Product details

Overview

BC53-16PASX from Nexperia is a PNP medium power transistor in DFN2020D-3 (SOT1061D) package, rated for −80 V V_CEO, −1 A continuous collector current, and 100–250 DC current gain (h_FE) at V_CE = −2 V, I_C = −150 mA. It serves as a high-side switch or MOSFET driver in compact power management circuits with thermal-enhanced side-wettable flanks.

For engineers reviewing the BC53-16PASX datasheet, BC53-16PASX pinout, BC53-16PASX application, or BC53-16PASX equivalent, this device is selected for linear voltage regulation, battery-powered load switching, and low-profile amplifier stages where ultra-thin SMD packaging and visible solder joints are required for AOI and thermal reliability.

Technical Context

This PNP bipolar junction transistor operates in active and saturation regions with defined cutoff characteristics: ICBO ≤ −100 nA at −30 V V_CB, and IEBO ≤ −100 nA at −5 V V_EB. Its transition frequency f_T reaches 145 MHz at −5 V V_CE, −50 mA I_C, enabling use in moderate-speed switching and analog amplification.

Thermal performance depends on PCB layout: R_th(j-a) ranges from 76 K/W (4-layer board + 1 cm² collector pad) to 298 K/W (single-sided FR4 standard footprint). The exposed collector pad provides direct thermal conduction path and electrical connection, supporting stable operation up to T_j = 150 °C.

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
I_C	−1 A - Continuous DC collector current; supports medium-power loads without forced cooling
h_FE	100–250 - Current gain range at −2 V V_CE, −150 mA I_C; enables predictable base drive sizing
V_CE(sat)	≤ −500 mV - Saturation voltage at −500 mA I_C, −50 mA I_B; ensures low conduction loss in switching mode
P_tot	1.65 W - Max power dissipation on 4-layer FR4 with 1 cm² collector pad; sets thermal design boundary
f_T	145 MHz - Transition frequency at −5 V V_CE, −50 mA I_C; supports audio and low-MHz signal amplification
C_c	15 pF - Collector capacitance at −10 V V_CB; influences high-frequency response and switching speed

Pinout & Package

BC53-16PASX uses the DFN2020D-3 (SOT1061D) ultra-thin leadless package: 2 mm × 2 mm × 0.65 mm body, side-wettable flanks for AOI-compatible solder joint inspection, and exposed collector pad for thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter
2	Emitter (E)	Current source terminal; connected to higher potential rail in high-side configurations
3	Collector (C)	Output terminal; electrically and thermally tied to exposed bottom pad for efficient heat transfer

Key Features

Feature	Design Value
Exposed collector pad	Enables direct thermal coupling to PCB copper and low-impedance electrical connection to ground or supply plane
Side-wettable flanks	Supports automated optical inspection (AOI) of solder fillets without X-ray, improving manufacturing yield
Two h_FE bins	BC53-16PASX offers 100–250 h_FE range, allowing precise gain matching in matched-pair or feedback-critical designs
Ultra-thin profile	0.65 mm max height enables use in space-constrained portable and wearable electronics

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
BC807-16W	Same h_FE bin (100–250), but SOT323 package; lower P_tot (0.3 W) and no exposed pad	Limited to <100 mA loads; unsuitable for thermal-intensive high-side switching	Select when board space allows larger footprint and thermal load is minimal
MBT3906DW1T1G	SC-70 package; h_FE 100–300, but only 0.2 W P_tot; no side-wettable flanks	Not AOI-compatible; insufficient for >200 mA continuous operation	Choose only for low-current signal inversion where ultra-small size outweighs thermal needs

Compared with BC807-16W and MBT3906DW1T1G, BC53-16PASX delivers 5× higher power handling and factory-verified AOI support-critical for production-grade battery management and industrial power modules requiring long-term thermal stability.

FAQ

What is the maximum junction temperature and how does it affect PCB layout?

The absolute maximum junction temperature is 150 °C. To maintain safe operation, PCB layout must provide adequate thermal relief: using a 1 cm² copper pad under the exposed collector reduces R_th(j-a) to 76 K/W on 4-layer boards, while standard single-sided FR4 yields 298 K/W-requiring derating above 25 °C ambient.

Is BC53-16PASX suitable for automotive applications?

No. This part is explicitly non-automotive qualified per Nexperia's revision history (v.3, Feb 2024). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, consult Nexperia's BC53-16Q series or equivalent qualified alternatives.

How does the side-wettable flank design improve manufacturing yield?

The side-wettable flanks allow automated optical inspection (AOI) systems to verify solder fillet formation without X-ray imaging. This eliminates blind spots inherent in bottom-terminated packages, reducing false negatives in solder joint quality assessment and increasing first-pass yield in high-volume SMT lines.

What is the significance of the 'CC' marking code on BC53-16PASX?

The 'CC' top-side marking identifies the BC53-16PASX variant per Nexperia's ordering table-distinguishing it from BC53PAS (CA) and BC53-10PAS (CB). This code ensures traceability to the 100–250 h_FE bin and confirms compliance with Rev. 3 (Feb 2024) specifications, including non-automotive qualification status.
