Product details

Overview

BCP53-16HX from Nexperia is a PNP medium-power bipolar junction transistor in SOT223 (SC-73) package, rated for −80 V V_CEO, −1 A continuous collector current, and 100–250 DC current gain (h_FE) at −150 mA. It supports high-temperature operation up to +175 °C and is AEC-Q101 qualified for automotive-grade reliability in high-side switch and linear regulator circuits.

For engineers reviewing the BCP53-16HX datasheet, BCP53-16HX pinout, BCP53-16HX application, or BCP53-16HX equivalent, this device is selected for stable high-current switching in thermally constrained PCB layouts where thermal resistance to ambient must be minimized under sustained load conditions.

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown of −80 V and open-emitter collector-base breakdown of −100 V, enabling robust voltage margin in power management rails. Its −7 V V_EBO rating ensures reliable base-emitter junction integrity during reverse-bias transients.

The device delivers −500 mV V_CE(sat) at −500 mA I_C and −50 mA I_B, supporting low-loss switching in MOSFET driver stages. With f_T = 100–140 MHz and C_c = 7 pF at −10 V V_CB, it maintains usable bandwidth for moderate-speed control loops.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V: Maximum safe collector-emitter voltage with base open; defines rail tolerance in high-side switch configurations.
I_C	−1 A continuous: Sustained current-handling capability; enables direct drive of moderate-power loads without heatsinking on standard FR4.
h_FE	100–250 at −150 mA: Tight DC gain binning ensures predictable base drive requirements in linear regulators and amplifiers.
V_CE(sat)	−500 mV max at −500 mA/−50 mA: Low saturation voltage minimizes conduction loss and self-heating in switching applications.
P_tot	1.5 W max (6 cm² collector pad): Thermal performance scales with copper area-critical for automotive under-hood designs.
T_j	+175 °C maximum junction temperature: Enables operation in engine-control modules and power converters near heat sources.
AEC-Q101	Qualified: Meets stress-test requirements for discrete semiconductors in automotive applications per AEC standard.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with four leads: three functional terminals (B, C, E) plus an extended collector tab for enhanced thermal dissipation. The package features a 6.7 mm × 3.7 mm footprint and 1.8 mm height, optimized for reflow soldering and thermal transfer to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; requires current-limited drive to achieve target h_FE-based collector current.
2	Collector	Main current sink path; electrically and thermally connected to exposed metal tab (Pin 4).
3	Emitter	Reference terminal for PNP operation; tied to higher-potential rail in high-side switch topologies.
4	Collector (Tab)	Thermal and electrical extension of Pin 2; must be soldered to ≥1 cm² copper pour for rated power dissipation.

Key Features

Feature	Design Value
Three h_FE bins	BCP53-16H offers 100–250 gain range-enables precise base resistor selection without design iteration across production lots.
AEC-Q101 qualification	Validated for automotive use including temperature cycling, HTRB, and ESD testing-reduces qualification burden for Tier 1 suppliers.
High-temperature operation	+175 °C T_j rating allows placement near power stages or in under-hood ECUs without derating penalties.
Enhanced thermal pad	Exposed collector tab reduces R_th(j-a) to 100 K/W (6 cm² copper), enabling 1.5 W continuous dissipation on standard PCBs.

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
BCP53-10HX	h_FE = 63–160 at −150 mA; lower minimum gain than BCP53-16HX.	Suitable for less sensitive base-drive circuits where gain variation is acceptable.	Select when cost optimization outweighs need for tight gain control in feedback paths.
ZTX951	TO-92 package; −100 V V_CEO, −1.5 A I_C, but no AEC-Q101 qualification or SOT223 thermal pad.	Limited to non-automotive industrial use due to package and qualification gap.	Choose only for prototyping or non-automotive applications where board space and thermal performance are secondary.

Compared with BCP53-10HX, the BCP53-16HX provides higher minimum h_FE for improved base drive predictability; versus ZTX951, it trades TO-92 mechanical simplicity for AEC-Q101 compliance and superior thermal management in SOT223.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is −0.2 A per datasheet limiting values. For reliable long-term operation, keep continuous I_B ≤ −50 mA-this aligns with the −500 mA I_C test condition used for V_CE(sat) specification and avoids thermal runaway in the base-emitter junction.

Can BCP53-16HX replace BCP53-10HX in existing designs?

Yes, pin-to-pin and package-compatible, but h_FE min increases from 63 to 100. This may reduce required base drive current by ~40% in linear applications. Verify stability in feedback loops and confirm that higher gain does not induce oscillation in high-speed switching contexts.

How does thermal performance vary between single-layer and 4-layer PCB mounting?

R_th(j-a) improves from 207 K/W (single-sided, standard footprint) to 69 K/W (4-layer, 1 cm² collector pad). That 3× reduction enables ~2.2 W total power dissipation versus 725 mW-critical for sustained 1 A operation in compact automotive modules.

Is the SOT223 package lead-free and RoHS compliant?

Yes, BCP53-16HX is manufactured using lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The SOT223 package meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard reflow processes.
