Product details
Overview
BCP53-10H-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, qualified to AEC-Q101 for automotive high-side switches and linear regulators.
For engineers reviewing the BCP53-10H-QX datasheet, BCP53-10H-QX pinout, BCP53-10H-QX application, or BCP53-10H-QX equivalent, this page delivers verified electrical specs, thermal derating behavior, junction-to-ambient thermal resistance under five PCB mounting conditions, and validated automotive-grade reliability data - all critical for power stage design validation and BOM selection.
Technical Context
This PNP transistor operates in linear or saturated switching modes with guaranteed hFE of 63–160 at −150 mA and −2 V, supporting stable current gain across −55 °C to +175 °C ambient. Its dual-collector pin configuration (pins 2 and 4) enables enhanced thermal conduction via extended copper pad routing on FR4 PCBs.
Thermal performance is defined across five mounting configurations: Rth(j-a) ranges from 69 K/W (4-layer PCB, 1 cm² collector pad) to 207 K/W (standard single-sided footprint), directly informing heatsinking strategy. Safe operating area (SOA) is specified for both DC and pulsed conditions up to 2 A peak with tp ≤ 1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum blocking voltage between collector and emitter with base open; defines high-side switch voltage headroom. |
| IC | −1 A - Continuous DC collector current rating; sets maximum steady-state load drive capability. |
| hFE | 63–160 - DC current gain at VCE = −2 V, IC = −150 mA; determines required base drive current for saturation. |
| Ptot | 2.2 W - Total power dissipation on 4-layer FR4 PCB with 1 cm² collector pad; defines thermal limit under worst-case conduction loss. |
| Rth(j-a) | 69 K/W - Junction-to-ambient thermal resistance under optimized 4-layer PCB layout; enables accurate junction temperature prediction. |
| VCE(sat) | −500 mV - Collector-emitter saturation voltage at IC = −500 mA, IB = −50 mA; determines conduction loss in switching applications. |
| fT | 100–140 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; indicates usable bandwidth for small-signal amplification. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads; pins 2 and 4 are internally connected to the collector terminal and serve as thermal and electrical connection points to an extended copper pour for improved power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires current-limited drive to achieve target IC based on hFE. |
| 2 | Collector | Main high-current output path; electrically and thermally tied to pin 4 for parallel routing to PCB copper. |
| 3 | Emiter | Reference node for PNP operation; connects to higher potential rail in high-side switch configurations. |
| 4 | Collector | Second collector terminal; must be soldered to same net as pin 2 to maintain rated power handling and thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications per stress test standard; supports functional safety-aware designs without additional qualification effort. |
| High-temperature operation | Junction temperature rated to +175 °C; enables deployment in engine bay, powertrain, and under-hood modules without derating. |
| Dual-collector thermal path | Pins 2 and 4 both connect to collector; allows doubled copper area attachment for lower Rth(j-a) and higher sustained power capability. |
| Three hFE variants | BCP53-10H-QX offers 63–160 hFE; balances base drive simplicity and gain stability across production lots and temperature. |
| High VCBO | −100 V collector-base breakdown; provides margin against transients and improves robustness in inductive load switching. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |

IC Role / Device Role / Timing Role: High-current PNP switch sourcing gate charge rapidly during turn-on; complements NPN/NMOS driver pairs. Use Value: Enables <100 ns gate drive rise time with −500 mA peak sink capability and minimal Miller plateau distortion due to fT > 100 MHz. |
| High-Side Switches | Power Management |
|
Use Scenario: Load switch controlling 12 V or 24 V battery-fed subsystems (e.g., infotainment power domain, HVAC actuators) in automotive ECUs. IC Role / Device Role / Timing Role: PNP-based high-side switch with integrated base resistor network (external); configured for ON/OFF control with fast transient response.

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 |
|---|---|---|---|
| BCP53-16H-QX | hFE = 100–250 at −150 mA; higher gain but tighter distribution; identical VCEO, IC, package, and thermal specs. | Better suited for low-base-drive systems (e.g., microcontroller GPIO direct drive); less tolerant of hFE variation in production. | Select when base current budget is constrained and gain consistency is prioritized over worst-case drive margin. |
| ZTX951 | TO-92 package; VCEO = −60 V; IC = −1 A; hFE = 100–800; no AEC-Q101 qualification; Rth(j-a) ≈ 250 K/W. | Limited to non-automotive, low-power linear apps; unsuitable for high-temp or high-reliability environments. | Use only in cost-sensitive consumer products where AEC-Q101, thermal performance, and −80 V rating are not required. |
Compared with BCP53-10H-QX, BCP53-16H-QX offers higher and more tightly distributed hFE for reduced base drive, while ZTX951 trades automotive qualification and thermal capability for lower cost and through-hole assembly - making BCP53-10H-QX the optimal balance of gain control, ruggedness, and manufacturability in automotive power stages.

FAQ
What is the maximum allowable junction temperature for BCP53-10H-QX?
The absolute maximum junction temperature is +175 °C, as defined in the limiting values table. Operation at this temperature requires strict adherence to thermal derating curves - for example, total power dissipation must be reduced to ≤1.2 W when mounted on a single-sided FR4 PCB with 1 cm² collector pad at 125 °C ambient.
Can pins 2 and 4 be used independently in circuit layout?
No - pins 2 and 4 are internally shorted to the same collector node. Using them separately violates the device's thermal and electrical specifications. Both must be connected to the same net and preferably routed to a shared copper pour to achieve the rated 2.2 W power dissipation and 69 K/W Rth(j-a).
Is BCP53-10H-QX suitable for pulse-width modulated (PWM) switching above 10 kHz?
Yes - with fT ≥ 100 MHz and VCE(sat) ≤ −500 mV at 500 mA, it supports clean PWM switching up to 500 kHz in low-duty-cycle applications. However, full 1 A switching requires careful attention to SOA limits and thermal management, especially at elevated ambient temperatures.
How does the hFE tolerance affect base resistor selection in a high-side switch design?
With hFE ranging from 63 to 160 at −150 mA, base drive must ensure saturation across the full range: for IC = −1 A, minimum IB = −1 A / 63 ≈ −15.9 mA. A 1 kΩ base resistor from a 5 V logic source delivers −4.5 mA - insufficient; a 270 Ω resistor yields −16.7 mA, guaranteeing hard saturation even at minimum hFE.
