Product details
Overview
BCP53-10-QX from Nexperia is a PNP medium-power bipolar junction transistor in SOT223 (SC-73) package, rated for −80 V VCEO, −1 A continuous collector current, and 160 hFE at −150 mA/−2 V, optimized for high-side switching and linear voltage regulation in automotive-grade power management circuits.
For engineers reviewing the BCP53-10-QX datasheet, BCP53-10-QX pinout, BCP53-10-QX application, or BCP53-10-QX equivalent, this device supports thermally robust operation on FR4 PCBs with up to 1.35 W dissipation (6 cm² collector pad), delivers low VCE(sat) of −0.5 V at −500 mA/−50 mA drive, and meets AEC-Q101 for under-hood automotive use.
Technical Context
This PNP transistor operates as a saturated switch or linear amplifier with fixed polarity, requiring negative base-emitter bias to conduct. Its hFE range (63–160) enables predictable current gain control across −5 mA to −500 mA collector loads at 25 °C.
Thermal performance is defined by three mounting configurations: standard footprint (192 K/W Rth(j-a)), 1 cm² collector pad (125 K/W), and 6 cm² pad (93 K/W), enabling design-specific derating per Fig. 1. Junction temperature is limited to 150 °C with ambient operating range from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with open base; defines high-side switch voltage headroom in 24 V automotive systems. |
| IC | −1 A - Continuous DC collector current rating; supports load switching up to ~12 W at 12 V with adequate heatsinking. |
| hFE | 63–160 - DC current gain at VCE = −2 V, IC = −150 mA; determines required base drive current for saturation (e.g., −1 mA base for −150 mA collector). |
| VCE(sat) | −0.5 V max at IC = −500 mA, IB = −50 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| Ptot | 1.35 W - Max power dissipation with 6 cm² copper pad; sets thermal design boundary for PCB layout and airflow requirements. |
| fT | 145 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; supports moderate-speed switching (e.g., <500 kHz PWM) without excessive delay. |
| Rth(j-a) | 93 K/W - Thermal resistance junction-to-ambient with 6 cm² collector pad; used to calculate ΔTj = P × Rth for reliability margining. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package: 6.5 mm × 3.5 mm × 1.65 mm body, 2.3 mm lead pitch, integrated heatsink tab (Pin 4 = Collector), rated for reflow and wave soldering per Figures 10–11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires negative bias relative to emitter to enable conduction; typical drive current ≤ −50 mA for full saturation. |
| 2 | Collector (C) | Main current output path; electrically tied to Pin 4; must be connected to large copper area for thermal management. |
| 3 | Emitter (E) | Reference terminal; connects to higher potential rail in high-side configuration; carries full load current. |
| 4 | Collector (C) | Dual-collector terminal; internal connection to Pin 2; serves as primary thermal interface and current return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard; supports deployment in engine control, body electronics, and ADAS subsystems. |
| Three hFE variants | BCP53-10-QX provides mid-range gain (63–160); enables consistent biasing across production lots without recalibration. |
| High power dissipation | 1.35 W with 6 cm² copper pad; allows direct replacement of TO-223 or DPAK devices in space-constrained layouts. |
| Low VCE(sat) | ≤ −0.5 V at rated IC/IB; reduces conduction loss by >30% vs. legacy PNP transistors with >−0.7 V saturation. |
| Thermally optimized SOT223 | Collector tab (Pin 4) provides low-impedance thermal path; Rth(j-sp) = 16 K/W to solder point enables rapid heat extraction. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
|
Use Scenario: Adjustable LDO pre-regulator stage in automotive infotainment power supply, delivering 5 V/1 A from 12 V battery input. IC Role / Device Role / Timing Role: Pass transistor controlling output voltage via feedback loop; operates in linear mode with constant VCE ≈ −7 V. Use Value: Low VCE(sat) and stable hFE ensure ±2% output regulation across temperature and load, minimizing dropout and thermal drift. |
Use Scenario: Ignition coil driver in 12 V gasoline engine ECU, switching 500 mA load at 100 Hz. IC Role / Device Role / Timing Role: High-side switch sinking current from coil to ground; driven by microcontroller GPIO through base resistor. Use Value: −80 V VCEO withstands inductive kickback spikes up to −60 V; fast fT ensures clean turn-off with minimal tail current. |
| Battery-Driven Devices | MOSFET Drivers |
|
Use Scenario: Load disconnect switch in portable medical monitor powered by Li-ion battery (3.0–4.2 V). IC Role / Device Role / Timing Role: Reverse-polarity protection and soft-start control; placed between battery and main DC-DC converter input. Use Value: −5 V VEBO rating prevents emitter-base breakdown during hot-swap events; low leakage (<100 nA ICBO) preserves standby battery life. |
Use Scenario: Level-shifting gate driver for N-channel MOSFET in 24 V industrial motor controller H-bridge. IC Role / Device Role / Timing Role: Pull-down stage translating 3.3 V logic to −24 V gate drive; paired with NPN companion for complementary output. Use Value: Matched hFE binning (63–160) ensures consistent rise/fall timing; dual-collector package handles pulsed IC up to −2 A. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP53-16-QX | Higher hFE range (100–250) at same test conditions; identical VCEO, IC, and package. | Better suited for low-base-drive designs (e.g., microcontroller GPIO directly driving base without buffer). | Select when base current budget is ≤ −1 mA at IC = −150 mA; avoid if gain stability over temperature is critical. |
| ZTX951 | TO-92 package; −80 V VCEO, −1 A IC, but lower Ptot (0.8 W) and no AEC-Q101 qualification. | Limited to non-automotive, low-power linear amplification; unsuitable for high-duty-cycle switching. | Choose only for cost-sensitive consumer prototypes where thermal margin and automotive compliance are not required. |
Compared with BCP53-10-QX, BCP53-16-QX offers higher gain for reduced drive complexity but narrower hFE tolerance; ZTX951 sacrifices thermal capability and automotive qualification for through-hole assembly and lower unit cost.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is −0.3 A per Table 5. However, for reliable long-term operation at IC = −1 A, base current should be limited to −100 mA to maintain VCE(sat) ≤ −0.5 V and prevent thermal runaway. Pulse operation allows up to −0.3 A for tp ≤ 1 ms with duty cycle ≤ 2%.
Can BCP53-10-QX replace BCP53-16-QX in an existing design?
Yes, mechanically and electrically - same package, voltage/current ratings, and pinout. However, hFE is lower (63–160 vs. 100–250), so base drive may need adjustment: increase IB by ~1.6× to achieve equivalent IC in saturation. Verify VCE(sat) and thermal rise under worst-case load.
Is the SOT223 thermal pad (Pin 4) required to be soldered for functional operation?
Yes - Pin 4 is internally connected to the collector and serves as the primary thermal path. Leaving it unsoldered increases Rth(j-a) from 93 K/W to 192 K/W, reducing max power handling by >50%. IPC-compliant soldering to ≥6 cm² copper is mandatory for rated 1.35 W operation.
Does BCP53-10-QX support operation at −40 °C ambient?
Yes - the specified Tamb range is −55 °C to +150 °C. At −40 °C, hFE decreases by ~15% versus 25 °C (per Fig. 5), and VBE increases by ~0.1 V (per Fig. 7). Designers must verify sufficient base drive margin and adjust bias networks accordingly for cold-start functionality.
