Product details
Overview
BCP53-10TX 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 1.3 W power dissipation on 4-layer PCB with 1 cm² collector pad. It delivers hFE = 63–160 at VCE = −2 V and IC = −150 mA, and is AEC-Q101 qualified for automotive-grade reliability in high-side switch and linear regulator applications.
For engineers reviewing the BCP53-10TX datasheet, BCP53-10TX pinout, BCP53-10TX application, or BCP53-10TX equivalent, this page provides verified pin functions, thermal derating curves, safe operating area (SOA) boundaries, hFE vs. temperature/collector current behavior, and validated automotive-grade alternatives.
Technical Context
The BCP53-10TX operates as a PNP switching and linear amplification device with open-base VCEO = −80 V and pulsed ICM = −2 A (tp ≤ 1 ms). Its DC current gain is binned to 63–160 at −150 mA, enabling predictable biasing in feedback-controlled regulators and gate drivers.
Thermal performance is defined across five mounting conditions: Rth(j-a) ranges from 70 K/W (4-layer PCB, 1 cm² collector pad) to 209 K/W (standard FR4 single-sided copper), directly impacting maximum ambient operating temperature and continuous power handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum collector-emitter voltage before breakdown with base open; defines high-side switch voltage headroom. |
| IC | −1 A - Continuous DC collector current rating; supports MOSFET driver stages and 1 A linear regulator pass elements. |
| hFE | 63–160 - Guaranteed DC current gain at VCE = −2 V, IC = −150 mA; enables stable bias design without gain margin overdesign. |
| Ptot | 1.3 W - Max power dissipation on FR4 4-layer PCB with standard footprint; sets thermal pad layout requirements. |
| fT | 100–140 MHz - Transition frequency at VCE = −5 V, IC = −50 mA, f = 100 MHz; supports >10 MHz switching control loop compensation. |
| VCE(sat) | −500 mV - Collector-emitter saturation voltage at IC = −500 mA, IB = −50 mA; determines conduction loss in saturated-switch applications. |
| Rth(j-a) | 70 K/W - Junction-to-ambient thermal resistance on 4-layer FR4 with 1 cm² collector pad; defines max ΔTj-a under load. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads: pins 1 (base), 2 (collector), 3 (emitter), and 4 (collector). The dual-collector configuration improves thermal conduction and current sharing in high-power linear operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on. |
| 2 | Collector | Main current sink terminal; electrically tied to pin 4 for enhanced thermal and current capacity. |
| 3 | Emitter | Reference and current source terminal; connected to higher potential in high-side configurations. |
| 4 | Collector | Second collector connection-parallel to pin 2-to reduce thermal resistance and increase safe operating area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood applications per stress test standard, including temperature cycling, HTRB, and ESD. |
| Three hFE bins | BCP53-10TX specifically offers 63–160 gain range-tighter than generic transistors-reducing calibration overhead in precision current mirrors. |
| Dual-collector SOT223 | Pins 2 and 4 both connect to collector, lowering effective thermal resistance by ~15% vs. single-collector variants and improving SOA at high IC. |
| High VCEO / VCBO | −80 V VCEO and −100 V VCBO support 24 V and 48 V industrial bus regulation and 60 V transient-tolerant high-side switching. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|
|
Use Scenario: Pass element in adjustable LDOs delivering up to 1 A at 3.3 V–12 V output from 15–48 V input rails. IC Role / Device Role / Timing Role: PNP series pass transistor controlling output voltage via feedback loop; no timing function. Use Value: −80 V VCEO allows 48 V input with 20 V headroom; −500 mV VCE(sat) minimizes dropout and thermal load at full load. |
Use Scenario: Level-shifting and current-boosting stage driving N-channel MOSFET gates in half-bridge motor controllers. IC Role / Device Role / Timing Role: High-side level shifter and gate current amplifier; operates in saturation and active regions during transitions. Use Value: Dual-collector thermal path sustains 1 A peak gate charge current; hFE bin ensures consistent turn-on delay across production lots. |
| High-Side Switches | Power Management |
|
Use Scenario: Load switch for automotive body electronics (e.g., lighting, HVAC actuators) requiring reverse-polarity and load-dump protection. IC Role / Device Role / Timing Role: Main switching element controlled by microcontroller GPIO through base resistor network; no internal timing. Use Value: AEC-Q101 qualification guarantees operation at −40 °C to +150 °C ambient; −2 A ICM handles inrush and short-circuit pulses. |
Use Scenario: Current-sense amplifier front-end and battery disconnect switch in portable medical devices and industrial sensors. IC Role / Device Role / Timing Role: Precision current mirror reference transistor and low-leakage isolation switch; operates in active and cutoff regions. Use Value: −100 nA ICBO at 25 °C ensures <1 µA standby leakage; 100–140 MHz fT supports fast fault detection response in current-limit circuits. |
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 |
|---|---|---|---|
| BCP53-16TX | hFE = 100–250 (vs. 63–160); otherwise identical VCEO, IC, package, and thermal specs. | Better suited for low-base-drive applications (e.g., microcontroller-driven switches with limited GPIO current). | Select when base drive current is constrained below −10 mA and tighter gain consistency above 100 is required. |
| ZTX951 | TO-92 package, −100 V VCEO, −1.5 A IC, but only 0.8 W Ptot; no AEC-Q101 qualification. | Limited to non-automotive, lower-power linear applications due to thermal and qualification gaps. | Choose only for cost-sensitive consumer designs where AEC-Q101 and SOT223 thermal performance are not required. |
Compared with BCP53-10TX, the BCP53-16TX offers higher and narrower hFE for reduced base drive burden, while ZTX951 trades automotive qualification and thermal capability for lower cost and higher voltage rating in through-hole form-neither is pin-compatible nor drop-in.

FAQ
What is the maximum allowable junction temperature for BCP53-10TX?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet Limiting Values table. Operation must remain within this limit under all conditions-including worst-case ambient, power dissipation, and PCB thermal resistance-to ensure long-term reliability and avoid permanent degradation.
Is BCP53-10TX pin-compatible with other SOT223 PNP transistors like MMBT5336?
No-BCP53-10TX has a 4-pin SOT223 pinout (B-C-E-C), whereas MMBT5336 uses a 3-pin SOT223 (B-C-E). Pin 4 on BCP53-10TX is a second collector connection, not a dummy pad. Physical and electrical incompatibility prevents direct substitution without PCB redesign.
Does BCP53-10TX support pulsed operation beyond its DC current rating?
Yes-its peak collector current (ICM) is −2 A for single pulses ≤1 ms, as confirmed in Table 2 and Table 6. This enables use in short-duration overload protection, inrush limiting, and gate-driving transients where average power remains within Ptot limits.
How does the dual-collector configuration affect PCB layout?
The dual-collector (pins 2 and 4) must be connected to the same copper pour-ideally an extended thermal pad-for optimal heat transfer. The recommended reflow footprint (Fig. 19) specifies a 6.15 mm × 7 mm solder land covering both collector pads, ensuring mechanical stability and minimizing thermal resistance to the board.
