Product details

Overview

BCP53HX from Nexperia is a PNP medium power transistor in SOT223 (SC-73) package, rated for −80 V V_CEO, −1 A continuous collector current, and 1.5 W max power dissipation on 6 cm² copper pad. It features AEC-Q101 qualification, 175 °C junction temperature rating, and three h_FE variants (63–250), enabling use in automotive-grade high-side switches and linear voltage regulators.

For engineers reviewing the BCP53HX datasheet, BCP53HX pinout, BCP53HX application, or BCP53HX equivalent, this page delivers verified electrical parameters, thermal derating behavior, safe operating area boundaries, and validated alternatives for high-reliability power control designs.

Technical Context

This device operates as a single PNP bipolar junction transistor with base-controlled current amplification. Its −80 V V_CEO and −100 V V_CBO support robust blocking in 24 V and 48 V automotive power rails, while its −2 A I_CM peak rating enables short-duration surge handling in MOSFET driver stages.

Thermal performance is defined across five PCB mounting configurations: R_th(j-a) ranges from 69 K/W (4-layer board, 1 cm² collector pad) to 207 K/W (standard single-sided FR4). The fixed 4-pin SOT223 layout uses dual collector terminals (pins 2 and 4) to reduce thermal resistance and improve current sharing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V - Maximum sustainable collector-emitter voltage with base open; defines safe operation in 48 V systems with margin.
I_C	−1 A - Continuous DC collector current at T_amb ≤ 25 °C; usable up to 175 °C junction temperature with derating.
h_FE	63–250 - DC current gain at V_CE = −2 V, I_C = −150 mA; enables precise base drive sizing for switching or linear regulation.
V_CE(sat)	−500 mV - Saturation voltage at I_C = −500 mA, I_B = −50 mA; determines conduction loss in high-side switch applications.
P_tot	1.5 W - Max power dissipation on FR4 PCB with 6 cm² collector copper pad; sets thermal design baseline for heatsinkless layouts.
f_T	100–140 MHz - Transition frequency at V_CE = −5 V, I_C = −50 mA; supports fast switching in driver circuits up to ~10 MHz.
R_th(j-a)	69–207 K/W - Junction-to-ambient thermal resistance across five PCB configurations; critical for thermal simulation accuracy.

Pinout & Package

SOT223 (SC-73) plastic surface-mounted package with 4 leads, featuring an extended copper tab for enhanced thermal conduction. Dual collector pins (2 and 4) are internally connected to the same die region and must be soldered to a common thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; requires current-limited drive to achieve target I_C based on h_FE range.
2	Collector	Primary high-current output terminal; electrically tied to pin 4 and thermal pad for low-inductance, low-resistance path.
3	Emiter	Reference node for load connection; connects to supply rail in high-side switch configuration.
4	Collector	Secondary collector terminal; must be routed to same net as pin 2 to maintain specified thermal and current ratings.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive underhood applications per stress test requirements, including temperature cycling and HTRB.
175 °C maximum junction temperature	Enables operation in engine control units and powertrain modules without external cooling.
Dual collector terminals (pins 2 & 4)	Reduces effective thermal resistance by 30% vs. single-collector SOT223 variants when both pins are properly connected.
Three h_FE selections (BCP53-10H/BCP53-16H)	Allows optimization of base drive strength and switching speed trade-offs across production batches and system tolerances.
−2 A peak collector current (I_CM)	Supports transient load surges in power management ICs and gate drivers without secondary protection circuitry.

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
ZTX951	Higher V_CEO (−100 V), lower I_C (−0.5 A), TO-92 package, no AEC-Q101 qualification	Not suitable for automotive underhood use; limited thermal capability due to leaded package	Select only for non-automotive, low-power linear regulation where footprint flexibility outweighs thermal needs.
BC807-40	Same SOT-23 package, lower V_CEO (−45 V), lower I_C (−0.5 A), no dual collector, AEC-Q101 qualified	Insufficient voltage rating for 48 V systems; inadequate current for high-side switch loads >300 mA	Use only in 12 V/24 V logic-level switching where space constraints prohibit SOT223.

Compared with ZTX951 and BC807-40, BCP53HX uniquely combines AEC-Q101 compliance, −80 V blocking, −1 A current, and dual-collector thermal enhancement-making it the sole option for thermally constrained, high-voltage automotive power switching.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current (I_B) is −0.2 A per datasheet Table 6. For reliable long-term operation, design base drive to limit I_B to ≤ −50 mA at I_C = −500 mA, ensuring saturation without excessive power dissipation in the base-emitter junction.

Can BCP53HX replace BCP53-16H in existing designs?

Yes-BCP53HX is the generic part number covering all BCP53H variants, including BCP53-16H. It shares identical package, pinout, voltage/current ratings, and thermal characteristics; only h_FE distribution differs. No layout or schematic changes are required.

How does the dual-collector configuration affect PCB layout?

Pins 2 and 4 must be connected to the same copper pour, ideally a ≥1 cm² thermal pad with ≥4 thermal vias to inner ground/power planes. Separating them degrades thermal resistance by up to 40% and risks current imbalance, violating the specified P_tot rating.

Is BCP53HX compatible with lead-free reflow profiles?

Yes-Nexperia specifies full compatibility with JEDEC J-STD-020D.2 Class 3 reflow profiles, including peak temperatures up to 260 °C for 30 seconds. The SOT223 package passes MSL-1 classification with unlimited floor life when stored per datasheet handling guidelines.
