q101 qualification. | Larger footprint and lower thermal efficiency on PCB; not qualified for automotive under-hood deployment. | Choose only for prototyping or non-automotive industrial applications where higher voltage margin justifies manual assembly. |
Compared with BCX52-16,115, BCX55,115 offers complementary NPN functionality in identical packaging but cannot replace PNP-specific high-side roles, while ZTX788B trades AEC-Q101 compliance and SMT manufacturability for higher voltage/current ratings in through-hole form.

FAQ
What is the hFE range for BCX52-16,115 and how is it binned?
The BCX52-16,115 is binned to hFE selection group −16, guaranteeing a DC current gain of 100–250 at VCE = −2 V and IC = −150 mA. This binning is laser-marked as "AM" on the device top surface and enables consistent base resistor calculation across production lots without gain variation testing.
Can BCX52-16,115 be used in linear regulator applications with 24 V input?
Yes - its −60 V VCEO rating provides 36 V headroom above 24 V input, accommodating transients and ripple. However, power dissipation must be limited to ≤0.50 W on standard FR4; for 24 V → 5 V @ 500 mA (9.5 W theoretical loss), external heatsinking or parallel devices are required to stay within thermal limits.
Is the exposed pad on the SOT89 package electrically connected, and how should it be handled?
Yes - the exposed pad is internally connected to the collector terminal. It must be soldered to a dedicated PCB copper pour (≥1 cm² recommended) for both electrical continuity and thermal conduction. Floating or unconnected pads cause thermal runaway and premature failure under load.
Does BCX52-16,115 support reflow-only assembly, and what is the maximum peak temperature?
Yes - reflow soldering is the only recommended method per Nexperia documentation. Peak temperature must not exceed 260 °C for ≤30 seconds (JEDEC J-STD-020 compliant), with ramp rates ≤3 °C/s pre-peak and cooling rate ≤6 °C/s post-peak to avoid package delamination or solder joint fracture.
