Product details

Overview

BCP53-16,135 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 1.35 W power dissipation with 6 cm² copper pad. It delivers h_FE = 100–250 at V_CE = −2 V and I_C = −150 mA, optimized for high-side switching and linear regulation in battery-powered industrial power management systems.

For engineers reviewing the BCP53-16,135 datasheet, BCP53-16,135 pinout, BCP53-16,135 application, or BCP53-16,135 equivalent, this part supports precise DC current gain selection, thermal-aware PCB layout via defined mounting pad requirements, and robust saturation performance (V_CE(sat) ≤ −0.5 V at I_C = −500 mA / I_B = −50 mA) in non-automotive power control designs.

Technical Context

This PNP transistor operates in active, saturation, and cutoff regions with verified absolute maximum ratings: −100 V V_CBO, −5 V V_EBO, and 150 °C T_j. Its pulsed I_CM reaches −2 A (t_p ≤ 1 ms), supporting transient load handling in power sequencing circuits.

Thermal resistance varies significantly with PCB copper area: R_th(j-a) = 93 K/W (6 cm² pad), 125 K/W (1 cm²), or 192 K/W (standard footprint). Transient Z_th(j-a) curves confirm stable thermal response under 0.02 duty-cycle pulses, enabling reliable MOSFET gate drive in intermittent high-current bursts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V - Maximum safe collector-emitter voltage with base open; defines high-side switch blocking capability in 48 V systems.
I_C	−1 A - Continuous DC collector current rating; supports sustained 1 A load switching without derating at T_amb ≤ 25 °C.
h_FE	100–250 - Confirmed DC current gain range at V_CE = −2 V, I_C = −150 mA; enables predictable base drive sizing for linear regulators.
V_CE(sat)	≤ −0.5 V - Measured at I_C = −500 mA, I_B = −50 mA; ensures low conduction loss in saturated high-side switches.
f_T	145 MHz - Transition frequency at V_CE = −5 V, I_C = −50 mA; supports fast switching in PWM-driven amplifier stages.
P_tot	1.35 W - Max power dissipation with 6 cm² copper pad; requires specific PCB thermal design to sustain full-rated current.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and 6.5 mm × 3.5 mm × 1.65 mm body dimensions. Collector terminals are internally paralleled on pins 2 and 4 for enhanced thermal and current-handling capability.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; requires current-limited drive (I_B ≤ −0.3 A) to avoid damage during switching transients.
2	Collector	Main high-current output terminal; electrically tied to pin 4 for doubled current path and lower thermal resistance.
3	Emitter	Reference node for PNP operation; connected to system supply rail in high-side switch configurations.
4	Collector	Second collector terminal; must be soldered to same copper pour as pin 2 to maintain specified R_th(j-a) and current rating.

Key Features

Feature	Design Value
Three h_FE variants	BCP53-16 offers 100–250 gain range-enables precise base resistor selection for consistent turn-on behavior across production batches.
Enhanced thermal dissipation	1.35 W P_tot with 6 cm² copper pad-supports higher ambient temperatures than standard SOT223 transistors in compact power modules.
Parallel collector terminals	Pins 2 and 4 both serve as collector-reduces effective bond wire resistance and improves current sharing in high-pulse applications.
High V_CBO rating	−100 V collector-base voltage-provides margin against voltage spikes in inductive load switching (e.g., solenoid drivers).

Applications

Linear Voltage Regulators

High-Side Switches

Use Scenario: Adjustable positive-output LDO using PNP pass transistor with op-amp error amplifier.

IC Role / Device Role / Timing Role: PNP pass element controlling output voltage by modulating emitter current based on feedback loop demand.

Use Value: Low V_CE(sat) (≤ −0.5 V) minimizes dropout voltage; wide h_FE range allows stable loop compensation across temperature.

Use Scenario: 24 V/48 V bus isolation for microcontroller-peripheral power domains.

IC Role / Device Role / Timing Role: High-side switch enabling/disabling downstream loads with logic-level base drive.

Use Value: −80 V V_CEO provides headroom for load-dump transients; parallel collectors reduce on-resistance and thermal stress.

Battery-Driven Devices

MOSFET Drivers

Use Scenario: Power path control in portable medical monitors with Li-ion battery input.

IC Role / Device Role / Timing Role: Reverse-polarity protection and battery disconnect switch in main power rail.

Use Value: −1 A continuous rating supports peak sensor burst currents; −5 V V_EBO ensures safe operation during hot-swap events.

Use Scenario: Level-shifting driver for N-channel MOSFETs in half-bridge motor controllers.

IC Role / Device Role / Timing Role: Fast-turn-off PNP stage pulling gate to supply rail when high-side FET must be disabled.

Use Value: 145 MHz f_T enables sub-100 ns turn-off; low C_c (15 pF) minimizes Miller effect during switching transitions.

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
BCP52-16,115	Lower V_CEO (−60 V) and reduced P_tot (1.00 W with 1 cm² pad); otherwise identical h_FE range and pinout.	Suitable only for ≤ 36 V systems; less thermal headroom in high-ambient environments.	Select when cost sensitivity outweighs voltage/thermal margin needs in 24 V applications.
ZTX753STZ	Higher V_CEO (−100 V), TO-92 package, no parallel collector terminals; h_FE = 100–300 at I_C = −100 mA.	Through-hole mounting limits board density; lacks SOT223's thermal pad scalability.	Choose for legacy through-hole designs requiring higher voltage rating but accepting manual assembly and lower power density.

Compared with BCP52-16,115 and ZTX753STZ, the BCP53-16,135 uniquely combines −80 V blocking, 1.35 W dissipation with scalable copper pads, and dual-collector SOT223 packaging-making it optimal for space-constrained, thermally demanding high-side power control where surface-mount reliability is critical.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is −0.3 A per the limiting values table. For reliable long-term operation, base current should be limited to ≤ −50 mA under typical switching conditions to avoid thermal runaway and ensure h_FE stability across temperature. Pulse base current up to −0.3 A is permitted only for t_p ≤ 1 ms with duty cycle ≤ 0.02.

Can BCP53-16,135 be used in automotive applications?

No-this device is explicitly marked as non-automotive qualified in the revision history. It has not undergone AEC-Q101 testing or qualification for automotive use. Nexperia offers separate −Q qualified variants (e.g., BCP53-16Q) for automotive applications; BCP53-16,135 must not be deployed in safety-critical or vehicle-mounted systems.

How does the dual-collector configuration affect PCB layout?

Pins 2 and 4 are internally connected to the same collector node and must be soldered to a single, shared copper pour. Splitting them across isolated traces invalidates the thermal resistance specifications and risks uneven current distribution, localized overheating, and premature failure. The recommended footprint uses one large thermal pad connecting both pins.

What is the significance of the "135" suffix in BCP53-16,135?

The "135" denotes the specific tape-and-reel packaging variant: 1000 pieces per reel, 12 mm tape width, and EIA-481-D compliant embossed carrier tape. It does not indicate electrical or thermal differences from other BCP53-16 variants-only packaging format and reel quantity for automated SMT placement.
