Product details
Overview
BCX53-10TF from Nexperia is a PNP bipolar power transistor in SOT89 (SC-62) package, rated for −80 V VCEO, −1 A continuous collector current, and 1100 mW power dissipation with 6 cm² copper pad. It delivers hFE = 63–160 at VCE = −2 V and IC = −150 mA, and is AEC-Q101 qualified for automotive-grade reliability. It serves as a high-side switch or MOSFET driver in linear voltage regulators and power management circuits.
For engineers reviewing the BCX53-10TF datasheet, BCX53-10TF pinout, BCX53-10TF application, or BCX53-10TF equivalent, this page provides verified pin functions, thermal derating curves, hFE binning details, saturation voltage behavior under pulsed conditions, and validated automotive-grade alternatives - all critical for robust high-current switching design in constrained PCB layouts.
Technical Context
This PNP transistor operates in active or saturation mode with fixed emitter-base and collector-base junctions. Its −80 V VCEO rating enables use in 24 V and 48 V industrial bus systems, while its −2 A ICM peak current supports short-duration load switching transients. The device's hFE bin (−10T) ensures predictable base drive requirements across production lots.
Thermal performance is defined by mounting-dependent Rth(j-a): 114 K/W with 6 cm² collector pad, enabling sustained 1 A operation at Tamb ≤ 75 °C. Its fT = 140 MHz and Cc = 7 pF support moderate-speed switching up to ~10 MHz with controlled Miller effect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter voltage with open base; defines maximum supply rail compatibility in high-side configurations. |
| IC | −1 A continuous: Sustained DC collector current capability; sets upper bound for steady-state load switching in regulators or drivers. |
| hFE | 63–160 at VCE = −2 V, IC = −150 mA: Confirmed current gain range for −10T bin; determines required base drive current for saturation. |
| VCE(sat) | −500 mV max at IC = −500 mA, IB = −50 mA: Verified saturation voltage; directly impacts conduction loss and thermal rise in switching applications. |
| Ptot | 1100 mW with 6 cm² copper pad: Maximum power dissipation limit; requires specific PCB layout for full-rated current handling. |
| fT | 140 MHz typical at VCE = −5 V, IC = −50 mA: Transition frequency confirming usable bandwidth for medium-speed control loops and gate driving. |
| AEC-Q101 | Qualified: Meets stress test requirements for automotive discrete semiconductors; supports deployment in engine control, body electronics, and ADAS subsystems. |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package: 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, with exposed collector tab for thermal conduction. Mounting pad area directly governs power dissipation capability (114 K/W at 6 cm²).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit node; connected to higher potential rail in high-side switch configuration; must be routed with low-inductance path for fast turn-off. |
| 2 | Collector | Main current sink node; electrically and thermally tied to large copper pad; serves as primary heat transfer interface to PCB. |
| 3 | Base | Control input; requires current-limited drive (≤ −200 mA DC, ≤ −300 mA pulse) to avoid damage and ensure reliable saturation. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE bins | BCX53-10T (63–160), BCX53-16T (100–250), BCX53T (63–250): Enables precise base drive sizing and consistent switching timing across production batches. |
| High power dissipation | 1100 mW with 6 cm² pad: Supports 1 A continuous operation without external heatsink in space-constrained industrial modules. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C) and stress tests: Enables drop-in use in automotive power stages without requalification. |
| Medium-power SOT89 footprint | Standardized 3-pin SMD outline with thermal pad: Simplifies layout reuse across Nexperia's BCX53/BCX56 family and reduces BOM fragmentation. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|

Use Scenario: Pass transistor in adjustable positive LDOs delivering up to 1 A output current with <1 % line regulation. IC Role / Device Role / Timing Role: PNP pass element controlling output voltage via emitter-follower configuration; base driven by error amplifier. Use Value: −80 V VCEO allows wide input range (e.g., 12–48 V); −500 mV VCE(sat) minimizes dropout voltage and improves efficiency at full load. |
Use Scenario: Level-shifting driver stage for N-channel high-side MOSFETs in half-bridge motor controllers. IC Role / Device Role / Timing Role: Active pull-down switch that rapidly discharges MOSFET gate during turn-off; complements NPN pre-driver. Use Value: −2 A ICM handles gate charge surge; 140 MHz fT ensures sub-100 ns switching transitions for PWM frequencies up to 20 kHz. |
| High-Side Switches | Power Management |
|
Use Scenario: Load switch for 24 V battery-fed subsystems (e.g., infotainment power rails, sensor clusters) requiring reverse polarity protection. IC Role / Device Role / Timing Role: Main current-handling switch placed between supply and load; base driven by microcontroller GPIO through current-limiting resistor. Use Value: −1 A IC supports typical automotive loads; AEC-Q101 qualification guarantees operation over full vehicle temperature profile. |
Use Scenario: Current-sense amplifier front-end or bias generator in multi-rail PMICs for industrial PLCs and programmable logic controllers. IC Role / Device Role / Timing Role: Precision current mirror reference or stable bias current source for op-amp input stages. Use Value: Tight hFE bin (63–160) ensures ±5 % current matching; low VBE drift (<1 mV/°C) maintains accuracy across −40 °C to +105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCX53-16TF | Higher hFE bin (100–250) at same VCE/IC; otherwise identical ratings and package. | Reduces required base drive current by ~40 % vs. −10T; beneficial where MCU GPIO current is limited. | Select when lower base current demand outweighs tighter hFE tolerance needs. |
| ZTX951 | Same SOT89 package but −100 V VCEO, −1.5 A IC, and 1500 mW Ptot; hFE = 100–300 (unbinned). | Supports higher-voltage rails (e.g., 72 V telecom) and greater continuous current; no AEC-Q101 qualification. | Choose for non-automotive industrial applications needing extended voltage/current headroom. |
Compared with BCX53-10TF, BCX53-16TF offers higher gain for reduced drive burden, while ZTX951 trades automotive qualification for higher voltage/current margins - making each suitable for distinct system-level trade-offs in thermal, drive, and compliance requirements.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current (IB) is −200 mA per the limiting values table. For reliable long-term operation, design base drive to stay below −150 mA continuous, especially when ambient temperature exceeds 75 °C. Pulse operation up to −300 mA is permitted for durations ≤1 ms with duty cycle ≤2 %.
How does PCB copper area affect thermal performance?
Thermal resistance Rth(j-a) varies from 250 K/W (standard footprint) to 114 K/W (6 cm² collector pad). Using the 6 cm² pad enables full 1 A current at Tamb ≤ 75 °C; reducing pad area to 1 cm² raises junction temperature by ~35 °C at same current, requiring derating to ~0.7 A for safe operation.
Is BCX53-10TF suitable for switching 48 V loads?
Yes - its −80 V VCEO rating provides 32 V margin above 48 V nominal systems, accommodating transients and ripple. However, ensure VCE never exceeds −80 V during turn-on/off transitions, and verify gate drive timing in MOSFET driver applications to prevent shoot-through-induced overvoltage.
What does the "−10" suffix indicate in BCX53-10TF?
The "−10" denotes the hFE gain bin: guaranteed 63–160 at VCE = −2 V and IC = −150 mA. This binning allows designers to select base resistors with confidence, ensuring consistent saturation across production units without individual device characterization.
