Product details
Overview
BCX53,115 from Nexperia is a PNP medium-power bipolar junction transistor in SOT89 package, rated for −80 V VCEO, −1 A continuous collector current, and 1.35 W power dissipation with 6 cm² copper pad. It delivers hFE = 63–250 at IC = −150 mA and is AEC-Q101 qualified for automotive-grade reliability. Used in high-side switches and MOSFET drivers where robust thermal performance and stable DC gain are required.
For engineers reviewing the BCX53,115 datasheet, BCX53,115 pinout, BCX53,115 application, or BCX53,115 equivalent, this page provides verified electrical parameters, thermal derating curves, pin-confirmed circuit roles, and validated automotive-grade alternatives - all aligned to Nexperia's Rev. 10 (2023) product data sheet.
Technical Context
The BCX53,115 operates as a medium-power PNP BJT with open-base VCEO = −80 V and peak ICM = −2 A (1 ms pulse), enabling use in linear regulators and switching loads up to 1 A. Its exposed collector tab serves as both thermal heatsink and electrical connection, reducing Rth(j-a) to 93 K/W when mounted on 6 cm² FR4 copper.
DC current gain is binned across variants: BCX53 (63–250), BCX53-10 (63–160), and BCX53-16 (100–250) at VCE = −2 V and IC = −150 mA. Transition frequency fT = 145 MHz supports moderate-speed switching applications such as gate driving and audio amplification stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with base open; defines high-side switch voltage headroom. |
| IC | −1 A - Continuous DC collector current rating; supports load switching up to 1 A without forced cooling. |
| Ptot | 1.35 W - Total power dissipation with 6 cm² copper pad; enables stable operation in compact power management PCBs. |
| hFE | 63–250 - DC current gain range at VCE = −2 V, IC = −150 mA; ensures predictable base drive requirements. |
| fT | 145 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; suitable for MOSFET gate driving up to ~10 MHz switching. |
| Rth(j-a) | 93 K/W - Junction-to-ambient thermal resistance with 6 cm² copper; allows ~14 °C/W effective thermal rise per watt. |
| AEC-Q101 | Qualified - Validated for automotive temperature range (−55 °C to +150 °C) and stress testing per discrete semiconductor standard. |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package with 3 leads, 1.5 mm pitch, and 4.5 mm × 2.5 mm × 1.5 mm body. Exposed collector tab provides low-thermal-resistance path to PCB copper and serves as primary heat sink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current exit terminal; connects to load ground or regulated output node in high-side configurations. |
| 2 | Collector (C) | Main power terminal and thermal interface; soldered directly to large copper pour for heat dissipation and low-inductance return path. |
| 3 | Base (B) | Control input; requires −50 mA base drive for full saturation at IC = −500 mA (VCE(sat) ≤ −0.5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Exposed collector tab | Reduces Rth(j-a) to 93 K/W with 6 cm² copper; eliminates need for external heatsink in 1 W applications. |
| Three hFE bins | BCX53 (63–250), BCX53-10 (63–160), BCX53-16 (100–250); enables precise base resistor selection across production lots. |
| AEC-Q101 qualification | Validated for automotive ambient range (−55 °C to +150 °C) and HTRB/ACLT stress tests; supports under-hood deployment. |
| High VCBO | −100 V collector-base rating; provides margin against transients in 48 V battery systems and industrial power rails. |
| Low VBE | −1 V typical at IC = −500 mA; simplifies bias network design and reduces base drive power loss. |

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 |
|---|---|---|---|
| BCP53,115 | Same SOT89 package, identical VCEO = −80 V and IC = −1 A, but hFE binning differs (63–250 vs. 100–250 for BCX53-16 variant only). | Not AEC-Q101 qualified; limited to industrial/commercial temperature range (−55 °C to +150 °C not guaranteed). | Select when automotive qualification is unnecessary and cost sensitivity outweighs qualification overhead. |
| ZTX753 | TO-92 package, VCEO = −60 V, IC = −1 A, hFE = 100–300; lacks exposed thermal pad and AEC-Q101 status. | Lower thermal performance (Rth(j-a) ≈ 200 K/W); unsuitable for sustained >0.5 W operation without heatsink. | Choose only for prototyping or low-power legacy designs where SOT89 footprint is unavailable. |
Compared with BCX53,115, BCP53,115 offers identical electrical specs but no automotive qualification, while ZTX753 trades thermal efficiency and package compatibility for wider hFE spread and through-hole assembly - making BCX53,115 the sole choice for thermally constrained, AEC-Q101–compliant high-side switching.

FAQ
What is the maximum allowable junction temperature for BCX53,115?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Derating is required above Tamb = 25 °C: Ptot decreases linearly to zero at 150 °C ambient when mounted on 6 cm² copper (1.35 W → 0 W over 125 °C range).
Does BCX53,115 require a heatsink in typical applications?
No external heatsink is required when mounted on ≥6 cm² of 1 oz copper on FR4 PCB, where Rth(j-a) = 93 K/W enables full 1.35 W dissipation with ≤125 °C junction rise. For >0.8 W continuous use on smaller pads, thermal vias or increased copper area are recommended.
How does the BCX53,115 differ from BCX53-16?
BCX53,115 is the base variant with hFE = 63–250 at IC = −150 mA; BCX53-16 is a binned version with tighter hFE = 100–250. Both share identical VCEO, IC, package, and AEC-Q101 qualification - the difference lies solely in DC gain distribution for precision biasing.
Can BCX53,115 be used in avalanche mode?
No - BCX53,115 is not rated or characterized for controlled avalanche operation. Its absolute maximum VCEO = −80 V is a hard limit; exceeding it risks irreversible breakdown. Transient suppression must be handled externally via TVS diodes or clamping circuits.
